We are at risk of pushing our climate system toward abrupt, unpredictable, and potentially irreversible changes with highly damaging impacts. Earth’s climate is on a path to warm beyond the range of what has been experienced over the past millions of years. The range of uncertainty for the warming along the current emissions path is wide enough to encompass massively disruptive consequences to societies and ecosystems: as global temperatures rise, there is a real risk, however small, that one or more critical parts of the Earth’s climate system will experience abrupt, unpredictable and potentially irreversible changes. Disturbingly, scientists do not know how much warming is required to trigger such changes to the climate system.

So what does the world do? The problem is with the oligarchs who caused this to happen and continue to pretend this isn't happening:
...we cannot save ourselves without contesting oligarchic control, the fight for democracy and justice and the fight against environmental breakdown are one and the same. Do not allow those who have caused this crisis to define the limits of political action. Do not allow those whose magical thinking got us into this mess to tell us what can and cannot be done.
The proletariat is starting to rise up against the oligarchs and the systems they control:
The Earth Strike movement has formed a plan of action spanning 2019 with four primary international events. Local organizers are encouraged to take any opportunities their groups have to get protesters on the streets or at local events to gain more attention for the movement.
January 15, 2019 – Earth Strike Kickoff Protest, the first world-wide event will allow all our national and local organizers to engage their communities and begin the process of organizing groups of people on the ground to see the movement through to the strike.
April 27, 2019 – Halfway Earth Day Protest, which will be held in the weekend after Earth Day, to symbolize the halfway mark to the Earth Strike. Organizers and protesters will use the build-up to May Day to form closer ties with local unions who will be integral to gathering yet more widespread support for the strike.
August 1, 2019 – Final Pre-Strike Protest, held on the Earth Overshoot Day of 2018. A final protest just before the strike, to serve as a final wake-up call for those that have not yet joined in.
September 27, 2019 – Earth Strike! On the 57th anniversary of Silent Spring, the book that kick-started the environmentalist movement, we will hold the General Strike to Save the Planet, or the Silent Spring Strike!
