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.

Mexico y el Cambio Climático

Legal Planet

Mexico’s carbon emissions are about the same as those of Texas, the highest-emitting US state. Per capita emissions, however, are far lower, given Mexico’s much larger population. Unfortunately, there are doubts about how much progress Mexico will make in cutting emissions.

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).

Investors Need to Know the Full Scope of Corporate Carbon Emissions

Union of Concerned Scientists

They’re called Scope 3 emissions, and they are key to understanding the big picture of a company’s impact on the environment. First, let me explain the three “scopes” of carbon emissions. Scope 1 emissions come from power plants, oil rigs and other sources directly owned or controlled by a company.

Summer Heat Is Coming: Will New Policies Protect Workers?

Union of Concerned Scientists

According to the National Oceanic and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA), 2021 followed the distressing trend of excessive heat, as the sixth hottest year on record (a tie with 2018). Photo is author’s own. Last year brought the dangers of extreme heat to the forefront.

IMO Fails Duty to Protect Climate and the Arctic

Ocean Conservancy

Thanks for signing up for Ocean Conservancy emails. No less galling than the inaction on HFO and scrubbers were the decisions on short-term GHG emissions—though a shift in the winds may be coming at last. The easiest is to slow the vessel down, reducing both fuel consumption and carbon emissions. Stay connected.
