We Are Counting Down To

A 2°C Global Warming Limit &

450 (ppm) of CO₂ in the Atmosphere

Carbon Dioxide avg ppm

At Today's Rate, 450 ppm will be reached by 2031

2°C is
A Goal Set in the 2015 UN Paris Climate Agreement,
To Keep the Increase in Global Average Surface Temperature Well Below 2 °C above pre-industrial levels

The Consequences of Inaction

< Impact of Sea Level Rise >

Severe Coastal Flooding Affecting Drinking Water & Farming
Submerged Coastal Cities
Contamination of Aquifers
Mass Migration of People
Social Instability & Conflicts.

< Impact of Ocean Warming & Acidification >

More Powerful Storms and Hurricanes
Massive Rainfall, i.e. Hurricanes Harvey & Irma
Death of Coral Around the World (Mass Die-Off, 90% by 2100)
Dissolving Shells in Shell-Forming Species
Tissue Damage & Necrosis in Fish Larvae & Damage to Internal Organs
The Decline of Fish Stocks Affecting a $100 Billion Annual Fishing Industry

< Other Potentially Disastrous Consequences >

Mega-Droughts lasting 20, 30, even 40 years
The loss of 50% of All Species as we enter the Sixth Mass Extinction.
Decreasing Surface Water Supply
Global Food Shortages, Then Famine
The release of CO₂ & Methane from Permafrost Melting.
The Eventual Collapse of West & East Antarctica Ice Sheets, Increasing Sea Levels Beyond Current Estimates.
Greenland's Melting reaching a tipping point potentially Adding 7 meters to Sea Level Rise.
Irreversible Climate Changes Beyond Our Control
