lived warming pollutants would achieve a significant reduction in global warming over the next 50 - 100 years.

The boats produce other short -
lived pollutants, such as sulfur oxides and black carbon, which have cooling and
warming effects, respectively.
We could reduce short -
lived pollutants later, of course, but the inertia from CO2 - induced
warming means that those measures can only slow the rate of
warming, not reverse it and bring us back below 2 ̊C.

warming once we stop emitting short -
lived coal smoke and other
pollutants into the air and we give the Earth time to reach temperature equilibrium.
The Nature commentary by Penner et al. on which this argument is based actually says that on top of the global
warming caused by carbon dioxide, other short -
lived pollutants (such as methane and black carbon) cause an additional
warming approximately 65 % as much as CO2, and other short -
lived pollutants (such as aerosols) also cause some cooling.
The mitigation of Short -
lived Climate
Pollutants (SLCPs) has received much attention in the past few years for its potential to lessen health - related impacts of air pollution, prevent major crop losses, and in some cases also slow down global
warming.
There is growing recognition of the value of near - term actions to reduce short -
lived climate
pollutants (SLCPs) such as methane, black carbon, and various hydrofluorocarbons that have large global
warming potentials.
of Short -
lived Climate
Pollutants (SLCPs) has received much attention in the past few years for its potential to lessen health - related impacts of air pollution, prevent major crop losses, and in some cases also slow down global
warming.

warming driven only by carbon, ignoring short -
lived climate
pollutants, because of our emphasis on long - term commitment.
4.3 million of these deaths are due to 2.8 billion people in the developing world who cook and keep
warm inside their homes, by burning dung, firewood and coal — filling their
living spaces with smoke and
pollutants.
While diesels are the workhorses of the transport sector and relatively energy efficient (as compared to gasoline vehicles or jet aircrafts), their combined contribution to transportation - related climate
warming greenhouse gases and other short -
lived climate
pollutants, particularly black carbon, is significant.
Economists must offer convincing demonstrations of what is already apparent from the data: that modest
warming correlates with increased GNP, higher average income, and enhanced
living standards across the globe; and that carbon dioxide, rather than being a
pollutant, benefits the growth of agricultural crops and forests.

lived climate
pollutants and regional climate forcings, in addition to the impact of

While we must continue to aggressively reduce CO2 emissions, efforts to reduce short -
lived climate
pollutants like black carbon and methane can have an immediate effect on slowing
warming.

lived climate
pollutants [like methane] that we emit from human activities are basically controlling how fast the
warming occurs,» she said.
It discusses short
lived pollutants, some that may contribute to
warming, other that contribute to cooling.

A more accurate reading of the quote is that certain short -
lived pollutants cause
warming in addition to carbon dioxide - quantitatively, approximately 65 % as much
warming as CO2.
Unfortunately, reducing the short -
lived cooling
pollutants such as aerosols would cause a
warming effect of similar magnitude, and so CO2 remains the primary
pollutant of concern.
Although it is important to reduce the remaining climate uncertainties, such as the magnitude of the impacts of short -
lived pollutants, it does not change the fact that CO2 is very likely the driving force behind the current global

warm in the range of 2 to 4.5 °C.
