Australia's drought - yes, it's climate change

Tim Radford

18th July 2014

Australia's prime minister thinks climate change is 'crap' and has just abolished his country's carbon-pricing system. But scientists say that it's rising levels of CO2 that are leaving the south of the country parched and sweltering - and it's only going to get worse. more...

Florida's collapse will set in within a 30-year mortgage cycle

Harold R. Wanless

3rd June 2014

We are most certainly witnessing the onset of a rapid pulse of sea level rise, writes Harold R Wanless. And low lying areas - like southeast Florida - will be the first to know about it. So how come they're building there like there's no tomorrow? more...

Greenland's glaciers 'more vulnerable' to rapid melting

Tim Radford

27th May 2014

Greenland's glaciers are more vulnerable to global warming than had previously been feared, reports Tim Radford, as ice bodies are undercut by seawater. The threat of rapidly rising sea levels just went up yet another notch. more...

West Antarctic glaciers 'past the point of no return'

Tim Radford

Strong winds keep Antarctica cold - while Australia bakes

Tim Radford

16th May 2014

Rising greenhouse gas levels are causing stronger winds over the Southern Ocean. It's good news for Antarctica, writes Tim Radford, as the circumpolar winds are keeping its ice caps cold. But Australia is getting hotter and drier - and its problems will only increase. more...

We must cool the Arctic before it's too late

Matthew Worsdale

29th April 2014

The decline of Arctic sea ice demands a response, writes Matthew Worsdale. As Arctic temperatures rise, so does the danger of huge eruptions of methane - a powerful greenhouse gas - that will tip the climate into 'hot'. The only solution is geo-engineering. more...

We must prevent abrupt climate change

John Nissen

8th February 2014

Weird weather from serious flooding in the UK to acute cold and drought in the USA follows from the warming Arctic and disruptions to the jet stream, writes John Nissen. We must act now to prevent sudden changes in global climate. more...
