Is it hot in here, or is it just me?

[Army of GOD]

I've been subject to three graphics in this thread. The first shows it is hot. The second shows that three years prior, it was cold. Juan has a lot of things on it. What does it all mean? Does anyone have a graphic comparing those three graphics?

Juan's graphic is in Australian. I can't understand it.

It means that in the summer, the normally cold air over the arctic in the last several years has been shifting and going south. One year mostly over the US, but perhaps the next year, mostly over Russia.

Although (apparently) the average temperature on Earth has not changed/has insignificantly changed in the past 16 years, the climate is changing--but this means that in general colder climates will become warmer, and warmer climates will become warmer.

So, areas which yield lower productivity of various crops will now become more productive, and I see this as a good thing.


What are the net effects of climate change?

Does anyone really know, and if they can't answer that, then why follow their policy prescriptions?

People do actually know. As the tropical belt increases, areas that are currently major food suppliers (bread basket, etc) will experience a shift towards a more tropical climate. This allows for invasive species and diseases to cause environmental havoc to plants and biosystems that can't adjust quickly or well enough to a sudden shift in climate (30-60 yearsish). Areas with a greater absolute latitude from the equator that you are talking about may or may not be able to grow those crops of which you speak.

It takes much more than good weather to make a plant grow.

This idea is nothing foreign to Environmental Scientists.

I, for one, welcome the day when I can walk around in December in shorts. Like, seriously, I'm most comfortable when it's about 100 during the day and 80 at night.

Get those exhausts fumes pumping, people. I don't ever want to wear pants or a jacket again.

Well of course it was "hot" ... it was an election year. (Duh.) You really should study politics.
