In summer 2021, drought and low humidity combined with record-breaking heat of up to 48.8°C (119.8°F) led to fire outbreaks across the Mediterranean countries, killing more than 100 people and burning more than 620,000 ha of land in July and August

Southern Madagascar’s worst drought in 40 years led to severe stress on vegetation, triggering a drastic decline in rice, maize and cassava production. By December 2021, more than 1.6 million people were estimated to have been suffering high levels of food insecurity.

During the 2020-2021 typhoon season, for the first time in 56 years, no typhoon made landfall on Taiwan, leading to one of the worst droughts in the island’s history. As reservoirs fell below 5% capacity, more than one million households and businesses had to ration water.

On 15 January 2022, the Hunga-Tonga-Hunga-Ha'apai volcano eruption was felt across the Pacific Ocean and beyond, releasing energy equivalent to hundreds of Hiroshima nuclear explosions and creating supersonic air pressure waves that were observed from space.

In 2020, the Arctic had the second-highest air temperatures and second-lowest area of sea ice coverage on record. Temperatures reached 38.0°C in Verkhoyansk, provisionally the highest known temperature anywhere north of the Arctic Circle.

Between 2019 and 2021, swarms of desert locusts formed and spread across 23 countries on multiple continents, including Djibouti, Eritrea, Ethiopia and Kenya. They devoured their weight in vegetation every day. One mega-swarm alone, measured in Kenya in 2020, was the size of the country of Luxembourg.

During summer 2020, around 2,300 km of the Great Barrier Reef in Australia was affected by a record mass bleaching event where corals expel their algae and turn white. Over 25% of the Great Barrier Reef suffered severe bleaching, seriously threatening them with extinction.

From 11 to 20 February 2021, a powerful cold wave swept across North America. In Texas, the freezing temperatures killed at least 210 people and caused the power grid to fail, leaving 3.5 million people without electricity and heat.
