There are ways to reverse the worst effects of climate change if the world acts quickly, a new major report by scientists says.

Scientists from all over the world took part in the United Nations (UN), report which calls for countries to "super-charge efforts" to limit Global Warming.

It says that it's likely Earth will warm by over 1.5C - a temperature governments agreed to try not to go over.

But it also says there are lots of new eco-friendly technologies which could help slow down or reverse rising temperatures.

The latest report by top scientists in the UN says governments need to move forward their plans to cut emissions by ten years.

The boss of the UN says "immediately hitting the fast-forward button on their net zero deadlines" is the only way countries can help prevent issues caused by climate change.

But scientists say there are lots of new technologies which can help the world achieve this.

Renewable energy sources like solar and wind power have become much better in the last few years, and they're much cheaper than they used to be, they say.

They also point to technology like carbon capture which can suck up carbon dioxide (a greenhouse gas) from the air .

However, other scientist has expressed warnings about relying on those sorts of technologies because they're so new, aren't fully developed and may not work on the scale that is needed.

Scientists don't want the Earth's temperature to rise above 1.5C hotter than it was in the 1800s, but what happens if it does?

First, it's important not to panic, or lose hope.

One scientist, Dr Friederike Otto, who helped write the new report says: "If we aim for 1.5C and achieve 1.6C, that is still much much better than saying, it's too late, and we are doomed and I'm not even trying."

But the more the global temperature rises by the more likely it is that animals are exposed to temperatures too high for them to survive in.

The report also says that by 2100 floods which used to be so rare they happened once every hundred years could happen every year in some places.

Although climate change is a huge issue, and it needs countries and big companies to make changes, the UN suggests these ways you can help:
