Deniers will never admit that there is a problem, but what will happen is that the number of deniers will get fewer and fewer. I don't think we will have to wait long for that...Warmer1 said:
How do you do it? How are you able to maintain such 'great confidence' that anthropogenic global warming doesn't exist, when all the facts show otherwise?Arnold Martin said:
I think lots of people know there's weird weather going on, and are twigging that what scientists have been saying about climate change for a long time now maybe has something going for it.
Are you referring to the demographic imperative? I've noticed a distinct lack of new blood entering the circle. It's really a game for people past caring how ridiculous they make themselves.
Sent to Abandon All Hope, I suspect; a couple of my more frivolous efforts got swept up about the same time.
As shown in the figure above, all three series agree quite well on global temperatures. The dashed grey line shows the trend in temperatures since 2001, while the dashed black line shows the long-*‐term trend since 1970. While the rise in global temperatures has slowed in recent years, it is not obviously divergent from the underlying long-*‐term trend.
Here again the dashed grey line shows the trend since 2001, while the dashed black line shows the trend over the whole period.
Satellite records show some stagnation of temperatures in recent years, somewhere between the land and ocean surface records.
It is interesting to note that overall deep ocean heating (0-*‐2000 meters) shows no sign of a slow down in recent years, though shallower layers (0-*‐300 meters and 0-*‐ 700 meters) do. The fact that the slowdown in surface warming has been concentrated in the ocean surface temperatures (and not in land temperatures) has led a number of scientists to posit that the pause in ocean surface warming may be driven in part by increased heat uptake in the deep ocean.
Can global warming be real if it’s cold in the U.S.? Um… yes!

It's quite cold across much of the United States right now, thanks to the dread "polar vortex." Bitterly cold. Horrifically cold!
So what does this tell us about global warming? Not very much. Sorry. A single cold snap in the U.S. doesn't disprove global warming any more than the record heat waves currently hitting Australia prove that it's happening. But since a lot of people — like Donald Trump — seem confused on this point, it's worth recapping a few basics:
1) Global warming refers to the whole planet, not just the United States. The term "global warming" typically refers to the rise in the average temperature of Earth's climate system since the late 19th century, as well as predictions for future warming. A key bit there is "Earth's average temperature." It can be very cold in one part of the world and very hot in another at the exact same time. (Sometimes the exact same weather event can do both: The jet stream is currently making some parts of the U.S. unusually hot and some parts unusually cold.)
The winter blast
To trigger an El Niño requires significant warming of the ocean and a number of very strong wind blasts from west to east off the coast of Papua New Guinea. These blasts push the warm ocean waters to the eastern Pacific off South America and set up El Niño conditions.
This year has already seen three such powerful wind blasts. The most recent directly led to the tropical low that generated severe flooding in the Solomon Islands and later developed into Category 5 Tropical Cyclone Ita.

You're out by a factor of 10. And if you don't think a warming of 0.8 degrees Celsius in a century is cause for concern you don't know anything about climate change.
they are not pretty consequences and this but one aspect
It says nothing of the sort. The facts as they stand are alarming enough, there is no need for the video to exaggerate them. If you have some counter argument please present it but “that’s too scary to be true” isn’t an argument it’s a belief system.
As mentioned you are out by an order of magnitude. Warming since 1900 has been ~1 deg C which is phenomenally fast. That’s 10X faster than the average rate of warming that melted mile thick ice sheets that once covered most of North America. Business as usual is set to give us 6 degrees of warming in 300 years, that’s as much warming as there was in 6000 years at the end of the last glaciations.
Something supportable with papers in peer reviewed journals is always the requirement for a science discussion. Why would you even ask?
Both are highly respected scientists who both regularly publish papers on the subject of climate. While their opinions don’t trump their actual papers, it’s still a valuable and useful source of information.
Wow is this still a thing? The hockey stick has been confirmed many times and many ways, the claims it doesn’t exist have been debunked and disgraced over and over. You need to take a more skeptical view; it will help keep you from being lead around by the nose by this type of disinformation.
It's 1C surface warming in the last hundred years but that's not terribly material unless you know what that implies for the world. Which, I'm sure you'll agree, you don't.
