Fifty years ago, global cooling was causing collapse of the Gulf Stream.  Now. global warming is causing collapse of the Gulf Stream.

“Pack ice around Iceland is becoming a serious navigation hindrance to an extent unmatched since a “little ice age” in the 17th and 18th centuries.

England’s growing season has shortened a week to two weeks since 1950 and the Arctic ice and snow cap has expanded 12 per cent since 1964.

North Atlantic surface waters have been cooling for the last 30 years. The tepid Gulf Stream, a major warming influence on Western European weather, has retreated south about a sixth as far as it did at the height of the last full-fledged ice age, 20,000 years ago, according to ocean bed fossil records.”

“Yes, global warming is considered a significant factor in the potential collapse of the Gulf Stream”

“We see a tipping point occurring right before our eyes,” Hansen told the AP before the luncheon. “The Arctic is the first tipping point and it’s occurring exactly the way we said it would.”

Hansen, echoing work by other scientists, said that in five to 10 years, the Arctic will be free of sea ice in the summer.

Longtime global warming skeptic Sen. James Inhofe, R-Okla., citing a recent poll, said in a statement, “Hansen, (former Vice President) Gore and the media have been trumpeting man-made climate doom since the 1980s. But Americans are not buying it.”

But Rep. Ed Markey, D-Mass., committee chairman, said, “Dr. Hansen was right. Twenty years later, we recognize him as a climate prophet.”

In 2018, CNN said President Trump was being ridiculous for criticizing California’s handling of wildfires.

So far this month, January has been the 14th coldest on record in the US, after NOAA predicted a warm January.

The Associated Press documents that Biden’s green policies failed, and is upset that President Trump doesn’t want to pay $7 billion for seven EV chargers.

“Last year set a record for high temperatures across the mainland United States, with the nation also pummeled by a barrage of tornadoes and destructive hurricanes, the National Oceanic and Atmospheric Administration said in a report Friday.

The announcement came as Europe’s climate monitor confirmed 2024 was the hottest year globally, with temperatures so extreme that the planet breached a critical climate threshold for the first time ever.

President-elect Donald Trump, a vocal climate skeptic, is just days away from taking office and has pledged to expand fossil fuel production — the main driver of human-caused warming — while rolling back the green policies of his predecessor, Joe Biden.”

“Lisa J. Graumlich, who examines the ring patterns of foxtail pine trees and western junipers in the Sierra Nevada, has compiled a detailed record of the year-to-year variation in temperature and precipitation over the last thousand years.

She has seen in the North American trees the feathery but unmistakable signatures of the Medieval Warm Period, a era from 1100 to 1375 A.D. when, according to European writers of the time and other sources, the climate was so balmy that wine grapes flourished in Britain and the Vikings farmed the now-frozen expanse of Greenland; and the Little Ice Age, a stretch of abnormally frigid weather lasting roughly from 1450 to 1850. A Crucial Question

“We can now see that these were global climate phenomena, not regional temperature variations,” she said. “The question is, how did we get those warmer temperatures during pre-industrial times, and what can we learn from those conditions about what is going on today?”

By her analysis, the 20th century has seen more exaggerated swings in moisture than during any comparable period in the last millennium. She and others at the laboratory are particularly concerned because the tree rings clearly declare that in the Western United States, the years 1937 through 1986 have been abnormally wet compared with past centuries — and these are the years of the greatest immigration to the supposedly golden coastal states.”

Fires also leave revealing scars in the tree tissue, and if enough trees in a wide enough region prove to bear fire scars at the same time, researchers can guess the year was extremely dry, for aridity invites a blaze’s spread. Studying fire marks in giant sequoias, Thomas W. Swetnam and co-workers have discovered that major conflagrations sweeping across many mountain ranges in California and the Southwest were a long a common feature, occurring at least twice a decade and apparently linked to oceanic currents much farther south, the so-called La Nina events that often result in droughts.

“Finding this synchronicity in fire events was a big surprise to us,” he said. “It tells me that Western landscapes in presettlement era were very smoky places.”

But by the end of the 19th century, settlers seeking to carve out grazing terrain for their livestock had cleared away much of the forest undergrowth that had served as fodder for the fires, and oscillating fire cycles became a thing of the past. So, too, did the long-term vitality and diversity of many forests, and park and wilderness managers are now seeking Dr. Swetnam’s advice on how to recapitulate, in a controlled manner, the synchronous infernos of the past. “We made the forests safe for cattle,” said Dr. Swetnam, “and now we must make them safe for fires once again.”

LOS ANGELES, Nov. 24, 1938—(U.P.)—Eight brush fires, fanned by high, dry winds from the Nevada desert, were out of control in Southern California today after burning over 50,000 acres of land and destroying more than 600 homes.”
