Exactly

Yeah, but that means nothing. Global warming refers to the average temperature over the entire earth, and that is unquestionably going up.

Sure, there will be places that will buck the trend. A river flows down hill, but there are always a few drops that splash upwards. Doesn't mean shit to the overall trend.

No. That would be global cooling.

We were quite likely headed in that direction, but we've turned 180 degrees.

degrees F or degrees C ?

Also Hawaiian Tropic gets my vote over Coppertone.

dinosaurs caused an ice age hundreds of years ago

1st it was Global Cooling n the 1970's,
then it turned to Global Warming..
then it turned into Climate Change
now it is Climate Chaos..


duh..

Really? This is just one more bit of denialist hogwash that just won't go away. Clifford Kraus started this myth by saying "there are more than 20,000 polar bears roaming the Arctic, compared to as few as 5,000 40 years ago." The trouble with that is, while the 20,000 is reasonably accurate (best current estimate 23,000), the 5,000 is nonsense. It's pure smoke and mirrors. One Russian author in 1956 said there might be 5,000 to 8,000 polar bears in the world. He didn't do any kind of counting, he just took anecdotal accounts from bear hunters and wildly extrapolated from there. Climate change deniers have latched on to the "5000" figure as if it was gospel truth (I wonder why they didn't latch on to the 8000 number instead?) and keep repeating it, despite the fact that its just a wild guess by one man who didn't do any real counting. Even rudimentary attempts at actually counting polar bears didn't begin until the late 1980s.

In the next 40 years or so we'll have much more accurate surveys. But going 50 years into the past, any number was pure guesswork.

Answered by Dr. Steven C. Amstrup, chief scientist with Polar Bears International and USGS polar bear project leader for 30 years.

Q: Why all the fuss about polar bears? Aren't their populations increasing: in fact, booming?

A: One of the most frequent myths we hear about polar bears is that their numbers are increasing and have, in fact, more than doubled over the past thirty years. Tales about how many polar bears there used to be (with claims as low as 5,000 in the 1960s) are undocumented, but cited over and over again. Yet no one I know can come up with a legitimate source for these numbers.

One Russian extrapolation presented in 1956 suggested a number of 5,000 to 8,000, but that figure was never accepted by scientists. The fact is that in the 1960s we had no idea how many polar bears there were. Even now, about half of our population estimates are only educated guesses. Back then, the best we had over most of the polar bear's range were uneducated guesses. Polar bear science has come a long way since then.

We do know (and I have published papers on this) that some polar bear populations grew after quotas were imposed in Canada, aerial hunting ceased in Alaska, and trapping and hunting were banned in Svalbard. All of these events occurred in the late 60s or early 70s, and we know some populations responded—as you would expect. Some populations were not being hunted back then (or were hunted very little) and those were probably unaffected by these three actions.

Back then, the sea ice was solid and not noticeably in retreat. With stable habitat, polar bears were a renewable resource that could be harvested on a sustainable basis.

But the most important point is that whatever happened in the past is really irrelevant. Polar bear habitat is disappearing due to global warming. Even the most careful on-the-ground management doesn't matter if polar bears don't have the required habitat.
