Climate Change Scenarios – Where are we headed?
For over a decade, future climate change impacts have been assessed using a number of standardised emission scenarios. These scenarios assume different future states of the world’s population and corresponding greenhouse gas emissions – from really optimistic to really grim. For more information on these scenarios, please see IPCC SRES Scenarios and RCP Scenarios. It is important… Read more »
A New Revelation in Geophysics

There has always been evidence supporting the interaction between the atmosphere and the ocean and the interdependence of the two, so no declaration of such findings is going to come as any sort of shock.

Why we should be concerned about what’s happening at SAWS
pdf version: blog2 I have an admission to make: I’m a weather freak. I find the daily weather bulletin (dwb) as riveting a read as Stieg Larsson’s Millennium trilogy and browsing through climate statistics as exciting as watching the IPL final.

Medicine for the planet… or ourselves?
So far, several geoengineering options have been proposed to counter the effects of global warming. Anders Sandberg, an ethicist at Oxford University in the United Kingdom, recently considered a ‘safer’ route: although (admittedly) not entirely serious about the idea, he thinks that human engineering poses less danger than altering our planet through radical geoengineering options….
