“If we reduce emissions globally to net zero by 2040 there is still a two thirds chance to reach 1.5 degrees and if we globally achieve net zero emissions by the middle of the century, there is still a one third chance to achieve that,” she said.If all human emissions of heat-trapping gases were to stop today, Earth’s temperature would continue to rise for a few decades but would eventually stabilize, climate scientists say. If humans don’t emit any additional planet-warming gasses, then natural processes would begin to slowly remove the excess carbon dioxide from the atmosphere, and global temperatures would gradually begin to decline.

“There is a direct relation between delay and warming, and between warming and risk of what we would call extreme impacts,” said Ajay Gambhir, a senior research fellow at the Grantham Institute for Climate Change and the Environment, based at Imperial College London. “— whether it’s extreme heat waves, increased risk of crop failures, forest fires or bleaching coral reefs— already happening.”He added: “The further we delay action on addressing climate change by reducing our emissions, the warmer the world will get.”

During the monsoon season, which runs from June to October, many rivers change course, devouring markets, schools, mosques and homes near their banks.

Millions are at risk of being displaced and becoming “climate refugees” because of sea level rise, river erosion, cyclonic storms and salty water creeping inland, scientists say. Bangladesh is expected to have about a third of South Asia’s internal climate refugees by 2050, according to a World Bank report published last year.Mohammad Jewel stands on his land which was lost due to river erosion in Elisha Ghat area in Bhola, Bangladesh on July 4, 2022.

Jewel said the river never felt that close by as a child, but it inched nearer every year.
