The scientific consensus is clear. The world confronts an urgent carbon problem. The carbon in our atmosphere has created a blanket of gas that traps heat and is changing the world’s climate.
Already, the planet’s temperature has risen by 1 degree centigrade. If we don’t curb emissions, and temperatures continue to climb, science tells us that the results will be catastrophic.
As the scientific community has concluded, human activity has released more than 2 trillion metric tons of greenhouse gases into the Earth’s atmosphere since the start of the First Industrial Revolution in the mid-1700s. Over three-quarters of this is carbon dioxide, with most of this carbon emitted since the mid-1950s. This is more carbon than nature can re-absorb, and every year humanity pumps more than 50 billion metric tons of additional greenhouse gases into the air. This isn’t a problem that lasts a few years or even a decade. Once excess carbon enters the atmosphere it can take thousands of years to dissipate.
The world’s climate experts agree that the world must take urgent action to bring down emissions. Ultimately, we must reach “net zero” emissions, meaning that humanity must remove as much carbon as it emits each year. This will take aggressive approaches, new technology that doesn’t exist today, and innovative public policy. It is an ambitious – even audacious – goal, but science tells us that it’s a goal of fundamental importance to every person alive today and for every generation to follow.
