July, the hottest month of history. And for 2016 in a new record – The Republic

July 2016 was the hottest month of the story. The data released by the director of the Goddard Institute of Space Studies of NASA’s Gavin Schmidt, who posted on Twitter the chart with thermal curves. That of last month, highlighted, off the net all the others.

A long list of records. As is obvious, it was also the hottest July of all time since I started the instrumental and systematic measurements. The first data date back to 1880 but never the planet’s average temperature had risen so high: 0.84 degrees Celsius above the average taken as a reference of the 19501980 period, 0.11 degrees higher than the previous record, which belonged to July 2015. but the new peak is also the 15th warmest month in a row, when compared with the same month of the previous years.

June 2016 had recorded the record for June and the first half more than ever measured hot, and the sequence goes back, without solution of continuity, until October 2015 (according to the NASA). Until May instead according to the NOAA. Despite the difference in the type of measurements, data, alarming, it is the growing trend that shows no slowdown. Indeed.

“The 2016 will be the warmest year ever.” The forecast is far more of a prophecy, according to the Giss, and its director, c ‘ it is a 99 percent probability that this is the warmest year in the history of the measurements. The heat maps also show how the areas most subject to temperature increase are the most ecologically sensitive (as well as Siberia, Iran and the Middle East and South of the United States), especially near the north pole, where, for years, there is a alarming decrease of end cap cover. Since 2002, the ice of Greenland lost an average of 281 billion tons per year. Those Antarctic 118.

The first consequence of dissolution is represented by rising seas, which proceeds to 3.5 millimeters per year and has grown to 178 mm in the last century (from 87.4 mm 1990), according to the world Climate data Nasa http://climate.nasa.gov, which gathers the main parameters that measure the ‘fever of our planet.

Between levels kept under observation are the greenhouse gas emissions, the main culprits of rising temperatures. Also according to surveys by NOAA (the National oceanographic and atmospheric administration, the authority of the US climate and weather monitoring) carbon dioxide exceeded the global average of 404 parts per million in March 2015 and is still growing. So even in Antarctica, where they exceeded 400 ppm for the first time in four million years.

The “child” and the volcano. According to climatologists, the ‘ exceptional heat of the 2016 is also due to the ‘tail of El Niño, the periodic climate phenomenon that on average every five years raises the temperature of the Pacific ocean. Global warming, however, may have been attenuated even in the last 20 years due (or rather, thanks to) the eruption of a volcano in the Philippines. The Pinatubo in 1991, poured into the atmosphere a quantity of ashes and dust are able to do from the screen to sunlight. In the next decade, therefore, the effects of global warming may even be more intense and rising sea levels could be accelerated.
