During the first 6 months of 2017, 285 scientific papers have already been published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and mainstream media.
These 285 new papers support the position that there are significant limitations and uncertainties inherent in our understanding of climate and climate changes. Climate science is not settled.

Les hommes politiques, à l’image de Barack Obama avancent que 97% des scientifiques sont d’accord sur les causes humaines et les dangers du réchauffement climatique. Des chercheurs ont étudié l’ensemble des 11 944 publications sur le climat parues entre 1991 et 2011. Les résultats publiés en 2013 montrent que près de 66% des publications n’expriment pas d’avis, ni positif, ni négatif sur le réchauffement climatique.

In a new study, scientists puzzled by the sudden ice loss matched satellite images of Antarctica with weather data from the second half of 2016 to figure out what caused so much of the ice to melt. They found that a series of remarkable storms during September, October and November brought warm air and strong winds from the north that melted 75,000 square kilometers (30,000 square miles) of ice per day. That’s like losing a South Carolina-sized chunk of ice every 24 hours.

… dont août 1911 l’un des mois les plus chauds de l’histoire et 1947 (40°C à Paris les 27 et 28 juillet, record absolu depuis 1873). Emmanuel Leroy Ladurie indique qu’au dix-huitième siècle siècle les canicules pouvaient se répéter plusieurs étés consécutifs : ainsi les années 1705, 1706 et 1707, et le « couple brûlant » (sic) des années 1718 et 1719 « avec sauterelles africaines jusqu’au Languedoc ».

The only two people who were qualified to review this data tampering by RSS, Dr. Roy Spencer and Dr. John Christy, were not consulted and the changes were not submitted for peer review to them. This is very severe malfeasance, and standard practice for climate scientists. Their job is to push global warming, not do science.

Estimates of climate change damage are central to the design of climate policies. Here, we develop a flexible architecture for computing damages that integrates climate science, econometric analyses, and process models. We use this approach to construct spatially explicit, probabilistic, and empirically derived estimates of economic damage in the United States from climate change.

Proponents of drastic greenhouse gas controls claim that human greenhouse gas emissions cause global warming, which then exacerbates the frequency and intensity of extreme weather events, including extreme heat, droughts, floods, and storms such as hurricanes and cyclones.
In fact, even though reporting of such events is more complete than in the past, morbidity and mortality attributed to them has declined globally by 93%–98% since the 1920s

For years, RSS have been an embarrassment to the climate establishment. Their satellite data has consistently shown the pause in global temperatures since 1998, which so many scientists have attempted to explain.
At the same time, the surface datasets of GISS, NOAA and HADCRUT have diverged, with the help of adjustments, to show much greater warming.
The pressure on RSS to conform has been immense, and now the inevitable has happened. Highly conveniently they have found huge errors in their previous version, and have now adjusted to a new version, v4, which miraculously finds that global warming has continued unabated after all!

Carbon dioxide truly is “the gas of life.” The plants that feed us and wildlife can’t live without inhaling CO2, and then they exhale the oxygen that lets humans and animals keep breathing.
Our crop plants evolved about 400 million years ago, when CO2 in the atmosphere was about 5000 parts per million! Our evergreen trees and shrubs evolved about 360 million years ago, with CO2 levels at about 4,000 ppm. When our deciduous trees evolved about 160 million years ago, the CO2 level was about 2,200 ppm – still five times the current level.

Statistician Bjorn Lomborg had already pointed out that the Paris CO2 emission promises would cost $100 trillion dollars that no one has, and make only a 0.05-degree difference in Earth’s 2100 AD temperature. Others say perhaps a 0.2 degree C (0.3 degrees F) difference, and even that would hold only in the highly unlikely event that all parties actually kept their voluntary pledges.

For the last 3 years, human CO2 emissions rates have not risen. In fact, according to the IEA, we burned slightly more fossil fuels in 2014 than we did in both 2015 and 2016.
Despite the lack of growth – even slight decline – in human emissions rates during 2014 – 2016, the atmospheric CO2 parts per million (ppm) concentration grew rapidly – by more than 8 ppm (397 ppm to 405 ppm).

If aliens sent an exploratory mission to Earth, one of the first things they’d notice — after the fluffy white clouds and blue oceans of our water world — would be the way vegetation grades from exuberance at the equator through moderation at mid-latitudes toward monotony at higher ones. We all learn about this biodiversity gradient in school, but why does it exist?

Between the start of 1997 and the end of 2014, average global surface temperature stalled. This 18-year period is known as the global warming pause, also sometimes referred to as the global warming hiatus. The rise in global temperatures that alarmed climate campaigners in the 1990s had slowed so much that the trend was no longer statistically significant. It has been the subject of much research and debate in peer-reviewed scientific journals.

Sea level alarmists often claim that the rate of sea level rise is increasing. They need to do this to convince the public that the innocuous 7” or so of sea level rise experienced in the 20thC is suddenly going to turn into meters by 2100.
