Another UHI effect – thunderstorms & lightning

The March-April edition of WeatherWise magazine has an interesting article in it regarding UHI (Urban Heat Island) effects of enhancing thunderstorm formation in the downwind heat plume. It Stems from…

Stanford: Urban CO2 domes mean more death

I find it funny though, that this study (full PDF here) mentions urban warming related to CO2 only. The terms “Urban Heat Island” (and variants including UHI) are not found…

A UHI Tale of Two Cities

By Steven Goddard and Anthony Watts Fort Collins, Colorado is most famous for Balloon Boy, and Boulder, Colorado is most famous for Jon Benet and Ward Churchill. Both are hotbeds…

Spencer: Global Urban Heat Island Effect Study – An Update

by Roy W. Spencer, Ph. D. This is an update to my previous posts [here and here on WUWT] describing a new technique for estimating the average amount of urban…

Spencer's UHI -vs- population project – an update

In case you missed it, Roy Spencer performed a unique and valuable analysis comparing International Hourly Surface data to population density to provide a simple gauge for the Urban Heat…

Spencer: Using hourly surface data to gauge UHI by population density

I believe this is a truly important piece of work. I hope Dr. Spencer will submit it to a journal. I’m grateful to Dr. Spencer for his email suggesting I…

A new paper comparing NCDC rural and urban US surface temperature data

Note: See update below, new graph added. There’s a new paper out by Dr. Edward Long that does some interesting comparisons to NCDC’s raw data (prior to adjustments) that compares…

UCAR: Roof white out helps UHI

I find it humorous thatUCAR had to resort to modeling to prove something that can be measured empirically. But then again this is UCAR, and they have a big computer…

Climategate intensifies: Jones and Wang apparently hid Chinese station data issues

UPDATE: UEA/CRU has responded! http://www.uea.ac.uk/mac/comm/media/press/CRUstatements/guardianstatement Looks like a homogenized data comparison. h/t to WUWT reader “splice” ============================== It looks like Doug Keenan has been right all along. He must feel…

UHI is alive and well

One of the most ridiculous claims recently related to Menne et al 2010 and my surfacestations project was a claim made by DeSmogBlog (and Huffington Post who carried the story…

Picking out the UHI in climatic temperature records – so easy a 6th grader can do it!

The Urban Heat Island effect on temperature records is real, despite what some people wish you to believe. Peter, a sixth grader, and his dad, thought so too, and take…

Climategate grows to include other research institutions

UPDATED: By Douglas J. Keenan – special for WUWT Phil Jones tried to hush my paper. SUNY Albany won’t discuss the investigation my paper initiated. And QUB ignored my three…

Correcting the surface temperature record for UHI

As we’ve seen in this report from John Goetz, GISS: worlds airports continue to run warmer than ROW a significant portion of the GHCN (Global Historical Climate Network) surface temperature…

GISS: World's airports continue to run warmer than ROW

Guest post by John Goetz As noted in the previous post, GISS has released their monthly global temperature summary for June, 2009. This month’s whopping anomaly of 0.63C is once…

NCDC's USHCN2 paper: some progress, some duck and cover

The fact that my work is mentioned by NCDC at all is a small miracle, even if it is “muted”, as Roger says. However, I’m pleased to get a mention…

How not to measure temperature, part 86: when in Rome, don't do as the Romans do.

This is a preliminary post to a much more detailed one coming from my friend Paolo Mezzasalma. who is doing a tour of Italy’s weather stations. While there are significant…

Finally – an honest quantification of urban warming by a major climate scientist

This is a small bombshell. I’ve been telling readers about UHI since this blog started. One notable example that I demonstrated by actual measurement is Reno, NV: Click for larger…

New Google Earth tools let us explore the land use changes around climate stations over time

This past week Google introduced the latest iteration of their popular earth visualization program – Google Earth Version 5.0 In it was something I had been hoping for for months:…

Waste heat could warm the earth? Perhaps it has already started.

Excerpt of an article from the New Scientist, 01 December 2008 by Mark Buchanan (h/t to Richard Hegarty) EVEN if we turn to clean energy to reduce carbon emissions, the…
