Verified by NOAA – Poor Weather Station Siting Leads to Artificial Long Term Warming

By Anthony Watts – Re-Blogged From WUWT

I’ve been saying for years that surface temperature measurements (and long term trends) have been affected by encroachment of urbanization on the placement of weather stations used to measure surface air temperature, and track long term climate. In doing so we found some hilariously bad examples of climate science in action, such as the official USHCN climate monitoring station at the University of Arizona, Tucson:

Urban Heat Island Influence Inadequately Considered in Climate Research

By Dr. Tim Ball – Re-Blogged From WUWT

The Intergovernmental Panel on Climate Change (IPCC) deliberately limited climate science to focus on CO2 and temperature. The United Nations Framework Convention on Climate Change (UNFCCC) directed them only to consider human causes of climate change. They used this to narrow the focus of all variables that create the climate and thus eliminate major variables that cause climate change. A major example is the so-called greenhouse gases (GHG). Three of them account for almost 100% of the total; by volume, they are Water vapor (H2O) (95%), Carbon dioxide (CO2) (4%) and Methane (CH4) (0.36%). There are no accurate measures of any of these regarding the amount actually in the atmosphere or the changes in input and output from natural sources over any period.

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.
