This article examines the continued cooling of CET this century

  • Looks at a similar scenario of regional cooling in America
  • Examines CET related urbanisation issues, and the current Met office allowances for this
  • Notes the centuries long general warming of our climate.
  • Notes considerable English seasonal variability over the centuries
  • Examines the key component parts of the weather that affect the British Isles
  • Queries whether wind direction, strength and longevity are major factors in shaping our climate over the centuries.

New USGS Study Shows Heat Retaining Concrete and Asphalt Have Encroached Upon US Climate Stations

By Anthony Watts – Re-Blogged From http://www.WattsUpWithThat.com

A new study from USGS by Keven Gallo and George Xian verifies what we’ve already learned and published on via the Surface Stations project; that concrete and asphalt (aka impervious surfaces) have increased near weather stations that are used to monitor climate. In this case, it is the much studied USHCN, that climate network I presented a poster on at AGU 2015. Details here.

What is most important about this paper is that it quantifies the percentage of stations that have had increased amounts of impervious surface area getting closer to the stations. As I have long since maintained, such things act as heat sinks, which increase the night-time temperature when they released the stored energy from the sun that was absorbed during the day as infrared, warming the air near the thermometer, and thus biasing the minimum temperature upwards.

Flooding And Planning: We Don’t Need To Live Near Rivers Anymore

By Dr Tim Ball – Re-Blogged From http://www.WattsUpWithThat.com

Petula Clark sang, “Don’t sleep in the subway, darling. Don’t stand in the pouring rain.” More helpful advice would urge, “Don’t live in the floodplain, darling. Don’t you know it’s pouring rain?” It’s called a floodplain for a reason. The dangers of flooding mostly involve people living in dangerous places. Why are people allowed to live in these regions without being forced to accept full responsibility for their actions? They are encouraged by governments and insurance that enable bad practices, questionable, and unnecessary behavior.

There was a time when living near a river was important for transport, water supply, waste removal, and even food supply. We don’t need to live close to rivers or at least within the area identified as the floodplain. If you live there, flooding is inevitable, even if flooding protection is in place. In fact, the protection creates a false sense of security. Inevitably the protection will fail through neglect, accident, or water levels that exceed the design capacity.

Weekly Climate and Energy News Roundup #177

The Week That Was: April 18, 2015 – Brought to You by www.SEPP.org The Science and Environmental Policy Project

THIS WEEK: By Ken Haapala, President, SEPP – Re-Blogged From http://www.WattsUpWithThat.com

Energy Not Heat, Exclusively: A source of frustration for members of SEPP, and others, are the efforts by some of classifying these skeptics as denying the existence of the greenhouse effect, often by claiming that the greenhouse effect is contrary to the second law of thermodynamics. The law applies to the flow of heat (thermal energy) from a warmer body to a cooler one. The atomic theory of heat (thermal energy) is based on the motion of atoms and/or molecules. Though it may use atoms, the transfer of energy does not require them. There forms of energy other than heat.

Theory and the Global Warming Pause

cropped-bob-shapiro.jpg   By Bob Shapiro

Global temperature is an average of the daily high and the daily low (Tmax & Tmin). If only it were that simple.

There are very few official weather stations on land, and a laughably low coverage for the 3/4 of the earth’s surface covered by water. To make up for this lack of data, climatologists divvy up the earth’s surface into grid boxes (5 degrees X 5 degrees), and “infill” any (A LOT) of the missing data, using readings from stations up to 1200 Km away – that’s like filling in Kansas from a thermometer in Galveston, TX.

Climatologists also do “quality control” on the instrumental data to adjust for station moves or other perceived problems. You would think that all the adjustments pretty much would cancel each other out, but if you think that is what actually happens, then I have a bridge I’d like to sell you. The reality is that older data is adjusted downward while newer data gets adjusted upward – and the same data gets adjusted several times, always in the direction which would make the trend look to be more steeply warming.

Adjustments & UHI Account for Most of the Rise in Temperatures

cropped-bob-shapiro.jpg  By Bob Shapiro

The temperature record using the 1221 “official” weather stations in the US Historical Climatology Network, are not useful in determining whether there is any danger of Catastrophic Anthropogenic Global Warming (CAGW), that is man-made global warming. We already have seen that over 90% of these stations cannot measure more closely than the nearest degree Celsius. (In 70% of these stations, the expected error is greater than 2 degrees C.)
