Climate change will fix itself eventually. It's just a matter of waiting until the current mass extinction includes us, then a few tens of millions of years for everything to settle down again.
The current global model of asset-stripping the planet for the short-term benefit of a wealthy elite is guaranteed to wipe us out, and I can't see that changing any time soon. We've known all this since at least the 1960s, probably much earlier.
Don't forget to buy your patio-heater gas (I saw a lorry-load being delivered to a DIY store yesterday). That atmosphere won't heat itself - burning fossil fuels just to heat up the outdoors is a great short-cut to our genocide. While patio-heater gas is available in the shops, raising carrier bag prices in the UK to 10p to save whales in the Antarctic Ocean is just blind-siding the peasants.
