Why? Because we care…
We care about the Earth - and we believe it's up to all of us to protect it. The problem is, our planet's vital signs are changing at a rapid rate. It's time for urgent action, before it's too late.
Here's why you should care too
Check out these facts about our planet's health
Carbon dioxide (CO2) is an important heat-trapping (greenhouse) gas, which is released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as respiration and volcanic eruptions.
The graph shows CO2 levels during the last three glacial cycles, as reconstructed from ice cores. As you can see, this is far from a 'normal' cycle.
17 of the 18 warmest years in the 136-year record all have occurred since 2001, with the exception of 1998.
This graph illustrates the change in global surface temperature relative to 1951-1980 average temperatures.
Arctic Sea Ice Minimum
Arctic sea ice reaches its minimum each September. September Arctic sea ice is now declining at a rate of 13.2 percent per decade, relative to the 1981 to 2010 average.
This graph shows the average monthly Arctic sea ice extent each September since 1979, derived from satellite observations.
Data from NASA's GRACE satellites show that the land ice sheets in Antarctica has been losing mass since 2002. The ice sheet has seen an acceleration of ice mass loss since 2009.
Sea level rise is caused primarily by two factors related to global warming: the added water from melting ice sheets and glaciers and the expansion of sea water as it warms.
The graph tracks the change in sea level since 1993 as observed by satellites.
