Twelve More Years To Do Nothing

Human activities are estimated to have caused approximately 1.0°C of global warming above pre-industrial levels with a likely range of 0.8°C to 1.2°C. Global warming is likely to reach 1.5°C between 2030 and 2052 if it continues to increase at the current rate (high confidence). — IPCC

The magnitude of the changes in climate effects that would be produced by the least stringent action alternative (Alternative 1) by the year 2100 is roughly a 0.6 ppm higher concentration of CO2, three thousandths of a degree increase in temperature rise, a small percentage change in the rate of precipitation increase, about 0.06 centimeter (0.02 inch) of sea-level rise, and an increase of 0.0004 in ocean pH.— NHTSA

Avoiding overshoot and reliance on future large-scale deployment of carbon dioxide removal can only be achieved if global CO2 emissions start to decline well before 2030 (high confidence) — IPCC

Alternative 7, the lowest CO2 emissions alternative, would result in CO2 concentrations of 687.4 ppm, an increase of 0.15 ppm compared with the No Action Alternative. — NHTSA

The warming from the pre-industrial period to the present will persist for centuries to millennia and will continue to cause further long-term changes in the climate system, such as sea-level rise, with associated impacts (high confidence)….


Pathways limiting global warming to 1.5°C with no or limited overshoot would require rapid and far-reaching transitions in energy, land, urban and infrastructure (including transport and buildings), and industrial systems (high confidence). These systems transitions are unprecedented in terms of scale, but not necessarily in terms of speed, and imply deep emissions reductions in all sectors, a wide portfolio of mitigation options and a significant upscaling of investments in those options (medium confidence).— IPCC
