The Start and the End of Our Interglacial

The previous interglacial (Marine isotope stage 5e, peaking at 125 kyr BP) is usually assumed to be a good analogue for our present-day climate. Moreover, as our present interglacial, the Holocene, is already almost 12 kyr long, paleoclimatologists were inclined to predict a quite close entrance into the next ice age. Simulations using the 2.5-D climate model of Louvain-la- Neuve show however that our interglacial will most probably last much longer than any previous one, even without human intervention (Berger and Loutre, 2002). It was suggested that this is related to the shape of the Earth’s orbit around the Sun ...

Detection and Attribution of Climate Change to Different Causes

According to the last IPCC report, the most part of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations. This statement relies on a long process of demonstration that consisted in evaluating the ability of the successive generations of climate models to reproduce and interpret the climate variability of the last decades. The more and more numerous statistical analyses aiming at detecting and attributing climate change to natural and anthropogenic causes have reinforced the assessment of experts. The recent detection and attribution studies of observed ...
