There are only a few sources for climactic data.
I suppose there are, as for
climatic data, there are thousands of sources. Airlines send out atmospheric data in flight constantly, along with ground based stations sending weather baloons and collecting surface readings, this data is compiled, studied, used for forecasting and archived for use in statistics. Cherry picking data to suit a purpose and hiding what doesn't is what is causing this flap. And accurate historical data doesn't go back far enough to recognize what normal trends are.
But when people become sceptics just because they are too lazy or indifferent to change their habits, it's ridiculous.
It has less to do with being too lazy to change habits and more to do with resisting the transfer of wealth by government decree, (especially by foreign governments). If, in fact humans were the main cause of climate change we will end up living in mud huts heating with dirt to effect change, yeah, that's not a habit most of us want to get into.
As for misusing data to achieve an end, Britain and Europe are, or are going to heavily tax air travel, more heavily than any other mode of transportation, because of its impact on CO2 pollution. Yet air travel worldwide contributes 3%, yes that is
Three per cent, of all "greenhouse gasses" emitted into the atmosphere. This directly hits my bottom line, sure the customer pays, but so do all the operators, employees, and businesses connected to the industry. This is an "in your face" cash grab that will have no effect on pollution and just enrich the money grabbers. Living will get quite a bit more expensive and we may well be relegated to freezing in mud huts, but by order of the power brokers. So yes, I'm skeptical.
The story isn't over with CO2; the most effective greenhouse gas is water vapour. It is present in the atmosphere in quantities thousands of times higher than CO2 and burning hydrocarbons produces lots of it. That'll be the next target. By the way, the most destructive substance in the atmosphere is oxygen. These are natually occuring gasses and are necessary for life, and they will be here in varying degrees of concentration long after we're gone, just as they were before we arrived.
The data says what the data says. Earth is warming. Show me data that shows otherwise.
I'd like to see the data that shows that it is, the untarnished data. We're not going to see it, and even if we did we couldn't come to any more of an accurate conclusion than all the scientists have so far, but enough doubt has been cast on the current zeitgeist that I think skepticism is warranted.
