Tech companies think they can reverse climate change with fancy new tools to take carbon dioxide out of the atmosphere. But new research throws cold water on the idea that cooling the planet after it has already heated beyond a key turning point can avoid serious damage.

If global warming reaches 2 degrees Celsius (3.6 degrees Fahrenheit), which could happen as early as the 2050s, such downpours are expected to occur nearly every year in the affected regions, WWA said,

In west and central Africa, heavy rains and flooding show climate change is another thumb on a scale already weighed down by war and disease.

Human-caused climate change worsened floods that have killed hundreds of people and displaced millions in Cameroon, Chad, Niger, Nigeria and Sudan this year, according to a study published on Wednesday.
