Inside Climate News: New Research Increases Urgency to For COP28 Action

Nov 17 – Research released this week raises new questions about how much more Earth may warm, or cool, if and when human carbon dioxide emissions zero out. Best estimates to date suggest that the global surface temperature would stabilize within a few decades, but the new paper in the journal Frontiers in Science examines the uncertainties around that conclusion, including how the planet’s key carbon dioxide-absorbing systems, like forests and oceans, will respond. “There is a non-negligible chance that global warming will continue after net zero and intensify dangerous climate change,” he said. Without immediate emissions cuts, global temperatures will breach the Paris Agreement’s goals sooner than expected, scientists say. Read ON.

CNN: The planet is heating up faster than predicted, says scientist who sounded climate alarm in the 1980s

Nov 2 – “The planet is on track to heat up at a much faster rate than scientists have previously predicted, meaning a key global warming threshold could be breached this decade, according to a new study co-authored by James Hansen — the US scientist widely credited with being the first to publicly sound the alarm on the climate crisis in the 1980s. In the paper, published in the journal Oxford Open Climate Change, Hansen and more than a dozen other scientists used a combination of paleoclimate data, including data from polar ice cores and tree rings, climate models and observational data, to conclude that the Earth is much more sensitive to climate change than previously understood. “We are in the early phase of a climate emergency,” according to the report, which warns a surge of heat “already in the pipeline” will rapidly push global temperatures beyond what has been predicted, resulting in warming that exceeds 1.5 degrees Celsius above pre-industrial levels in the 2020s, and above 2 degrees Celsius before 2050.” Deeper READ.
