COP 19 conference: a key step in the fight against climate change

COP 19 conference: a key step in the fight against climate change | Développement durable et efficacité énergétique | Scoop.it

Sea levels and air temperatures continue to rise according to studies, which is expected to lead to more floods and worse heat waves. To help prevent this, the 19th UN Climate Conference takes place this month to discuss how to curb carbon emissions after 2020, including key steps towards a new globally binding agreement by 2015. Check out the infographic on climate change for more information.

In the Climate Change Economy, It's About Efficiency, Not Just Growth

In the Climate Change Economy, It's About Efficiency, Not Just Growth | Développement durable et efficacité énergétique | Scoop.it

North American cities are producing substantially less wealth per ton of greenhouse gas emissions than their European counterparts.


Research has shown that if you know a country's GDP, you can pretty accurately estimate its carbon emissions. There's "almost a mechanical relationship" between the two. And as a depressing corollary: Emissions rise much faster in good times than they fall during, say, a global recession.

Cities in some parts of the world are already doing a substantially better job at decoupling these two trends than others, wringing the most wealth out of the smallest carbon footprint. These are the cities that produce the greatest amount of GDP per ton of greenhouse gasses emitted.


The Carbon Disclosure Project, along with AECOM and the C40 Cities, have calculated this "economic efficiency" for dozens of global cities that participated in a questionnaire on how they are preparing for climate change...

The Happiest Cities in the World [Infographic]

The Happiest Cities in the World [Infographic] | Développement durable et efficacité énergétique | Scoop.it

Happiness is a fleeting commodity in reality, it comes and goes, but the perception of happiness is the real bottom-line driver for cities and their branding.


What makes urban dwellers happy? According to a 10,000 respondent, 20 country research effort from GfK Custom Research, it is a location-based perception: does your city offer you places to go that make you happy? Apparently, the perception-reality gap is what is really interesting the city governments. Happiness is a fleeting commodity in reality, it comes and goes, but the perception of happiness is the real bottom-line driver for cities and their branding.

The winning locations end up being quite obvious candidates; entertainment and cultural heavyweights, beautiful urban areas and laid-back lifestyles lead the march...

Climate Change and Human Responsibility

Climate Change and Human Responsibility | Développement durable et efficacité énergétique | Scoop.it
It can’t be denied any longer: Sea levels are rising, major droughts are continuing, and record hot summers are being experienced all around the world. Climate change is real and, as residents of Earth, we have a responsibility to our planet to do something about it. A recent study conducted by Yale University and George Mason University finds that, for the first time since the research began in 2008, the majority of Americans believe that global warming is mostly a man-made phenomenon.

As sobering images of catastrophes are making headlines, this graphic looks at how people are recognizing that the effects of their actions aren’t just an increasing danger to the world but are a direct threat to the future for themselves and their families.

Cities: Drivers of Sustainable Human Development & Prosperity

Cities: Drivers of Sustainable Human Development & Prosperity | Développement durable et efficacité énergétique | Scoop.it
As we plan for the future of our planet, it is imperative that we consider the effects of development on both the environment and human populations. A city is only truly sustainable if it uses natural resources efficiently while still fully meeting the needs of its inhabitants and a decent standard of living.

Recently, the UN Human Settlements Program (UN-HABITAT) launched its “State of the World’s Cities Report 2012/2013” which addresses the prosperity of cities. According to the report, the first step to achieving prosperity is to define the goal: What does prosperity mean in 2012? This is a difficult question to answer given the vast disparity of living conditions throughout the world. Additionally, it is imperative that the definition of prosperity today consider the needs of future generations. To this end, UN-Habitat developed a “City Prosperity Index,” which translates the five dimensions of prosperity identified by UN-Habitiat—productivity, infrastructure development, quality of life, equity and social inclusion, environmental sustainability—into measurable indicators (see page 15 of the report).


This definition of the prosperous city is consistent with the principles of a smart, sustainable and just city... further reading at the article link

Global Warming: a new report on loss of life and global economic damage

Global Warming: a new report on loss of life and global economic damage | Développement durable et efficacité énergétique | Scoop.it

From devastating floods in China and the Philippines to droughts in Africa, the extreme weather patterns that hit the United States have impacted sites around the world as the face of global warming.

According to a new report, climate change has already contributed to 400,000 deaths per year and over $699 billion, 0.9 percent annually, in loss to gross domestic product (GDP). The report estimates even greater damage from air pollution caused by the burning of fossil fuels. also driving global warming.

'Climate Vulnerability Monitor: A Guide to the Cold Calculus of a Hot Planet (2nd Edition)' was written by over 50 scientists, economists and policy experts, and commissioned by 20 governments. The study calculates and compares the vulnerability of 184 countries in terms of environmental disasters, habitat change, health impact and industry stress.

Read on for statistics, implications and global health issues related to these new findings, proving that 'failing to deal with global warming will have real and lasting impacts on local communities, economies, health and safety, and people around the world.'

More Than 800,000 Scientific Papers In One Beautiful Infographic

More Than 800,000 Scientific Papers In One Beautiful Infographic | Développement durable et efficacité énergétique | Scoop.it

ArXiv is an online archive that stores hundreds of thousands of scientific papers in physics, mathematics, and other fields. The citations in those papers link to one another, forming a web, but you're not going to see those connections just by sifting through the archive.

So physicist Damien George and Ph.D student Rob Knegjens took it on themselves to create Paperscape, an interactive infographic that beautifully and intuitively charts the papers.

The infographic is a mass of circles. Each circle represents a paper, and the bigger a circle is, the more highly cited it is. The papers are color-coded by discipline--pink for astrophysics, yellow for math, etc.--and papers that share many of the same citations are placed closer together.

This is cool!  It is like the map of the Internet done last year sometime.

I lucked out and found the section about SNA in the lower left hand side of the map.  Look for Network under the Quantitative Finance section, go figure.

11,000 Years' Worth of Climate Data

11,000 Years' Worth of Climate Data | Développement durable et efficacité énergétique | Scoop.it

New research takes the deepest dive ever into historic climate records.

 

Back in 1999 Penn State climate scientist Michael Mann released the climate change movement's most potent symbol: The "hockey stick," a line graph of global temperature over the last 1,500 years that shows an unmistakable, massive uptick in the twentieth century when humans began to dump large amounts of greenhouse gases into the atmosphere. It's among the most compelling bits of proof out there that human beings are behind global warming, and as such has become a target on Mann's back for climate denialists looking to draw a bead on scientists.

 

Now it's gotten a makeover: A study published in Science reconstructs global temperatures further back than ever before -- a full 11,300 years. The new analysis finds that the only problem with Mann's hockey stick was that its handle was about 9,000 years too short...

Heat from North American cities causing warmer winters, study finds

Heat from North American cities causing warmer winters, study finds | Développement durable et efficacité énergétique | Scoop.it

Researchers say extra heat generated by huge cities explains additional warming not explained by existing climate models.


Those who wonder why large parts of North America seem to be skipping winter have a new answer in addition to climate change: big city life.

A study, published in the journal Nature Climate Change, found that the heat thrown off by major metropolitan areas on America's east coast caused winter warming across large areas of North America, thousands of miles away from those cities.

 

Scientists have for years been trying to untangle how big cities – with the sprawl of buildings and cars – affect climate. The study suggests cities themselves have far-reaching effects on climate, in addition to the climate pollution caused by the burning of fossil fuels.

Very interesting reading this. It seems quite true since the past winter didn't seem as cold as most winters here in Rhode Island. If the big cities cause the winter to be less cool then in the future, would winter even be cold? Lets hope and say this problem will never happen.

An Infographic Breakdown Of The World's Greenest Cities

An Infographic Breakdown Of The World's Greenest Cities | Développement durable et efficacité énergétique | Scoop.it

This infographic focuses on the cities of London, New York, Vancouver, Copenhagen, Amsterdam, and Stockholm.


It’s hard to quantify what makes a city "greener" than any other metropolis, but there are some clues: car ownership, green space, bicycle usage, solar installations, recycling, and water consumption are just a few factors that create environmentally responsible cities.

An infographic from HouseTrip lays out what different cities are doing in an easy-to-read format. A handful of major world cities stand out as leaders. This infographic focuses on London, New York, Vancouver, Copenhagen, Amsterdam, and Stockholm; three of these cities made it into our top 10 smart cities list (two others were runners-up). Each of these cities have statistics worth mentioning. Amsterdam has one bike for every 0.73 people, Copenhagen has legislation requiring all new buildings to have green roofs (this will add 5,000 square meters of vegetation), and only 44% of New Yorkers own a car, compared to 95% of Americans overall.
