Global Impacts

The global climate is already changing. The average world temperature has risen 0.6 over the last 100 years.

Global Impacts

Scientists calculate that the world’s temperature will rise between 1.4 and 5.8 degrees Celsius.

Global Impacts

A temperature rise of 1.4 degrees is predicted for scenario B2.Scenario B2 is people living in sustainable communities, with goods and services sourced locally.

Global Impacts

A temperature rise of 5.8 degrees is predicted for scenario A1. Scenario A1 is unrestricted world economic growth. Goods and services sourced globally.

Global Effects

Higher global temperatures means there is more energy available for the water cycle.

Global Effects

This means more water vapour can go into the atmosphere. When rainfall is then triggered, there is more water which can fall as rain or snow.

Global Impacts

Wind is caused by parts of the world having different temperatures. A warmer world will result in stronger winds. A warmer world’s climate is increasing the chance of severe weather.

Global Impacts

Some countries like the USA and Japan experience large storms during particular seasons. The frequency and strength of these storms is already increasing.

Global Impacts

As the world’s oceans warm they expand. Sea level is expected to rise by up to 1m over the next 100 years.

Global Impacts

Up to 250 million people world wide could be displaced by sea level rise alone

Global Impacts

At the same time many countries will experience long term droughts.

Global Impacts

There may be conflicts over resources and migration. Much of the world’s agricultural land could be damaged by flooding. Many crops may fail due to drought. There may be wars fought over food, water and energy.

Global Impacts

Glaciers are reducing in size. Many habitats are being lost and species are already becoming extinct.
