Earth’s protective ozone layer is slowly but noticeably healing at a pace that would fully mend the hole over Antarctica in about 43 years, a new United Nations report says.

Starting in the 1970s, scientists working for the oil giant made remarkably accurate projections of just how much burning fossil fuels would warm the planet.

‘The fact that we’re seeing such clear increases in ocean heat content, extending over decades now, shows that there is a significant change underway,’ one longtime researcher says.

When I joined CCL in 2017, I went to the DC conference and learned about the carbon budget — the amount of GHGs that the IPCC said we could add to the atmosphere and still…

Deep uncertainty looms over the Colorado River and the 40 million people who depend on it for their water supply. Plagued by decades of overuse and human-caused climate change, demand for the river’s water has vastly outpaced its supply. In 2023, [officials] must reduce use by 4 million acre-feet of water – 30% of what the Colorado River states have historically used.

from Bloomberg Green newsletter, January 3, 2023 Emissions are Growing Driving temperatures upward are record emissions of planet-warming greenhouse gases. Emissions from the burning of fossil fuels and cement production rose an estimated 1% last…

The last eight years are the hottest since global measurements began. If the first few days of 2023 are anything to go by, the warming trend looks set to continue. The year began with one of the most severe winter warm spells in European ….

Scientists say temperatures may breach the Paris Agreement’s lower limit of 1.5C within a decade.

Greenhouse gas concentrations in the atmosphere correlate to average global temperatures.  Pre-industrial levels of 280 ppm of CO2 meant temperatures about 1º C less than today.   The IPCC says that, if we     The…

The 2021 heat wave in the Pacific Northwest, which killed hundreds of people in the U.S. and Canada, was a harbinger of a new generation of climate disasters to come, a new study in Nature Climate Change shows.

This is a long article, but very well-researched and sobering.

A once-unfathomable scenario — Lake Powell dropping to historic lows and shutting down power generators that serve millions — could start as soon as July.

The Washington Post looked at 1,200 possibilities for the planet’s future. These 230 are our best hope. Do-able, but urgent. We can do this!
