gas is carbon dioxide.
Twenty years ago, the world agreed to reduce sharply emissions of CO2 and other
greenhouse
gases, but little progress has been made.
Climate research dates back at least two centuries, to Joseph Fourier’s discovery of the effects of
greenhouse
gases on planetary climates; in 1859, John Tyndall demonstrated in his laboratory which gases cause this effect.
Detailed radiation measurements on the ground and from satellites have since proved the
greenhouse
effect’s existence.
We also know beyond doubt that emissions from human activities have substantially increased the amount of
greenhouse
gases (especially carbon dioxide) in our atmosphere.
We know that the amount of
greenhouse
gases is rising due to our emissions, and we know that this is causing warming.
We should be open to other ways to stop warming – such as cutting carbon emissions in the future instead of now, or focusing on reducing emissions of other
greenhouse
gases.
Professor Brent Sohngen of Ohio State University points out that forests could be important: including forestry in the control of
greenhouse
gases could somewhat reduce costs.
It will be difficult for the world to achieve the twin goals of ensuring sustainable energy supplies and curbing

greenhouse
gases to the United States and Europe in return for development aid.
The choices, singly or in combination, are: 1) nothing (the current response); 2) mitigation (reducing emissions of
greenhouse
gases); 3) attempted adaptation to the ongoing climate changes; and 4) geoengineering.
Population, exposure, and vulnerability, not
greenhouse
gasses, are the main factors underlying future damage as well.
This puts a new debate center stage: how to reconcile increased action to reduce
greenhouse
gas emissions with strong economic growth.
It has surpassed the United States as the world’s largest source of
greenhouse
gases, and it became developing nations’ diplomatic champion at the recent United Nations climate negotiations in Bali.
The focus on China intensified late last year, when new data from the International Energy Agency and other research organizations revealed that China had overtaken the US as the largest source of
greenhouse
gases – and, more ominously, that its emissions are growing at a rate that exceeds all wealthy nations’ capacity to decrease theirs.
In response, the US Congress is moving to create a system of trade sanctions that would levy heavy taxes on imports from other major
greenhouse
gas emitters.
Despite China’s official hard line, some Chinese environmental officials privately express alarm at run-away carbon emissions, and suggest that foreign green tariffs would actually strengthen their hand in domestic policy struggles over controlling
greenhouse
gases by helping to win political support for emissions cuts.
Earlier conferences of the UNFCCC signatories sought to reach legally binding agreements on emission reductions, at least for the industrialized countries that have produced most of the
greenhouse
gases now in the atmosphere.
Studies ahead of the Paris conference suggest that international cooperation could allow for rapid reduction of
greenhouse
gases.
Every citizen in the world would have the same right to emit
greenhouse
gas, and every country would face the same incentives at the margin to reduce emissions.
But, as the British newspaper The Guardian assured readers, this was a breakthrough, because developing countries, including India and China, were, for the first time, “agreeing to be legally bound to curb their
greenhouse
gases.”
