Why Im optimistic on climate change despite the impossible goals of the Paris talks

Washington Post: Only a few days into the UN climate summit, and it is already time to sing the Paris blues. The path to Paris was, unfortunately, paved with pessimism and imperfect accords: Rio, Kyoto, Copenhagen. In the meantime, carbon dioxide in the air has increased, raising the worlds average temperature by one degree Celsius relative to pre-industrial times. Looking ahead, the forecast calls for overcast skies. A Paris climate deal is already framed by an impossible goal: a maximum of 2 degrees Celsius,...
Religious leaders step up pressure for action on climate change

Guardian: Two years ago Yeb Sano, the Filipino governments lead climate negotiator, broke down in tears in front of the worlds diplomats in Warsaw as typhoon Haiyan ripped through his home city of Tacloban, killing thousands of people. This week he arrived at the Paris climate talks a changed man. No longer a star diplomat, he came on foot after completing a 58-day, 1,500km pilgrimage from Rome. He is now an official adviser to the archbishop of Manila. The politics of climate change are limiting,...

Paris climate talks: what difference will temperature rises really make?

Guardian: Without action, climate scientists have warned that temperatures could rise by nearly 5C above pre-industrial levels by 2100. World leaders meeting in Paris hope to keep average global surface temperature rises below 2C but their pledges to cut emissions could still see up to 3C according to analyses. While it is very hard to make firm predictions, here are some of the potential impacts. All are for possible temperature rises occurring by 2100. 1C 2015 was the first year to reach this level...

Though climate change is a crisis, the population threat is even worse
2015-12-04 07:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: The perennial cry: we need to talk about climate change. And this week, with world leaders in Paris, we have been. But only up to a point. For the likely impact of the rising global population is almost entirely absent, not only from the debate about climate change, but also from that about loss of biological diversity, food and water security, disease, pollution and energy. Lets just remind ourselves of the population statistics of the past half century. In just over half my lifetime, the worlds...

Trapping climate pollutant methane gas in porous carbon
2015-12-04 02:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: As talks of global warming are once again making headlines, scientists have renewed their efforts to understand how to best limit its effects. For example, sequestrating short-lived climate pollutants, such as methane and black carbon, yields much faster reductions in global warming compared to reductions in CO2. To do so, it is essential to have a better grasp of the nature of physico-chemical properties of gases interacting with porous carbon. Now, a team of chemical engineering researchers based...
