More than a third of the world’s nations “urgently need help” to build up resilience if their economies are to withstand the effects of global warming.
If the world heats to 2.9 degrees Celsius or more, the 65 most vulnerable nations will see their average GDP drop by 20 percent by 2050 and 64% by 2100.
The warning was sent in a report commissioned by Christian Aid, and was published at the COP26 climate talksMonday in Glasgow
If their economies are to survive the onslaught of natural disasters, more than a third need urgent help. heatwaves. drought. floods and stormsAccording to the report,
According to the study, even if global temperatures rises are limited to 1.5C, these same countries would have a GDP growth of 13 percent in 2050 and 33 per cent by the end of this century, according the Paris Agreement goal.
The average surface temperature of the Earth has been recorded to date. has risen 1.1CComparable to the late 19th-century levels.

“The ability to countries in the Global South to sustainably develop is seriously jeopardised,” said the study’s lead author Marina Andrijevic from Humboldt University in Berlin.
“Policy decisions that we make now are crucial to preventing further damage”
Sudan is the country with the greatest GDP loss. In September, it was hit hard by flash floods and heavy rains that displaced more than 300,000.
The country would see a 32 percent GDP drop by 2050 and an 84 percent reduction by 2100, respectively, compared to if there were no climate change.

Storm surges that are worsened by rising seas are particularly dangerous for small island states.
“Africa has done the most to cause climate changes, but this report shows it will.” most severe consequences. This is deeply unfair,” said Mohamed Adow (director of Power Shift Africa, a Nairobi-based climate and energy thinktank).
However, the study fails to consider adaptation measures which could mitigate some of this damage.
