There is a climate emergency because our climate is changing faster than nature can adapt to it, including us. We have a limited time to keep global temperatures within a limit that the earth can recover from, so we have to take action now.
The climate is the long-term pattern of day to day weather. Put simply, the climate is what you have in your wardrobe whereas the weather is what you are wearing today.
Our food and water supplies depend on stable seasonal patterns of temperature, rain, and wind in the UK and elsewhere. In the last 100 years, the earth’s average temperature has increased faster than previously seen – this is known as global warming or global heating. This global heating of the planet is causing our climate to change.
Evidence shows that human activity and our use of fuels like petrol, diesel, gas, and coal is highly likely to be the main cause of global warming. When these fuels are burned they release greenhouse gases which trap heat in the earth’s atmosphere, causing the air and seas to heat up which changes the climate. The greenhouse gases produced when we burn these fuels contain a lot of carbon and so the term ‘carbon emissions’ is often used.
The problem is that current levels of greenhouse gases are higher than they have been over the last 800,000 years and they are rising rapidly, causing the climate to change more rapidly than life and weather systems can adapt to.
