Heavy rain has pummeled mountain communities in the US state of Kentucky. Water rushed down hillsides, swallowing towns, washing away homes and trapping hundreds of people. At least 30 people have been killed. US Vice President Kamala Harris said the flooding showed the urgency of crisis and announced $1 billion in grants to help states prepare for weather extremes worsened by climate change.

Scorching temperatures have been fueling wildfires in several countries. Spain, Italy, Croatia, France and Portugal have all reported forest fires that were linked to high temperatures. Heat waves are becoming more frequent and intense due to climate change, scientists say.

The start of July brought the fourth set of floods in 18 months to the Australian state of New South Wales. The Greater Sydney area was especially affected, with eight months worth of rain falling in just four days. Roads were turned into rivers and tens of thousands of people evacuated from their homes. Prime Minister Anthony Albanese said the repeated floods proved the need for climate action.

Storms have lashed Pakistan since mid-June, killing more than 70 people and damaging homes, roads, bridges and power stations. The country's minister for climate change said the recent rains were 87% heavier than the average downpour and that Pakistan should be ready to face more flooding as the warming world causes the country's glaciers to melt faster.

After scarce winter rains and months of drought, the Italian government declared a state of emergency in five regions. It will remain in place until the end of the year. Cities and districts have independently imposed restrictions on water usage. It is the most serious water crisis for 70 years in the country's Po basin region, which is vital for Italy's agriculture and livestock.

Even before the US wildfire season has officially begun, parts of the country are in flames. A fire erupted in northern California at the beginning of July and more than doubled in size overnight forcing hundreds of evacuations. It is just one of many fires burning across the state, 96% of which is experiencing drought, according to the United States Drought Monitor.

China is sweltering under the worst heat wave in decades. Scorching heat hit parts of the country in June and July, and air-con demand caused the electricity load in the eastern province of Henan to hit a new record. Meanwhile, the south has had heavy rain and floods. The government has blamed the extremes on climate change, which it says will increasingly impact both society and the economy.

Landslides and flooding following torrential rains wiped away housing in Brazil's northeastern Pernambuco state in May, killing at least 100 people. Favelas built on hillsides are prone to such disasters and experts say climate change contributes to more intense rainfall. The IPCC classified the low-lying metro region around the Pernambuco capital of Recife as one of the world's most vulnerable.

In April, intense rains hit the eastern coast of South Africa, causing floods and landslides that claimed more than 400 lives, destroyed over 12,000 houses and forced an estimated 40,000 people from their homes. A World Weather Attribution study found that climate change made the rains in South Africa twice as likely and up to 8% more intense.

East Africa is experiencing one of the worst droughts in decades. It started last year and is still ongoing after a fourth season of failed rains. Up to 20 million people are now at risk of severe hunger. Scientists say the decline in the spring rainy season, which is tied to warmer waters in the Indian Ocean, causes rains to fall rapidly over the ocean before reaching land.
