I'll give you that one, for very limited values of "much".
How's about a value of "much" of 100%? When I was at school, the percentage of CO2 in the atmosphere was accepted as 0.03%. Today's figure is 0.04%. Pre Industrial revolution it was 0.02%.
So, in the period occupied by the industrial revolution (okay, that's two centuries, not one) the CO2 levels have doubled. That's amazing!
The El Nino/La Nina cycle has driven or been driven by the South American Upwelling (not sure about cause and effect) for - according to geological evidence - maybe 150 million years. Global warming halted the upwelling in 1976.
For the past 40 years, most of "the ten hottest summers to date" have all been in the preceding decade. In other words, pretty much EVERY summer for forty years has either been a record breaker, or not far off it.
In other words, SOMETHING is up. Believe in global warming or not, as you wish. The evidence to me is frightening. And the consequences could be horrendous. How would you like to see sea-levels rise by metres over a period of days? That's quite plausible. What's going to happen when the Siberian Tundra melts? (They think that's gone past the point of no return already ...) Etc etc - we're in for an interesting century or two - I just hope it's not squashed into a decade or two instead ...
