Uruguay makes dramatic shift to nearly 95% electricity from clean energy | Jonathan Watts | The Guardian

Uruguay makes dramatic shift to nearly 95% electricity from clean energy | Jonathan Watts | The Guardian | Banco de Aulas | Scoop.it

As the world gathers in Paris for the daunting task of switching from fossil fuels to renewable energy, one small country on the other side of the Atlantic is making that transition look childishly simple and affordable.

In less than 10 years, Uruguay has slashed its carbon footprint without government subsidies or higher consumer costs, according to the country’s head of climate change policy, Ramón Méndez.

In fact, he says that now that renewables provide 94.5% of the country’s electricity, prices are lower than in the past relative to inflation. There are also fewer power cuts because a diverse energy mix means greater resilience to droughts.

It was a very different story just 15 years ago. Back at the turn of the century oil accounted for 27% of Uruguay’s imports and a new pipeline was just about to begin supplying gas from Argentina.

Oslo moves to ban cars from city centre within four years | AFP | The Guardian

Oslo moves to ban cars from city centre within four years | AFP | The Guardian | Banco de Aulas | Scoop.it

Oslo’s new leftist city government said Monday it wants to ban private cars from the city centre by 2019 as part of a plan to slash greenhouse gas emissions.

The Labour Party and its allies the Socialist Left and the Green Party, winners of the 14 September municipal elections in the Norwegian capital, presented a platform focused on the environment and the fight against climate change.

The programme envisages a ban on private vehicles in the city centre which, according to the Verdans Gang newspaper, is home to only about 1,000 people but where some 90,000 work.

The new city government did not give details of how the plan would be implemented.

But the proposal has sparked concerns among local businessmen, who noted that 11 of the city’s 57 shopping centres are in the planned car-free zone.

Stop burning fossil fuels now: there is no CO2 'technofix', scientists warn | Tim Radford | The Guardian

Stop burning fossil fuels now: there is no CO2 'technofix', scientists warn | Tim Radford | The Guardian | Banco de Aulas | Scoop.it

German researchers have demonstrated once again that the best way to limit climate change is to stop burning fossil fuels now.

In a “thought experiment” they tried another option: the future dramatic removal of huge volumes of carbon dioxide from the atmosphere. This would, they concluded, return the atmosphere to the greenhouse gas concentrations that existed for most of human history – but it wouldn’t save the oceans.

That is, the oceans would stay warmer, and more acidic, for thousands of years, and the consequences for marine life could be catastrophic.

The research, published in Nature Climate Change today delivers yet another demonstration that there is so far no feasible “technofix” that would allow humans to go on mining and drilling for coal, oil and gas (known as the “business as usual” scenario), and then geoengineer a solution when climate change becomes calamitous.

Adam Deneault's curator insight, December 14, 2015 5:53 PM

The great green wall initiative project, is a project which wants to plant tens of thousands of trees, roughly fifty thousand trees alone in Senegal. The point of this is to restore a failing  environment. Around five hundred million people are living in a desertification area. Both human and nature is at fault for this creation of a transition zone getting bigger and bigger, Humans are not necessarily taking care of the land like it should be taken care of and as for factors of nature such as climate change, drought and not enough rain. There are social impacts that may affect the area too, experts think that improvements in land and economy may help curb terrorism in Mali. 

Matt Ramsdell's curator insight, December 14, 2015 11:59 PM

The great green wall is a way of separating the desert from the rain forest in Africa The Sahel is the area that separates the deforestation and the desert and would be a way to keep the desert in a different climatic region of the country.

Martin Kemp's curator insight, December 17, 2015 2:40 PM

this a great i think, the only way that countries in an area with such harsh environments can survive is by helping eachother and using their own beneficial land to help other and recieve help for their own deficiencies.

Climate Change Video Guide | Banco de Aulas | Scoop.it
An in-depth, multimedia look at climate change, its global impact, and efforts to combat it.

 

This guide on climate change from the Council on Foreign Relations (independent think tank) covers many of the geopolitical, economic and environmental issues that confront the Earth as global temperatures rise.  Rather than produce a full length feature film, they have organized the this as an interactive video, allowing the user to get short (a couple of minutes) answer to specific questions about the science, foreign policy or economic ramifications of adapting to climate change.

Chemicals That Make Plants Defend Themselves Could Replace Pesticides - Elsevier (2015)

Chemical triggers that make plants defend themselves against insects could replace pesticides, causing less damage to the environment. New research... identifies five chemicals that trigger rice plants to fend off a common pest – the white-backed planthopper, Sogatella furcifera

 

Pesticides are used around the world to control insects that destroy crops... One of the problems with many pesticides is that they kill indiscriminately. For rice plants, this means pesticides kill the natural enemies of one of their biggest pests, the white-backed planthopper... This pest... causes the plants to wilt and can damage the grains. It also transmits a virus disease... which stunts the plants’ growth and stops them from “heading,” which is when pollination occurs.

 

Left untreated, many of the insects’ eggs would be eaten, but when pesticides are used these hatch, leading to even more insects on the plants. What’s more, in some areas as many as a third of the planthoppers are resistant to pesticides... “Therefore, developing safe and effective methods to control insect pests is highly desired”... 

 

Because of the problems of using pesticides, it’s vital to find new solutions to help protect rice plants from infestation. Plants have natural self-defense mechanisms that kick in when they are infested with pests like the planthopper. This defense mechanism can be switched on using chemicals that do not harm the environment and are not toxic to the insects or their natural enemies... 

 

Researchers... developed a new way of identifying these chemicals. Using a specially designed screening system, they determined to what extent different chemicals switched on the plants’ defense mechanism... The researchers used bioassays to show that these chemicals could trigger the plant defense mechanism and repel the white-backed planthopper. This suggests that these chemicals have the potential to be used in insect pest management... 

 

“This new approach to pest management could help protect the ecosystem while defending important crops against attack.”

The next step for the research will be to explore how effective the chemicals are at boosting the plants’ defenses and controlling planthoppers in the field.

Its good to see more research in these areas - but it would be good if in parallel we looked at potential impact of activated and elevated triggers and response  in terms of ecosystems and human health.  Multi-systemic approaches are going to be increasingly needed, which is worrying given how limited funding in this area already is..

If you are looking for a visual that looks at the new rules surrounding carbon emission and at what each state may have to do and how others are perceiving the new regulations you should check out this visual. You may scroll down the page (first click through to the site) or you can view it as a slideshow.

This visual would be great to share with students as it is designed as a cartoon (with many panels). It is easy to understand and describes where carbon emissions come from (in the US) as well as the impact this may have on countries outside the US.
