Climate & Environment Review
April 3, 2007

Climate & Environment Weekly is brought to you by The Center for Science and Public Policy (CSPP). CSPP is a non-profit, non-partisan public policy organization.

CSPP relies on scientific experts in many nations and the vast body of peer-reviewed literature to help lawmakers, policy makers, and the media distinguish between scientific findings that are agenda-driven and those that are based on accepted scientific methods and practices. In a timely manner, the Center's Science Watch Team alerts policy makers, the media, and the public to unreliable scientific claims and unjustified alarmism which often lead to public harm. We strive for a fair and balanced examination of science.

Stabalizing CO2 in Atmosphere at Current Levels to Stop Global Warming
It is generally accepted that to stabilize CO2 in the atmosphere at current levels it will be necessary to reduce worldwide CO2 emissions by 60%... >>Read More<<

Medieval Warm Period evidence - Igaliku Fjord, South Greenland
The authors conducted biostratigraphic diatom analyses on two ocean sediment cores retrieved from Igaliku Fjord (~60.95°N, 45.37°W), south Greenland, to obtain a record of changes in the hydrography and sea ice of the region during the late Holocene... >>Read More<<

Natural Climatic Variability: Northwest Europe
In the words of the authors, "this study focuses on one of the most interesting times of the early instrumental period in northwest Europe (from 1730-1745), attempting to place the extremely cold year of 1740 and the unusual warmth of the 1730s decade in a longer context." It relies primarily on "long (and independent) instrumental records together with extensive documentary evidence," as well as "unpublished subjective circulation charts developed by the late Hubert Lamb" and "others recently developed using more objective modern reconstruction techniques"... >>Read More<<

With five private jets, Travolta still lectures on global warming
His serious aviation habit means he is hardly the best person to lecture others on the environment. But John Travolta went ahead and did it anyway... >>Read More<<

Things more important that global warming - China's real estate market up 69 percent in 2006
This remarkable growth is fired by fossils fuels and enormous CO2 emissions, plus real pollutants. China opens a new coal-fired generation facility every three to five days, and will up to 2012... >>Read More<<

Forest Growth Trends in Northwestern Russia
Working in the Komi Republic in the northeast European sector of Russia (59°12'-68°25'N, 45°25'-66°10'E), the authors (1) collected discs and cores from 151 Siberian spruce trees and 110 Scots pines from which they developed ring-width chronologies that revealed yearly changes in forest productivity... >>Read More<<

CO2 emissions targets at risk from 'the roll to coal'
Soaring greenhouse gas emissions from power stations are seriously threatening Britain's new climate-change targets, launched in a blaze of publicity only two weeks ago, according to a new report... >>Read More<<

Climate Model Predictions of CO2-Induced ENSO Changes
Shortly after the powerful 1997-98 El Niño - which some have described as "the strongest in recorded history" (Jimenez and Cortes, 2003) - climate models began to suggest that future CO2-induced global warming would lead to stronger and more frequent El Niños (Timmermann et al., 1999; Collins 2000a,b; Cubasch et al., 2001)... >>Read More<<

USHCN Temperature Record of the Week - Pensacola, FL
To bolster our claim that "There Has Been Little Net Global Warming Over the Past 70 Years," each week we highlight the temperature record of one of the 1221 U.S. Historical Climatology Network (USHCN) stations from 1930-2000... >>Read More<<

Positive aspect of global warming – Central Africa
The authors conducted high-resolution analyses of Mg concentrations in authigenic calcite found in five sediment cores retrieved from Lake Edward in central equatorial Africa to develop a water balance history of the region that spans the past 1400 years... >>Read More<<

Effects of Atmospheric CO2 Enrichment on Spring Wheat Yields in a Semi-Arid Region of China
The authors studied the effects of minor-to-modest CO2 concentration increases of 14.5, 40 and 54.5 ppm on leaf area index, leaf area duration, shoot biomass and yield of spring wheat (Triticum aestivum cv. Dingxi 24) grown for two years in a semi-arid region of China under (1) natural conditions, (2) with irrigation and (3) with irrigation and added fertilizer... >>Read More<<

Precipitation (Variability - Africa) – Summary
Climate alarmists vociferously contend that global warming is responsible for creating more frequent and greater extremes of various types of weather. We here investigate this claim as it pertains to precipitation in Africa, focusing on the occurrence of extreme droughts and floods... >>Read More<<

Earlier Quaternary vs. Present-Day Coral Growth Rates
The authors used digital photography, image analysis and measurements in the field to determine the original growth rates of long-dead Quaternary corals found in exposed onshore limestone deposits near the margins of Hoga and Kaledupa Islands in the Wakatobi Marine National Park of Indonesia, after which they compared them to the growth rates of present-day corals of the same genera (Porites and Favites) living in the same area... >>Read More<<
