UN IPCC Scientist: 'No convincing scientific arguments to support claim that increases in greenhouse gases are harmful to the climate'

Selected excerpts from UN IPCC scientist's recent testimony.

IPCC reviewer and climate researcher and chemist Dr. Vincent Gray of New Zealand is an expert reviewer on every single draft of the IPCC reports going back to 1990 and author of The Greenhouse Delusion: A Critique of "Climate Change 2001. Dr. Gray's research is featured on page 155 of the 2009 edition of the 255-page "U.S. Senate Minority Report Update: More Than 700 International Scientists Dissent Over Man-Made Global Warming Claims"

Below are selected excerpts of his testimony before New Zealand's Committee for the Emissions Trading Scheme Review May 5, 2009:

I am an experienced research chemist, with a PhD from Cambridge 1946, and a long research career in the UK, France, Canada, New Zealand and China. I have over 100 scientific publications, many of them on climate science, which I have studied intensively for the past 18 years.

I have been an Expert Reviewer for the IPCC Reports since the beginning in 1990.I submitted 1,898 comments to the last (fourth) Working Group I (Science) Report.

I was recently invited to the Beijing Climate Center as a Visiting Scholar and I recently lectured to a Conference in New York.

I have reluctantly concluded, after detailed study of the evidence presented by the IPCC, that there are no convincing scientific arguments to support the claim that increases in greenhouse gases are harmful to the climate. [...]

Climate Model Predictions: It's Time for a Reality Check

The fear of anthropogenic global warming is based almost entirely upon computerized climate model simulations of how the global atmosphere will respond to slowly increasing carbon dioxide concentrations. There are now over 20 models being tracked by the IPCC, and they project levels of warming ranging from pretty significant to catastrophic by late in this century. The following graph shows an example of those models' forecasts based upon assumed increases in atmospheric carbon dioxide this century.

While there is considerable spread among the models, it can be seen that all of them now produce levels of global warming that can not be ignored.

But what is the basis for such large amounts of warming? Is it because we know CO2 is a greenhouse gas, and so increasing levels of atmospheric CO2 will cause warming? NO!...virtually everyone now agrees that the direct warming effect from extra CO2 is relatively small - too small to be of much practical concern.

Over 200 New Amphibians Found in Madagascar

Highlighting a "vast underestimation" of Madagascar's natural riches, up to 221 new species of amphibians have been found on the island country, including the frog Boophis ulftunni, pictured. The find nearly doubles the number of known amphibians in Madagascar, a new study says.

Two Brown Bear Populations In Spain In Danger of Extinction Have Been Isolated For Past 50 Years

The situation of bears in the Iberian Peninsula is critical. Researchers from the University of Oviedo (UO) and the Superior Council of Scientific Research (SCSR) have performed a genetic identification based on the analysis of stools and hair of brown bears (Ursus arctos) from the Cantabrian mountain range, gathered between 2004 and 2006.

The non-invasive analysis of 146 samples has allowed for the identification of 39 bears in the western sub-population, and 9 in the eastern one, so as to show the genetic structure of the population. In order to obtain the individual genotypes of the bears, scientists have employed 18 micro-satellite markers in a joint fashion, and a sex marker with high-class genetic technology.

'Sobering' Decline Of Caribbean's Big Fish, Fisheries: Overfishing Deemed Most Likely Cause

Sharks, barracuda and other large predatory fishes disappear on Caribbean coral reefs as human populations rise, endangering the region's marine food web and ultimately its reefs and fisheries, according to a sweeping study by researcher Chris Stallings of The Florida State University Coastal and Marine Laboratory.

While other scientists working in the Caribbean have observed the declines of large predators for decades, the comprehensive work by Stallings documents the ominous patterns in far more detail at a much greater geographic scale than any other research to date.

"Seeing evidence of this ecological and economic travesty played out across the entire Caribbean is truly sobering," said Associate Professor John Bruno of the University of North Carolina at Chapel Hill, who served as the PLoS One academic editor for Stallings' new paper.

Rare derecho sweeps across Southern US - widespread damage

On Sunday, a significant windstorm called a derecho, swept across 5 states, knocking down trees and power lines across the South.

Southeast Texas, Central Louisiana, South Mississippi, South and parts of Central Alabama, and North Central Georgia all were affected.

A derecho is a widespread and long-lived, violent convectively induced straight-line windstorm that is associated with a fast-moving band of severe thunderstorms in the form of a squall line, usually taking the form of a bow echo.

Heavy rains kill 19 in Brazil, leave 186K homeless

Sao Paulo - Floods and mudslides from months of heavy rains in northern Brazil have driven more than 186,000 from their homes, killed at least 19 people and cut off shipments from a huge Amazon iron mine, officials said Tuesday.

Television footage showed the rooftops of houses poking out of inundated towns and people using boats to move around in their cities. Mudslides swamped homes and forced residents to move in with relatives and pack into emergency shelters.

1,200 homes ordered evacuated amid California wildfire

Santa Barbara - Authorities in Southern California have ordered about 1,200 homes to evacuate because of a wind-driven wildfire burning in Santa Barbara County.

Fire Capt. David Sadecki says the blaze, which erupted Tuesday afternoon, is burning less than a square mile along the foothills above Santa Barbara. He says winds are pushing the fire toward homes.

Sun Oddly Quiet - Hints at Next "Little Ice Age"?

A prolonged lull in solar activity has astrophysicists glued to their telescopes waiting to see what the sun will do next - and how Earth's climate might respond.

The sun is the least active it's been in decades and the dimmest in a hundred years. The lull is causing some scientists to recall the Little Ice Age, an unusual cold spell in Europe and North America, which lasted from about 1300 to 1850.

The coldest period of the Little Ice Age, between 1645 and 1715, has been linked to a deep dip in solar storms known as the Maunder Minimum.

During that time, access to Greenland was largely cut off by ice, and canals in Holland routinely froze solid. Glaciers in the Alps engulfed whole villages, and sea ice increased so much that no open water flowed around Iceland in the year 1695.

But researchers are on guard against their concerns about a new cold snap being misinterpreted.

"[Global warming] skeptics tend to leap forward," said Mike Lockwood, a solar terrestrial physicist at the University of Southampton in the U.K. (Get the facts about global warming.) He and other researchers are therefore engaged in what they call "preemptive denial" of a solar minimum leading to global cooling.

Hot-air doomsayers

In Heaven and Earth - Global Warming: The Missing Science, I predicted that the critics would play the man and not discuss the science. Initial criticism appeared before the book was released three weeks ago.

Well-known catastrophists criticised the book before they actually received a review copy. Critics, who have everything to gain by frightening us witless with politicised science, have now shown their true colours. No critic has argued science with me. I have just enjoyed a fortnight of being thrashed with a feather.

Despite having four review copies, ABC's Lateline photocopied parts of chapters and sent them to an expert on gravity, a biologist and one who produces computer models. These critics did not read the book in its entirety. The compere of Lateline claimed that he had read the book yet his questions showed the opposite. When uncritical journalists have no science training, then it is little wonder doomsday scenarios can seduce them.

In The Age (Insight, May 2), David Karoly claims that my book "does not support the answers with sources". Considering that the book has 2311 footnotes as sources, Karoly clearly had not read the book. Maybe Karoly just read up to page 21, which showed that his published selective use of data showed warming but, when the complete set of data was used, no such warming was seen.
