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.
