We need to get serious about both
a rapid decline in emissions and restoring our ecosystems to absorb more CO2 from the atmosphere.
Even if the accounting behind D.C.'s climate progress were trustworthy, it is highly unlikely that
the rapid decline in emissions will continue without substantive new policy interjections.
Just a quick note to those seeking
a rapid decline in emissions of greenhouse gases (and other pollution) from coal combustion: The challenge, in a world with rising populations and energy appetites, is getting harder by the day.
Not exact matches
A
rapid decline in annual
emissions would be needed to prevent warming from blowing past the ambitious temperature goals of the Paris agreement.
Central to these outcomes is the achievement of an early peak
in CO2
emissions and a subsequent
rapid decline, consistent with the Paris Agreement.
We also investigate,
in a Faster Transition Scenario, how policies could push an even more
rapid and steeper
decline in CO2
emissions and limit climate risks further.
While these and other studies give grounds to believe that very low
emissions pathways are not economically prohibitive, none model a short term (e.g., 2010 - 2020)
decline of CO2
emissions that is as
rapid as that postulated here or
in the Ackerman et al. scenarios, all of which have
emissions falling by more than 50 % between now and 2020.
The domestic mitigation effort is defined so as to match the
rapid decline needed to put the EU on course toward 90 % reductions relative to 1990 levels by 2050, consistent with the
emission trajectory for Annex I countries presented
in Figure 3 above.
In the opposite transition to rapid warming in 1975, once again I am struck by the fact that while aerosol emissions ceased to rise, they did not disappear entirely from the atmosphere, but began a gradual decline from a high pea
In the opposite transition to
rapid warming
in 1975, once again I am struck by the fact that while aerosol emissions ceased to rise, they did not disappear entirely from the atmosphere, but began a gradual decline from a high pea
in 1975, once again I am struck by the fact that while aerosol
emissions ceased to rise, they did not disappear entirely from the atmosphere, but began a gradual
decline from a high peak.
The choice is between leaving CO2
emissions to the markets with every expectation of large and
rapid decreases
in CO2
emissions or pursuing a government regulatory and subsidy approach that is unlikely to achieve anything except a bitter political and legal fight, rapidly increasing electricity rates, and rapidly
declining electricity reliability.
And for this the researchers have an explanation — and a funny way of expressing that: the drop from El Niño to La Niña, together with
declining solar insulation caused the cooling, because «
rapid growth
in short - lived sulphur
emissions partially offsets rising greenhouse gas concentrations» — thus creating a smaller net anthropogenic climate forcing.
Since the start of the twenty - first century, the researchers state, «the airborne fraction has been
declining (− 2.2 % per year), despite the
rapid increase
in anthropogenic
emissions.»
Declining solar insolation as part of a normal eleven - year cycle, and a cyclical change from an El Nino to a La Nina dominate our measure of anthropogenic effects because
rapid growth
in short - lived sulfur
emissions partially offsets rising greenhouse gas concentrations.
As mentioned above, much of the
decline in emissions is directly connected to the
rapid displacement of coal with natural gas power generation.
There are essentially two paths forward from here, both of them passing through Copenhagen and then heading on to a global peak and, subsequently, a
rapid decline in greenhouse - gas
emissions.
While this boom creates low unemployment and increased investment options (including real estate)
in many secondary and tertiary markets where drilling is prevalent, natural gas exploration is not without risk and cost, including increased carbon
emissions, groundwater contamination, reduced economic activity
in alternative energy sectors and the potential for boom - and - bust local economies susceptible to
rapid declines in production.
