May Was Hottest on Record ("1.38 deg F above global avg; El Nino isn't even here yet!")

May Was Hottest on Record ("1.38 deg F above global avg; El Nino isn't even here yet!") | Climate & Clean Air Watch | Scoop.it
Average temperature rose 1.38 degrees.

According to NASA, the average global temperature for May was 1.38 degrees Fahrenheit above average, making it the hottest on record. And, these record highs come before El Niño, which is expected to hit this summer. The global average does not mean it was scorching everywhere—for instance, Texas had a colder-than-average May—but it is significant in terms of long-term temperatures. In addition to NASA, the Japan Meteorological Agency said that March, April, and May of 2014 were the warmest on record, dating back to 1891.

Bert Guevara's insight:

Hottest on record!!!

Wow, we are resetting all warmest records since 1891.

This map explains why climate change is so unfair ("the poor get hit harder than the guilty rich") | Climate & Clean Air Watch | Scoop.it
The world's poorest countries are also the ones most likely to get hammered by the earth's warming. Can the new EPA regulations do anything about that?

They also might be Obama's greatest contribution to the fight against global poverty. Climate change is bad for everyone. But it's particularly bad for the world's poorest.

Standard and Poor's, the credit rating company, recently published a report assessing the risk each country faces from climate change. You'll notice the more vulnerable (redder) countries cluster in Asia and Africa, while the better off (greener) countries are almost all in North America or Europe:

The cost to the developing world of unmitigated climate change will be staggering. Assume the globe warms by about four degrees celsius, which is easily possible absent major emissions reductions. Those notorious hippies at the World Bank suggest that this could lead to massive increases in disease, extreme storms, droughts, and flooding. The effects will be so massive, according to the bank's President Jim Kim, that they could roll back "decades of development gains and force tens of more millions of people to live in poverty."

Bert Guevara's insight:

Climate Injustice! The impact of climate change is not fair to the world. The "guilty" rich will mostly be spared from the immediate onslaught, while the "Innocent" poor will get hit hard.

The Philippines belongs to the Top 10 most vulnerable countries to the adverse impacts of climate change.

EPA Aims To Slash Power Plant CO2 by 30 Percent | Climate Central ("congrats for the guts, Mr. Pres")

EPA Aims To Slash Power Plant CO2 by 30 Percent | Climate Central ("congrats for the guts, Mr. Pres") | Climate & Clean Air Watch | Scoop.it
Obama aims to slash CO2 pollution from the electric power sector by 30 percent below 2005 levels by 2030.

The proposed new rule, scheduled to go into effect in June 2015 after a period of public comment, would apply to about 3,000 electricity generating units at 1,000 power plants nationwide and aims to reduce pollutants that contribute to soot and smog by 25 percent by 2030. 

The rule is the second of two climate change-related rules affecting the coal industry and the electric power sector. The first, which the EPA proposed last fall, aims to cap emissions from unbuilt coal-fired power plants. But the rule the agency proposed Monday is more controversial because it would require existing coal-fired power plants to cut their carbon emissions.

Specifically, the rule proposes a unique carbon emissions reduction guideline for each state, and each state would have to create its own plan to achieve that goal by the end of June 2016. For nearly each state, the EPA is requiring two sets of emissions reductions goals for power plants: one goal allowing for the final emissions reduction goal to be phased in during the 2020s and then a final reduction goal for 2030.

Bert Guevara's insight:

This is a big step for the environment, coming from a country that has many law makers believing that climate change is a "political ideology."

I wonder what the opposition will do.

Solar plane makes inaugural flight ("cleaning the air industry by reinventing the airplane - go solar")

Solar plane makes inaugural flight ("cleaning the air industry by reinventing the airplane - go solar") | Climate & Clean Air Watch | Scoop.it
Solar Impulse 2, a solar-powered plane that will attempt a global flight in 2015, takes to the skies above Switzerland for the first time.

"It's a great day for all the team of Solar Impulse," Mr Piccard told BBC News.

"An aeroplane like this is absolutely unique. And for the first time in history, we have an aeroplane that is flying with no fuel day and night, showing the incredible potential of the clean technologies - all these technologies that the world can also use in order to reduce the dependency to fossil fuel and to be cleaner and solve a lot of problems of pollution."

The carbon-fibre aircraft has a huge wingspan, which at 72m is wider than a Boeing 747 jet. And yet, the vehicle weighs only 2.3 tonnes.

The tops of the wings are covered by 17,000 solar cells, which drive four brushless electric motors at speeds of up to 140km/h (90mph).

During the day, the solar cells will recharge lithium batteries, which can then be used to keep the plane’s propellers turning through the night.

Bert Guevara's insight:

The airline industry has been criticized for polluting the atmosphere because of fuel emissions that are hardly monitored. 

Going solar is a revolutionary way to go. This solar plane will debut in 2015 and many are watching with eagerness for its success.

Organic Farming ‘Could Sequester All Carbon Emissions’ · Environmental Management & Energy News · Environmental Leader

Organic Farming ‘Could Sequester All Carbon Emissions’ · Environmental Management & Energy News · Environmental Leader | Climate & Clean Air Watch | Scoop.it
Environmental Leader

Achieving these goals would require the wholesale adoption of the practice of  “regenerative farming,” an organic farming technique that the study, Regenerative Organic Agriculture and Climate Change, describes as “widely available and inexpensive.”

In 2012, total annual global emissions of greenhouse gases were approximately 52 GtCO2e. These emissions must soon drop to a net of 41 GtCO2e a year if we are to have a feasible chance of limiting warming to 1.5°C, according to the study.

If management of all current cropland shifted to reflect the regenerative model outlined in the study, it would potentially sequester more than 40 percent of annual emissions (an estimated 21 GtCO2 each year). If, at the same time, all global pasture was managed to a regenerative model, an additional 71 percent (~37 GtCO2) might be sequestered, bringing the world into an annual negative emissions scenario “rapidly,” the study says.

Adopting regenerative organic agriculture practices on just half of cropland and pasture would sequester enough emissions to meet the 41 GtCO2e a year threshold, the study says.

... Crucially, organically grown crops can produce greater yields during droughts than traditionally grown crops. Organic corn yields, for example, are around 31 percent higher in drought than non-organic corn yields, the study says.

 

Bert Guevara's insight:

Check the numbers!!! -- "regenerative farming" (a form of organic farming) can potentially sequester 40% of annual global emissions that accelerate climate change. If you include pasture land, this may sequester an additional 71%. This can bring the world to an annual negative emissions scenario.

This is a fantastic proposal, which can also increase food production. This initiative should be pursued on a larger scale.

Governor Wants To Wean Utilities Off Coal ("the citizens of Washington want to be coal-free")

Governor Wants To Wean Utilities Off Coal ("the citizens of Washington want to be coal-free") | Climate & Clean Air Watch | Scoop.it
SEATTLE (AP) — With an abundant supply of hydroelectric power, Washington state currently gets less than 14 percent of its electricity from coal.

Gov. Jay Inslee wants to take that down to zero over time....

Saying the state has a moral responsibility to act on climate change, Inslee signed an executive order last month directing state agencies to negotiate with utilities to phase out electricity produced from coal.

"It's not a trivial activity by any means, but I think it can be done," said Tony Usibelli, director of Washington's energy office, on eliminating coal-fired electricity from the state's fuel mix.

The state's only coal-fired power plant, the TransAlta facility in Centralia, is slated to shut down by 2025. Most of the state's coal-fired electricity, or coal by wire, is imported from the Colstrip power plant in eastern Montana and the Jim Bridger plant in Wyoming.

One elected official in Montana recently criticized Inslee's proposal as job-killing, while environmentalists cheered it as a big step toward making Washington coal-free.

... "We're going to look at the data, look at the information, look at modeling," Danner said. "But utilities themselves are aware of what their customers want. The people in Washington want to be coal-free."

Bert Guevara's insight:

Why not ask the people what they want re their source of power? In this state, the voice of the people is clear.

"We're going to look at the data, look at the information, look at modeling," Danner said. "But utilities themselves are aware of what their customers want. The people in Washington want to be coal-free."

Southeast Australia Endures Fall Heat Wave After Another Record-Breaking Summer ("new warm normal?")

Southeast Australia Endures Fall Heat Wave After Another Record-Breaking Summer ("new warm normal?") | Climate & Clean Air Watch | Scoop.it
The warm fall does come one the heels of another “angry summer” in Australia.

These temperatures aren’t high enough to cause major problems in the cities, besidesprompting Sydney officials to keep swimming pools open longer than they usually do. But the warm fall does come on the heels of another “angry summer” in Australia, one that broke156 temperature records in the country. In 2014, Sydney suffered through its driest summer in 27 years, Perth had its second-hottest summer on record, and Adelaide sweltered through a record 11 days at or above 107.6°F. Officials were also forced to halt the 2014 Australian Open after temperatures reached 110°F.

A report from Australia’s Climate Council, the privately-funded group that issues reports on the effects climate change is having in Australia, found that eight of the country’s hottest summers have occurred in the past 15 years. That intense heat and dryness has made bushfire season more dangerous — last year, for instance, New South Wales declared a state of emergency after bushfires destroyed 200 homes, with fires raging in conditions officials said were the most dangerous in 40 years.

April Was 2nd Warmest Globally; Average for U.S. | Climate Central ("350 months in a row! yes sweat!")

April Was 2nd Warmest Globally; Average for U.S. | Climate Central ("350 months in a row! yes sweat!") | Climate & Clean Air Watch | Scoop.it
April was the 2nd warmest on record globally, the 350th month in a row with above-average temperatures.

That makes April the 350th month in a row — more than 29 years — with above-average temperatures, largely caused by the buildup of manmade greenhouse gases in Earth’s atmosphere.

According to the latest NASA data, the planet’s average April temperature was 58.5°F — 1.3°F above the average temperature from 1951-1980. That ranks behind only April 2010 in the warmest Aprils on record. In particular, Europe and Asia saw an extremely warm month.

“Even though the start to this year was cold, that long-term warming trend is there,” Crouch said.

The pattern that kept the eastern U.S. cool is an example of a signal that can have a regional influence, but that doesn’t overwhelm the larger trend of global warming, Crouch said.

Thirdhand Smoke Causes DNA Damage, ‘May Cause Cancer’ ("smoking dangers live beyond 2nd hand smoke!")

Thirdhand Smoke Causes DNA Damage, ‘May Cause Cancer’ ("smoking dangers live beyond 2nd hand smoke!") | Climate & Clean Air Watch | Scoop.it
Do you know about the dangers of thirdhand smoke? Studies have indicated that thirdhand smoke can lead to DNA changes and cancer.

According to Hang, thirdhand smoke—or the residue from smoking found on surfaces and in dust in a room or area where someone previously smoked—can produce toxicants that undergo chemical changes when they encounter compounds in the air. One of these compounds created by thirdhand smoke is 4-(Methylnitrosamino)-4-(3-pyridyl)-butanal, or “NNA”.

NNA, says Hang and his colleagues, can attach itself to DNA and create a cancer-causing chemical, according to MedicalNewsToday.

NNA and another compound known as NNK break down DNA, damaging it in such a way that leads to uncontrolled cell growth and the possible formation of tumors.

While Hang’s research is still in its early stages, he says we have only begun to understand the full damage that thirdhand smoke can cause. Babies and toddlers may be most at risk of these dangers because they are still developing and because they are most likely to swallow, touch, and inhale these compounds as they crawl around, touching everything in their path and frequently putting their hands in their mouths.

Bert Guevara's insight:

Cigarette residue harms us even beyond its smoke-life. Revealing!!!

Shell, Adidas, And 70 Other Companies Call On Governments To Cap Carbon At 1 Trillion Tons ("urgent!")

Shell, Adidas, And 70 Other Companies Call On Governments To Cap Carbon At 1 Trillion Tons ("urgent!") | Climate & Clean Air Watch | Scoop.it
This is the emissions cap needed to keep warming below two degrees Celsius according to the latest IPCC report.

Royal Dutch Shell, Adidas, Unilever, and some 70 other companies released a communiqué urging world governments to keep carbon emissions since the industrial revolution to a cumulative of 1 trillion metric tons. This is the emissions cap needed to keep warming below two degrees Celsius and avoid catastrophic impacts of climate change, according to the latest Intergovernmental Panel on Climate Change (IPCC) report, which for the first time calls for a trillion ton cap. We have already surpassed the halfway mark and are somewhere around 578,935,750,000 tonnes of carbon at the moment. If the current rate of emissions keeps up, the limit will be passed within three decades.

The statement was released by the Prince Charles’s Corporate Leaders Group on Climate Change, a group of companies brought together by the heir to the British throne and managed by the University of Cambridge. The statement is asking for a timeline to reduce emissions to net zero by 2100. It also states that “we will have to reformulate our relationship with energy and completely transform our energy system, including energy used in transport and heavy industrial processes.”

They cite President Obama’s call to end U.S. public financing for new coal-fired power plants overseas and the World Bank and the European Investment Bank similar announcements as evidence of a growing international effort to limit emissions.

Bert Guevara's insight:

Who are the people behind these giant corps? Don't they live in the same planet as everyone else?

"A study last year found that just 90 companies are responsible for two-thirds of global greenhouse gas emissions since the industrial revolution. These companies, which include Shell, Chevron, Exxon, and other oil and gas companies have the power to do more than endorse government action, but in many cases they fail to do so — continuing to pursue the most profitable path forward."

In Developing World, Pollution Kills More Than Disease - Truth-Out ("dirty air & water kill more")

In Developing World, Pollution Kills More Than Disease - Truth-Out ("dirty air & water kill more") | Climate & Clean Air Watch | Scoop.it
In Developing World, Pollution Kills More Than Disease
Truth-Out
Uxbridge, Canada - Pollution, not disease, is the biggest killer in the developing world, taking the lives of more than 8.4 million people each year, a new analysis shows.

“Toxic sites along with air and water pollution impose a tremendous burden on the health systems of developing countries,” said Richard Fuller, president of the Pure Earth/Blacksmith Institute, which prepared the analysis as part of The Global Alliance on Health and Pollution (GAHP). GAHP is a collaborative body of bilateral, multilateral, and international agencies, national governments, academia and civil society.

Air and chemical pollution is growing rapidly in these regions and when the total impact on the health of people is also considered, “the consequences are dire,” Fuller told IPS.

This future is entirely preventable as most developed countries have largely solved their pollution problems. The rest of the world needs assistance, but pollution has dropped off the radar in the current draft of the Sustainable Development Goals (SDGs), he said.

The SDGs are the U.N.’s new plan for development assistance for the next 15 years. Countries, aid agencies and international donors are expected to align their funding and aid with these goals when they are announced in September 2015.

Bert Guevara's insight:

We know this but the truth has to be repeated often enough.

“Pollution is sometimes called the invisible killer…its impact is difficult to track because health statistics measure disease, not pollution,” Fuller said.

As a result, pollution is often misrepresented as a minor issue, when it actually needs serious action now, he said.

Another big EPA court victory -- this time on soot pollution ("no permit to asthma & heart attacks")

Another big EPA court victory -- this time on soot pollution ("no permit to asthma & heart attacks") | Climate & Clean Air Watch | Scoop.it
It's the third notable environmental court win in a month, upholding the EPA's right to clamp down on particulates that cause heart attacks and asthma.

The U.S. Court of Appeals for the D.C. Circuit ruled that the EPA acted properly in 2012 when it further restricted allowable soot emissions. It was the Obama administration’s third big environmental legal victory in a month. And experts say that bodes well for the administration’s efforts to clamp down on climate-changing emissions from power plants. The L.A. Times explains:

 

The 11-page decision rejected industry complaints and found that the EPA had acted reasonably and within its bounds when it adopted stricter nationwide standards for fine particulate matter. The tiny, chemical-laden particles and liquid droplets are emitted by power plants, diesel trucks, refineries and factories. They lodge deep in the lungs when inhaled and are linked to heart and lung disease, respiratory illnesses and premature deaths. …

Based on scientific studies, the EPA tightened annual limits on fine particle pollution from 15 micrograms per cubic meter to 12 micrograms per cubic meter and set new requirements for dozens of major cities to install air quality monitors to test for the pollutants near busy roadways.

Bert Guevara's insight:

Obama administration's 3rd big environmental legal victory!

‘Climate Change Is Here’: Australia Experiences Hottest Two Years Ever Recorded (1.11C more than avg")

‘Climate Change Is Here’: Australia Experiences Hottest Two Years Ever Recorded (1.11C more than avg") | Climate & Clean Air Watch | Scoop.it
And there’s no sign that the heat wave is going to stop any time soon.

Using data from the Australian government’s Bureau of Meteorology, the Climate Council’s seasonal update — dubbed “Abnormal Autumn” — noted that average temperatures across Australia in April were 1.11°C above the long-term average, with average minimum temperatures 1.31°C above normal. Extreme high temperatures haven’t been confined to the summer months, either, the report said, noting September 2013 saw a mean temperature 2.75°C higher than the average, setting a new monthly record by more than a degree. Temperatures in October were also 1.43°C above average, priming conditions for an early and destructive bushfire season.

The exceptional heat has now continued into Australia’s current autumn, the report said, delaying the onset of winter conditions across the southern portion of the country.

“The climate system as a whole is heating up, and emissions of greenhouse gases, particularly from fossil fuels like coal, oil and gas, are the primary cause,” the report said. “Temperatures are projected to continue to increase, with more extremely hot days and fewer extremely cool days. A further increase in the number of extreme fire-weather days is expected in southern and eastern Australia, with a longer fire season in these regions.”

Bert Guevara's insight:

Warming goes on ... hitting new records.

"According to data compiled by Australia’s biggest crowd-funding campaign, the independent Climate Council, the period from May 2012 to April 2014 was the hottest 24-month period ever recorded in Australia. Next month, when the two-year period spans from June 2012 to May 2014, those above-average temperatures are expected to be even greater, the report said."

Onshore wind now cheapest energy source in Europe, says utility ("it's time to wean-off from fossils")

Onshore wind now cheapest energy source in Europe, says utility ("it's time to wean-off from fossils") | Climate & Clean Air Watch | Scoop.it
Onshore wind has become the cheapest form of energy in Europe according to a major continental utility, giving fossil fuels a run for their money. Despite the

A third of EDP’s energy is generated by wind and in a recent presentation to analysts by Joao Manso Neto, the firm’s head of renewables, figures showed that the levellised cost of electricity of onshore wind in Europe is 20 per cent cheaper than gas and one third cheaper than coal, assuming a 25 per cent wind capacity factor.

Neto told the analysts that wind energy is also cheaper than gas in key emerging markets such as Brazil, South Africa, Mexico, and major Asian markets, according to the Renewable Economywebsite.

He said: “It is clear, more and more, that our product (wind energy) is good, not just because it is green, but because it is cheaper.”

Yesterday, Lord Deben, chairman of the UK’s independent committee on climate change, said that there is enough onshore wind already in planning to meet the EU’s 2020 targets, echoing the comments of Britain’s Energy Minister, Michael Fallon, who said that onshore wind farms which had not been granted planning permission before next year’s general election would not be subsidised.

Bert Guevara's insight:

The downward trend of the price for renewable energy (especially on-shore wind) has made it very competitive vs. fossil fuels, according to the Europeans.

House Directs Pentagon To Ignore Climate Change ("because it is a political ideology ... aw c'mon!")

House Directs Pentagon To Ignore Climate Change ("because it is a political ideology ... aw c'mon!") | Climate & Clean Air Watch | Scoop.it
WASHINGTON -- The House passed an amendment to the National Defense Authorization bill on Thursday that would bar the Department of Defense from using funds to assess climate change and its implications for national security.

The amendment, from ...

None of the funds authorized to be appropriated or otherwise made available by this Act may be used to implement the U.S. Global Change Research Program National Climate Assessment, the Intergovernmental Panel on Climate Change's Fifth Assessment Report, the United Nation's Agenda 21 sustainable development plan, or the May 2013 Technical Update of the Social Cost of Carbon for Regulatory Impact Analysis Under Executive Order 12866.

"This amendment will prohibit the costs of the President's climate change policies being forced on the Department of Defense by the Obama Administration," wrote McKinley in a memo to House colleagues on Thursday that was obtained by The Huffington Post. "The climate is obviously changing; it has always been changing. With all the unrest around the [world], why should Congress divert funds from the mission of our military and national security to support a political ideology?"

Bert Guevara's insight:

Climate concerns have become mere political issues in the US. 

"... Nor is climate change a threat that the Obama administration dreamed up to distract the DOD. A National Intelligence Assessment issued during the George W. Bush administration concluded that climate change poses a significant threat to national security. And just this week, Tom Ridge, who served as homeland security secretary under Bush, said that climate change is "a real serious problem," one that "would bring destruction and economic damage" if we ignore it."

On days of severe pollution, Tianjin will halve the number of vehicles allowed on roads by restricting licence plate numbers, as well as halt construction and manufacturing activity, close schools for the day, and halt large-scale outdoor activities, the official Xinhua news agency said.

China has vowed to reverse the damage done to its environment by decades of untrammeled economic growth, and has identified the region of Beijing, Hebei and Tianjin as one of the key targets of a programme to curb big industries like steel, thermal power and cement, all major sources of smog.

About one third of the pollution in Beijing, whose often choking smog has been dubbed the "airpocalypse", comes from outside the city, a pollution watchdog said last month.


Bert Guevara's insight:

If this number-coding system for transport worked for France in reducing air pollution in a short time, then China is hoping it will work for them too.

In the Philippines, number-coding of vehicles is for traffic alleviation, but it can also be used for clean air campaigns.

Navy Demonstrates Fuel From Seawater Production ("another energy game changer from the US navy")

Navy Demonstrates Fuel From Seawater Production ("another energy game changer from the US navy") | Climate & Clean Air Watch | Scoop.it
EcoGeek - Technology for the Environment

A team of US Navy research scientists has developed a method to produce liquid fuel from seawater, using CO2 and hydrogen extracted from the ocean and then processed with a metal catalyst to produce liquid fuel. As a demonstration of the concept, an unmodified scale airplane has been flown with the seawater fuel.

The concentration of CO2 is about 140 times higher in seawater than it is in the atmosphere. Carbon dioxide and hydrogen are the two feedstocks needed to make hydrocarbons. The process relies on "an iron-based catalyst [which] has been developed that can achieve CO2 conversion levels up to 60 percent and decrease unwanted methane production in favor of longer-chain unsaturated hydrocarbons (olefins)." The process is claimed to be the first technology of this type with the potential for commercial implementation.

"The predicted cost of jet fuel using these technologies is in the range of $3-$6 per gallon, and with sufficient funding and partnerships, this approach could be commercially viable within the next seven to ten years."

Liquid fuel from seawater? Ask the US Navy.

"The predicted cost of jet fuel using these technologies is in the range of $3-$6 per gallon, and with sufficient funding and partnerships, this approach could be commercially viable within the next seven to ten years."

Supreme Court slaps down Big Coal ("cross border dirty air now illegal in US")

Supreme Court slaps down Big Coal ("cross border dirty air now illegal in US") | Climate & Clean Air Watch | Scoop.it
The ruling is a big win for the Obama administration, allowing it crack down on power plant pollution that blows across state borders.

In a major environmental victory for the Obama administration, the Supreme Court on Tuesday upheld the Environmental Protection Agency’s authority to regulate the smog-causing pollution from coal-fired power plants that wafts across state lines from 27 Midwestern and Appalachian states to the East Coast.

The 6-to-2 ruling upholds a centerpiece of what has become a signature of President Obama’s environmental agenda: a series of new Clean Air Act regulations aimed at cutting pollution from coal-fired power plants. Republicans and the coal industry have criticized the effort as a “war on coal.”

Sulfur dioxide and nitrogen oxide pollution from power plants can be carried long distances and the pollutants react with other substances to form smog and soot, which have been linked to respiratory illnesses and other disease. The cross-border pollution has prevented many cities and counties from complying with health-based air pollution standards set by law, because they have no authority to control it.

This recent US Supreme Court ruling makes it illegal to send polluted air to other territories -- a victory for Clean Air!!!

Can the Philippines take a cue?
