Is Global Warming caused by Carbon Dioxide increasing?
I didn’t ask is technology causing global warming . That’s a more complex question.
This Video called “The Great Global Warming Swindle” gives some credible arguments suggesting that sun spots and cosmic rays both caused by the sun have a far greater affect on the earths temperature.
There is a good page at BraveNewClimate.com that debunks some of this
The biggest surprise to me was that CO2 makes up less than 1 percent of the earths atmosphere.
I’d like to know how the sun’s activity is measured because they have data going back hundreds of years.
So one fair conclusion to draw is that many people take for gospel that Global warming is caused by CO2 and one might ask “What good does it do to prove that is false?” Not a lot really. But it’s nice to know the truth. It’s also possible that if I was more vocal about this that I’d be helping the anti-nukers to delay the growth of Nuclear Energy.
Some points made in the video as fact
1. That CO2 is only about .54 % of the atmosphere (it’s more like .038 %)
2. That Margaret Thatcher offered scientists money to prove that CO2 was causing Global warming.
3. At a relatively low period of industrialization in the first few decades of the 1900′s we had a far greater increase in CO2
4. There is evidence that CO2 increase is caused by Global warming and that there is a time lag and that Al Gore’s theory did not dig deep enough to see the patterns. (Gore did get some of it wrong but what’s important is his call to action – after all CO2 is an enabler for temperature change so what came first before humans were causing it is not so relevant)
Questions unanswered and a couple of strange and unlikely facts. The ocean has a memory and temperatures are very slow to respond to influences as much as 300 years.
Also what about Ozone and if we’re not worried about CO2 then is there something we should be worried about?
