Two seperate scientific studies have revealed that global warming is leading to significant reductions in the size of sheep and fish species, more evidence that climate change is forcing a huge range of species to adapt to a hotter world.

The first study, published in the Proceedings of the National Academy of Sciences, investigated fish populations in French rivers and the Baltic Sea and discovered that fish are shrinking as their habitats heat up.

Results show that average fish size in many French rivers have declined over the last thirty years, while the geographical range of tiddlers in the Baltic expanded as species such as herring and sprat also shrunk.

August saw the fastest retreat of arctic sea ice on record, according to new NASA data. During that month, sea ice melted at a rate of 32,700 square miles per day, compared with 24,400 square miles per day in 2007. The rate of decline is even more dramatic when compared with the 30-year average rate of decline, 19,700 miles per day.

The accelerated seasonal retreat of sea ice surprised NASA scientists, who expected a more moderate retreat on the tail of a la Niña year. Moreover, the data show that one cold year, when sea ice levels are able return to normal, is not enough to counter the long-term melting of the arctic.
