Tyndal Climate Conference

Today, in 2013, we face an unavoidably radical future. We either continue with rising emissions and reap the radical repercussions of severe climate change, or we acknowledge that we have a choice and pursue radical emission reductions: No longer is there a non-radical option. Moreover, low-carbon supply technologies cannot deliver the necessary rate of emission reductions -- they need to be complemented with rapid, deep and early reductions in energy consumption -- the rationale for this conference.

Rise and Fall of the Westerlies

Two circular bands of winds called the westerlies are being changed by human-caused global warming. The consequences from these changes could become quite large and come on suddenly - quite the surprise for anyone who still thinks climate change is a future "slow" problem. In the words of Paul Mayewski, director of the University of Maine's Climate Change Institute, these and associated climate changes are “just not part of a natural cycle.” From his perspective, an abrupt climate change has also just taken place - in the Arctic.

A new paper explores how policy makers can work with the uncomfortable knowledge that the prospects for holding average global warming to below two degrees Celsius are rapidly decreasing. They identify for the first time key uncertainties, risks and opportunities associated with alternatives to the two degree target of international climate policy, published in the peer-reviewed journal Climate Policy.

Warmest Arctic

It’s been a hot week for global warming. NASA released global temperature data showing that this September tied with 2005 for the warmest September on record. That’s doubly impressive since 2005 was warmed by an El Niño and accompanying warm Pacific ocean temperatures, whereas 2013 has had cooler Pacific temperatures all year. Greenhouse gases keep warming the planet to unprecedented levels with unprecedented speed. That’s the conclusion of two new studies out this week.

Plenty of studies have shown that the Arctic is warming and that the ice caps are melting, but how does it compare to the past, and how serious is it?

New research shows that average summer temperatures in the Canadian Arctic over the last century are the highest in the last 44,000 years, and perhaps the highest in 120,000 years...more

The aims of international climate negotiations and of the global climate action movement are to "prevent" dangerous climate change. But what do we do if global warming is already dangerous? In a concluding section, this report argues that with clear evidence that climate change is already dangerous, we are in an emergency and face "...an unavoidably radical future".
