As Hurricane Maria heads north as a Cat 3 storm, much is being made of the fact that it is the strongest hurricane to hit Puerto Rico since 1928. The implication is that Maria must have been exceptionally strong.

Frizzlers are always telling you what you need to do is cut back, have less children, drive smaller cars, use less energy and pay more tax and just die off, evil human, you know, because your presence is just such a pain for liberal elites to deal with. It’s all a con, a scam and nothing else.

Facts must be available in the form of irrefutable data and observations. The Earth is no laboratory where experiments can be repeated at will under well controlled conditions; on the contrary, any observations is made only once and in association with a multitude of disturbances that may or not be correlated with the target parameters. Therefore, the ability to develop and verify scientific climate theories is limited.

Do you want to know the origins of the 2-degree temperature target that underpins much of climate policy discussions and action?

Large earthquakes are more likely to occur when there is a full or new moon because of the gravitational pull on tides, a new study suggests.

Arctic sea ice extent is up 40% from this date five years ago.

Greenland’s surface gained ten times as much ice as it did five years ago, and was the fifth highest on record.

Greenland’s most famous glacier, the Petermann Glacier, has grown substantially and steadily over the past five years.

Climate alarmists have finally admitted that they’ve got it wrong on global warming. This is the inescapable conclusion of a landmark paper, published in Nature Geoscience, which finally admits that the computer models have overstated the impact of carbon dioxide on climate and that the planet is warming more slowly than predicted.

Weather and climate analyst Schneefan here writes that the 2017/18 winter in Europe could be one of the coldest of the last 20 years.

Violent collisions between the growing Earth and other objects in the solar system generated significant amounts of iron vapor, according to a new study by LLNL scientist Richard Kraus and colleagues.

Abstract: The wasted and misspent money at NASA GISS and all climate research institutions is staggering. We continue to follow the money.

Among the greatest challenges humankind has faced throughout its history, feeding the world’s hungry ranks at or near the very top of the list. And with the world’s population expected to top nine billion between 2050 and 2100, this issue will surely become even more important in the coming decades.

Barn owls keep their acute sense of hearing into old age, scientists have discovered. Previously, starlings have been found to have this ability, suggesting birds are protected from age-related hearing loss.

September 18 used to be a hot day in the US, but temperatures have plummeted over the past century.

On this date in 1925, temperatures were over 100 degrees in much of the Midwest and South.

In his recent article on WUWT titled “HADCRU Power and Temperature” Andy May refers to the challenges of modelling the atmosphere. He wrote,

The greenhouse effect (GHE), when calculated this way, shows an imbalance of 390-239=151 W/m². Kiehl and Trenberth, 1997 calculated a similar overall forcing of 155 W/m² using the same procedure. This GHE calculation makes a lot of assumptions, not the least of which is assuming the Earth has an emissivity of 1 and is a blackbody. But, here we want to consider the problem of using a global average temperature (T) for the Earth, which is a rotating sphere, with only one-half of the sphere facing the Sun at any one time.

Scientists have seen once again just how dynamic a place the underside of the Antarctic ice sheet can be. Survey data collected from the middle of the White Continent shows liquid water is being frozen on to the bottom of the sheet in huge quantities.
