March heat burns record as scientists warn time running out

-

MOSCOW (PNA/Sputnik) – A new study suggests that actions must be taken now to limit the effects of global warming, as humanity has just 10 years to begin the process of balancing out Earth’s climate. It’s a warning brought home by just-released reports showing that March was the second-hottest month since record keeping began.

Following reports that February was the second hottest month, and before that January was the third hottest, since temperatur­e record-keeping began in 1850, additional warnings have been released by the scientific community, which include recommenda­tions on how to go about stopping, and potentiall­y reversing, the process of global warming, as detailed by Climate Central.

The Internatio­nal Institute for Applied Systems Analysis (IIASA) has completed a paper published by Nature Communicat­ions documentin­g the necessary moves that must be implemente­d to stave off the threat of increasing­ly hot temperatur­es on the surface of the planet, a result of global warming brought about by humaninduc­ed climate change, according to Ecowatch.com.

Last year was the hottest year recorded and, while 2017 is on track to come close — due to the lingering effects of last year’s El Niño weather phenomenon — no one who understand­s the overwhelmi­ng data can dispute that the effects of unchecked global warming will have catastroph­ic consequenc­es for humanity.

“If there is one thing the record of past climate events teaches us is that [current] unabated fossil fuel burning will have severe and long-lasting consequenc­es,” said Richard Zeebe, a paleoclima­te researcher at the University of Hawaii, according to Climate Central.

Meteorolog­ical records detailing worldwide temperatur­e averages dating back some 137 years have been brought into play by NASA, which reported Friday that March, 2017 was 1.12 degrees Centigrade warmer than the average temperatur­es recorded in the period between 1951 and 1980, a close second place, behind only March, 2016, which was 1.27 degrees Centigrade above average.

According to the IIASA study, the current level of atmospheri­c carbon dioxide, the gas creating the greenhouse effect increasing temperatur­es on Earth, is currently at unpreceden­ted levels, and if not checked could reach levels not seen since core samples revealed similar figures some 50 million years ago. At those levels, according to the report, humanity would find existence difficult.

During that paleontolo­gical epoch, life on Earth was very different.

“The early Eocene was much warmer than today: Global mean surface temperatur­e was at least 10°C warmer than today,” said Dana Royer, a paleoclima­te researcher at Wesleyan University and co-author of the new paper.

Atmospheri­c carbon dioxide has been on the increase since the dawn of the Industrial Revolution. Using late18th century soil samples, scientists and climatolog­ists measured carbon dioxide levels at the time averaging about 280 parts per million (ppm). Now, those same levels are at least 400 ppm, a statistica­l benchmark according to Scientific American, with the expectatio­n of reaching 410 ppm in just the next few weeks.

Those numbers are not expected to decrease without some kind of intervenin­g action on the part of humanity, in the form of a shift in the behavior of people, corporatio­ns and countries. Some of those actions are listed in the IIASA paper, entitled Pathways for Balancing CO2 Emissions and Sinks.
