Arctic Report Card 2024: How Did the Region Fare? Ask the Caribou

Union of Concerned Scientists

For the first time, the Arctic Report Card assessed that the Arctic is faltering as a reliable area for storing carbon away from the atmosphere ( Natalie et al., It was its first failing grade after thousands of years holding onto more carbon than released to the atmosphere. in Arc2024 ). Methane releases were sustained as well.

Detroit Flooding Previews Risks from a Warming Climate

Circle of Blue

The Detroit cloudburst was the result of a nasty weather combination—a cold front sweeping across the Midwest, plus a mass of humidity hanging over the city—which promises to be all the more powerful as the climate continues to warm. Similarly, the annual number of extreme storms in southern Michigan doubled between 1964 and 2013.

From Research to Action: The Growing Impact of Attribution Science

Union of Concerned Scientists

Attribution science , which is about understanding the role of climate change versus natural weather patterns and climate variability, can help us better understand the connections between extreme weather and climate change, provide new insight into what specific emissions are driving the worst impacts, and help shape climate solutions.

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

I followed with great interest the launch of the sixth assessment report Working Group 1 (The Physical Science Basis) from the Intergovernmental Panel on Climate Change (IPCC) on August 9th. The problems with the SPM are similar those from the previous fifth assessment report which prompted me to write a post in 2013.

Upcoming Developments in International Governance of Marine Carbon Dioxide Removal

Law Columbia

The Intergovernmental Panel on Climate Change has concluded that CDR will be needed, alongside deep emissions cuts, to limit global warming to 1.5 But, in 2013, the parties to the London Protocol adopted an amendment that is intended to be. The 2013 amendment has not yet entered into force.

What’s the Role of the Land Carbon Sink in Achieving US Climate Goals?

Union of Concerned Scientists

Without the considerable carbon absorption capacity of our lands (and oceans), we’d currently have much more CO 2 in the atmosphere and an accelerated timeline of warming. In North America, the land carbon sink between 2004 and 2013 offset roughly 39% of fossil fuel emissions , but varied substantially year to year.

A deep dive into the IPCC’s updated carbon budget numbers

Real Climate

And since the first IPCC estimates published in 2013, we have learned a lot and have gotten much better at estimating remaining carbon budgets. How have these estimates changed since previous reports? IPCC reported carbon budgets for the first time in 2013. in 2018, but they represent a significant update since AR5 in 2013.
