Heavy rain and rising waters continue to take a deadly toll in countries including Nigeria, Thailand and Vietnam

It has been a drenched 2022 for many parts of the world, at times catastrophically so. A year of disastrous flooding perhaps reached its nadir in Pakistan, where a third of the country was inundated by heavy rainfall from June, killing more than 1,000 people in what António Guterres, the UN secretary general, called an unprecedented natural disaster.

While floods are indeed natural phenomena, a longstanding result of storms, the human-induced climate crisis is amplifying their damage. Rising sea levels, driven by melting glaciers and the thermal expansion of water, are increasingly inundating coastal areas, while warmer temperatures are causing more moisture to accumulate in the atmosphere, which is then released as rain or snow.
