Yes, freaky weather for sure! But again we have to be sure to distinguish between weather and climate.
The thing I find interesting about melting ice, as a non-technical amateur, is after talking with a science teacher activist I know, finding out more about the latent heat of ice or the “Phase change”. (Sounds like something off Star Trek).
Basically, it takes far more energy to get the ice to the melting point than people realise. So when the Antarctic ice starts melting into the ocean, it’s not representing cooling moving into the ocean but an ENORMOUS reserve of extra atmospheric energy that is moving into the ice to turn it into water… thinking about it globally.
Then the albedo changes kick in, where once the ice acted as a mirror reflecting 90% of the sun’s energy the darker seawater now ABSORBS 90% of the heat.
In other words, right now ice is already absorbing heaps and heaps of extra atmospheric energy, disguising some of the warming, and bouncing back sunlight before it can transform into heat energy, preventing some of the warming.
When it is gone, we have the double whammy of less ice to act as a “sponge” absorbing heat and less ice acting as a mirror to prevent the heat in the first place!
It’s just one of many feedbacks that make this a very serious proposition.
In other words, the faster it warms, the faster it warms. The last time Co2 was this high was 15 million years ago,
“The last time carbon dioxide levels were apparently as high as they are today — and were sustained at those levels — global temperatures were 5 to 10 degrees Fahrenheit higher than they are today, the sea level was approximately 75 to 120 feet higher than today, there was no permanent sea ice cap in the Arctic and very little ice on Antarctica and Greenland,” said the paper’s lead author, Aradhna Tripati, a UCLA assistant professor in the department of Earth and space sciences and the department of atmospheric and oceanic sciences.
“Carbon dioxide is a potent greenhouse gas, and geological observations that we now have for the last 20 million years lend strong support to the idea that carbon dioxide is an important agent for driving climate change throughout Earth’s history,” she said.
