A Quote by Roy Spencer

Temperature measurements in the arctic suggest that it was just as warm there in the 1930's...before most greenhouse gas emissions. Don't you ever wonder whether sea ice concentrations back then were low, too?
We have no choice: we must protect Arctic ice, enable it to continue to act as an essential temperature regulator for the planet, avoid the catastrophic rise in sea levels that would result from the ice melt, and stop the disappearance of permafrost releasing irreversible quantities of greenhouse gases back into the atmosphere.
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.
When ships reduce their speed they use less fuel, resulting in fewer greenhouse gas emissions and other pollutants; the global shipping industry accounts for nearly 3 percent of global greenhouse gas emissions.
The simple fact is that, since the beginning of this century, the average global temperature has flatlined; indeed, over the past 18 months it has fallen back, and according to the satellite measurements of temperature, it is now basically back at the level it was in 1979, when such measurements started to be taken.
CO2 is a minor player in the total system, and human CO2 emissions are insignificant compared to total natural greenhouse gas emissions. Therefore, lowering human CO2 emissions will have no measurable effect on climate, and continued CO2 emissions will have little or no effect on future temperature....While controlling CO2 emissions from burning fossil fuels may have some beneficial effects on air quality, it will have no measurable effect on climate, but great detrimental effects on the economy and our standard of living.
Health care in the United States is responsible for a tremendous amount of waste and a significant amount of greenhouse gas emissions. For every hospital bed, the American health care system produces about 30 pounds of waste every day; over all, it accounts for about 10 percent of national greenhouse gas emissions.
The black line is carbon emissions to date. The red line is the status quo - a projection of where emissions will go if no new substantial policy is passed to restrain greenhouse gas emissions.
I taught world history. I understand there was an Ice Age... seasons come and seasons go. I do not believe the world's going to end because of the 2 percent man-made greenhouse gas emissions in the atmosphere. And even if it were, we're not going to stop it.
Greenhouse gas emissions: Ultimately, stabilisation - at whatever level - requires that annual emissions be brought down to more than 80% below current levels
Ice cores, which are long cylinders scientists extract from glaciers, ice sheets or ice caps, contain gas bubbles, pollen, dust particles, or chemical isotopes that give scientists clues about what Earth's temperature and atmosphere were like when the ice caps first formed.
'Scientific' computer simulations predict global warming based on increased greenhouse gas emissions over time. However, without water's contribution taken into account they omit the largest greenhouse gas from their equations. How can such egregious calculation errors be so blatantly ignored? This is why man-made global warming is 'junk' science.
Alongside energy efficiency, renewables and abatement, I believe safe nuclear power, with manageable waste, can play an important role in reducing greenhouse gas emissions, as long as it is cost competitive with other low carbon generation.
The best way to deal with climate change has been obvious for years: cut greenhouse-gas emissions severely. We haven't done that. In 2010, for example, carbon emissions rose by six per cent - the largest such increase on record.
In an agreement with China, President Obama has already pledged to reduce America's net greenhouse-gas emissions by more than 25% by 2025. In return, China has agreed to 'peak' its carbon-dioxide emissions in 2030.
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.
Those who deny human-caused climate change offer no compelling evidence to better explain the undeniable rise in atmospheric concentrations of greenhouse gases and global temperature.
