I honestly don't know, but if America continues to refuse to reduce its greenhouse gas emissions, I see a bleak future not only for American society, but for the world as a whole. This is a global problem that is not going away, and the United States is an obstacle to solving it.
Even if we didn't have greenhouse gases, were going to have to move away from fossil fuels, as we're going to run out. They're finite, whereas solar and wind are infinite.
I do not believe we can effectively move Australia to a lower emission economy, which is what we need to do if we're going to make a contribution to a global reduction in greenhouse gases, without putting a price on carbon.
The human race likes to give itself airs. One good volcano can produce more greenhouse gases in a year than the human race has in its entire history.
Global warming results not from the emission of greenhouse gases into the atmosphere, but from an unusually high level of solar radiation and a lengthy - almost throughout the last century - growth in its intensity. It is no secret that when they go up, temperatures in the world's oceans trigger the emission of large amounts of carbon dioxide into the atmosphere. So the common view that man's industrial activity is a deciding factor in global warming has emerged from a misinterpretation of cause and effect relations.
Concentration of greenhouse gases, especially CO2, have increased substantially since the beginning of the industrial revolution. And the National Academy of Sciences indicates that the increase is due in large part to human activity.
Look, any cut in greenhouse gases is going to be expensive for American consumers, who are in no mood to bear additional costs.
...the contribution of greenhouse gases to the Vostok temperature changes can be...between a lower estimate of 40% and a higher estimate of 65%.
The US is responsible for 25 percent of the world's greenhouse gas emissions. It should take responsibility for leading the way.
India was a late comer to industrialization, and as such, we have contributed very little to the accumulation of greenhouse gas emissions that cause global warming. But we are determined to be part of the solution to the problem.
I am troubled by the lack of common sense regarding carbon dioxide emissions. Our greatest greenhouse gas is water. Atmospheric spectroscopy reveals why water has a 95 percent and CO2 a 3.6 percent contribution to the 'greenhouse effect.' Carbon dioxide emissions worldwide each year total 3.2 billion tons. That equals about 0.0168 percent of the atmosphere's CO2 concentration of about 19 trillion tons. This results in a 0.00064 percent increase in the absorption of the sun's radiation. This is an insignificantly small number.
Are global temperatures rising? Surely, they were rising from the late 1970s to 1998, but 'there has been no net global warming since 1998.' Indeed, the more recent numbers show that there is now evidence of significant cooling [...] Mankind is responsible for just a fraction of one percent of the effect from greenhouse gases, and greenhouse gases are not responsible for most of what causes warming (e.g., the Sun).
Adaptation can efficiently reduce the costs of climate change while atmospheric concentrations of greenhouse gases are being stabilised
...99 percent confident that the world really was getting warmer and that there was a high degree of probability that it was due to human-made greenhouse gases.
It's very important that we expand our use of clean energy and make a long-term commitment to it. Biodiesel and ethanol are better for the environment and for the air we breathe. The use of biodiesel is a positive step toward minimizing pollutive emissions and greenhouse gases. By focusing on school buses, we can affect the health and wellbeing of the people most susceptible to that pollution - our children - today.
There is a natural greenhouse effect that contributes to warming. Greenhouse gases trap heat and thus warm the Earth because they prevent a significant portion of infrared radiation from escaping into space.
Researchers at the Naval Postgraduate School have told us that the entire Arctic ice cap may totally disappear in summer in as little as five years if nothing is done to curb emissions of greenhouse gas pollution.
Extreme weather like the droughts in Russia, China and Brazil and the flooding in Pakistan and Australia [in 2010] have contributed to a level of food price volatility we haven't seen since the oil crisisof 40 years ago. Unfortunately, this could be just a taste of things to come because in the next few decades the build-up of greenhouse gases already in the atmosphere could greatly increase the risk of droughts, flooding, pest infestation and water scarcity for agriculture systems already under tremendous stress.
... the consensus of the scientific community has shifted from skepticism to near-unanimous acceptance of the evidence of an artificial greenhouse effect. Second, while artificial climate change may have some beneficial effects, the odds are we're not going to like it. Third, reducing emissions of greenhouse gases may turn out to be much more practical and affordable than currently assumed.
Many of our actions degrade our habitat because we undertake them in order to reach goals whose allure blinds us to myriad dire consequences. In order to fuel our complex civilizations, we are lacing our planet's atmosphere with carbon dioxide, a greenhouse gas that, if it has not already begun doing so, will soon warm the Ice Age climate to which we owe our very existence.
Because of the inherent time lag in the climate system, the greenhouse gases that have already been pumped into the atmosphere will undoubtedly lead to a certain increase in temperature in the coming decades.
If the US is the country that most contributes with greenhouse gases, in the world, it should assume more responsibility to reduce emissions
People have not made the connection that the more of us there are, the more greenhouse gases go into the atmosphere. The Chinese have. They, unlike us, have a population policy. The right wingers just don't understand that the country they're in is probably the most overpopulated in the world, the one doing most of the destruction, and the one with horrendously bad leadership.
The Kyoto Treaty wasn't perfect, but we signed it, in fact, helped to draft it. And I'm very proud of it, it was the world's first commitment to doing something comprehensive on greenhouse gases and trying to reduce global warming before we do irreversible damage to many civilizations around the world.
Even if we were to stop putting out greenhouse gases right now, we'd still face decades of warming.
