If you care about the future of life on Earth, there's some
you should know.
Atmospheric CO2 concentrations just passed 400 parts per million.
The world's most important CO2 monitoring station is recording short term CO2 concentrations above 400 parts per million
-- the highest levels found on earth in millions of years. Already we're seeing the deadly effects of climate change in the form of rising seas, wildfires and extreme weather of all kinds, and passing 400 PPM is an ominous sign of what might come next.
The safe level of carbon dioxide in the atmostphere is 350 parts per million
, but the only way to get there is to immediately transition the global economy away from fossil fuels and into into renewable energy, energy efficiency, and sustainable farming practices in all sectors (agriculture, transport, manufacturing, etc.). While the level fluctuates seasonally and varies across different latitudes, this is yet another sign that our dependence on fossil fuels is out of control.
What this means
"We're in new territory for human beings--it's been millions of years since there's been this much carbon in the atmosphere. The only question now is whether the relentless rise in carbon can be matched by a relentless rise in the activism necessary to stop it."
Dr. James Hansen
Former NASA Climatologist
"If humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO2 will need to be reduced ... to at most 350 ppm."
Coordinator, Global Power Shift
Crossing the 400 ppm threshold is a somber reminder that we haven't taken the action we need. Nevertheless there is good reason for hope -- activists all across the globe are fighting the fossil fuel industry and demanding clean, just and affordable solutions to our energy needs. At Global Power Shift, a convergence in Istanbul this June, 500 mostly young climate activists from 135 countries will come together to plan a global strategy for change. Upon returning home they'll escalate action and create the global power shift our world needs to push for 350 ppm.
West Coast Fossil Free Organizer
My grandmother said that we are always walking toward our goals or away from them. As we reach 400PPM I am thinking about her, and wondering which way the the Board of Trustees from any of the 40 fossil free campus campaigns I work with are walking. Perhaps, this will be the moment we decided to walk toward our common goals, to treat each moment as a chance to invest in our future. That's what my grandmother would hope, that's what I hope, that's what students are fighting for now.
400 ppm in the news
This is an important moment in human history. Here's what news sources across the globe are saying about 400 PPM:
What people are saying
Tweets about "#400ppm OR #350PPM OR "400 PPM" OR @Keeling_curve OR "350 PPM""
350 parts per million = safe level of carbon in the atmosphere.
And the namesake for the 350 movement. This explains what's it's all about:
What We're Doing About It
We've got work to do, and there's not a moment to lose.
Global Power Shift
A Global Convergence For Climate Action
Phase 1: Istanbul, Turkey Phase 2: Everywhere
Global Power Shift is the starting point for a new phase in the international climate movement. First, hundreds of climate leaders from around the world will gather in Istanbul to launch a year of new strategy and action for the movement. Then, we will fan out across the globe to spark an unprecedented wave of events and mobilizations for climate action. globalpowershift.org
A movement to divest schools, religious institutions and governments from fossil fuels.
400+ communities everywhere
The fossil fuel industry is planning to burn 5 times more carbon than the planet can afford -- and we're financing it. That's why people everywhere are organizing to demand their communities divest from destruction by taking their money out of fossil fuels. If it's wrong to wreck the planet, it's wrong to profit from that wreckage. gofossilfree.org
Stop the Keystone XL tar sands pipeline
Telling President Barack Obama to keep his promises and stop the pipeline
USA and Canada
The Keystone XL tar sands pipeline would transport 800,000 barrels a day of the world's dirtiest oil from Canada to the Gulf Coast -- we're joining with people across the US and Canada to let the President know he needs to live up to his lofty climate rhetoric and stop the pipeline. 350.org/KXL
