There are 263 cross-boundary waterways in the world. Between 1948 and 1999, cooperation over water, including the signing of treaties, far outweighed conflict over water and violent conflict in particular. Of 1,831 instances of interactions over international freshwater resources tallied over that time period (including everything from unofficial verbal exchanges to economic agreements or military action), 67% were cooperative, only 28% were conflictive, and the remaining 5% were neutral or insignificant. In those five decades, there were no formal declarations of war over water2.

it is foolish for Israel, a water-short country, to grow and then export products such as oranges and avocados, which require a lot of water to cultivate

water 'embedded' in traded products could be important in explaining the absence of conflict over water

Study of the past can be informative for scientists, but it is not explanatory of the present nor is it predictive of the future.

The infamous "Hockey Stick" graph was featured prominently in the IPCC TAR Summary for Policymakers.

Two Canadians, an economist and a petroleum geologist, took it upon themselves to verify this proxy reconstruction by getting the data and examining the methodology for themselves. They found errors in the description published in Nature of the data used -- errors that prevented them from duplicating the study. Mann et al., the hockey stick's creators, published a correction in Nature, noting where the description did not match what had actually been done.

They're also growing vegetables — rather than crops like wheat — on floating gardens. They use a bamboo frame and load it with water hyacinth, which rots and makes a bed for vegetables to grow. Then when the flood water rises, they can still harvest food.

Record melting in northern Greenland and the widespread release of methane gas from formerly frozen deposits off the Siberian coast suggest that major changes are sweeping the Arctic

The study found methane bubbling up from the seafloor over hundreds of square kilometres in the Laptev and East Siberian Seas

Water measurements indicate that methane concentrations were up to 200 times higher than the background levels
