The widespread decline in Arctic sea ice is causing big changes to the balance of greenhouse gases in the atmosphere, say researchers from Sweden's Lund University.
Researchers from Lund University in Sweden have successfully demonstrated how nanowires could potentially be used to pave the way for more efficient and cheaper solar cells.
There's been no simultaneous warming of the northern and southern hemispheres in the last 20,000 years, scientists say, indicating that climate change can't be ascribed to natural variation.
