Global warming

Researchers have newly estimated how Earth's global mean surface temperature (GMST) will continue rising, albeit relatively briefly, even if all greenhouse gas emissions suddenly stop. The graph's thick dashed line represents the expected extra 0.2 degrees Celsius rise in GMST, followed by a sharp decline, indicating even more cooling with the cessation of all GHG emissions. Previous research focused only on carbon dioxide emissions (dotted line). The orange line reflects a rising GMST if emissions continue under a moderate business-as-usual scenario.

More global heating ‘baked in’ than previously thought, but so is more cooling, new research finds

Focusing only on reducing CO2 emissions misses the warming already baked into the system, as well as the extra cooling we’d enjoy if all emissions stop.

In a scene from the docuseries "Meltdown: Three Mile Island," CBS News anchor Walter Cronkite reports on the pending nuclear disaster in central Pennsylvania that came shockingly close to a "China syndrome" meltdown, and required a 14-year clean-up operation.

Is nuclear power safe enough to be part of our non-carbon future?

Tropical forests create year-round cooling, and collectively all forests keep Earth about 0.5 degrees Celsius cooler, according to new research.

Rising global temperatures could stabilize within 3- to 5-years if greenhouse gas emissions stopped now (dark blue line at 0.00 highlighted area above), contrary to decades of continued warming, which was previously believed.

New paradigm clarifies how global temperatures can stop rising within years, not decades

Five temperature records dating back to 1880 show how Earth's global mean surface temperature has risen and keeps rising. All show rapid warming in the past few decades, and all show the past decade has been the warmest.

Only a few degrees of global warming? So what.

A delicate balance of ocean currents transport heat around the planet and drive global weather patterns. But greenhouse gas emissions are slowing a key Atlantic Ocean current to the brink of collapse, with catastrophic global weather implications.

And now we’re changing ocean currents — threatening to disrupt and worsen global weather
