Growing hemp as nature designed it is vital to our urgent need to reduce greenhouse gases and ensure the survival of our planet.
The clock is ticking as nature attempts to absorb the increased greenhouse gas emissions.
So if somebody wants to build a coal-powered plant, they can; it's just that it will bankrupt them because they're going to be charged a huge sum for all that greenhouse gas that's being emitted.
You could warm Mars up, over time, with greenhouse gases.
The basic scientific conclusions on climate change are very robust and for good reason. The greenhouse effect is simple science: greenhouse gases trap heat, and humans are emitting ever more greenhouse gases.
Meat is a wasteful use of water and creates a lot of greenhouse gases. It puts enormous pressure on the world's resources. A vegetarian diet is better.
Recent warming coincides with rapid growth of human-made greenhouse gases. The observed rapid warming gives urgency to discussions about how to slow greenhouse gas emissions.
China will soon emit more greenhouse gases than America, but its regime knows if it caps aspirations there will be a revolution.
If we are to meet the growing electricity demand in the United States without significantly increasing emissions of greenhouse gases, we must maintain a diverse supply of electricity, and nuclear power must be part of that mix.
Since stepping down as laboratory director in 1999, I have devoted an increasing fraction of my time to international issues. I am involved with energy, environment, and sustainability issues, particularly as they involve new energy sources free of greenhouse gases.
There are many who still do not believe that global warming is a problem at all. And it's no wonder: because they are the targets of a massive and well-organized campaign of disinformation lavishly funded by polluters who are determined to prevent any action to reduce the greenhouse gas emissions that cause global warming out of a fear that their profits might be affected if they had to stop dumping so much pollution into the atmosphere.
We can debate this or that aspect of climate change, but the reality is that most people now accept our climate is indeed subject to change as a result of greenhouse gas emissions.
August 28th 2012. Remember that date. It marks the day when the world went raving mad.
Factory farming is one of the biggest contributors to the most serious environmental problems. The meat industry causes more greenhouse gas emissions than all the cars, trucks, planes and ships in the world.
The international equity question arises from the costs of climate change itself and mitigation varying greatly across countries. It is affected by the historical responsibility for current greenhouse gas emissions, which countries which were not responsible for what's in the atmosphere now think are very important. Currently rich countries don't think those issues are very important.
Under my plan of a cap and trade system, electricity rates would necessarily skyrocket… Because I’m capping greenhouse gasses, coal power plants, natural gas…you name it…whatever the plants were, whatever the industry was, they would have to retro-fit their operations. That will cost money…they will pass that money on to the consumers.
It is a simple fact of life on earth that there is going to be no successful mitigation of the climate change problem without a truly global effort. All developing companies or all major developing countries have to be part of that and accept substantial constraints on greenhouse gas emissions.
Is there some thought being given to subsidizing the clearing of rainforests in order for some countries to eliminate that production of greenhouse gases?
There is not going to be, we can be quite certain, there's not going to be any action on reducing greenhouse gas emissions by China or India or Indonesia or Brazil unless all developed countries are making a major effort. It will still be a big job to get them in, even if we are all making the effort. But our making the effort is a necessary condition.
If Africa is left behind, she is going to continue pumping greenhouse gases into the atmosphere, especially carbon. She's going to continue logging the forests, she's going to continue burning charcoal, she is going to continue practicing agricultural activities that destroy the environment, and sooner or later Africa's problem will become a global problem.
Under my plan of a cap-and-trade system, electricity rates would necessarily skyrocket.
Greenhouse gas pollution, through its contribution to global climate change, presents a significant threat to Americans health and to the environment upon which our economy and security depends.
I'm totally in favour of meeting our Paris commitments to reduce greenhouse gas emissions. But I don't think we should do that by making ourselves uncompetitive.
A vegan riding a hummer contributes less to greenhouse gas emissions than a meat eater riding a bicycle.
...the global surface albedo [surface whiteness] and greenhouse gas changes account for practically the entire global climate change.
