High variability of Greenland surface temperature over the past 4000 years estimated from trapped air in an ice core. Geophysical Research Letters 38: 10.1029/2011GL049444.

Providing some background for their study Kobashi et al. (2011) write that, supposedly, “Greenland recently incurred record high temperatures and ice loss by melting, adding to concerns that anthropogenic warming is impacting the Greenland ice sheet and in turn accelerating global sea-level rise.” However, they state that “it remains imprecisely known for Greenland how much warming is caused by increasing atmospheric greenhouse gases versus natural variability.” (more…)

Jim’s Nature Trick

Dr. Jim’s 1988 projections weren’t looking so good, so he dropped an apple in the middle of his oranges. The red line is land only temperatures, but his projections were for global temperatures.

Let’s remove the inappropriate data and update it for 2011 so far.

Not looking too good, even with their frantic pink crayon. (more…)

Pick your proxy

What do we conclude when temperature proxies contradict both one another and real-world data?

We see here that a new proxy temperature measurement from South America shows the Medieval warm period and little ice age that Warmists like Michael Mann tried to “iron out” of their “hockey stick” graphs.

It also however shows a temperature upturn in the 20th century that exceeds the temperature observed in their proxy data for the Medieval warm period — which contradicts what we certainly know about the Medieval warm period — when the historical data that we have (Vikings farming in Greenland etc.) shows that period to be warmer than the present.

What do we see when we use THREE centuries of temperature data?

What do we see when we use THREE centuries of temperature data?

German geologist Dr. Friedrich-Karl Ewert has asked that question and answered it. He notes that the German weather bureau has temperature records going back as far as 1701 so decided to use them all to calculate temperature changes over time. He found nearly as many cooling trends as warming trends — giving an overall temperature change that is so small as to be best described as temperature stability.

Below is the introduction to an almost completely ignored press conference that he gave at the recent Bonn pow-wow. I also have the graphs accompanying the presentation and reproduce the first of them below. (more…)

Before Gore or the IPCC, the end was nigh

The Arctic Ocean is warming up, icebergs are growing scarcer and in some places the seals are finding the water too hot, according to a report to the Commerce Department yesterday from Consulafft, at Bergen, Norway. Reports from fishermen, seal hunters and explorers all point to a radical change in climate conditions and hitherto unheard-of temperatures in the Arctic zone.   (more…)

NCDC UrbanGate: how the urban warming was exported to U.S. countryside

Edward Long, a retired NASA physicist, wrote a fascinating 14-page paper for SPPI that needs to be read and verified:

Contiguous U.S. temperature trends using NCDC raw and adjusted data for one-per-state rural and urban station sets (PDF, frames)

He looked at the NCDC surface temperature records of the 48 main U.S. states (you don’t want me to spell “contiguous” right, do you?). If his work is valid, it is a shocker that actually reveals how the urban effects work and what a major team has done with them.

He took one rural and one urban station from each state among 48 of them. And let’s hope he didn’t cheat or cherry-pick. (more…)

U.S. Climate Data Compromised by Sensors’ Proximity to Heat Sources, Critics Say

Climategate: NOAA and NASA Complicit in Data Manipulation

Saturday, January 30th, 2010

Recent revelations from the Climategate emails, originating from the Climatic Research Unit at the University of East Anglia, showed how all the data centers — most notably NOAA and NASA — conspired in the manipulation of global temperature records to suggest that temperatures in the 20th century rose faster than they actually did.

This has inspired climate researchers worldwide to take a hard look at the data proffered, by comparing it to the original data and to other data sources. An in-depth report, co-authored by myself and Anthony Watts for the Science and Public Policy Institute (SPPI), compiles some of the initial alarming findings with case studies included from scientists around the world.

We don’t dispute the fact that there has been some cyclical warming in recent decades — most notably from 1979 to 1998 — but cooling took place from the 1940s to the late 1970s, again after 1998, and especially after 2001, all while CO2 rose. This fact alone questions the primary role in climate change attributed to CO2 by the IPCC, environmental groups, and others.

However, the global surface station data is seriously compromised. (more…)

NASA Climategate Exposed

*********

Climate researchers have discovered that NASA researchers improperly manipulated data in order to claim 2005 as “the warmest year on record.”

KUSI-TV meteorologist, Weather Channel founder, and iconic weatherman John Coleman will present these findings in a one-hour special airing on KUSI-TV on January 14 at 9 p.m. EST. A related report will be made available on the Internet at 6 p.m. EST on January 14 at www.kusi.com.

In a new report, computer expert E. Michael Smith and Certified Consulting Meteorologist Joseph D’Aleo discovered extensive manipulation of the temperature data by the U.S. government’s two primary climate centers: the National Climatic Data Center (NCDC) in Asheville, North Carolina and the NASA Goddard Institute for Space Studies (GISS) at Columbia University in New York City. Smith and D’Aleo accuse these centers of manipulating temperature data to give the appearance of warmer temperatures than actually occurred by trimming the number and location of weather observation stations. The report is available online at http://icecap.us/images/uploads/NOAAroleinclimategate.pdf. (more…)
