Climate change may extend for next 10,000 years
#Cosmoread: The damaging climate consequences of carbon emissions will grow and persist for millennia without a dramatically new global energy strategy, a new study has warned.
Rising global temperatures, ice field and glacial melting and rising sea levels are among the climatic changes that could ultimately lead to the are home to 1.3 billion people today, researchers said. “What our analysis shows is that this era of global warming will be as big as the end of the Ice Age. And what we are seeing is a massive departure from the environmental stability civilization has enjoyed during the last 10,000 years of its development,” said Jeremy Shakun from Boston College in US.
For the study, and international team of researchers generated new scenarios for temperature rise, glacial melting, sea-lever rise and coastal flooding based on state of the art climates and ice sheet models. They used a projected global output of 1,280 billion tones of carbon across the next few centuries, far below estimated reserves of at least 9,500 billion tons.
The projected consequences at this lever of carbon emissions include an increase in the global average temperature, which will exceed the recognized ‘guardrail’ of two degrees Celsius, and melting of glaciers and the massive ice sheets of Greenland and Antarctica which will combine for a rise in sea levels of 25 meters, researchers said.
The study also found that coastal submersion could displace as many as 1.3 billion people worldwide, a number that now accounts for approximately 19 per cent of the world’s population. As many as 25 ‘megacities’ around the world could see rising oceans force at least 50 percent of their populations from their homes and businesses, researchers said.
The perspective on the future looking projections comes from looking back at the last Ice Age, which ended approximately 10,000 years ago.
