Half a Degree of Warming Could be the Difference Between Survival and Extinction for Many Species

, deputy director, Climate & Energy Program

As a conservationist who has been ringing the alarm bells on climate change threats to biodiversity for more than 25 years, I hardly know where to start in responding to the findings of the newest, and most alarming, Intergovernmental Panel on Climate Change (IPCC) Special Report on the impacts of a 1.5°Celsius global warming.  I’m not surprised that the IPPC delivers more bad news after reviewing more than 6,000 recent scientific reports, but I am surprised by just how bad the news is.

Seven Things You Should Know About the IPCC 1.5°C Special Report and its Policy Implications

, Policy Director and Lead Economist, Climate & Energy

The Intergovernmental Panel on Climate Change (IPCC) is soon going to release an important report to help inform global efforts to limit climate change. The special report details the impacts of a global average temperature increase of 1.5°C relative to 2°C above pre-industrial levels, and pathways to limit temperature increase to that level. Governments of the world have come together this week in Incheon, South Korea to negotiate and agree on the report’s Summary for Policymakers, which is based on the underlying science in the final IPCC report. The summary is expected to be released on Monday morning in South Korea (late on Sunday night here on the US east coast).

Understanding 1.5°C: The IPCC’s Forthcoming Special Report

, senior climate scientist

The Intergovernmental Panel on Climate Change (IPCC) – an international body that develops non-policy prescriptive climate science assessments for decisionmakers – is currently compiling a Special Report that will provide information on what it would take to limit global warming to 1.5 degrees Celsius above pre-industrial levels. The report will also assess the climate impacts that could be avoided by keeping warming to this level, and the ways we can limit the worst impacts of climate change and adapt to the ones that are unavoidable.

Renewable Energy Surges Globally with China and India in the Lead

, Policy Director and Lead Economist, Climate & Energy

If the Trump administration’s anti-climate shenanigans have you down, maybe it’s time to take a break for some good news: the incredible progress on renewable energy in the US and world-wide. Clean energy momentum in US states and cities, as well as businesses support, is building rapidly. This blogpost is about the latest global developments—focusing on China and India, two large and growing economies that many experts think will play a decisive role in the future of global carbon emissions.
