Not only has China recently become the world’s largest emitter of
greenhouse
gases, but the pace of its future emissions is expected to far exceed forecasts.
A breakthrough like this highlights one of the many ways in which ordinary people and businesses can reduce energy use and cut
greenhouse
gases.
Last year it also became the leading emitter of
greenhouse
gases.
In addition to adapting to climate change, the world must also reduce future risks to the planet by cutting back on emissions of
greenhouse
gases, which are the source of man-made climate change.
The effort to reduce
greenhouse
gases will require decades of action, but, given the long lead times in overhauling the world’s energy systems, we must start now.
It is ironic that the United States, which portrays itself as a friend of democracy and impoverished countries, gives the smallest share of its GNP in aid among the rich countries, and also refuses to participate in global efforts to reduce
greenhouse
gas emissions.
If Asian countries other than Japan commit to binding caps on
greenhouse
gas emissions, a global deal on climate change will be possible at this December’s Copenhagen Summit, even if developing Asia’s caps are implemented more gradually than those for the developed world.
Nature has the critical experimental data that we need to finally place Earth in context, within a zoo of worlds emerging from ice ages, worlds descending into
greenhouse
hells, young worlds, old worlds, barren worlds, and possibly worlds teeming with life.
Providing more people with access to electricity would have necessitated emitting more
greenhouse
gases, aggravating the consequences of climate change.
Testing the Limits of Fossil FuelsMILAN – Most people recognize that human activity, primarily the use of fossil fuels, is contributing mightily to an increasing level of
greenhouse
gases in the atmosphere.
Yet considerable uncertainty remains about the magnitude of the impact of rising levels of atmospheric
greenhouse
gases on temperatures and climate.
Despite the IPCC’s target for annual per capita CO2 emissions, we still do not know how much warming various levels of
greenhouse
gases in the atmosphere will cause.
Because combating climate change entails making decisions at different points over a long period of time, a key aspect to addressing the problem is to recognize that as stocks of
greenhouse
gases rise, we will learn more about the distribution of possible outcomes.
That can be changed by adding heat-trapping gases to the atmosphere – the so-called
greenhouse
gases, which absorb long-wave radiation on its way out and send some of it back towards the surface.
We know from measurements that
greenhouse
gases are accumulating in Earth’s atmosphere.
That is one of several reasons why hardly any serious climate scientist doubts that
greenhouse
gases are the cause of global warming.
The people wanting big slices are the countries that would like to emit large quantities of
greenhouse
gases.
For the atmosphere, that would mean calculating what quantity of
greenhouse
gases the world as a whole can safely emit up to a given date, and dividing that by the current population of the world.
That yields everyone’s per capita share of the atmosphere’s capacity to absorb our
greenhouse
gases, up to the selected date.
The US currently has less than 5% of the world’s population, but emits nearly 15% of the world’s
greenhouse
gases.
India, by contrast, has 17% of the world’s population and emits less than 6% of its
greenhouse
gases, so it would be entitled to almost three times its current emissions.
A different principle of fairness arises if we consider
greenhouse
gases as pollution, and apply the principle that whoever caused the pollution should pay to clean it up.
The reason that climate change is a problem now is that over the past two centuries, some countries have been putting large amounts of carbon dioxide and other
greenhouse
gases into the atmosphere.
No country has emitted more
greenhouse
gases over this period than the US.
That is a reason to require the US to make deeper cuts now than other countries must make, especially given that the US is continuing to emit
greenhouse
gases at a much higher per capita rate than other large emitters, such as China and India.
Other countries can claim that the US has already used up its historical per capita share of the atmosphere’s capacity to absorb
greenhouse
gases, and they should be entitled to emit more in the future so that we will at least come closer to equal per capita shares over time.
It makes no difference where
greenhouse
gases are emitted.
An academic paper published last year makes the point clear in its title: “Large-scale bioenergy from additional harvest of forest biomass is neither sustainable nor
greenhouse
gas neutral.”
For example, further warming would release large quantities of methane – a more potent
greenhouse
gas than carbon dioxide – from thawing Siberian permafrost, leading to more warming, more thawing, and more methane in the atmosphere.
The American Meteorological Society promptly wrote to Pruitt saying that it is “indisputable” that CO2 and other
greenhouse
gases are the primary cause of global warming, and that it is “not familiar with any scientific institution with relevant subject matter expertise that has reached a different conclusion.”
