Bangladesh – the great climate change exodus

Thousands of rural families in Bangladesh are being pushed into Dhaka and other crowded cities as their land and houses have been washed away, the New Internationalist reports. But by 2070, Dhaka itself will be one of the most climate-stressed cities on earth, according to the UN. Heat stress, river and coastal floods are likely if climate change continues unabated.

Bangladesh is calling for a new UN refugee convention to recognise climate refugees. In the meantime, Bangladeshis attempting to flee across the border to India face a fence-building programme along the border and gun-toting border guards who have shot a estimated 10,000 people trying to cross the border without papers in the last 10 years.

Sheffield Uni study shows Polar permafrosts could thaw and release stored carbon

Researchers at Sheffield University, working with other universities, have studied sudden climate warmings  that occurred around 55 million years ago and concluded that they were triggered by the release of carbon that had been stored in Polar region permafrosts.

This research suggests that a similar risk exists today, since rises in the earth’s average temperature could cause Polar permafrosts to thaw and release the carbon that is currently stored in them as decayed, frozen vegetation.

Cows fed linseed reduce their methane emissions by 40%

The Torygraph has an article about reductions in cows’ methane emissions (from farting and burping) when they’re fed on linseed.

30% of farm greenhouse gas emissions comes from methane from sheep and cattle, so if feeding them linseed reduced that amount by 40%, that means it would reduce overall farm greenhouse gas emissions by 12%. Given that the current target is an 11% reduction in farm greenhouse gases by 2020,  based on the 1990 level, this sounds too good to be true?
