This is so beautiful 🥺

"There is no question more urgent than the one indicated by that red arrow in the graphic above.

Global temperatures in 2023, 2024—and now 2025—are smashing records. Something is accelerating global warming faster than expected—and the scientific community doesn’t fully understand why.  James Hansen, the former NASA scientist who first warned the U.S. Congress about global warming in 1988, is sounding a new alarm. He says cloud feedback may be turbocharging the climate system, making Earth 50% more sensitive to CO₂ than previously believed."We Don't Have Time

James Hansen’s New Paper and Presentation: Global Warming Has ACCELERATED

September 2023 was Earth’s most extreme month for heat ever recorded » Yale Climate Connections

Climate scientist James Hansen says the world may soon exceed the 1.5 degree Celsius warming threshold.

More climate news that Republicans will tell you to ignore.

This is by Jeff Masters, a professional meteorologist and co-founder of Weather Underground – a pioneering weather site started in 1995.

September 2023 smashed the record for the most extreme month for heat in Earth’s history, recording the highest departure from average of any month in analyses dating back to 1850, said NOAA’s National Centers for Environmental Information on October 13. NOAA, NASA, Berkeley Earth, and the European Copernicus Climate Change Service all rated September 2023 as the warmest September on record, crushing the previous September record by a huge margin. And famed climate scientist James Hansen warned today that the world is on the verge of exceeding the 1.5 degree Celsius warming threshold seen as key to protecting the world’s people and ecosystems — a claim still hotly contested within climate science. According to NOAA, September global temperatures spiked to a remarkable 1.44 degrees Celsius (2.59°F) above the 20th-century average. The September 2023 global temperature anomaly of 0.46°C (0.83°F) surpassed the previous record-high monthly anomaly from March 2016 by 0.09°C (0.16°F). Using NASA data, September 2023 was 1.7 degrees Celsius above the temperature of the 1880-1899 period, which is commonly called “preindustrial” (the difference between the 1951-1980 baseline reported on the NASA website and the 1880-1899 period is 0.226°C). This is the first time that a monthly temperature has exceeded 1.5 degrees Celsius above preindustrial temperature threshold in the NASA database.

Rightwingers make up bizarre excuses to keep us using fossil fuels. It's not unexpected that religion would make an appearance on the climate-denial stage. In the 2010s, hate monger Bryan Fisher told listeners and viewers that it was an insult to God not to use fossil fuels.

Back to reality...

The year-to-date period of January-September is the warmest on record globally. According to NOAA’s latest Global Annual Temperature Rankings Outlook and the statistical model it uses, there’s a greater than 99.5% chance of 2023 being the warmest year on record. At the start of this year, few experts foresaw 2023 as being a contender for Earth’s warmest year, as the bulk of El Niño’s warming comes during the second year of each El Niño rather than the first — so it’s possible that 2024 will be even warmer than this year.

There's a climate-denial industrial complex with deep pockets willing to spend big to buy politicians to keep fossil fuel corporations cranking out carbon.

We need to support viable candidates and politicians at every level of government who favor the transition to Earth-friendly energy.

Expert climatologist says the Earth is heating up even faster than predicted

James Hansen began sounding the alarm on climate change in the 1980s. The situation is only getting more dire

‘We are damned fools’: scientist who sounded climate alarm in 80s warns of worse to come

James Hansen, who testified to Congress on global heating in 1988, says world is approaching a ‘new climate frontier’

The world is shifting towards a superheated climate not seen in the past 1m years, prior to human existence, because “we are damned fools” for not acting upon warnings over the climate crisis, according to James Hansen, the US scientist who alerted the world to the greenhouse effect in the 1980s.

Hansen, whose testimony to the US Senate in 1988 is cited as the first high-profile revelation of global heating, warned in a statement with two other scientists that the world was moving towards a “new climate frontier” with temperatures higher than at any point over the past million years, bringing impacts such as stronger storms, heatwaves and droughts.

The world has already warmed by about 1.2C since mass industrialization, causing a 20% chance of having the sort of extreme summer temperatures currently seen in many parts of the northern hemisphere, up from a 1% chance 50 years ago, Hansen said.

“There’s a lot more in the pipeline, unless we reduce the greenhouse gas amounts,” Hansen, who is 82, told the Guardian. “These superstorms are a taste of the storms of my grandchildren. We are headed wittingly into the new reality – we knew it was coming.”

Hansen was a Nasa climate scientist when he warned lawmakers of growing global heating and has since taken part in protests alongside activists to decry the lack of action to reduce planet-heating emissions in the decades since.

Climate movement grandpa James Hansen says the Green New Deal is ‘nonsense’

His solution to climate catastrophe? You may want to sit down for this one: a carbon tax.

Excerpt from this Grist story:

In the 1980s, NASA scientist James Hansen brought climate change to the attention of Congress, and shortly thereafter the public. Humans, he testified in 1988, were responsible for rising global temperatures.

But the man who put his reputation on the line to alert the world to the dangers of global warming doesn’t appear to agree with the most recent crop of climate advocates.

In April 20 debate with Sunrise Movement’s Varshini Prakash and Christian Aid’s Amanda Mukwashi, Hansen called the Green New Deal “nonsense.”

Hosted by Al Jazeera, the 12-minute debate highlights a growing fault line between two theories of climate action. Among progressives and environmental justice advocates, the Green New Deal represents a last-ditch, economy-wide overhaul. Hansen, on the other hand, seems to argue for a more economically incremental approach that is centered on a carbon tax.

That tension came to a head when Hansen appeared visibly aggravated by the progressive proposal and Prakash, realizing that one of the most prominent climate scientists in the world was scoffing at her organization’s central focus, could only laugh in disbelief.
