Over 4,000 years ago, the Harappan Civilization of the Indus Valley faded and disappeared. Never heard of the Harappans? Theirs was a Bronze-Age civilization located where Pakistan and northwest India are today. With large, well-planned cities, municipal sewage systems and writing that has never been deciphered, they had a civilization equal to Egypt, Mesopotamia, and Greece. But the Harappans fell victim to what most view as a modern horror—climate change. Sometime around 2,100 BC the monsoon cycle, vital to all of South Asia, faltered. The reliable rains stopped, and man's earliest civilizations fell. Now we are told that California—that progressive paradise on the Pacific—is poised on the brink of its own drought spawned disaster. So desperate have things become that one restaurant chain has threatened to stop serving guacamole and vintners are turning to witchcraft. Can the total collapse of Californian civilization be far behind?
California, the state that raises 30% of US fresh produce, is in the grip of a severe drought. Billed as the driest period in the state's recorded rainfall history, climate change alarmists have hastened to blame the parched conditions on anthropogenic global warming (AGW). Paleoclimate history tells a different story, however, and highlights the amazingly short attention span of AGW advocates. Going beyond the 163-year historical period, science shows that there have been other, longer lasting and more severe droughts than the current dry spell. Today's drought is minor when compared with ancient Megadroughts, which occurred between 850 to 1090 and 1140 to 1320. In fact, the worst droughts suffered by the American Southwest all happened so long ago that human memory fails us.
You may have notice that the news media talking heads and TV weather presenters have discovered a new term recently—the Arctic Vortex. In a splendid demonstration of how the weak minded are quickly consumed by group think, and ill understood terms get repeated ad nauseum, the Arctic Vortex has dominated the news during the past week in the US. In truth, the phenomenon is not new. What is new is that its current foray south is being loudly attributed to global warming. For years the effects of a warming Arctic have been the subject of scientific speculation. Dubbed Arctic amplification, some claim it will enhanced extreme weather in the middle latitudes. The fact that such linkage is tenuous at best has not stopped ignorant politicians like the UK's David Cameron and the US's Barack Obama from blaming recent nasty weather on that old nugget, anthropogenic global warming. There is, however, some evidence to the contrary from one scientist who studies atmospheric dynamics and variability under different climates.
All of us here at The Resilient Earth wish our readers the happiest of New Years. As you all probably know, 2013 was not the best of years for the global warming backers of the world. In the US, we have experienced the lowest number of tropical storms, tornadoes and wild fires in decades. The year past saw more record lows set than record highs and drought conditions eased in many places. While this does not disprove the global warming hypotheses, all those factors were cited by AGW proponents as outcomes of rising global temperatures. The fact that the opposite of the warmists' predictions have taken place weakens the theory and casts doubt on the whole climate change scam. Given that both North America and Europe are in the grip of frigid winter temperatures it is an AGW true believer indeed who continues to insist the world is getting hotter.
Unless you have been living in one of the few truly remote areas of the planet, you have been exposed to them. Climate change memes that pass from person to person and are repeated without thought or critical examination. They range from the subtle—bad weather is being increased by global warming—to the banal—over 97% of scientists agree about climate change. We are bombarded with these unsubstantiated ideas over and over again, from talking heads on TV, newspaper headlines, our friends and even the president of the United States. They are blatant untruths that have become legitimized by repetition, until school children and adults alike patriot them to each other. The recent tropical cyclone, Haiyan, has triggered another round of meme infection: it was the worst storm in history, tropical storms are getting bigger every year, there are more storms every year, and, of course, they are all caused by global warming. Trouble is, these “facts” are all false.
The long awaited full text report is finally available. The Final Draft Report, dated 7 June 2013, of the Working Group I contribution to the IPCC Fifth Assessment Report Climate Change 2013: The Physical Science Basis was accepted but not approved in detail by the Twelfth Session of Working Group I and the Thirty-Sixth Session of the IPCC on 26 September 2013 in Stockholm, Sweden. This report consists of the full scientific and technical assessment undertaken by Working Group I. While the final draft of the underlying Working Group I report is still subject to copy-editing and corrections in proof as normally applied to scientific reports the fundamental tone and content of the report has been set. No screaming warnings; no predictions of impending doom. The most shocking thing is that our knowledge of climate change has not advanced in almost a decade. Simply put, climate scientists are puzzled by the way nature is acting.
Much has been done to vilify carbon dioxide in the media. Listening to the talking heads and on-air “experts” could lead one to believe that CO2 is an evil scourge that the world would be better off without. Nothing could be further than the truth. CO2 is necessary for life on Earth, forests in particular. It is not just plant food, the maligned gas also plays a role in regulating water use by the world's forests. New research has uncovered an unexpectedly strong decrease in H2O uptake caused by increasing CO2. Along with global increases in photosynthesis, forest growth rates, and carbon uptake, higher CO2 levels contribute to enhanced timber yields and improved water availability. Who says higher CO2 levels are a bad thing?
The threat of widespread and persistent drought, ruining crops and threatening water supplies, is constantly cited as an outcome of global warming. Media talking heads, climate scientists (who should know better) and even the American President have all made this assertion—and there is nothing to back up the claim. Results presented recently at the annual assembly of the European Geosciences Union in Vienna show that forecasting drought is still beyond the reach of current climate models. Models run against historical data have either predicted periods of drought at the wrong times or missed them all together. Yet climate alarmists continue to spread this pernicious lie, preaching damnation with the certitude of an Old Testament prophet.
Since it was recently Earth Day, a yearly day of celebration and protest by conservationists and assorted greens, it is instructive to take a look at a number of recent studies taken from the scientific literature. The dire predictions made by climate change alarmists are many, far to numerous to all be addressed here, so this article will examine three areas of concern: increased drought, destruction of the world's rainforests, and the die-off of ocean coral reefs. Each of these reported calamities has been linked to increasing anthropogenic greenhouse gas emissions and that supposed bane of nature, anthropogenic global warming (AGW). These threats have been repeated ad nauseum by talking heads and climate change activists, but the truth is that these predicted outcomes are not as threatening as they would have you believe.
It's everywhere on Earth, on the other planets and moons of the solar system, and even in comets from deep space. It is the frozen form of water, commonly called ice. Something so ubiquitous and familiar, one would think that science knows a lot about ice. It turns out science knows less than we might suppose. In a commentary in the journal Nature, an ice scientist raises ten open questions about ice. For example, the article states: “We cannot predict with certainty when and where ice clouds will form in the atmosphere; areas of the sky remain humid when we would expect them to freeze.” Ice is a fundamental part of Earth's climate, yet these questions and others remain unanswered. How can climate science claim to predict the fate of the polar ice sheets or mountain glaciers when we do not really understand the substance that they are made of?
A newly released study from the Research Council of Norway has climate change alarmists abuzz. One of the things the alarmists have been pushing for is to halt warming at a 2°C increase at any cost (and they mean that literally). In the Norwegian study, much to the alarmists' dismay, researchers have arrived at an estimate of 1.9°C as the most likely level of future warming. The report also recognizes that temperatures have stabilized at 2000 levels for the past decade even though CO2 levels have continued to rise. Meanwhile, a reconstruction of the Eemian interglacial from the new NEEM ice core, published in the journal Nature, shows that in spite of a climate 8°C warmer than that of the past millennium, the ice in Northern Greenland was only a few hundred meters lower than its present level. This finding casts doubt on the projected melting of ice sheets and resulting sea-level rise.
The Intergovernmental Panel on Climate Change (IPCC) has consistently predicted expanding world wide drought as one of the horrors of global warming. New research suggests that things may not be quite as arid as they predicted. According to scientists, a commonly used technique for estimating drought severity may actually overestimate the effects of dry spells. Revisiting historical data for the period 1980-2008, a new assessment technique found that the global area stricken by drought grew by approximately 0.08% per year—less than one-seventh (14%) the increase previously reported. Moreover, researchers found that drought causes higher temperatures, not the other way around. Once again, the horrendous effects of anthropogenic global warming have been found to be over hyped by the self-serving savants of the IPCC.
In a mad rush to prove who can put out the most inane press release, various warm-mongers, news hacks and climate alarmists have gone on a predictable spree, trying to blame Hurricane Sandy and the resulting disaster in the US Northeast on CO2 levels. Who are these clowns? Even the IPCC issued a statement saying that global warming was not to blame. Have none of these empty headed blatherskites noticed that it has been more than seven years since a major hurricane struck the US, the longest such period since the Civil War? Evidently not, since they continue to spew unscientific twaddle and the news media continues to lap it up like a dog eating its own vomit.
Most Americans have noticed that the price of gasoline at the pump has started to rise again. Gasoline prices have surged 30 cents since mid-July and now average $3.70 a gallon, higher than year-ago levels in 39 states. While some sources have blamed the recent refinery fire in California and others a rise in crude oil prices there is one hidden source of increasing fuel costs few are willing to mention—ethanol. Mandated by Congress to make up 10% of automotive gasoline, ethanol made from corn accounts for a quarter of recent fuel price increases while at the same time contributing to rising food costs and shortages world wide. Not satisfied with this astounding government largess, an unnatural alliance of eco-activists and big agribusiness is lobbying to raise the mandate to 15%. It is time for this blatant government kickback to end.
Between 15 and 20 million years (Myr) ago, Earth's climate took a pause during its long slide into the Pleistocene Ice Age for a period of real global warming. During this relatively brief time glaciers around the world retreated and there are indications that, at least around the edges of the continent, there was significant vegetation on Antarctica. Temperatures may have been as high as 11°C higher than today. Scientists say this global warm spell took place under under CO2 levels in the range of 190–850 ppmv, both significantly higher and lower than today's 390 ppmv. It is hoped that studying conditions during the Miocene warming can provide constraints on the fundamental laws governing the climate system. Why? If the Pleistocene Ice Age is truly coming to an end, as some have said, this may be the climate of the future.
