2008 is on track to be one of the ten warmest years on record. Rebecca Williams has more:
Scientists keep track of how hot and how cold it gets in places all over the planet. And this time of year they tally up the data.
Karsten Shein is with the National Climatic Data Center. He says 2008 was a cooler year – but it still ranks as one of the top ten warmest years in the past century.
“We do see there are periods where temperatures have gotten cooler for a short period of time and periods where temperatures have gotten warmer for a short period of time but over the entire period of record we’ve seen a general warming trend.”
Shein says many places around the planet continue to have more extreme weather – more rain, more heat waves and more snow.
