92 countries

Last updated 11/3/16

Goal of Paris Climate Agreement:

not allow earth to warm over 2 degrees Celsius/3.6 degrees Fahrenheit

26-28% below 2005 levels by 2025

Last updated 11/3/16

In 2018, the global ocean surface temperature averaged 1.19°F (0.66°C) above the 20th century average.

It is predicted that for every 1 degree Celsius increase in temperature, the equivalent of 190 million blue whales in carbon dioxide is released from the soil.

It is predicted that in order to avoid a 2 degree Celsius increase in temperature, greenhouse gas emissions will have to be cut by approx 10 billion tons per year by 2030.

Please note that some of these numbers are easier to find than others. These Global Warming stats are based on news reports and not official company tallies. No information contained on DMR should be relied upon to make investment decisions. Basically, this is the best I can find and I don’t guarantee anything to be 100%.
