In the last 35 years of global warming, sun and climate have been going in opposite directions
97% of climate experts agree humans are causing global warming.
Models successfully reproduce temperatures since 1900 globally, by land, in the air and the ocean.
CO2 didn’t initiate warming from past ice ages but it did amplify the warming.
Most glaciers are retreating, posing a serious problem for millions who rely on glaciers for water.
Mars is not warming globally.
Climate scientists could make far more money in other careers – most notably, working for the oil industry.
Rising CO2 increases atmospheric water vapor, which makes global warming much worse.
The benefits of a price on carbon outweigh the costs several times over.
Through its impacts on the climate, CO2 presents a danger to public health and welfare, and thus qualifies as an air pollutant
Scientists have determined that the factors which caused the Little Ice Age cooling are not currently causing global warming.
Global temperature is still rising and 2010 was the hottest recorded.
Aerosols have been masking global warming, which would be worse otherwise.
No known natural forcing fits the fingerprints of observed warming except anthropogenic greenhouse gases.
Most glaciers are in rapid retreat worldwide, notwithstanding a few complicated cases.
We see a clear “short-term hot spot” – there’s various evidence for a “long-term hot spot”.
Glaciers are in rapid retreat worldwide, despite 1 error in 1 paragraph in a 1000 page IPCC report.
Those who contribute the least greenhouse gases will be most impacted by climate change.
‘Global warming’ and ‘climate change’ mean different things and have both been used for decades.
The ocean is absorbing massive amounts of CO2, and is becoming more acidic as a result.
And the sun has been recently cooling.
The actual data show high northern latitudes are warmer today than in 1940.
The iris hypothesis has not withstood the test of time – subsequent research has found that if it exists, the effect is much smaller than originally hypothesized, and may even slightly amplify rather than reducing global warming.
Soot stays in the atmosphere for days to weeks; carbon dioxide causes warming for centuries.
Jim Hansen had several possible scenarios; his mid-level scenario B was right.
There is no evidence that climate has chaotic “regimes” on a long-term basis.
The ‘OISM petition’ was signed by only a few climatologists.
Arctic sea ice has shrunk by an area equal to Western Australia, and summer or multi-year sea ice might be all gone within a decade.
The IPCC simply updated their temperature history graphs to show the best data available at the time.
Modern scientists, not anti-science skeptics, follow in Galileo’s footsteps.
A number of renewable sources already do provide baseload power, and we don’t need renewables to provide a large percentage of baseload power immediately.
The 97% consensus has been independently confirmed by a number of different approaches and lines of evidence.
Greenhouse warming is adding 100 times more heat to the climate than waste heat.
Winter snow cover in 2008/2009 was average while the long-term trend in spring, summer, and annual snow cover is rapid decline.
Preventing global warming is relatively cheap; business-as-usual will cause accelerating climate damage costs that economists struggle to even estimate.
The CERN CLOUD experiment only tested one-third of one out of four requirements necessary to blame global warming on cosmic rays, and two of the other requirements have already failed.
Blaming global warming on the movements of other planets is little more than ‘climastrology’ and curve fitting without a physical basis.
This detail is irrelevant to the observation of global warming caused by humans.
The sun was much cooler during the Ordovician.
Thousands of coral atolls have “drowned” when unable to grow fast enough to survive at sea level.
CFCs contribute at a small level.
Investment in renewable energy creates more jobs than investment in fossil fuel energy.
The Schmittner et al. study finds low probability of both very low and very high climate sensitivities, and its lower estimate (as compared to the IPCC) is based on a new temperature reconstruction of the Last Glacial Maximum that may or may not withstand the test of time.
Natural cycles superimposed on a linear warming trend can be mistaken for step changes, but the underlying warming is caused by the external radiative forcing.
CO2 and corresponding water vapor feedback are the biggest cause of global warming.
The data and research are unclear whether climate change is increasing extreme weather damage costs, but many types of extreme weather are becoming more intense and/or frequent, and disaster costs from extreme weather events are rising.
The IPCC 95% confidence that humans are responsible for most of the current global warming is simply a summary of the peer-reviewed scientific research.
Ljungqvist’s temperature reconstruction is very similar to other reconstructions by Moberg and Mann.
Removing CO2 would cause most water in the air to rain out and cancel most of the greenhouse effect.
Loehle and Scafetta’s paper is nothing more than a curve fitting exercise with no physical basis using an overly simplistic model.
The amount of heat energy coming out of the Earth is too small to even be worth considering.
Global warming is increasing the frequency, duration and intensity of heatwaves.
