Discover the science behind weather and climate
Get your climate change questions answered, take part in our national climate survey, and enjoy a range of weather and climate activities.
Climate and weather are two of the most talked about topics today. Politicians and scientists discuss climate change at length, and we are all too familiar with the devastating floods and hurricanes we see around the world.
OPAL scientists are working closely with the Met Office to raise awareness and understanding of weather and climate. You'll discover more about climate science, the important issues we face, and what action you can take.
Your climate questions answered
What is climate change and how do we know it is happening? Can we believe long-term forecasts?
The Met Office has answered as many of your climate change questions as possible. Take a look and read their responses.
The Met Office explains what we mean by climate.

Extreme weather - what happens when the weather turns ugly?
Flooding is mostly caused by a large amount of persistent rain or storm surges. Strong winds and low pressure create storm surges which result in large waves. The highest waves can sometimes break through or over coastal defences.
Drought occurs when there is a lack of rainfall over a long period of time. Droughts have a significant impact on agriculture and can harm the economy.
Hurricanes and typhoons are regionally-specific names for a strong tropical cyclone. A tropical cyclone is a low-pressure system over tropical or sub-tropical waters, with winds circulating either anti-clockwise (in the northern hemisphere) or clockwise (in the southern hemisphere).
Lightning is a large electrical spark caused by electrons moving from one place to another. Thunder is the sharp or rumbling sound that accompanies lightning. It is caused by the intense heating and expansion of the air along the path of the lightning.
