Food shortages and mass migration

Global average temperatures 1850 - 2017

Currently, global temperatures are around 1C above pre-industrial levels (since 1850) as shown in the graph. Source: Met Office There is only a 5% chance temperature rise will be as low as 2C. The likely range is between 2.9C and 5C. Source: Nature Climate Change 

These temperature rises will lead to horrendous consequences for children alive today. This should be on the news every night.

At around 3C, water will dry up in the Amazon rainforest and it will start to burn down. Source: The Guardian Forest fires will increase. Forests will become net producers of carbon, rather than the sinks they are today.

Global food security will be severely impacted. Crops will fail on a more regular basis, many areas will cease to produce food at all due to flooding or desertification. History shows that people suffer enormously when food prices spike.

As rising temperatures melt ice in Greenland and Antarctica, sea levels will rise, threatening populations living along the coast and in many towns and cities based on rivers. This is predicted to affect 10% of the UK population, including rural Lincolnshire, London, Edinburgh and many other places along the east coast. Some areas will be submerged forever, some will sustain severe damage. People will have to find new places to live in what remains of the country. 

Globally, when faced with the harsh impacts of climate change - devastating  droughts, floods, extreme weather, destruction of natural resources, famine and starvation - people will move. It is estimated that there will be up to 1 billion environmental migrants by 2050. Source: Inter Press Service
