SIX DEGREES

See what each degree of global warming means for the chances of humans and animals surviving.

The poster "Six degrees" is based on the award-winning science journalist Mark Lynas' latest book: "Our final warning: Six degrees of climate emergency".

#AllForClimate: Six degrees

We are facing a climate emergency posing an existential threat to humanity. The crisis requires “rapid, far-reaching and unprecedented changes in all aspects of society”, says the UN’s IPCC. If we want to ensure good living conditions for all, within the limits of the planet, we must redefine what living well means, and create an economy that does not depend on growth.
We have been waiting too long for others to solve the crisis. But all actors in society have important roles to play in the transition ahead. All of us, individuals and organisations, must realise that we are part of the problem and must act boldly now to become part of the solution. This is the core of the #AllForClimate campaign.
Despite the progress made by science, we do not know for sure when tipping points will be triggered, and when global warming could be unstoppable. For any tenth of a degree of global warming we let happen, we are gambling with a future that, in the worst case, none of us can survive.

+0°C

THE WORLD BEFORE INDUSTRIALISATION

The temperature reached on Earth around 11,000 years ago after the last ice age. Ice melting made the sea level rise about 120 metres. Stable and mild climate allowed humans to grow food and settle down. Cities aroused, consumption was low and living ways mostly sustainable. Humans were already affecting their environment, but not so much the world’s climate.

+1°C

WE ARE GAMBLING WITH OUR FUTURE

In 2015, global warming reached 1°C above pre-industrial levels. Six years later it reached 1.1°C. The Arctic and Antarctica are melting. The Gulf Stream is weakening. Glaciers are melting affecting freshwater supply. Hurricanes, droughts, heatwaves and large wildfires are more frequent. Low-lying coastlines are flooded. Ice-free sea absorbs more heat and accelerates global warming. Corals are bleaching. Wildlife is in decline. Food production is starting to be affected.

A PRESCRIPTION FOR LONG-TERM DISASTER

Climate breakdown. Ice-free summertime in the Arctic. Irreversible loss of the West Antarctic Ice Sheet. 80 million people displaced due to sea-level rise. Deadly dengue fever. About half a million die of malnutrition. Insect crops pests. Hundreds of millions exposed to deadly heat. Shortage of water in Africa. Mass migration. Loss of glaciers affects freshwater supply. More floods.  Conflagration of the Amazon rainforest. Many species are threatened. 99% of reef-building corals are lost.

+3°C

VEGETATION EMIT CARBON AND SPEED WARMING

Ice sheets and glaciers partly collapse. Sea-level rises to 8-14 metres. Extreme high tides, floods, superstorms and super-hurricanes. Hundreds of millions of people are forced to relocate. Half the world’s population is annually exposed to deadly heat waves. Invading deserts. Food production cut by half. Mass starvation. Death of the Amazon rainforest. Increased wildfires. Wildlife disruption. Carbon release from vegetation and soils speeds global warming, so does methane emissions from melting permafrost.

+4°C

GLOBAL WARMING IS UNSTOPPABLE

Three-quarters of the global population is exposed to deadly heat in days. Substantial areas of the planet are biologically uninhabitable for humans. Climate refugee numbers become unmanageable.  Half the world’s land surface becomes ‘arid’. Extreme droughts and floods. Category 6 super-hurricanes. Synchronous failures of major world food crops. Potential ice-free planetary state. Mass extinction. Permafrost meltdown makes the escalation of global warming unstoppable. Civilisation is tottering or collapsing.

+5°C

SURVIVING HUMANS LIVE LIKE ANIMALS

Ice sheet is permanently gone. Humans can no longer survive outside for a long time. Food production is decimated. Complex human societies have collapsed. Global famine. Surviving humans try vainly to live like animals off the land.

+6°C

ONLY FEW ANIMALS AND FUNGI SURVIVE

Extreme greenhouse effect destroys most of life on Earth. Only a few animals can survive. Ecosystems and food webs cease to exist in any functional sense. The big winners are detritivores, bacteria and fungi.
