| Zusammenfassung |
| There is growing international interest in mitigating climate change during
the early part of this century by reducing emissions of short-lived climate
pollutants (SLCPs), in addition to reducing emissions of CO2. The SLCPs
include methane (CH4), black carbon aerosols (BC), tropospheric ozone
(O3) and hydrofluorocarbons (HFCs). Recent studies have estimated that
by mitigating emissions of CH4, BC, and O3 using available
technologies, about 0.5 to 0.6 °C warming can be avoided by
mid-21st century. Here we show that avoiding production and use of high-GWP
(global warming potential) HFCs by using technologically feasible low-GWP
substitutes to meet the increasing global demand can avoid as much as
another 0.5 °C warming by the end of the century. This combined
mitigation of SLCPs would cut the cumulative warming since 2005 by 50% at
2050 and by 60% at 2100 from the CO2-only mitigation scenarios,
significantly reducing the rate of warming and lowering the probability of
exceeding the 2 °C warming threshold during this century. |
