But a US government report card says global warming is still dramatically altering the top of the world.The warming trend is reducing the number of reindeer and shrinking snow and ice, while increasing certain fish and extending the growing season.The National Oceanic and Atmospheric Administration issued its report on Thursday. It portrays conditions in 2013 as moderate compared to the roasting 2012. Overall Arctic temperatures didn't soar quite as high, and Greenland ice sheets and the summer sea ice did not melt as much.But NOAA says the long-term trends are ominous.
