Global warming evidence is ‘unmistakable’

A new report released by the Met Office and the National Oceanic and Atmospheric Administration (NOAA) has come to the conclusion that there is "unmistakable signs" that "the world is warming".

The report is based on 10 different indicators of temperature changes. According to the Met Office each indicator "proved consistent with a warming world". According to the report the air temperature over land, the sea-surface and marine air temperature has all increased. Our oceans are also heating and the humidity is getting higher. Tropospheric temperature in the ‘active-weather’ layer of the atmosphere closest to the Earth’s surface has also increased. The Met Office also notes that sea-levels has increased while glaciers, spring snow cover in the northern hemisphere and arctic sea-ice are all in decline.

“The temperature increase of one degree Fahrenheit over the past 50 years may seem small, but it has already altered our planet,” said Deke Arndt, co-editor of the report and chief of the Climate Monitoring Branch of NOAA’s National Climatic Data Center.

“Glaciers and sea ice are melting, heavy rainfall is intensifying and heat waves are more common. And, as the new report tells us, there is now evidence that more than 90 percent of warming over the past 50 years has gone into our oceans.”
