You may have heard that the UK is hosting a summit called COP26 which is seen as being really important if climate change is to be brought under control.
The COP26 event is a global United Nations summit about climate change and how countries are planning to tackle it.
It was due to take place in Glasgow in Scotland in November last year with more than 200 world leaders due to attend, but it was delayed for a year because of the coronavirus pandemic.
COP26 is now taking place in Glasgow between 31st October and 12th November 2021 and any decisions made could lead to big changes to our everyday lives.
So what is COP26 all about? Keep reading to find out.
COP stands for Conference of the Parties, and will be attended by countries that signed the United Nations Framework Convention on Climate Change (UNFCCC) - a treaty agreed in 1994.
The 2021 meeting will be the 26th meeting, which is why it's called COP26.
Why do we need COP?
The world is getting warmer because of fossil fuel emissions caused by humans.
Icecaps are melting and sea levels are rising.
We are seeing more extreme weather events taking place around the world - including heatwaves, floods and forest fires, these naturally occurring events are being made worse because of the effects of climate change.
The past decade was the warmest on record, and governments around the world agree that urgent action is needed.
People in poorer developing countries tend to pollute less and are not responsible for most of the emissions in the past but they experience some of the worst effects of climate change.
They need money to help reduce their emissions and also to cope with climate change. For example, it could mean more solar panels in countries that depend on energy from coal and flood defence systems.
The COP meeting in Madrid finished with lots of big issues unresolved, but an agreement was made about cutting carbon dioxide.
Each nation agreed to devise a plan to cut their carbon emissions by the next conference in Glasgow.
What is the Paris Agreement?
The Paris Agreement is a big international agreement to tackle climate change, which was agreed by leaders back in 2015 when 195 countries attended COP21 in Paris - hence the name.
However, there is still lots of debate about exactly how the agreed goals should be achieved.
COP26 will be biggest summit the UK has ever hosted. It is being described as the most significant climate event since the 2015 Paris Agreement.
Presidents and prime ministers from around the world will be reporting back on progress since the Paris Agreement and, hopefully, there will be some new decisions on how to cut carbon emissions.
Some commitments made in Glasgow could directly affect our daily lives.
For example, environmentalists say big changes to how people live will be needed to hit climate targets, like people driving electric cars, moving away from gas heating, eating less red meat and not taking as many flights in the future.
The UK government declared 2020 a "Year of Climate Action".
As well as the targets for changing to electric cars, the government has pledged to reduce the UK's carbon emissions to 'net zero' - which means cutting emissions drastically and absorbing as much carbon as it produces - by 2050.
This means emissions from areas like transport, farming and industry will have to be avoided completely or offset by sucking carbon dioxide out of the atmosphere.
This isn't technically Prime Minister Boris Johnson's idea - he inherited the pledge from the former prime minister Theresa May, who put the commitment into law in June 2019.
But Mr Johnson has said he wanted fighting climate change to be one of his government's biggest priorities and he has made a series of announcements around renewable energy, national parks and protecting the environment.
