For decades, the average temperature in the United States and the Arctic Sea-Ice volume remained relatively stable, despite an increase in atmospheric CO2 from ~300 ppm in 1920 to ~350 ppm in 1988.
And then something remarkable happened. Following Dr. James Hansen’s groundbreaking testimony before Congress, the US experienced a sudden and dramatic temperature increase. [emphasis, links added]
Could it be a coincidence that the temperature started rising just after Dr. Hansen’s warning? Or is there something more at play here?
Perhaps Dr. Hansen’s testimony unleashed a hidden force within the atmosphere, triggering an unprecedented warming trend.
While scientists continue to debate the exact cause of this phenomenon, one thing is clear: the timing of the temperature rise is undeniably suspicious.
It’s almost as if Dr. Hansen’s words held some magical power, conjuring up a surge of warmth and decreased ice volume that has persisted to this day.
So, what’s the real story behind this mysterious temperature jump? Is it a testament to Dr. Hansen’s prophetic insights or a sign of something more sinister?
The science from 1895-1987 showed no warming trend in the USA.
In fact, an article titled, “Are atmospheric “greenhouse” effects apparent in the climatic record of the contiguous U.S. (1895-1987)?” published in the prestigious journal Geophysical Research Letters stated…
The temperature and precipitation climate records for the United States have been examined. These records consist of area-averages across the contiguous United States and northern plains. They are based on as many as 6,000 stations. Time series of these data were tested for constancy of the mean using the Spearman rank test and two-phase regression. Test results indicate that overall trends are near zero.
Fascinatingly, the same can be seen in the Arctic sea ice volume. The Intergovernmental Panel on Climate Change (IPCC) has addressed Arctic sea ice volume and its relationship to GHG emissions in several of its reports, including the recently released Sixth Assessment Report (AR6).
They state that observed reductions in Arctic sea ice are strongly linked to human-caused greenhouse gas emissions and that reduced emissions would slow down future sea ice loss.
So let’s take a look at how Arctic sea ice volume has changed in relation to global CO2 emissions from energy and industry and James Hansen’s testimony.
It’s clear in the above image that Arctic sea ice responded very differently for the 88 years before Dr. Hansen’s testimony, gaining sea ice volume slightly, as opposed to the 30 years after, despite the ever-increasing anthropogenic GHG emissions.
Interestingly, despite the claims of recent years being some of the warmest, Arctic sea ice volume has been stable since 2018 and appears to be gaining presently.

Hansen has claimed that snowstorms are t he result of Global Warming/Climate Change which proves he a a False Prophit just like that phony Pope
Yes. He had to do that after 20 year old predictions of snow going away didn’t come true. Children still know what snow is. So he did what climate alarmists always do- open the window, observe what the current weather is then scream CLIMATE CHANGE as loudly as possible.
