If two different metals are brought together, then an electrical voltage can develop if one metal is warmer than the other. This effect allows residual heat to be partially converted into electrical […]
Carbon released into the atmosphere by the increasing loss of Arctic permafrost, combined with higher solar absorption by the Earth’s surface due to the melting of sea ice and land snow, will accelerate climate change – and have a multi-trillion dollar impact on the world economy. A new paper in Nature […]
