Summers Could Last Half A Year By 2100, If Global Warming Continues – India Times
Turns out, you’re not the only one who thinks that summers are getting longer and hotter. Scientists warn that summers are already 18 per cent higher than what it was 60 years ago and could last until six months by the end of the century if global warming continues unchecked.
And unlike those in the 1950s, future summers will be even more harsh, with increased heatwaves and wildfires.
The study, published last month in the journal Geophysical Research Letters, examined how climate change is affecting the pattern and duration of Earth’s seasons.
Researchers used historical climate data to measure how much the seasons have changed already. They found that the average summer in the northern hemisphere has grown from 78 to 95 days between 1952 and 2011, while winter has shrunk from 76 to 73 days.
On average, the spring seasons shrank from 124 days to 115 days, and autumns shortened from 87 days to 82 days.
Using climate change models, the researchers predicted several scenarios with the help of available data. The worst case scenario saw summer lasting for nearly six months and winter being reduced to just a couple of months.
The greatest changes could be seen in the Mediterranean region and the Tibetan plateau, but the effect will be felt elsewhere in the world as well.
These irregularities, scientists said, could have a series of serious consequences to human health as well as the environment.
Changes to Earth’s seasons could wreak ecological havoc, causing changes to species’ life cycles and disrupting migration as well as will expose people to more allergenic pollen and longer allergic periods.
“In addition, tropical mosquitoes carrying viruses are likely to expand northward and bring about explosive outbreaks during longer and hotter summers, especially when introduced into regions without previous occurrence,” the report added.
