Limiting Warming to 1.5 °C Will Require Drastic Action, IPCC Says

Limiting Warming to 1.5 °C Will Require Drastic Action, IPCC Says

From Scientific American:

Humanity has a limited window to avoid the more dire effects of climate change, according to a new climate report

Limiting global warming to 1.5 °C above pre-industrial levels would be a herculean task, involving rapid, dramatic changes in how governments, industries and societies function, according to the Intergovernmental Panel on Climate Change (IPCC). But even though the world has already warmed by 1 °C, humanity has 10–30 more years than scientists previously thought in which to kick its carbon habit.

Given that current national commitments on greenhouse-gas emissions fall well short of the goals laid out in the Paris climate agreement, many scientists have argued that meeting even the 2 °C goal is virtually impossible. But the IPCC report sidestepped questions of feasibility and focused instead on determining what governments, businesses and individuals would need to do to meet the 1.5 °C goal.

Measures include ramping up installation of renewable energy systems such as wind and solar power to provide 70–85% of the world’s electricity by 2050, and expanding forests to increase their capacity to pull carbon dioxide from the atmosphere.

The world is on track for around 3 degrees of warming by the end of the century if it doesn’t make major reductions in greenhouse-gas emissions. It could breach 1.5 °C some time between 2030 and 2052 if global warming continues at its current rate.

Municipal Sustainability Checklist

We have created a municipal “sustainability checklist” that can help towns compare what they are doing with other towns, as well as get ideas and encourage collaboration. For residents, the checklist helps understand what towns are doing and not doing, as well as set priorities for local advocacy. For organizers, the checklist is an excellent tool to organize local groups around, and to build networks of people who care about sustainability.
