The Copenhagen Diagnosis: Climate Science Report

If you want to know the latest climate change science, a new report has been released by The University of New South Wales Climate Change Research Centre (CCRC) called:

The Copenhagen Diagnosis: Updating the World on the Latest Climate Science.

Also worth checking out is the website http://copenhagendiagnosis.org/ which has more information about the authors and the research itself including a great summary. Here is some of the blurb on the report from the website:

"It is more than three years since the drafting of text was completed for the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4). In the meantime, many hundreds of papers have been published on a suite of topics related to human-induced climate change.

The purpose of this report is to synthesize the most policy-relevant climate science published since the close-off of material for the last IPCC report. The rationale is two-fold.

First, this report serves as an interim evaluation of the evolving science midway through an IPCC cycle - IPCC AR5 is not due for completion until 2013.

Second, and most important, the report serves as a handbook of science updates that supplements the IPCC AR4 in time for Copenhagen in December 2009, and any national or international climate change policy negotiations that follow."

"The report has been purposefully written with a target readership of policy-makers, stakeholders, the media and the broader public. Each section begins with a set of key points that summarises the main findings. The science contained in the report is based on the most credible and significant peer-reviewed literature available at the time of publication. The authors primarily comprise previous IPCC lead authors familiar with the rigor and completeness required for a scientific assessment of this nature."

The main finding include:
  • Surging greenhouse gas emissions
  • Recent global temperatures demonstrate human-based warming
  • Acceleration of melting of ice sheets, glaciers and ice-caps
  • Rapid Artic sea-ice decline
  • Current sea-level rise underestimates
  • Sea-level prediction revised
  • Delay in action risks irreversible damage
  • The turning point must come soon
