It’s been a while since we’ve passed along one of Peter Sinclair’s videos on climate change.
This is a good one:
Climate change got real for me in the sixth grade when I was warned of the next impending Ice Age.
The darn climate has been changing ever since then.
At least the planet is getting MORE green as the climate changes.
Did you know that the Earth is getting greener, quite literally? Satellites are now confirming that the amount of green vegetation on the planet has been increasing for three decades. This will be news to those accustomed to alarming tales about deforestation, overdevelopment and ecosystem destruction.
This possibility was first suspected in 1985 by Charles Keeling, the scientist whose meticulous record of the content of the air atop Mauna Loa in Hawaii first alerted the world to the increasing concentration of carbon dioxide in the atmosphere. Mr. Keeling’s famous curve showed not only a year-by-year increase in carbon dioxide levels but a season-by-season oscillation in the concentration.
Dr. Myneni reckons that it is now possible to distinguish between these two effects in the satellite data, and he concludes that 50% is due to “relaxation of climate constraints,” i.e., warming or rainfall, and roughly 50% is due to carbon dioxide fertilization itself. In practice, the two interact. A series of experiments has found that plants tolerate heat better when CO2 levels are higher.
The inescapable if unfashionable conclusion is that the human use of fossil fuels has been causing the greening of the planet in three separate ways: first, by displacing firewood as a fuel; second, by warming the climate; and third, by raising carbon dioxide levels, which raise plant growth rates.
Apparently Dr. Myneni’s satellite didn’t pass over my lawn this summer.
Steve-o, But Al Gore’s private jet did.
The same idiots who deny global warming also seems to be the same idiots who said nate Silver was a hoax and their gut or their feeling could make predictions better than math and science.
How did that work out for them.
