Fifty years from now we will be wondering why everybody thought the world was warmingJuly 7, 2014
In Forbes, of all places, there is an opinion piece by James Taylor (no, not that one) that talks about NOAA data showing the US as cooling by 0.4 degrees in the last decade, not warming as we are told to think. And in the UK Mail there is a piece that states that there is more Antarctic ice, not less.
What surprises me about the whole global warming meme is how easily it took hold, and how hard it is to shake it off, even with substantial evidence that the planet is not warming right now, and has not been for at least ten to twenty years. I know it was pushed by a bunch of folks who depend on government grants for their livelihoods, and rising seas, superstorms and other Roland Emmerich-style phenomena make for better copy than “well, the Earth is getting a little bit cooler, now, but not much.” Still, it amazes me that the kind of blatant cooking of data sets and backstage dealing to squash dissent we have seen has gone on for so long.
The sun is a variable star. Not much of one, thank goodness, or life couldn’t exist. But vary it does. We understand the sun less than we understand our own weather. For some reason, for example, the number of sunspots has been far less lately than expected. There are theories that say the sun doesn’t even use nuclear fusion, as most scientists believe. Neutrino counts from the sun are lower than predicted, but they are elusive little bastards, and it may be that our understanding of them is flawed.
In any case, what we have learned is that there is a lot we don’t know. Water vapor is a better greenhouse gas than CO2, but the Earth naturally regulates the amount of water vapor in the air. It may be doing the same thing with CO2, but the last I read the mechanism is not fully understood.
I would expect, however, that in 2064 we will be looking back on those silly scientists and politicians from fifty years before and shaking our heads at how they thought we were going to all be inundated by rising oceans and killed by superstorms. Do you remember a book called The Population Bomb? How about Silent Spring? 1960s and 70s doom-and-gloom predictions didn’t happen, and even the fear of civilization being destroyed by nuclear war went away, thanks to Ronald Reagan. I would like to be around to see what folks say about our silliness then. Maybe humanity will have matured enough to know not to run around crying “the sky is falling” when we don’t even know what the sky is made of.
