Carbon emissions 'will defer Ice Age'

Human emissions of carbon dioxide will defer the next Ice Age, say scientists.
The last Ice Age ended about 11,500 years ago, and when the next one should begin has not been entirely clear.
Researchers used data on the Earth's orbit and other things to find the historical warm interglacial period that looks most like the current one.
In the journal Nature Geoscience, they write that the next Ice Age would begin within 1,500 years - but emissions have been so high that it will not.

Earthquake Swarm Keeps Iceland’s Katla Rocking

We’ve been keeping an eye on Iceland’s Katla for quite a while now and over the past year; the volcano has been showing signs that magma is moving under the ice-capped edifice. There have been frequent seismic swarms around and within the caldera that is currently filled with the Mýrdalsjökull (glacier) and on at least two occasions, small glacial outburst floods (jokulhlaups) have issued from Katla.
