More surfacestations project vindication: Strong UHI temperature biases confirmed in USA

WUWT readers may recall that NOAA did an experiment at Oak Ridge National Laboratory that vindicated my findings about the effects of local urbanization on surface temperature measurements. The urban heat island (UHI) effect is strongly affected by urban-scale changes to local land surfaces. Basically, the more asphalt, concrete, buildings, etc. that exist near a…

How fast is the world warming? Is it burning?

Reposted from The Fabius Maximus Blog Larry Kummer, Editor Climate change, Science & Nature 17 August 2019 Summary: Let’s take a break from political bickering to see how fast the Earth is warming. Just the facts, please. The world has been warming since the middle of the 19th century. Human-caused warming has become the dominant…

‘Hidden’ NOAA temperature data reveals that 6 of the last 9 months were below normal in the USA – and NOAA can’t even get June right

A review of state-of-the-art climate data tells a different story than what NOAA tells the public. While media outlets scream “hottest ever” for the world in June and July (it’s summer) and opportunistic climate crusaders use those headlines to push the idea of a “climate crisis” the reality is for USA is that so far…

Some perspective on the “massive heatwave” in the USA

Mark Albright, from the Dept. of Atmospheric Sciences at the University of Washington writes: Many of us saw the exaggerated headlines about the “massive heat wave” gripping the USA over the past weekend of 20-21 July 2019:https://www.cbsnews.com/live-news/heat-wave-2019-extreme-heat-advisory-warning-deaths-latest-weather-forecast-us-nyc-2019-07-20/ Well , there is an explanation, it’s called mid-summer. Climatologically speaking, the two warmest days of the year…
