In addition, fossil fuels are the only source of carbon consistent with the isotopic fingerprint of the carbon present in today’s atmosphere. That analysis indicates it must be coming from terrestrial plant matter, and it must be very, very old.

These and other lines of evidence leave no doubt that Fossil fuels are the Primary source of the carbon dioxide building up in Earth’s atmosphere."...""

How do we know the build-up of carbon dioxide in the atmosphere is caused by humans?

Fossil fuels are the only source of carbon dioxide large enough to raise atmospheric carbon dioxide amounts so high so quickly.

so many clowns, new and old here, say it's all natural
"it goes up, it goes down"
but scientists have actually looked into WHY this cycle is different than the others.

ALL CYCLES ARE DIFFERENT !!!!

Unless you are defining alternation of hot and cold as a cycle.
No one with a science education is going to go past the first paragraph.

It's going in the opposite direction now. 12 years of Temperature Reduction is now allowing for ice creation. Try to use your brains. And, it's the sun that is heating up the earth or cooling off. Do you think the sun is always giving off the same amount of heat every decade? No, it's in flux and we know this, don't we. It's not mankind to where you have to kill off 90% of humanity. But, you folk want to do this anyways, right? Let's start with your family first. How's that. Put your death where your mouth is. You people are horrible people. This is what happens when you deny God.

WTF!
Your Crazy deluded MFing Liar.
2016 Was the Hottest Year (with 2020 near tying it) until 2023, which is the hottest year in not only modern times, but probably in our entire interglacial period.

Dagosa is a troll. Ignore it and will die.

Remember, don't feed the trolls.

But this cycle is NOT Natural von-Bimbo.
Nature does not just decide to go at 100-200 Natural speed.
And that speed just happens to coincide with the CO2 WE Measurably put in/are still putting in.
Back to the religion section freak show with you now sister wack job .

again, the ice is gone. Now you can explain how it got warm enough to melt. Come now troll, we've been at this since November and you still haven't read what was posted.

Warmer than 32 F or 0 C.

Only an idiot thinks it has to be tropical to melt ice foolish. The sea ice is melting in the Arctic….but it sure ain’t tropical. The difference is idiot, the rate of melt is faster during the industrial revolution than any time man has been on earth…..illiterate….Every reference you can give from any science institute says it…you ARE ILLITERATE aren’t you.
It took tens if thousands of years for the glacier ice to recede from NA, not it’s receding faster…dufus.
we do this a few months and every time you deniers post you sound more stupid. Now, there are fewer of you

 

[Dagosa]

Again,

Dufus, read all of your buddy’s reference…it supports AGW…..hilarious.

You are math illiterate aren’t you. Read all of the reference you refer to. The rate of melt is accelerating dumb ass.

Hilarious…Robert W keeps using links that support AGW. The problem is, you bozos can’t read…

Where was it hottest? Not at Death Valley where it is our standard of temperature.

No it is not.

Hottest all time record was in 1913.

134 degrees Fahrenheit

On July 10, 1913, Oscar Denton, a U.S. Weather Bureau observer stationed at Greenland Ranch, in Death Valley, California, claimed the mercury hit an astonishing 134 degrees Fahrenheit, the highest temperature ever recorded in the United States.Jul 24, 2023

Correct, well said. It is people control, not climate control. Fantastic post

It’s fantastic to math illiterate science denying ignoramuses…You’re own fking links from Smithsonian support that you deniers are idiots.

YOUR REFERENCE FOOLISH.
“Today, the Barnes Ice Cap, a glacier about the size of Delaware on Baffin Island in Canada, is the last remnant of the mighty Laurentide Ice Sheet. But after 2,000 years of stability, the ice cap is expected to vanish in the next 300 years as an unparalleled rise in heat-trapping greenhouse gases has brought on an alarming rate of melting since the 1960s.“

That is not the hottest place on Earth. All you asked about was glaciers.

Twenty thousand years ago, Chicago was encased in ice roughly 3,000 feet thick — twice the height of Willis Tower. All that's left of the colossal ice sheet that sprawled over much of North America and formed the Great Lakes is a kernel of ice in the Canadian Arctic — and it's dwindling fast.Feb 28, 2019

The massive glacier that formed the Great Lakes is disappearing​

And Death Valley is what percent of the planet/GLOBAL Warming? .000001%?
I put up GLOBAL figures at the top of the page.

That was about a cold place.

Death Valley is the record place for heat. Stop shitting the people.

It is where the record was set way back in 1913. It is cooler now than back then.

And you used as a reference a source that supports AGW….how many times have you pulled this shit robert ? Maybe a dozen.
