Well personally I'm not that convinced about 'climate change' either. I mean I'm convinced that the global climate can and will continue to change, as it has done for millions of years, but I'm not that convinced that human activity has as dramatic an impact as people claim, nor that we have to drastically alter our behaviour in the near future in order to 'save the planet', the planet itself will do fine without us, but we might end up with some serious floods in popular coastal areas and low lying countries like Bangladesh I guess.
At the same time we've only been keeping detailed records for about 500 years, and we've only been burning fossil fuels in vast amounts for about 100 years, and we are already on the verge of switching over from 'gas guzzlers' to hybrid/electrical or fuel cell powered vehicles, and will probably have more or less completely switched over by 2050, (you know, they'll probably have a new 'scrappage scheme' to get people to replace old petrol/diesel vehicles with electric ones once the technology has matured a bit more and prices fall), and hopefully also be able to switch over power stations to power those electric vehicles to safe nuclear, renewables or even maybe fusion if we can finally get it to work.
So you could say future generations will see we have a strange 150year 'blip' in historic ice core samples or whatever, in terms of a small human-generated uptick in carbon dioxide emissions, but the relative amount of impact that has on global temperature fluctuations is debateable, when we consider all the other factors that have a larger impact over much longer time periods. (Erm, didn't the atmosphere use to consist of almost entirely carbon dioxide, before some kind of bacteria came along and started polluting it with that dangerously combustable and highly corrosive substance called oxygen? Gosh isn't it terrible it's now up to something like 21% of the entire atmosphere, heaven help us if there are lightning strikes making the trees all catch fire).
Things like solar cycles, super-volcanic eruptions etc, that we can't hope to have any reasonable control over, have always dramatically affected the earths climate and ecosystems to a far greater extent, for millennia before we were even aware of them.
So I'm not a 'stick my head in the sand and hope it all goes away' type, or an 'ignore all those petty concerns while there's still more money to be made' type, but I do think a lot of it is overblown and alarmist, and we should really stick to engineering better solutions to existing technical challenges, than getting all upset with each other for holding conflicting belief systems about systems that are probably too complicated for anyone to grasp the whole of, as part of a kind of sublimated in-group/out-group tribal conflict, (same goes for Linux/Windows, (I mean how many people have even heard of Dave Cutler etc.), or PC/Mac), or as a replacement for a kind of religion, when most people seem to be playing off emotions based on misinformation rather than facts.
There's already a generation coming up behind me that's never known any version of Windows before Windows XP, as much as I have always known about cars and was never faced with learning to ride a horse or drive a cart, when my mum born in 1950 grew up in a world when only relatively rich people even had cars, and most everyone else just had to walk everywhere or take the bus.
Likewise there will be a generation born soon that won't believe that only 50 years ago people actually used to actually compete over whose car had the biggest engine, or the most chrome fins, instead of over whose car was the most eco-friendly, had the longest lasting battery, and had the best self-driving operating system and personal communication, navigation and entertainment gadgets in the inside, gadgets which make a lot of diffference to the travelling experience but which actually use relatively little energy, and don't weigh the car down so much that it actually needs a 4 litre engine to move around.
I'll be nearly 70 in 2050, and I fully expect that by then young-whippersnappers will be aghast that I even once drove a car with a 1.4litre Diesel engine, and had to learn how to work manual transmission, and wasn't really allowed to take my hands off the wheel to change the TV channel for sometimes hours at a time.
