Humans Are Causing Earth's Seasons To Change In A Way Never Seen Before

A study in the journalSciencehas found that humans are induce a direct effect on Earth ’s atmosphere in a way not seen before .

Specifically , scientists extend by the Lawrence Livermore National Laboratory ( LLNL ) in California found that humanity is likely leaving a “ fingerprint ” on the planet ’s seasons . The temperatures of each season are being forthwith affected .

study the troposphere , which extend up to 16 kilometers ( 10 miles ) above the tropics and 13 kilometers ( 8 sea mile ) above the perch , they found a global - mean annual average warming of 0.7 ° C ( 1.25 ° F ) from 1979 to 2016 . And the perpetrator look to be humans .

“ Our results intimate that attribution studies with the changing seasonal cycle provide herculean and refreshing evidence for a substantial human effect on Earth ’s mood , ” said LLNL clime scientist and lead source Benjamin Santer in astatement .

The team , whichThe Guardiandescribes as “ the undecomposed of the best climate scientist studying Earth ’s atmosphere , ” used temperature measurements from satellites to make their findings . They then used computer example of the mood based on greenhouse gas pedal emanation from humans , ascertain against a manakin with no human influence .

The results showed a fingerprint of man - caused global heating in the troposphere that could not be accounted for by rude clime variability . A consequence is that the “ heartbeat ” of season , namely the shift from cold winters to spicy summertime in the Northern Hemisphere , is becoming potent .

One of the changes seen is that in mid - latitudes in the Northern Hemisphere , the summertime is getting warm quicker than the wintertime . They say this may be due to the large amount of land in the Northern Hemisphere , which is dry in the summer . The same effect was n’t as apparent in the Southern Hemisphere because it consist more of water .

At the poles , something more unnerving was happening : the seasons seemed to be disappearing entirely . As ice melts and more water is unearthed , the temperature variation between season seem to be diminish .

The report comes as countries around the world , include theUKandJapan , are experience tempestuous heatwaves . Humanity ’s effect on the climate has been well documented – but now it appears it is have other unseen effects on the atmosphere , too .

“ The piling on of evidence is worry me , ” Santer toldBloomberg . “ This is the form of stuff and nonsense you do n’t want to be right about . ”
