For the love of rocks

We often have a way of seeing patterns in otherwise random features, and rock outcrops are no exception. Do you see the heart on its side? To the untrained eye an outcrop like this is simply a heart-shaped feature in an otherwise grey rock. But to the geologist, the layers, swirls, shapes and colours tell a story. The ribbons in the granite show that the rock has been subjected to sheer forces and ...[Read More]

What did the IPCC say about aerosols?

Aerosols dominate the uncertainty in the total anthropogenic radiative forcing. A complete understanding of past and future climate change requires a thorough assessment of aerosol-cloud-radiation interactions. This is one of the conclusions about aerosols and their impact on our climate from the the final report from the Intergovernmental Panel on Climate Change (IPCC) on the physical science bas ...[Read More]

The Earth’s protective shield

I came across this video, which very clearly explains how the Earth’s magnetic field protects us from Solar Storms. It then goes on to explain the link of these phenomena to our planet’s climate. The added bonus is that the images are  very cool and I think the voice over is done by  Liam Neeson…. Does anyone else think so? Anyway, I digress… For a written account of what i ...[Read More]
