The world is getting warmer

The average temperature of the Earth’s surface has increased by about 0.85°C (1.4F) in the last 100 years.
Thirteen of the 14 warmest years were recorded in the 21st Century, with 2015 on course to set another record.

Why is this happening?

We are burning fossil fuels like coal, oil and natural gas.
Carbon-absorbing forests are also being cut down.
The concentration of CO2 in the atmosphere is now higher than at any time in the last 800,000 years and reached a record high in May this year.

Reasons for studying Climate change

Climate can be thought of as the average or typical weather conditions we experience. Scientists know that climate varies naturally on many timescales and they know that people are affecting climate – particularly through emissions of greenhouse gases.

What does the future hold?

-Shortages in freshwater

-Rise in the number of casualties from floods, storms, heat waves and droughts.

-Poor countries would suffer the most.
