Union of Concerned Scientists Experts Available to Talk about New IPCC Report

Report to be Released Sunday, October 7 at 9 p.m. ET


The United Nations' Intergovernmental Panel on Climate Change (IPCC) will release a report Sunday on what it would take to limit global warming to 1.5 degrees Celsius, or 2.7 degrees Fahrenheit, above pre-industrial levels--the target established in the 2015 Paris climate agreement. The report will also analyze the impacts that would occur at 1.5 degrees Celsius and 2 degrees Celsius, or 3.6 degrees Fahrenheit.

Experts at the Union of Concerned Scientists (UCS) have posted blogs to give reporters a jump-start in their reporting on the IPCC report.

  • Astrid Caldas, senior climate scientist, wrote about how extreme precipitation will likely change if global temperatures increase 1.5 degrees or 2 degrees Celsius.
  • Rachel Cleetus, policy director with the Climate and Energy Program and lead economist, wrote about seven key takeaways related to the IPCC report and its policy implications.
  • Rachel Licker, senior climate scientist, wrote about extreme heat and the different impacts that will likely occur at 1.5 degrees and 2 degrees Celsius.
  • Alden Meyer, director of strategy and policy, wrote about how the report will help drive policy and political deliberations over the next two years on the need to raise climate ambition, including at December's climate summit in Poland (COP24).
  • Brenda Ekwurzel, director of climate science and senior scientist, wrote about the "carbon budget," or how much carbon dioxide can be released to meet the Paris climate agreement goal. (Note: Brenda's blog will go live around 1:30 p.m. ET today, all other blogs are live now.)

If you would like to speak with any of these experts, including after the IPCC report has been released, please contact UCS Communications Officer Ashley Siefert Nunes via email at or by phone at +1 202-331-5666 (work) or +1 952-239-0199 (cell).

See the entire blog series here. After the report has been released, UCS experts will post additional blogs, including those that summarize the major scientific takeaways from the report, differences in sea level rise that will likely occur at 1.5 degrees and 2 degrees Celsius, and how different temperature increases will affect biodiversity and conservation.

IMPORTANT: For members of the media to receive an embargoed copy of the final report, they must register with the IPCC. Embargoed copies are expected to be available on October 6 or 7 (Korean Standard Time), depending on when the plenary concludes.
