However we shouldn't forget what's been happening on the planet's southern hemisphere:
The savage heat waves that struck Australia last year were almost certainly a direct consequence of greenhouse gases released by human activity, researchers said Monday. It is perhaps the most definitive statement climate scientists have made tying a specific weather event to global warming.And while it's winter up here, it's summer down there. And it's getting hotter and hotter in Australia.
Five groups of researchers, using distinct methods, analyzed the heat that baked Australia for much of 2013 and continued into 2014, briefly shutting down the Australian Open tennis tournament in January when the temperature climbed to 111 degrees Fahrenheit.
All five research groups came to the conclusion that last year’s heat waves could not have been as severe without the long-term climatic warming caused by human emissions.
What happens when a changing climate exceeds the operating parameters of the stuff we own? While we in the northern hemisphere make jokes about indestructible snow forts, it is getting hot in Australia. How hot? So hot that Australia’s Bureau of Meteorology had to add new colors to its weather map. Now, those unfortunate parts of Australia that achieve temperatures above 122ºF (50ºC) — temperatures that were, until recently, literally off the scale — will be marked in deep purple and terrifying hot pink. It is an interesting moment in data visualization history when climate scientists find themselves in the position of revising the upper bounds of temperatures they ever expected to depict.Something to think about as we see it snow in NYC or Boston.
