Environment

The southward shift of an atmospheric belt in the Southern Hemisphere since the 1970s is reportedly the reason why parts of Australia and southern Africa are drying out. The southward expansion of a meteorological feature known as the Hadley cell is most pronounced in autumn.

Hadley Cell

The southward shift of between 125 and 250 miles has resulted in less rainfall during April and May over southeastern Australia, and to a lesser extent over southern Africa.

Rain that previously would fall 125 to 250 miles farther north is now being directed that distance to the south due to climate change’s effect on the Hadley cell.

It is not known specifically what is causing the shift, and climate models have not accurately represented it.

Wildlife

A plan to cull thousands of wild badgers to stem the spread of tuberculosis in cattle is sharply dividing rural England. Marksmen could start the cull any day but details are being kept secret for fear of clashes between farmers determined to protect their livestock and livelihoods and activists who have pledged to foil the plan by scaring away the badgers.

Conservationists on Thursday asked a state judge to end trapping of wolverines in Montana, USA at a time when fewer than 300 of the elusive animals roam the Northern Rockies and Northern Cascades.

Montana is the only one of the lower 48 U.S. states that permits the harvesting of wolverines, carnivores that resemble small bears with bushy tails. They are sought for their fur.

Storms and Floods

Tropical Storm Patty has formed in the Atlantic east of the Bahamas, but forecasters expect the storm to be short-lived.

A violent tropical storm pounded coastal districts in southeast Bangladesh Thursday, killing at least 26 people. More than 1,500 fishermen who were fishing in the deep sea are still missing. At least 1500 mud, tin and straw-built houses were also levelled in the storms, leaving more than 100 000 people in need of aid.
