Fertile Crescent ‘will disappear this century’
27 July 2009
Is it the final curtain for the Fertile Crescent? This summer, as Turkish dams reduce the Tigris and Euphrates rivers to a trickle, farmers abandon their desiccated fields across Iraq and Syria, and efforts to revive the Mesopotamian marshes appear to be abandoned, climate modellers are warning that the current drought is likely to become permanent. The Mesopotamian cradle of civilisation seems to be returning to desert.

Wild weather in the year ahead, scientists predict
12 July 2009
Climate scientists have warned of wild weather in the year ahead as the start of the global “El Niño” phenomenon exacerbates the impact of global warming. As well as droughts, floods and other extreme events, the next few years are also likely to be the hottest on record, scientists say

Study documents close relationship between past warming and sea-level rise
21 June 2009
The new record reveals a systematic equilibrium relationship between global temperature and CO2 concentrations and sea-level changes over the last five glacial cycles. Projection of this relationship to today’s CO2 concentrations results in a sea-level at 25 (+/-5) metres above the present.

Another tough summer for Arctic sea ice
5 June 2009
The annual melt-back of Arctic Ocean sea ice is deepening — driven by the arrival of warmer weather and the thinness of the winter ice that rebuilt after last summer’s melt.

Global emissions to leap 39 percent by 2030
27 May 2009
Global carbon dioxide emissions are set to rise 39 percent by 2030 as energy consumption surges in the developing world, notably in Asian giants China and India. The projections presume no legislative changes to cap emission levels or other initiatives to reduce the use of fossil fuels.
