Earth is at risk into hothouse' state



The world is at risk of entering "hothouse" conditions where global average temperatures will be 4-5 degrees Celsius higher even if emissions reduction targets under a global climate deal are met, scientists said in a study published on Monday. The report comes amid a beatwave that has pushed temperatures above 40 degrees C (104 Fahrenheit) in Europe this summer, causing drought and wildfires, including blazes in Greece in July that killed 91 people. Currently, global uverage temperatures are just over 1 C above the pre-industrial period and rising at 0.17 degree C each decade, Scientists from the Stockholm Resilience Center, the University of Copenhagen, Australian National University and the Potsdam Institute for Climate Impact Research said it is likely that if a critical threshold is crossed, several tipping puints will lead to abrupt change. Such processes include permafrost thaw, the loss of methane hydrates from the ocean floor, weaker land and occan carbon sinks: the loss of Arctic summer sea ice and the reduction of Antarctic sea ice and polar ice sheets. "These tipping elements can potentially act like a row of dominnes, Once one is pushed over, it pushes Farth toward another," said Johan Rockstrom. co-author of the report published in the Proceedings of the National Academy of Sciences and executive director of the Stockholm Resilience Centre. "It may be very difficult or impossible to stop the whole row of dominoes from tumbling over. Places on Earth will become uninhabitable if Hothouse Earth' becomes the reality"

Commenting on the research, some experts said uncontrolled warming is still uncertain but not implausible. To avoid catastrophe, the researchers behind the new work said there was a need to move from exploitation to stewardship" of the earth, and not only reduce emissions but create new carbon stores- hy planting forests, conserving biodiversity and creating technologies to move carbon dioxide from the air.
