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.

The solar cells, about the size of a 12-point font letter ‘o,’ are being tested to eventually power microscopic machines, such as those used to test chemical leaks in the air.
The researchers at the University of South Florida say these are some of the smallest solar cells ever, with twenty aligning to form one panel at just one inch. Typical single cells are around two inches across on their own, and then form the large silicon panels we see on rooftops.

German car-maker Audi has confirmed that it plans to launch a small electric city car, most likely based on the VW Up! concept (pictured).
Speaking at last weeks Paris Motor Show, Audi management board member, Peter Schwarzenbauer, said, “we will offer a pure electric car.” He also revealed that the electric Audi “will not be based on the A1,” the firm’s premium supermini.
