February 2016 is the warmest February on record, according to data released by NASA. Worldwide surface temperatures were 1.35 degrees Celsius warmer than average. That broke the record set in January, which was 1.15 degrees Celsius above average. Monthly temperatures were compared in the base years between 1951 and 1980. Some climate scientists were surprised by the extent of the warming. Jeff Masters and Bob Hansen from the website, wunderground.com, say the findings are “a true shocker.” They say it is another reminder of the continuing rise in the world’s temperature resulting from human-produced greenhouse gasses. Greenhouse gasses trap heat in the earth’s atmosphere. They are gasses like carbon dioxide, methane and water vapor. Climate expert Paul Knappenberger says the weather event El Niño is also to blame for this year’s high temperatures. El Niño is the result of a band of warm water in the tropical Pacific Ocean. When the heat from that water is released, the earth’s temperature goes up. Knappenberger says the combination of greenhouse gasses and the El Niño causes a slow rise in the earth’s overall temperature as short-term rises and falls take place. He adds that after an El Niño, there are often La Niña events. He said this can lead to cooler than normal weather conditions. El Niño and La Niña can shift back and forth every two to seven years, causing extreme weather.
