According to the National Oceanic and Atmospheric Administration (NOAA), the past April was the warmest globally since record taking began in the late 19th Century. Combining both land and ocean temperatures, the NOAA recorded that April 2010 was 0.76 degrees Celsius (1.37 degrees Fahrenheit) above the 20th Century average.
Particularly warm areas on land included South Asia, northern Africa, Canada, Alaska, the Eastern US, northern Russia, and Australia.
The NOAA also reports that Arctic sea ice was below normal for the 11th April in a row. Measurements found that the sea ice was 2.1 percent below the 1975-2000 average, yet was the largest since 2001.
If trends continue, 2010 could become the warmest year on record. To date, according to NOAA data, 2010 has proven to be the warmest January-April yet. The past decade, from 2000-2009, was the warmest on record.
Scientists say that the world is currently undergoing warming due to carbon and other greenhouse gas emissions from human activities, such as burning fossils, deforestation, and land use changes.

(02/25/2010) As a child when I came down with pneumonia my parents did not rush me to see a policeman, a cattle rancher, or a local businessman. Instead they took me to see a medical doctor—someone who had studied that science for at least twelve years—and I was quickly given injections and put on antibiotics. Thanks to my parents’ ability to tell the difference between experts and non-experts, I survived.
(01/24/2010) According to NASA’s Goddard Institute for Space Studies (GISS), last year was tied for the second warmest year on record after 2005, the warmest year on record. If just looking at the southern hemisphere, however, 2009 proved the warmest yet recorded since record-taking began in 1880. Overall 2009 tied a total of five other years—four from the 2000s—for the second warmest on record. But, researchers say what is most important was that the past decade, from January 1st 2000 to December 31st 2009, proved the warmest on record.
(12/08/2009) As 192 countries meet in Copenhagen to wrangle out a complex and at times sticky agreement to combat climate change, the World Meteorological Organization (WMO) has released new evidence that the world is undergoing warming. According to the WMO the current decade is likely the warmest on record.
