I have to admit that I was goaded back to this subject by the WP Brother-In-Law as we discussed the matter post-Thanksgiving dinner. He had moderated his viewpoint quite a bit, particularly in light of the original ClimateGate scandal and further investigation on his own. While he no longer automatically assumes any climate change is automatically our fault, he's still on the fence about what to do about it.
With ClimateGate 2.0 making the rounds, as well as more data showing the climate models being used to predict future global climate seriously underestimate the effects of some factors while overestimating others, making the models useless (most are so defective they can't even predict past climate, meaning using data sets that encompass several decades of weather data up in to the 60's and 70's they weren't able to 'predict' the climate we actually experienced in the 80's and 90's), the debate is heating up again.
I won't delve deep into the controversy as I have expressed my opinion about the “settled science” more than once – that there is no such thing. New data, new observations, disproved theorums, and new hypotheses can unsettle the settled science at any time.
One of the latest blows against the warmist claims is this report that CO2 may not warm the planet nearly as much as everyone thought.
The climate may be less sensitive to carbon dioxide than we thought – and temperature rises this century could be smaller than expected. That's the surprise result of a new analysis of the last ice age. However, the finding comes from considering just one climate model, and unless it can be replicated using other models, researchers are dubious that it is genuine.I find the last sentence to be hypocritical. How many of the claims made by the IPCC, UEA, and a host of other climate researchers are any more valid than the one from this analysis? Many of the critics of this report used cooked data, algorithms which give the same answers regardless of the data fed into them, and outright fraud to 'prove' their theories. Isn't that the pot calling the kettle black?
Another instance of hypocrisy: data from NASA satellites show the radiation of heat from the Earth into space is higher than many of the warmists believed. You would think that information would have some effect on their predictions, but all we've heard from them has been a muted “It doesn't make a bit of difference” and then silence. New data and observations in contradiction of 'settled' science are supposed to lead to further investigation and modifications to or scrapping of theories that are not supported by that data. Instead, it is ignored in order to preserve the theories so many have staked their reputations (and funding) upon. That is not how science is supposed to work.
And so it goes.
