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

Union of Concerned Scientists

Grade F: First major vital sign shift in its report card Different factors are at play in terms of whether the Arctic is a net sink or source of carbon. On one hand, warming temperatures increased vegetation in the region with increased uptake of carbon dioxide. The urgency for reducing emissions is a serious Arctic warning.

Net Zero/Not Zero

Real Climate

With empirical data and more and better modeling, it has become clear that, to first approximation, the eventual anthropogenic warming from carbon dioxide is tied to the cumulative emissions. This figure is from the AR6 SPM: The relationship between cumulative carbon emissions and temperature (SPM AR6).

Don’t hamstring carbon removal

Legal Planet

Assessments by the IPCC have made clear that the most feasible way for the world to meet its target of restricting climate change to below two degrees Celsius of warming includes rapid and massive expansion of carbon removal technology – technology that would extract carbon dioxide and permanently sequester that carbon dioxide underground.

Whales and Lobstermen Have a Common Enemy

Union of Concerned Scientists

A simple statement that masks just how complicated the issues are: mixing politics, economics, livelihoods, fisheries and endangered species in the ocean body that is the Gulf of Maine. He was on to something And the lobsterman was correct: we can blame carbon emissions for ocean acidification and warming in the Gulf of Maine.

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

Union of Concerned Scientists

The longevity of naturally occurring carbon sinks, like those in Earth’s forests, is a key part of all modeled and projected pathways to net-zero. 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.

Arctic Futures: White Shield or Blue Economy

Legal Planet

Multiplying proposals Last month the ‘Ocean Visions’ coalition of research institutions released an Arctic Sea Ice Road Map. The company sees this as a way to prevent “a blue ocean event in which Arctic sea ice disappears entirely … a tipping point with catastrophic global consequences.” Where do we go from here?

As Wildfire Season Approaches, Phytoplankton Take On Fires’ Trickiest Emissions

Inside Climate News

Microbial marine life can thrive off the black carbon released from wildfires and bolster the oceanic carbon sink. billion metric tons of carbon dioxide emissions around the globe. Scientists still emphasize their sequestration role has its limits. By Jenaye Johnson Just last year wildfires generated over 2.1
