The global warming signal is now louder than the noise of random weather, as I predicted would happen by now in the journal Science in 1981. Extremely hot summers have increased noticeably. We can say with high confidence that the recent heat waves in Texas and Russia, and the one in Europe in 2003, which killed tens of thousands, were not natural events — they were caused by human-induced climate change.
The hottest month in US history was July, 1936.
The hottest week in US history was during July, 1913 in Death Valley California. The hottest temperatures in Arizona history occurred twenty years ago. No continent has set an all time heat record in over 40 years. Europe’s record temperature occurred during the 1880s. Half of US states set their all time temperature record during the 1930s.
When Hansen reports “we can say with confidence” – who is he talking about? What caused the hot weather in the 1930s?
we can say with high confidence that Hansen is losing it. Those heat waves in Russia were caused by the jet stream – this was well documented. Revising history appears to be the only weapon left in the arsenal of the warmist nutters. So sad he’s been reduced to this – lying his butt off in a desperate attempt to appear relevant.
In the US, there has not been any heatwave recently that could match the widespread 110+ heat that took place in 1934 and again in 1936.
Does anybody have a good article on atmospheric blocking that we can send him. He seems to ignorant of this effect that is typical of a cooling climate.
Summer of 1976 in Maine, there was no rain for 15 weeks, over 100 deg F on the coast, and 12 million chickens died of heat stroke—they had to call out the National Guard to help with the many tons of dead bird. This was just before the coldest part of the last temperature cycle. It’s called atmospheric blocking.

“we can say with high confidence that Hansen is losing it.”
Lost it?
Martin Hoerling:
In his recent New York Times Op-Ed piece, Jim Hansen asserts:
“Over the next several decades, the Western United States and the semi-arid region from North Dakota to Texas will develop semi-permanent drought, with rain, when it does come, occurring in extreme events with heavy flooding. Economic losses would be incalculable. More and more of the Midwest would be a dust bowl. California’s Central Valley could no longer be irrigated. Food prices would rise to unprecedented levels.”
He doesnt define “several decades,” but a reasonable assumption is that he refers to a period from today through mid-century. I am unaware of any projection for “semi-permanent” drought in this time frame over the expansive region of the Central Great Plains. He implies the drought will be due to a lack of rain (except for the brief, and ineffective downpours). I am unaware of indications, from model projections, for a material decline in mean rainfall. Indeed, that region has seen a general increase in rainfall over the long term during most seasons (certainly no material decline). Also, for the warm season when evaporative loss is especially effective, the climate of the central Great Plains has not become materially warmer (perhaps even cooled) since 1900. In other words, climate conditions in the growing season of the Central Great Plains are today not materially different from those existing 100 years ago. This observational fact belies the expectations from climate simulations and, in truth, our science lacks a good explanation for this discrepancy.
