WORLD'S OCEANS IN 'SHOCKING' DECLINE
The oceans are in a worse state than previously suspected, according to an expert panel of scientists. In a new report they warn that ocean life is 'at high risk of entering a phase of extinction of marine species unprecedented in human history'.

FOOD-PRODUCTION RACING TO BEAT CLIMATE-CHANGE
Across the globe, rising temperatures and more intense droughts, floods and storms are forcing a rethink in how to grow food, from breeding hardier crop varieties and changing planting times to complete genetic overhauls of plants, in a desperate bid to beat the effects of what we have done to the planet and sustain enough food-production for a growing population.

FASTEST C02 RELEASE AND HOT SUMMERS
The rate of release of carbon into the atmosphere today is nearly 10 times as fast as during the Paleocene-Eocene Thermal Maximum (PETM), 55.9 million years ago, the best analog we have for current global warming, according to an international team of geologists. Rate matters, and this current rapid change may not allow sufficient time for the biological environment to adjust. Full story at ScienceDaily. Second story on the same subject also at ScienceDaily.
The tropics and much of the Northern Hemisphere are likely to experience an irreversible rise in summer temperatures within the next 20 to 60 years if atmospheric greenhouse gas concentrations continue to increase, according to a new climate study by Stanford University scientists. The Stanford team concluded that many tropical regions in Africa, Asia and South America could see 'the permanent emergence of unprecedented summer heat' in the next two decades. Middle latitudes of Europe, China and North America--including the United States--are likely to undergo extreme summer temperature shifts within 60 years, the researchers found.
