CO2 is a greenhouse gas and it has been rising steadily. How can you deny global warming?
The Earth has warmed – and cooled – over the past 50 years. We’ve also experienced periods of “unusual” weather and “normal” weather, more frequent and intense storms and droughts, less frequent and less severe storms and droughts. However, I don’t agree that humans are responsible, or that climate change is becoming dangerous or catastrophic.
CO2 is a trace gas, but without it life on earth would be impossible. Carbon dioxide
fertilizes algae, trees and crops, to provide food for humans and animals. We inhale
oxygen and exhale CO2. Slightly higher atmospheric CO2 levels cannot possibly supplant
the numerous complex and inter-
As University of London professor emeritus Philip Stott has noted: “The fundamental
point has always been this. Climate change is governed by hundreds of factors, or
variables, and the very idea that we can manage climate change predictably by understanding
and manipulating at the margins one politically-
Even the global warming activists at RealClimate.org acknowledged this in a September 20, 2008 article, where they said “The actual temperature rise is an emergent property resulting from interactions among hundreds of factors.” CO2 is not the tail that wags the dog.
Haven’t the past few years shown global warming to be worse than we thought?
As the real world evidence mounts that global warming claims are failing, climate
activists have ramped up predictions of future climate change impacts, declaring
that it is “worse than we thought.” But a prediction or projection 50-
The scientific reality is that on virtually every claim – from A to Z – the claims of manmade climate disaster promoters are failing. In many instances the claims are moving in the opposite direction.
Antarctic sea ice has been at or near record extent during the past few summers and is now expanding. Arctic sea ice has been ebbing and flowing due to giant storms, ocean currents and high pressure days. Polar bears are thriving across the Arctic. Sea level rise has not been accelerating.
Cholera and malaria are not related to climate change and refuse to follow global warming predictions. Mount Kilimanjaro melt fears are being mocked by gains in snow cover. Global temperatures have been stable for more than a decade, and many scientists are predicting global cooling is ahead. Deaths due to extreme weather are declining dramatically.
Global tropical cyclone activity is near historic lows, the frequency of major U.S. hurricanes has declined, and big tornados have dramatically declined since the 1970s. In fact, 2012 is thus far the quietest tornado and quietest hurricane summer on record. In fact, by November 2012 could mark the quietest long term hurricane period since the Civil War, with no major hurricane strikes on the U.S. in seven years.
If CO2 is not the main driver of global temperatures, what is? The Sun?
When global temperatures are the question, the answer is not the sun or CO2. It is the sun, volcanoes, tilt of the Earth’s axis, water vapor, methane, clouds, ocean cycles, plate tectonics, shifting ocean currents, albedo (Earth’s changing reflective properties), atmospheric dust, atmospheric circulation, cosmic rays, particulates like carbon soot and volcanic dust, forests and grasslands, urban and other land use changes. Climate change is governed by hundreds of factors, not just CO2.
How can you ignore thousands of scientists who say manmade global warming is a serious threat?
The idea that there is a “scientific consensus” does not hold up. Scientists who
are skeptical about “dangerous manmade climate change” have been speaking out for
years. Just this year, two prominent former believers in man-
“Gaia” scientist James Lovelock had been “alarmist” about climate change for years. Now he says “The problem is we don’t know what the climate is doing. We thought we knew 20 years ago.”
German meteorologist Klaus-
In 2010, a report documented that More Than 1000 International Scientists Dissented
Dr. William Schlesinger agrees with the UN climate view but has admitted that only 20% of UN IPCC scientists deal with climate. In other words, 80% of the UN’s IPCC membership are experts in other fields and have no dealing with or expertise in climate change as part of their academic studies.
How can you reject the NAS, which agrees that manmade global warming is a threat?
Proponents of manmade global warming often point out that the National Academy of
Sciences (NAS) and American Meteorological Society (AMS) have issued statements endorsing
The governing boards are steeped in politics and seek more funding for “research” that promotes currently accepted viewpoints. The full membership of actual scientists never gets to vote on the activist statements and in many cases is completely unaware until too late that the boards have issued them. Many such organizations have faced open rebellion by their skeptical member scientists for such actions: the American Chemical Society, American Physical Society and International Geological Congress.
97% of scientists say manmade climate change is real. How can you go against them?
The claim that “97% of scientists agree” is based on 77 anonymous scientists who responded to a survey. The survey started by seeking opinions from 10,257 scientists. However, only 77 responded. So the 97% “consensus” claim is not based on thousands of scientists or even hundreds of scientists – but only on 77. Out of those 77 scientists, 75 answered the survey to form the mythical 97% “consensus.”
Global average temperatures are accelerating. We must act now to cool the planet.
Actually, global temperatures have been holding steady for more than a decade. 1998
is still the high point in global temperatures during the recent era. While 2005
and 2010 were both declared “hottest” years by global warming proponents, a closer
examination revealed that the claims were “based on year-
In September 2012, even UN IPCC scientist Phil Jones presented data that revealed there has been no global temperature change for the last 16 years!
2012 was the “hottest summer” on record. Isn’t manmade global warming clearly to blame?
It was a hot summer in much of the continental U.S. But it was also a very cold summer in Alaska and parts of Europe, and a very cold winter in places like South Africa, where the seasons are reversed. Continental USA represents only 1.6% of the Earth’s surface.
Media and climate activists attempted to extrapolate this small surface area heat
wave into a global trend – but it wasn’t. In fact, global temperatures were below
Weren’t this summer’s heat waves unprecedented? We can't let that happen again.
Climatologist Dr. John Christy rejected such claims in testimony to Congress in September
2012: “The recent claims about thousands of new record high temperatures were based
on stations whose length-
“About 75% of the states recorded their hottest temperature prior to 1955, and over 50 percent of the states experienced their record cold temperatures after 1940,” Christy pointed out.
Arctic ice melted to record lows in 2012. Isn’t that due to manmade global warming?
Recent Arctic ice changes are not “proof” of manmade global warming, nor are they
unprecedented, unusual or cause for alarm, according to experts and multiple peer-
Reuters news finally reported that the Arctic storm played a “key role” in ice reduction,
and multiple peer-
Global warming activists have long hyped satellite era data, which begin in1979,
to claim record low Arctic sea ice – while ignoring the satellite data that show
record sea ice expansion in the Antarctic. Moreover, satellite monitoring of Arctic
ice began at the end of a 40-
We have had similar Arctic ice panics in the past. A November 2, 1922 Washington Post article was headlined “Arctic Ocean getting warm: Seals vanish and icebergs melt.” The Arctic Ocean is warming, icebergs are growing scarcer and in places the seals are finding the water too hot, it said.
“There is a lack of evidence to blame humans for an increase in extreme events. One
cannot convict CO2 of causing any of these events, because they’ve happened in the
past before CO2 levels rose,” climatologist John Christy testified before Congress
in 2012. “There are innumerable types of events that can be defined as extreme events
– so for the enterprising individual (unencumbered by the scientific method), weather
statistics can supply an unlimited, target-
Scientists rebuked former Vice President Al Gore for attempting to link CO2 levels and extreme weather. “Al Gore is doing a disservice to science by overplaying the link between climate change and weather,” said Myles Allen. “When Al Gore said last week that scientists now have ‘clear proof that climate change is directly responsible for the extreme and devastating floods, storms and droughts,’…my heart sank.”
“There is no evidence that disasters are getting worse because of climate change,” notes Professor Roger Pielke, Jr. “There’s really no evidence that we’re in the midst of an extreme weather era – whether man has influenced climate or not.”
Aren’t the recent droughts in the U.S. due to man-
Across time scales required for any meaningful analysis, “droughts have, for the most part, become shorter, less frequent, and cover a smaller portion of the U. S. over the last century,” Professor Roger Pielke, Jr. observes. “U.S. Midwestern drought has decreased in past 50+ years? That is not skepticism; that’s according to the UN Intergovernmental Panel on Climate Change,” he adds.
Even U.S. government scientists have admitted that recent droughts are not due to climate change. “This is not a climate change drought,” said Dr. Robert Hoerling, a NOAA research meteorologist, who served as the lead author of the U.S. Climate Change Science Plan Synthesis and Assessment Report: “The good news,” he emphasized, “is that this isn’t global warming. This is not the new normal in terms of drought.”
For scientists who take the long view of history, the U.S. drought of 2012 is “merely a climatological blip, E&E News reported, in an article titled “Dust Bowl and 1988 both eclipse 2012 drought, scientists say.”
Isn’t manmade global warming causing increases in rainfall?
No. Any attempt to link man-
In Australia, climate activists were caught blaming too little rain on manmade global warming and then – when there was too much rain – they blamed that on manmade global warming. Other studies have found both temperatures and precipitation were higher 1000 years ago during the Medieval Warm Period.
Isn’t climate change making floods more severe?
In addition, a recent study by the U.S. government found no evidence that climate change caused more severe flooding during last century. In fact, the U.S. Geological Survey found that in some regions “floods become less severe as greenhouse gas emissions increased.” Moreover, at this time, “we do not see a clear pattern that enables us to understand how climate change will alter flood conditions in the future,” USGS scientist Robert Hirsch explained.
Aren’t hurricanes getting bigger, stronger and more frequent due to man-
No. Major hurricanes are now less frequent. Not a single decade during past 50 years
witnessed an above-
The worst decade for major (category 3, 4 and 5) hurricanes was the 1940s, according to the website Real Science which analyzed National Oceanic and Atmospheric Administration data. In 2011, a new study found that “overall global tropical cyclone activity has decreased to historically low levels during the past five years.”
Isn’t global warming causing bigger more dangerous tornadoes?
No. In fact, big tornadoes have seen a drop in frequency since the 1950s. “There has been a downward trend in strong (F3) to violent (F5) tornadoes in U.S. since 1950s.” In fact, “warming causes fewer strong tornadoes, not more,” climatologist Dr. Roy Spencer explained.
Other prominent scientists also reject global warming links to tornadoes. There is “no scientific consensus or connection between global warming and tornadic activity,” emphasized Greg Carbin, tornado warning coordination meteorologist at NOAA’s Storm Prediction Center in Norman, Oklahoma. “NOAA statistics show that the last 60 years have seen a dramatic increase in the reporting of weak tornadoes, but no change in the number of severe to violent ones,” Corbin commented.
Aren’t wildfires getting worse?
No. “Data from both U.S. and Canada show the number of wildfires has declined over
the past 40-
Spanish researchers confirmed climate change not to blame for increased forest fires. “The change in the occurrence of fires that are recorded in the historical research cannot be explained by the gradual change in climate,” they reported. Instead, it “corresponds to changes in the availability of fuel, the use of sources of energy and the continuity of the landscape.” In the United States, wildfires are also due to a failure to thin forests or remove dead and diseased trees – due largely to environmentalist protests and lawsuits.
Don’t we need to stop global warming to keep cities from being inundated by rising seas?
Sea levels have been rising since the last ice age ended 10,000 years ago. There
is currently no acceleration in sea level rise. The National Oceanic and Atmospheric
Administration says sea level is rising very slowly, and a recent peer-
Aren’t Polar bears dying and threatened with extinction by receding Arctic ice?
No. Polar bears are at or near historic population highs. The only threats they face are from virtual world computer model predictions that do not reflect reality or account for the adaptability of these animals.
“The only reason the service listed them was based on speculation from fairly untested models, based on what the fate of polar bears may be in the future,” perhaps if global warming ever dramatically alters the bears’ habitat, Alaska’s coordinator for endangered species explained.
The polar bear population is very, very healthy,” Canadian Inuit have emphasized. “We live in polar bear country. We understand the polar bears. We are unanimous in our belief that polar bears have not declined.”
Evolutionary biologist and paleozoologist Dr. Susan Crockford of the University of
Victoria agrees. “Polar bears have survived several episodes of much warmer climate
over the last 10,000 years than exists today,” she wrote. “There is no evidence to
suggest that the polar bear or its food supply is in danger of disappearing entirely
with increased Arctic warming, regardless of the dire fairy-
University of Iceland professor and award-
Professor J. Scott Armstrong, a forecasting expert at the Wharton School says polar bear models are critically flawed. “To list a species that is currently in good health as an endangered species requires valid forecasts that its population would decline to levels that threaten its viability. In fact, the polar bear populations have been increasing rapidly in recent decades, due to hunting restrictions.
Biologist Josef Reichholf heads the Vertebrates Department at the National Zoological Collection in Munich. “In warmer regions, it takes far less effort to ensure survival,” he points out. “How did the polar bear survive the last warm period? Whether bears survive will depend on human beings, not the climate.”
Don’t graphs show that current temperatures are the highest in 1,000 years?
Penn State professor and UN IPCC modeler Michael Mann did publish a hockey stick-
The latest research clearly reveals that the Medieval Warm Period (also called the Medieval Climate Optimum) has been verified and was in fact global, not just confined to the Northern Hemisphere. The Center for the Study of Carbon Dioxide and Global Change reported in 2009 that “the Medieval Warm Period was: (1) global in extent, (2) at least as warm as, but likely even warmer than, the Current Warm Period, and (3) of a duration significantly longer than that of the Current Warm Period to date.”
The Science and Public Policy Institute reported in May 2009: “More than 700 scientists
from 400 institutions in 40 countries have contributed peer-
Weren’t the Climategate scientists exonerated – meaning there was no scandal?
Many in the media repeatedly cite the various Climategate investigations as an “exoneration” of the UN global warming scientists. But a closer look reveals that the investigations were nothing more than the global warming industry pretending to investigate itself, and of course pretending to find no wrongdoing.
Penn State’s investigation of Michael Mann is a prime example of what a mockery the process became. Clive Crook of the Atlantic Monthly summed it up this way: “The Penn State inquiry exonerating Michael Mann would be difficult to parody. Three of four allegations were dismissed out of hand at the outset.”
Why do you oppose government taking steps to solve the climate crisis?
Despite all the evidence and studies presented in this paper, many people continue to say that Congress and the United Nations need to take immediate action to prevent more extreme weather, rising sea levels and planetary “overheating.” The reality is that politicians who say government “can do something about” droughts, floods, sea levels, hurricanes and tornadoes are practicing the equivalent of medieval witchcraft.
Laws, treaties and regulations – whether from the United Nations, U.S. Congress or Environmental Protection Agency, cannot control the weather. CO2 does not control global temperatures, and current global temperatures are well within natural variability, as demonstrated by surface and satellite data and extensive historic records. Scientific studies and data also show that droughts, floods and wildfires and extreme weather are not unusual, unprecedented or related to CO2 emissions or climate change.
Shouldn’t Congress pass a cap-
The climate bill that died in the Democrat Senate was a scientifically meaningless bill that Obama’s own EPA admitted would not impact global CO2 levels – let alone global temperatures.
The climate bill would only have raised the cost of energy for American families and businesses, while doing nothing for the climate. A major Bloomberg News report revealed that U.S. oil companies would likely cope with the climate legislation by “closing fuel plants, cutting capital spending and increasing imports.” Bloomberg also reported that “one in six U.S. refineries probably would close by 2020,” and this could “add 77 cents a gallon to the price of gasoline.”EPA’s unilateral “carbon dioxide endangerment” regulations would have much the same effect.
