A Quote by Alan Lowenthal
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.

Adaptation can efficiently reduce the costs of climate change while atmospheric concentrations of greenhouse gases are being stabilised
... 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.
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.
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).
We seriously have to question the motivation of those people referred to as climate change sceptics, who are denying the evidence of human-caused climate change and preventing us from moving forward by spreading disinformation and supporting unchecked carbon pollution.
The models that have been constructed agree that when, as has been predicted, the level of carbon dioxide or its equivalent in other greenhouse gases doubles from pre-Industrial Revolution concentrations, the global average temperature will increase, and that the increase will be 1.5 to 4.5 degrees Celsius or 3 to 8 degrees Fahrenheit... In Dallas, for instance, a doubled level of carbon dioxide and other gases like methane, would increase the number of days a year with temperatures above 100 degrees from 19 to 78 each year.
Climate change is the world's greatest environmental challenge. It is now plain that the emission of greenhouse gases, associated with industrialization and economic growth...is causing global warming at a rate that is unsustainable.
I am not a global warming sceptic. I accept that rising human-caused CO2 from fossil sources could 'change the climate'. The basic physics is there to support this view. But where is the evidence that the putative change would be large or damaging?
The climate's sensitivity to greenhouse gases is considerably lower than the Intergovernmental Panel on Climate Change claims - so much lower, in fact, that the warming we would expect from doubling the amount of carbon dioxide in the atmosphere would be quite modest and offer very little risk.
... 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.
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.
... 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.
The basic science is very well established; it is well understood that global warming is due to greenhouse gases. What is uncertain is projections about specifics in the next few decades, by how much will the climate change.
Most challenges arise suddenly, with little warning. Climate change is different. For decades, we've known why global average temperatures are rising, why greenhouse gas concentrations are increasing, why the oceans are warming and weather patterns are growing more extreme.
While the ranking of individual years can be affected by chaotic weather patterns, the long-term trends are attributable to drivers of climate change that right now are dominated by human emissions of greenhouse gases...
If the relatively rich participating countries want to stabilize atmospheric concentrations of greenhouse gases, they will have to pay at least some poor countries to reduce their emissions. Achievement of substantial reduction in this way implies international transfers of wealth on a scale well beyond anything in recorded history. There is no effective political support for such a Herculean effort, particularly in the United States.
