A Quote by John Christy
...it is fairly well agreed that the surface temperature will rise about 1°C as a modest response to a doubling of atmospheric CO2 if the rest of the component processes of the climate system remain independent of this response.

Each year we pump at least six billion tons of heat-trapping carbon into the innermost layer of our atmosphere, whose outer extent is only about twelve miles overhead. According to an IPCC (United Nations' Intergovernmental Panel on Climate Change) report released this year, atmospheric CO2 will, if the buildup is left unchecked, double from its pre-industrial level within the next century. That doubling of CO2 correlates with an increase in the global temperature of at least three to eight degrees Fahrenheit. The last ice age was just five to nine degrees colder than our current climate.
... For nearly a decade now, there has been no global warming. Even though atmospheric CO2 has continued to accumulate - up about 4 percent in the last 10 years - the global mean temperature has remained flat. That should raise obvious questions about CO2 being the cause of climate change.
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.
The atmospheric CO2 concentration is rising - mainly due to the burning of fossil fuels. It's agreed that this build-up will, in itself, induce a long-term warming trend, superimposed on all the other complicated effects that make climate fluctuate.
When we're talking about the "American response" to any disaster, it's not just a government response, an official response, it's a popular response.
We can no longer completely avoid anthropogenic climate change. At best, limiting the temperature rise to two degrees is just about possible, according to optimistic estimates. That's why we should spend more time talking about adjusting to the inevitable and not about reducing CO2 emissions. We have to take away people's fear of climate change.
The climate system is constantly readjusting naturally in a large way - more than we would ever see from CO2. The CO2 kick [impact of CO2 emissions] is extremely small compared to what is happening in a natural way. Within the framework of a proper study of the sun-climate connection, you don't need CO2 to explain anything.
These proven positive consequences of elevated CO2 are infinitely more important than the unsubstantiated predictions of apocalypse that are hypothesized to result from global warming, which itself, may not be occurring from rising atmospheric CO2 levels. The aerial fertilization effect of atmospheric CO2 enrichment is the only aspect of global environmental change about which we can be certain; and to restrict CO2 emissions is to assuredly deny the biosphere the many benefits that accrue from this phenomenon.
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.
... The reality is that atmospheric CO2 has a minimal impact on greenhouse gases and world temperature. Water vapor is responsible for 95 percent of the greenhouse effect. CO2 contributes just 3.6 percent, with human activity responsible for only 3.2 percent of that. That is why some studies claim CO2 levels are largely irrelevant to global warming.
CO2 emissions have been increasing, but the rise in air temperature stopped around 2001. Climate change is due in large part to naturally occurring oscillations.
When you vaccinate someone, or when you get infected, the microbe is presenting itself to the immune system in a way that the immune system recognizes the important elements of the microbe and makes an immune response, both an antibody response and a cellular response, to ultimately contain the microbe.
Putting aside for the moment the question of whether human industrial CO2 emissions are having an effect on climate, it is quite clear that they are raising atmospheric CO2 levels. As a result, they are having a strong and markedly positive effect on plant growth worldwide. There is no doubt about this.
Climate scientists think of nothing but climate and then express their concerns in terms of constructs such as global mean surface temperature. But we live in a world in which all sorts of change is happening all the time, and the only way to understand what climate change will bring is to tell stories about how it manifests in people's lives.
Acceptance is not a talent you either have or don't have. It's a learned response. My meditation teacher made a great point about the difference between a reaction and a response: You may not have control over your initial reaction to something, but you can decide what your response will be. You don't have to be at the mercy of your emotions, and acceptance can be your first step toward empowerment . . . For me, acceptance has been the cornerstone to my having an emotionally healthy response to my illness.
Your mind, in order to defend itself starts to give life to inanimate objects. When that happens it solves the problem of stimulus and response because literally if you're by yourself you lose the element of stimulus and response. Somebody asks a question, you give a response. So, when you lose the stimulus and response, what I connected to is that you actually create all the stimulus and response.
