Why We Need CCS, Part 4: Carbon Negative Solutions

June 30, 2014 by Schalk Cloete

CCS and Carbon Negative Solutions

If climate science proves to be correct and the 450 ppm scenario is confirmed as a global priority in the medium-term future, we will probably require a very large scale deployment of CO2 negative technologies from the middle of this century. According to the IPCC, CCS will play a very important role in this regard.[read more]

Are the Semantics of Climate Change Assessments Fooling Us?

June 12, 2014 by Jessica Kennedy

The 1990 IPCC report contains warnings about effects of climate change in its “Summary for Policymakers” (which is great, because how many policymakers read the whole report?), but when the document is read more thoroughly, the language weakens the urgency for climate change action.[read more]

June 9, 2014 by Matthew Stepp

Climate Action and Inaction

What are the future impacts of a changing climate system? Extreme weather? Higher sea level? More drought and heat waves? Where will these impacts be felt the most? Answering these questions depends on a simple factor: the quantity of carbon emissions emitted in the coming decades.[read more]

Climate Risk and the Future

 

The German economist Ottmar Edenhofer, who co-chaired the IPCC committee that wrote the most recent UN report, commented in the New York Times: “We cannot afford to lose another decade.” If we do it becomes extremely costly to achieve climate stabilization.[read more]

Understanding the IPCC: An Important Follow-Up

May 6, 2014 by Robert Stavins

A week ago, I wrote a blog about my frustrations with the approval process of one part of the Summary for Policymakers of the recent IPCC Report. Some in the more fringe elements of the press and blogosphere quickly capitalized on the situation by distorting the message of my original post.[read more]

A recent report by the world’s leading scientists has concluded that immediate action is needed globally if we are to avoid the worst impacts of climate change. But with a global agreement on climate change not expected until 2015, we can’t afford to wait. We need to act now, agree later.[read more]

10 Charts that Explain Climate Change Mitigation (Plus 2 More that Explain Negotiation)

Climate Change Mitigation and Negotiation

I really love the IPCC (high confidence), but if you read the summary for policymakers (medium confidence), some of the wording doesn’t exactly role of the tongue (robust evidence, medium agreement). You know what I mean? (medium evidence, medium agreement).[read more]

Fossil Fuel Makes Stuff

The IPCC has just recently released its third assessment report on mitigating climate change. I have spent the morning reading the full summary, and to help you save a little time I have whittled it down to a six word summary: Fossils fuels are for making stuff.[read more]
