Question: What causes climate emergency?

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.

What is causing climate emergency?

Pollution. Air, water, land, light and noise pollution are major factors of the climate emergency. Burning fossil fuels pollutes the air we breathe as well as accelerating the climate emergency, and air pollution has been called the “new tobacco” by the World Health Organisation (WHO).
