There are a few facts that are true beyond any doubt regarding Global Warming. These are:
1. During the 20th century the world experienced a warming trend in global mean surface temperature.
2. The trend totalled 0.6 degrees.
3. The world is constantly warming or cooling a few tenths of a degree every century.
4. Since 1998 we do not know whether we're still in a warming trend or not.
If you accept the Global Warming science on face-value, then what it means is that you'd accept that 0.6 degrees is attributable to human activity, with 47% attributed to CO2, 27% attributed to Methane and 22% attributed to black carbon* (I'm sorry I can never find the exact figures when I want them, I think they're correct, if you know where they are please link them, they come from NASA), here's a rudimentary link for the moment. So we can say that 0.3 degrees is attributable to CO2, so far, if you accept the science on face-value.
I don't. And I'm "so sceptical" that I think that CO2 is responsible for 0.1-0.2 degrees of the trend. Wow, didn't I just completely reject all the science? Pfft, hardly.
So in my mind, the worst-case scenario is that CO2 has contributed 0.2 degrees warming, and it's very difficult for it to contribute any more to global warming trends because it absorbs the vast majority of solar radiation reflected off the earth’s surface that it is capable of doing.
The lie told by alarmists is that CO2 is the main contributor - it's not. It's the main known single contributor, but it's not the main contributor. You can put 0.2-0.4 degrees of the trend down to natural causes, and that only leaves 0.4-0.2 degrees to work with for CO2 and the other anthropogenic causes, and as CO2 only contributes 1/2 (in fact less than half) with the remainder being made up by methane, black carbon, and CFC's, that means CO2 cannot possibly be driving climate change - it does contribute, but only very slightly.
I'd like to add to that one good volcanic eruption can spew out more CO2 then all human activity ever.
To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow, a poor player,
That struts and frets his hour upon the stage,
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.
