"Climate chage" is simply left-wing politics under another name.
For the record, climate change is real -- but that’s nothing new, just ask a wooly mammoth or a dinosaur. Atmospheric heat-trapping is also real, or else everything around us would freeze solid every night -- just as it does on our airless moon. And sea level is the best way to tell if the earth is warming or cooling because it is a truly global indicator, rather than a stew of various local measurements.
It is also important to understand the well-known cycles that bring us seasons and weather patterns. The seasons change from equinox to solstice over and over because the earth’s rotational axis is tilted relative to its orbital plane. During winter in the northern hemisphere, the sun appears in the sky farther in the south. It moves north until it reaches the summer solstice -- as the weather warms. Due to the elliptical nature of our orbit around the sun, the northern summer finds the earth farther away from its heat source than it is in the winter, which tends to moderate the seasonal temperature change.
The opposite is true for the southern hemisphere. Closer to the sun in the summer and farther in the winter would make for more severe weather down there, except for the much greater amount of the southern surface being covered by oceans, which also serve to moderate the weather.
Another axiom of climatology is that the west coasts of the continents have noticeably milder weather than the east coasts. This is probably due to the rotational direction of the earth, which is counterclockwise when looking down at the north pole.
Back to sea level and climate change. Previously at this site, Viv Forbes posted a link to NASA’s website showing

Racism is the most boring topic in the world.
Climate Change is the second most boring topic.
Not even worth refuting. These things are tools of the Left. They are not real topics.
Gotta throw “intersectionality” in there, too. I used to think it was, for example, when Auburn played Southern Cal.
Then it was at least interesting.
There are other climate events that aren’t explained. Why are there multi-decade or even multi-century cycles of climate? Why did the Medieval Warm Period or the Little Ice Age happen? Why were decades like the 1930s hot while the 1960s and 1970s cold (look how many of the daily record temperatures come from those decades)? And why does global warming baseline data always seem to start in 1940 instead of 1930?
Y’all have to remember most people are emotionally stupid that is why we have democrats, socialists, and “communists.
and are led more by emotion in some matters than whatever smarts they may have.
Democrat party is expert at this. They are the American Nazis and operate in lockstep. The rest of us question every authority, because we know authority is dangerous. However questioning is work, you have to learn, and think. Most people hated school, so they gave it up when they left, or earned their diplomas/degrees.
One thing this article gets wrong is that it calls the last glacial maximum the end of the ice age.
This is not correct. We are still in an ice age. Geologist define it as having ice at sea level anywhere, 24x7x365, which we do.
Wooly mammoth time was actually the prior maximum extent of the last glaciation.
We have had 60 such glaciations (and glacial retreats) in the past 4 million years. This is evidenced in layers of morraine in the geologic record.
BTW, ice age time vs non ice age time in earth history since life has been on the planet is about 25%, meaning it is much cooler now than it usually is.
AND as long as there is water around, warmer is actually better - that’s why there’s so much more life in the tropics than the temperate and frigid zones.
According to NASA, earth's atmosphere weighs 5.1e+18 kg (comes to ~5,600 trillion US tons).
According to The Engineering Toolbox, it takes 1006 Joules (of energy) to change the temperature of one kilogram of air by one degree Celsius (or Kelvin).*
1006 Joules/kg/°C per 5.1e+18 kg comes to 5.712e+21 Joules to raise the temperature of earth's atmosphere by a single °C (or °K).
5.712e+21 Joules converts to 1.425 trillion Mega-Watt hours.
The largest nukular reactor in the US (in Palo Verde, Ariz.) can produce 3937 Mega-Watts if all three reactors are running @100%.
Running @100% 24/7/365, in a year's time, Palo Verde would make 34,488,120 MWh.
Running at 34,488,120 MWh per year, Palo Verde would need 41,323 years to produce the 1.425 trillion MWh needed to raise the temp of earth's atmosphere by one degree C (1.8 °F).
Or to put it in another perspective, the Global Cooling Scare began about 1970. If we had brought enough reactors online that year in a deliberate effort to raise earth's atmosphere's temperature by 1°C (or 1°K, or 1.8°F) by running them @100% 24/7/365 until today, and converted ALL of that electrical output into heat, we would have had to build 780 Palo Verde-sized reactors (assumes 100% efficiency in the conversion).
Today there are only (roughly) 220 commercial nuclear power plants on the planet.
To put that in Imperial measurements (1°C = 1.8°F), Palo Verde would need 22,957 years to make enough MWh that if converted 100% to atmospheric heat could raise earth's temperature by 1°F.
Or if we had started in 1970, it would have taken 434 Palo Verde-sized reactors to raise earth's temperature by 1°F by 2023.
This obviously is an unfathomably YUGE amount of energy, far in excess of what a gas that comprises a whopping 0.04% of our atmosphere could be responsible for.
* Yes, I am aware this specific heat value only applies to air @sea level pressure but the scale of final answer is so absurd that I couldn't be bothered to find a mean value.
“Fossil Fuels” is another misnomer. The earth like a lot of bodies in the solar system has an abundance of hydrocarbons. There are seas of methane on some of the large planet moons. No fossils created them for sure.
The description of why the earth doesn’t freeze at night like the moon apparently doesn’t apply to Mars, where it does exactly that even though it has 10X the absolute amount of CO2 in its atmosphere but no green house effect at all. Could it have something to do with water and clouds instead of CO2?
I maintain that Neanderthals and their SUV’s caused the glaciers in NA to melt just because they wanted lake front property in Chicago.
if only we knew of an energy source so large that it could warm the earth for us at no cost.... hmmmm... i should apply for a government grant.
“And why does global warming baseline data always seem to start in 1940 instead of 1930?”
I saw a video of a guy do an “audit” of a global warming slide show. He got the slides and the source data for each slide. He showed that every slide had a different baseline date, and by going to the source data showed that every baseline date started at a point to make the subject look the absolute worse. When he moved the baseline back a few years, everything looked normal. I with I had kept that but I did not.
But but but you didn’t figure in cars or planes or factories or fireplaces or motorcycles or lawnmowers or weed eaters or trucks or gas stoves
Climate is natural all 17 of them
Any amount of high and mighty science is of no help to the women and minorities who are hardest hit
