A heat dome is essentially stagnation. It forms as a strong high-pressure
system. As that air descends to the ground, it compresses and significantly
warms up: A few thousand feet up, air might be 80°, but it can reach 100° once
it hits the land.
This descending cap of hot air self-perpetuates for days or even weeks. It
discourages the formation of clouds, allowing the sun’s energy to hit the
landscape full force, further raising ground temperatures. At the beginning of
a heat dome, moisture in the dirt and plants evaporates away, somewhat cooling
the landscape—it’s sweating, basically. But as the heat continues for days on
end, that moisture runs out and temperatures climb higher.
In other words, the heat dome feeds on itself. “There is no cloud cover, there
is a lot of solar radiation coming in, there is no precipitation,” says
Claudia Tebaldi, a climate scientist at the Pacific Northwest National
Laboratory. “You also trigger this feedback—you dry the soil, and there is no
way for things to cool down by evaporation.”
Climate change, of course, is making extreme heat more extreme. “The trend of
temperatures increasing everywhere over time is unequivocal,” says Diamond.
“An average summer today, for example, might have been considered a hot summer
several decades ago. Likewise, a hot summer in the future may very well be
considered an average one a few decades from now.”

When the weather is a bit warmer than usual:
Experts*: IT'S PROOF OF GLOBAL WARMING!!!!!
When the weather is colder than usual:
Experts*: WEATHER AND CLIMATE ARE TWO DIFFERENT THINGS YOU MORONS!!!!!

Show me a climate alarmist claim and I'll show you a lie:
- EPA's heat wave charts begin in 1960. https://epa.gov/climate-
indicators/climate-change-indicators-heat-waves...
- But heat waves and data collection about them began long before, per the
National Climate Assessment.
Climate is a hoax.

I'm 63 years old and I've lived in the Pacific Northwest for 62 of 63 years and
I haven't found any evidence yet it's hotter now than it was 50 years ago. Some
years are hotter than others some years cooler than others.

The @washingtonpost
claims that 89 days over 90 degrees is a record for Fort Meyers, Florida.
In 1944, Fort Meyers had 169 days over 90 degrees.

Heatwaves were much worse when atmospheric CO2 was lower. It would appear that
we are headed in the right direction.

The official temperature record for North Dakota is 49.4C at 46N. That was set
in 1936 with CO2 not much above 300PPM. Your belief system is not based on an
understanding of history.

According to the @nytimes
China was much hotter in 1934. Nanjing was 115-120 degrees for weeks. This year
they are in the 80s.

Maybe in 1935, but so? And?
It was higher during the Medieval, Roman and Minoan Warm Periods, and DEFINITELY
hotter during the Holocene Climate Optimum(s).

"There is no doubt, that we need to have a complete transformation... the
transformation of the economy, and that includes, of course, the private
sector."
A carbon tax will change NOTHING, other than the wealth of politicians and
countries who beg us for money. THAT was the purpose of the Paris Accord... the
ONLY purpose.
Funny... when the government no longer pays for bogus money-grabbing data, the
truth comes out.

AOC's Top Aide Admits Green New Deal About The Economy, Not Climate
https://www.foxnews.com/politics/aocs-top-aide-admits-green-new-deal-
about-the-economy-not-the-climate
Rep. Alexandria Ocasio-Cortez's chief of staff recently admitted that the
Green New Deal was not conceived as an effort to deal with climate change,
but instead a "how-do-you-change-the-entire economy thing" -- a remark
likely to fuel Republican claims that the deal is nothing more than a
thinly veiled socialist takeover of the U.S. economy.
"The interesting thing about the Green New Deal is it wasn't originally a
climate thing at all," Saikat Chakrabarti said in May, according to The
Washington Post.
