Ancient Earth reveals terrifying consequences of future global warming
It reveals no such thing. It's only by making the false assumption that CO2 heats us up that they make this claim.
Even the current Greenie theory is that the earth will warm up by 2 degrees by the end of the century -- which is nothing compared to warming periods in the geological past. Just in the Earth’s geologically recent past -- the Paleo-Eocene Thermal Maximum of 55m years ago -- global temperatures increased by 5-8C
And all theories that predict a departure from a trend -- which the guff below does -- are the ones least likely to be correct. "New Scientist" started out as a Leftist rag and not much seems to have changed
The writer below, Graham Lawton, doesn't seem able to learn even from his fellow Greenies. Global warming theory Mark 1 predicted a tipping point (a stark departure from trend) due to warming from an accumulation of clouds. But clouds on all indications have a cooling effect so that theory was quietly abandoned in favour of an incremental theory. But slow increments are obviously way too boring for loony Lawton
WELCOME to Icehouse Earth. It may not feel like it but, right now, our planet is in an ice age. It started about 2.6 million years ago and, until recently, showed little sign of letting up. In the 1970s, scientists were even worried that we were about to plunge into another full-blown icy spell.
Today, those fears have evaporated into a fog of greenhouse gases. Unless we do something, fast, the exact opposite is going to happen. If emissions continue to accumulate in the atmosphere, Earth will blow its cool, with potentially disastrous consequences for humanity and the living world.
As the climate hots up, so does the race to understand what really happens when we crank up the thermostat. The standard approach is computer modelling, but we need every insight we can get, which is why some climatologists are turning their attention to the deep past, searching for global warming events to help predict the future. The good news is that the biosphere has endured some very hot periods and lived to tell the tale. The bad news is that the next hothouse may be more extreme than anything Earth has experienced before. In which case, it really is goodbye, cool world.
