Events like this will become more common if we do not act now on climate changeLong-term shifts in temperatures and weather patterns. Human action is a major cause of climate change., expertsSomeone who knows a lot about a particular subject. say.

Here are five more predictionsGuesses about the future, often based on some evidence. for 2030:

1. Unique heat. By the early 2030s, 92% of countries will probably face "extreme heat" every two years, making it hard to grow food.

2. Deadly forecast. Between 2030 and 2050, climate change could cause an extra 250,000 deaths a year due to issues such as heat stress.

3. Renewable boom. The world is on course to power half the planet's electricity demands with renewable energyEnergy sources, such as wind and solar power, that do not use up fossil fuels and pollute the environment. by 2030.

4. Lost forest. BrazilThe largest country in South America, home to 217 million people.

Could science fix global warming?

Yes! New technology is allowing us to use renewable energy to power the world. By 2030 we could massively lower our greenhouse gasGases in the Earth's atmosphere that trap heat, contributing to global warming. Carbon dioxide, methane, nitrous oxide and water vapour are all greenhouse gases. emissions, which will help to fix global warmingThe Earth is getting hotter due to climate change..

No! The planet is still on course to keep warming up. This will do terrible damage to our planet, which cannot be undone. Scientists alone cannot fix global warming. Everyone has to act.
