On October 6, 2018, the Intergovernmental Panel on Climate Change (IPCC) spelled out in plain, damning details what will happen if the Earth’s atmosphere warms by more than 1.5 degree Celsius.
The IPCC also provided a list of possibilities for policymakers, available at: http://report.ipcc.ch/sr15/pdf/sr15_spm_final.pdf
The David Suzuki Foundation has a thoughtful commentary on this important document:

No, it is not too late for us to change our course. However, we must resist the powerful forces that believe in the status quo. To quote an American author, Chris Hedges:
“Resistance is not only about battling the forces of darkness. It is about becoming a complete human being. It is about overcoming estrangement. it is about our neighbour.It is about honouring the sacred. It is about dignity. It is about sacrifice. It is about courage. It is about freedom. It is about the capacity to love. Resistance must become our vocation.”
