BOGUSOID #53
Animation of a polar bear swimming to a piece of ice, that breaks up.
Polar Bears have actually drowned because there isn't enough ice.
(ABSOLUTELY NOT TRUE!!! Polar bears can swim hundreds of miles. The polar bears that drowned, did so because of a storm. Most of the populations of polar bears that are being tracked are stable or INCREASING. )
BOGUSOID #54
Planetary consequences.
( Which is why we need to get it right, and not use false information, faulty logic, rhetorical trickery, jumping to conclusions, appeals to authorities, straw man arguments and the rest of the bogus arguments this movie is filled with..)
The circulation of the ocean currents.
BOGUSOID #55
A large engine for redistributing heat by wind currents and ocean currents. It is a non-linear system. Not gradual, sometimes big jumps.
(Umm. Then why should we expect his extrapolation of temperature rise earlier in the film to extend in a line as he implied? It can take big jumps in either direction, just as hurricanes do…)
BOGUSOID #56
The average world temperature is 58 degrees Fahrenheit. If we have an increase of 5 degrees, which is on the low end of the predicted rise, it isn't even, it may be one degree rise at the equator, but 12 degrees at the pole.
( or it may be 12 degrees at the equator, and 1 degree at the pole,…. Or it may be one degree cooler at the equator, and 12 degrees cooler at the poles…It hasn't happened yet, and for the past 10 years, the temperatures have been fluctuating, but staying somewhat around the same.)
All these wind and ocean current patterns which have formed since the last ice age and have been relatively stable, they are all up in the air, and they change.
One they are most worried about and have spent a lot of time studying the problem is in the North Atlantic where the gulf stream meets the cold wind coming off the arctic over Greenland and it evaporates the heat from the gulf stream and is carried over Europe.
Ocean conveyor. Red are warm surface currents. The blue are cold currents that run in opposite direction. They run along the bottom of the ocean. Cold, dense, heavy water sinks at the rate of 5 billion gallons per second.
BOGUSOID #57
After the last ice age, a huge lake formed in North America. An ice dam broke and diluted the stream and the heat transfer stopped and Europe went into another ice age for a thousand years. It went into that change in maybe 10 years. Is there any other big chunk of ice near there?
(Again with the unspoken implication, in this case, that Greenland might melt and cause Europe to go into an ice age for a thousand years. THIS IS NOT GOING TO HAPPEN. Ok, Greenland might melt. True. That is in the future, and Greenland has had tropical climate before in Earth's history. Won't be the first time. BUT, it won't melt and cause Europe to go into an ice age for a thousand years. For one thing, Al Gore used a map trick, to portray Greenland as far bigger relatively than it is. Our normal flat maps distort the image of Greenland (The areas near the poles are stretched out flat, remember?) and the ice sheet on Greenland is less than one fifth the size of the ice sheet that covered North America.
Second, the giant freshwater lake was dammed up across a huge section of central North America, and when the ice dam broke, it emptied out into the Atlantic within a matter of a couple of weeks. The topography of Greenland is such, that such a situation won't happen. Ok, so there will be small versions of that happening. In fact, one such glacial lake on Greenland did that very thing a couple of years ago. The last time I checked, Europe is not having an ice age. )
