New Study Says World Must Cut Short-Lived Climate Pollutants as Well as Carbon Dioxide to Meet Paris Agreement Goals

Inside Climate News

The study found that limiting warming in coming decades as well as longer term requires policies that focus not only on reducing emissions of carbon dioxide, but also of “short-lived climate pollutants”—greenhouse gases including methane and hydrofluorocarbons (HFCs)—along with black carbon, or soot.

Recent developments on carbon dioxide removal: Increasing policy support but governance issues remain

Law Columbia

Support for carbon dioxide removal (CDR) is growing globally. The recent boost for CDR is linked to an emerging trend in climate policy which understands CDR as supplemental to urgent action on decarbonization and overall greenhouse gas (GHG) emission reductions (rather than a replacement for those activities). concrete).

What EXACTLY Did the UN Conference Decide?

Legal Planet

This group of nearly all the world’s nations says that it: [R]ecognizes the need for deep, rapid and sustained reductions in greenhouse gas emissions in line with 1.5 °C Coal is supposed to be “phased down” except where the resulting carbon dioxide is removed and securely stored (which may or may not actually be feasible).

Progress Possible at COP 28 Despite Fossil Fuel Industry Deception

Union of Concerned Scientists

Success at COP28 is likely to be measured by the inclusion of strong fossil fuel phaseout language, free from loopholes, in the final agreement. Global net anthropogenic greenhouse gas emissions 1990–2019. By 2019, the largest growth in absolute emissions occurred in carbon dioxide from fossil fuels and industry.

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). Article 4, section 1.

Carbon capture nets 2 billion tonnes of CO2 each year — but it’s not enough

Environmental News Bits

More than 2 billion tonnes of carbon dioxide is being removed from Earth’s atmosphere each year, according to an analysis of global efforts to capture and store the greenhouse gas. Read the full story in Nature.

Future Trends in Climate Litigation Against Governments

Law Columbia

Here, we define the Ambition Gap as the difference between the emissions reductions expected from a government’s planned policies and pledges, and those required to meet the long-term temperature goals of the Paris Agreement, in light of best available science. C temperature target within reach.
