Be worried. Be very worried. ...Pump enough CO2 into the sky, and that last part per million of greenhouse gas behaves like the 212th degree Fahrenheit that turns a pot of hot water into a plume of billowing steam.

There may still be disputes about exactly how much we're contributing to the warming of the earth's atmosphere and how much is naturally occurring, but what we can be scientifically certain of is that our continued use of fossil fuels is pushing us to a point of no return.

I'm no longer sceptical. Now I do not have any doubt at all. I think climate change is the major challenge facing the world. I have waited until the proof was conclusive that it was humanity changing the climate. The thing that really convinced me was the graphs connecting the increase of carbon dioxide in the environment and the rise in temperature, with the growth of human population and industrialisation.

There are no longer any serious scientists producing peer reviewed scientific journal articles that [deny anthropogenic global warming]. The real scientific debate is over. The people who say global warming isn't real, they must get together on Saturday nights and party with the ones who think the moon landing was staged on a movie lot in Arizona.

The world is already feeling the powerful effects of global warming, and far more dire consequences are predicted if we let the growing deluge of greenhouse gas emissions continue...
|

At the top of the world [the Arctic], you hear stories -- affirmed by decades of scientific investigation [on anthropogenic global warming] -- of changing weather patterns, melting ice, retreating glaciers, unprecedented wildfires, eroding coasts, and invasive species. You can see the evidence with your own eyes. There are no climate change skeptics inside the Arctic Circle.
|
| Agree |
|
The science isn't settled -- it's unsettling, and getting more so every year as the scientific community learns more about the catastrophic consequences of uncontrolled greenhouse gas emissions. The big difference I have with the doubters is they believe the IPCC reports seriously overstate the impact of human emissions on the climate, whereas the actual observed climate data clearly show the reports dramatically understate the impact.

| Mostly Agree |
|
Most of the global average warming over the past 50 years is very likely due to anthropogenic GHG increases and it is likely that there is a discernible human-induced warming averaged over each continent (except Antarctica).

Atmospheric carbon dioxide continues to increase due to the undisputed benefits that carbon-based energy brings to humanity. This increase will have some climate impact through CO2's radiation properties. However, fundamental knowledge is meagre here, and our own research indicates that alarming changes in the key observations are not occurring.
|
| Mostly Disagree |
|
The gap between the satellite observations and existing theory is large enough to cast serious doubt on all computer-model predictions of future warming. Whatever the cause of the gap, we cannot rely on GCM (General Circulation Models) forecasts of future warming. (GCMs are not even consistent with each other; their temperature forecasts vary by some 300 percent.) Until GCMs become validated by actual climate observations, they should not be used as the basis for policy.
|
| Mostly Disagree |
|
Global warming theory and GCMs (General Circulation Models) are found to be fundamentally flawed. A significant, if not dominant portion of temperature increases in recent decades has resulted from local surface heating processes due to land use change, urbanization, and even anthropogenic greenhouse gases.

So far the signal of a discernible human contribution to global climate change has not emerged from this natural variability or background noise.

[Sun and cosmic rays] will probably be able to account for somewhere between a half and the whole of the increase in the Earth's temperature that we have seen in the last century.

By the mid-21st century the planet will face another Little Ice Age, similar to the Maunder Minimum, because the amount of solar radiation hitting the Earth has been constantly decreasing since the 1990s and will reach its minimum approximately in 2041.

I predict that in the coming years, there will be a growing realization among the global warming research community that most of the climate change we have observed is natural, and that mankind’s role is relatively minor.
|
| Disagree |
|
Whatever the cause of the cooling trend, its effects could be extremely serious, if not catastrophic. Scientists figure that only a 1% decrease in the amount of sunlight hitting the earth's surface could tip the climatic balance, and cool the planet enough to send it sliding down the road to another ice age within only a few hundred years.

The link between the burning of fossil fuels and global warming is a myth. It is time the world's leaders, their scientific advisers and many environmental pressure groups woke up to the fact.

The global warming scam has been, arguably, the most extraordinary example of scientific fraud in the post-War period. So many people, and institutions, have been caught up in the web of deceit, master-minded by environmental activists working through NGOs and their manipulation of the IPCC processes, that the integrity of Western science is seriously at risk.
|

|
There are no experimental data to support the hypothesis that increases in human hydrocarbon use or in atmospheric carbon dioxide and other greenhouse gases are causing or can be expected to cause unfavorable changes in global temperatures, weather, or landscape... ...We also need not worry about environmental calamities even if the current natural warming trend continues. The Earth has been much warmer during the past 3,000 years without catastrophic effects.
|
| Disagree |
|
The atmospheric greenhouse effect is a well known natural phenomenon, mostly caused by atmospheric water vapour, that keeps our planet warm and habitable whereas (anthropogenic = human-made) global warming refers to a small extra greenhouse warming (0.5-1 C/33 C; 1-5 %) allegedly arising from an increase in atmospheric concentration of the minority greenhouse effect gas CO2 (carbon dioxide) – the later increase in turn possibly arising from fossil fuel burning.

Starting in 1997, we created a scorecard to see how climate model predictions were matching observations. The picture is not pretty with most of the predictions being wrong in magnitude and often in sign. [Hoyt gives each prediction a 'yes-no-undetermined' score. The current score in this case is 1-27-4]

I think the initial motivation by the IPCC (established in 1988) was good; it was an attempt to promote this particular scientific field. ... But so many [scientists] jumped in, and the media is looking for a disaster story, and the whole thing got out of control.
|
| Disagree |
|
Personal beliefs on climate change and rising sea levels should be delayed until just one of the many predictions made since 1985 on the basis of carbon additions to the atmosphere comes true.

With the complete discrediting of the ‘hockey stick’ curve of recent temperature change (McIntyre and McKitrick, 2003, 2005; Wegman, Scott and Said, 2006) that was the icon of their report, the IPCC case for dangerous human-caused warming now rests only on ambiguous anecdotal evidence, unvalidated computer models and misleading attribution studies (IPCC, 2007).
|

|
There is no atmospheric greenhouse effect, in particular CO2-greenhouse effect, in theoretical physics and engineering thermodynamics. Thus it is illegitimate to deduce predictions which provide a consulting solution for economics and intergovernmental policy.

Most leading geologists, throughout the world, know that the IPCC's view of Earth processes are implausible if not impossible.

The causes of these changes are cosmogenic...
