According to Weather Source, over 6,900 fires have been recorded in Angola and 3,400 in DR Congo this week; compared to over 2,000 in Brazil. But experts say it's difficult to compare. "Fire in Africa... is part of a cycle, people in the dry season set fire to bush rather than to dense, moist rainforest," said Greenpeace's Philippe Verbelen.

Almost a million hectares (3860 square miles) of forest and farmland have been destroyed in Bolivia over the past few weeks by largely unchecked wildfires, with scientists and indigenous leaders already branding it the country's biggest disaster for biodiversity. Small farmers often practice the slash-and-burn method — known locally as chaqueo — as a quick and easy way to clear land.

The start of the dry season has sparked Indonesia's worst annual fire season since 2015. A state of emergency has been declared in six provinces, including Sumatra and the Riau Islands. Like Brazil, Indonesia is home to some of our planet's oldest tropical forests, but large areas have been lost to agriculture or other commercial interests.

A wildfire raged through the Spanish holiday island for over a week this month, threatening several parks rich in biodiversity and forcing thousands to evacuate. Spain is often threatened by massive forest fires, especially during the hot, arid summer months. Experts say climate change means these events will likely become more severe and frequent.

Large swathes of land in Siberia have been engulfed by wildfires this season, prompting a state of emergency in four regions. Forest fires are a natural event in Siberia, but unusually warm weather this summer combined with strong winds meant a record 5.5 million hectares of forest was burning by mid-August, creating a cloud of smoke which covered a greater area than the EU!

Greece is on high alert as hot, windy weather fuels dozens of fires across the country. Hundreds of people had to be evacuated from the holiday island of Samos. Fires in Greece are often blamed on people ignoring safety rules during severe weather conditions, such as throwing away lit cigarettes or barbequing outdoors. More than 100 people were killed in a wildfire outside Athens in July 2018.

Australia is no stranger to bushfires. But they are becoming increasingly common even during the winter months thanks to warmer-than-usual temperatures. Tinder-dry conditions have forced some states to bring forward the start of the bushfire danger season to August 1. Between August 22 - 23 this year Australia recorded 768 bushfires — slightly higher than the number of blazes burning in Bolivia.

Beginning on June 8, three wildfires in Central Arizona have burned through 14,000 acres of land. Wildfire season is usually quite active in Arizona due to its dry climate. Unless they pose a threat to human life, many fires are contained and managed rather than suppressed. On average, over 2% of the land has burned per decade since 1984 — a figure likely to increase as the climate warms.

Although there is a combination of factors behind the numerous jellyfish that reach vacation havens like the Mediterranean coast, climate change is also partially to blame. Warmer sea temperatures are opening up new areas where jellyfish can reproduce, and increasing the availability of their favorite food: plankton.

Prized for their superior sound quality, an original Stradivarius can sell for millions of dollars. Yet, extreme weather events, such as unusually violent storms, are killing millions of trees, putting at risk the famous wood in the Paneveggio forest, in northern Italy. Replanting trees won't help much in the short term. A spruce has to be at least 150 years old before it can become a violin.

On very hot nights, people sleep worse, especially in big cities. By 2050 European metropolises may experience temperatures around 3.5 degrees Celsius warmer in summer. It not only affects sleep, but also mood, productivity and mental health. The only way to escape is to move to smaller towns and settlements, where the nights are cooler since there are fewer buildings and more greenery.

Spring is starting earlier in the year due to global warmer temperatures — bad news for allergy sufferers. With a longer frost-free season, plants have more time to grow, bloom and produce pollen. Therefore, pollen will freely roam around much earlier, which will make the suffering season longer and the annual pollen load greater. Will it be the century of masks for air pollution and allergies?

Heat not only makes us sweat; it also affects our health. By the end of this century three-quarters of the world's population is expected to be exposed to dangerous and deadly heat waves. Rising temperatures mean an increase in diarrheal diseases, as it's easier for bacteria to multiply in warm food and water. Mosquito numbers will also likely go up, along with the spread of diseases like malaria.

Soil in the region around the North Pole is increasingly thawing in the summer months, with dramatic local and global consequences. Warmer temperatures cause floors to become unstable and houses and roads to crack, and leads to many more insects. Moreover, if permafrost — frozen soil — melts, it will release CO2 and methane gases that could further exacerbate global warming. It's a vicious circle.

Temperature can influence the sex of several species. For sea turtles, the heat of the sand where the eggs are incubated determines the sex of the newborn. Low temperatures benefit male turtles, while females develop better in warmer areas. Researchers have found that over 99% of turtle hatchlings in northern Australia are already female, making it difficult for the species to survive.
