What is the difference between climate and weather?

Weather changes day by day, hour by hour and sometimes minute by minute. When we talk about weather, we normally mean what is happening now, or in the next few days and weeks – is it going to be raining, sunny, windy or snowing today or this week? How warm will it be?

Climate describes the average weather over a much longer time – usually at least 30 years. By comparing today’s weather with the weather records from tens or even hundreds of years ago, scientists can spot changes in our climate more clearly.

Why is our climate changing?

By looking at the past, scientists can tell clearly that our climate has changed, especially over the last 100 years. It is warmer than it used to be, for example, and we have heavier rain at times than before.

Is our climate changing?

Scientists are sure that the changes in climate we have experienced over the past 100 years are being caused by an increase in these greenhouse gases. They are released as we burn fossil fuels (like coal, oil and gas) for energy, heat and transport, and through farming to make food. They trap more of the sun’s heat inside the earth’s atmosphere which is causing the planet to warm.

Surrounding our planet is a layer of gases, called the atmosphere. The earth’s atmosphere is mostly made of two gases, nitrogen and oxygen, but it also contains smaller amounts of other gases, sometimes called ‘greenhouse gases’. These include carbon dioxide and methane.

That warming is already changing weather and affecting the level of seas. In the future we expect to see:

  • Sun with a thermometer next to it showing a very high temperature

    Hotter summers and warmer winters

  • An umbrella with rain pouring on it

    Wetter winters, heavier rain and rising sea level

  • A green mountain with a small snow cap

    Less frost and snow

  • Dark rain clouds and lightning with a large puddle underneath

    Possibly stronger storms and extreme weather

Warmer weather might sound nice, but many of the changes we will see in the future will be harder to manage. Flooding and storms can damage buildings, water supplies can become scarce during really hot summers and animals and plants can struggle with the changes in the places where they live and grow.

What do we need to do?

You may feel a little anxious or scared when thinking about climate change, but the good news is that there are lots of things we can do to prepare and lots ways to help people, places and nature to prepare too.

  • Reducing our greenhouse gas emissions will reduce future climate change. This is sometimes called climate change mitigation. This is really important, and there are lots of ways you can personally help to reduce greenhouse gas emissions, like walking and cycling instead of going by car or by eating less meat to help reduce the amount of methane that is produced by animals that we eat. BUT…
  • The planet’s climate will continue warming until global greenhouse gas emissions fall to zero. This will take time even if we start making serious efforts now. SO…
  • We also need to get ready for climate change. This is called climate change adaptation. This is also really important, and the rest of this factsheet will give you some examples of what can be done.

Background

The information in this factsheet is part of the independent assessment for the third UK Climate Change Risk Assessment (CCRA3) led by the UK Climate Change Committee, who have worked with hundreds of experts in climate change. Find out more here.
