There is climatology and there is paleoclimatology. And then there is something in between. You thought yesterday´s trip to the early Pleistocene was geologically speaking exactly that, a trip to yesterday? Well, in that case today we go only a … Continue reading
One could focus on the rise in average temperatures and wonder to what extent this will increase the chance of weather extremes. One can of course also walk the opposite route: take a witnessed extreme – and examine if that … Continue reading

With the current La Niña strongly in place at the onset of the Australian monsoon and reaching predicted optimum strength at the height of the rainy season the risk of experiencing a repeat of the Queensland floods of 2010-2011 is … Continue reading
The most-quoted climate sensitivity range (IPCC 4AR) suggests a median temperature response to a doubling of the atmospheric CO2 concentration of 3 degrees Celsius – and a 66 percent probability range warming under CO2-doubling will be somewhere between 1.5 and … Continue reading
Of course you know these people that by now feel a bit cornered and say ‘okay, perhaps temperatures are going up. But that’s what it does, the global climate changes all the time.’ Well, to keep things simple: no, it … Continue reading
In our first ice age riddle a couple of days ago we looked at the link between CO2 rise and ice retreat, after the last ice age had reached its max, some 18,000 years ago.
