The IPCC’s AR5 estimated the global warming caused by a tonne of livestock methane would be 28 times that of a tonne of carbon dioxide. New research destroys that estimate. The war on meat has been gathering pace amongst our Western elites. The Economist makes a detailed case for “plant-based food” in the interests of quelling climate change – The FAO calculates that cattle generate up to two-thirds of the greenhouse gases from livestock, and are the world’s fifth largest source of methane. If cows were a country, the United Herds of Earth would be the planet’s third largest greenhouse-gas...

There goes another “fingerprint”… It’s not just that man-made emissions don’t control the climate, they don’t even control global CO2 levels. Judging by the speech Murry Salby gave at the Sydney Institute, there’s a blockbuster paper coming soon.Listen to the speech: “Global Emission of Carbon Dioxide: The Contribution from Natural Sources”Professor Murry Salby is Chair of Climate Science at Macquarie University. He’s been a visiting professorships at Paris, Stockholm, Jerusalem, and Kyoto, and he’s spent time at the Bureau of Meterology in Australia. Over the last two years he has been looking at C12 and C13 ratios and CO2 levels...

Simple Chemistry and the Real Greenhouse Effect. Truths: 1. Most of the Sun’s radiation that gets to the Earth’s lower atmosphere passes through substantially unabsorbed. 2. Most of the radiation is then absorbed on contact with the Earth’s surface. This includes the majority water and the minority land. 3. Most of the Earth’s surface is either water or moist vegetation. Most of the radiation from the sun is converted to infrared wavelengths at or near the surface. The water molecules absorb the infrared radiation causing increased vibration within the individual water molecules. This is converted into translational energy during intermolecular...

Actually, the records of temperature and CO2 over the past 650,000 years indicate that Earth's temperature always rises first, followed by a rise in Carbon Dioxide. Published papers, clearly show it is always temperature which rises first by at least several hundred years and then the carbon dioxide responds.

America’s energy sources, like booming oil and crumbling coal, have defied projections and historical precedents over the last decade. ... unexpectedly, ... In 2010, the U.S. Energy Information Administration projected that in 2019, the U.S. would be producing about six million barrels of oil a day. The reality? We're now producing 12 million barrels of oil a day. Meanwhile, EIA projected oil prices would be more than $100 a barrel. They're currently hovering around $60 a barrel. What’s happening: A pair of extraction methods — horizontal drilling and hydraulic fracturing — have unlocked far more oil and gas than experts...

Silver bullet to hit us allMikhail Voytenko November 13, 2019 4:09 am A silver bullet hits shipping, killing everything on its’ path, in form of new research commissioned by campaign groups Seas At Risk and Transport and Environment. “Speed reduction is the closest thing to a silver bullet the IMO will ever see,” said Seas at Risk’s senior policy advisor John Maggs. “We’ve got a win from a climate point of view, we’ve got a win from a human health point of view, we’ve got a win for marine nature, we’ve got a potential safety gain, and up to a...

NASA’s Curiosity rover returned some seriously surprising data to Earth earlier this year, with readings of elevated methane levels that were hard to explain. Subsequent tests attempted to pin down the cause of the higher-than-expected readings but scientists have yet to come up with a definitive answer. Now, as questions about methane continue to swirl, scientists studying the behavior of gasses on Mars have noticed that oxygen on the Red Planet also acts much differently than it does on Earth. The observations were made in the Gale Crater, which the rover has called home since it landed there back in...

Despite the ever present wailing from green activists that we are sitting on a “methane catastrophe”, it’s simply business as usual for Earth in the Arctic. Even Dr. Gavin Schmidt of NASA GISS thinks the issue is “implausible”. This study further confirms that the issue is just another emotional overblown green issue of no merit.Methane seepage from the Arctic seabed occurring for millions of yearsFrom the Center for Arctic Gas Hydrate, Climate and EnvironmentMethane gas flares, up to 800 meters high, rise from the Arctic Ocean floor. That is the size of the tallest building in the world, Burj...

During the past 2.6 million years, Earth’s climate has alternated between warm periods known as interglacials, when conditions were similar to those of today, and cold glacials, when ice sheets spread across North America and northern Europe. Before about 1 million years ago, the warm periods recurred every 40,000 years, but after that, the return period lengthened to an average of about 100,000 years. It has often been suggested that a decline in the atmospheric concentration of carbon dioxide was responsible for this fundamental change. Writing in Nature, Yan et al.1 report the first direct measurements of atmospheric CO2 concentrations...

The process could work on the gas at any concentrations, from power plant emissions to open air. A new way of removing carbon dioxide from a stream of air could provide a significant tool in the battle against climate change. The new system can work on the gas at virtually any concentration level, even down to the roughly 400 parts per million currently found in the atmosphere. Most methods of removing carbon dioxide from a stream of gas require higher concentrations, such as those found in the flue emissions from fossil fuel-based power plants. A few variations have been developed...

We actually do not know how much carbon dioxide was in Earth’s atmosphere prior to the 1930s. Devices to reliably measure carbon dioxide in the air went through painstaking, slow, bumpy development. Instruments did not really come into their own until around 1930. Because we don’t know the carbon dioxide content of the atmosphere, climate change proponents depend upon unreliable “proxies.” They substitute gas pockets retrieved from ice core samples from deep within ancient glaciers. They hope this will tell us Earth’s ancient atmosphere and the concentration of CO2 in the air. Speculation that air pockets remain exactly the same...

We do not know how much carbon dioxide was in Earth's atmosphere prior to the 1930s. Devices to measure carbon dioxide went through a difficult, slow, irregular development. Reliable devices to measure carbon dioxide were available around 1930. "The measurement of carbon dioxide (CO2) was first developed in the early 1900s; however, it was complex and of limited clinical use. " See: Thomas Nowicki; Shawn London, "Carbon Dioxide Detector," National Center for Biotechnology Information. The technology was slowly developed and produced a useable machine only around the year 1930. Guy Stewart Callendar -- who dreamed up the global warming scare...

The Boknis Eck Observatory might've been "forcibly removed" from a bay in Germany, the GEOMAR Helmholtz Centre for Ocean Research in Kiel said. Data transmission from the underwater sensors suddenly cut out one night in August, GEOMAR said. When divers went to investigate at the observatory site, they found nothing but a shredded cable that once anchored it. The observatory, planted in Kiel's Eckernförde Bay in 2016, consists of two "desk-sized" racks: One acts as a power source, tethered to the coast by a cable, and the other contains the sensors that transmit data back to shore. Both were missing...

Forcing America to install literally millions of wind turbines and tens of millions of solar panels, and plant tens of millions more acres in biofuel crops, would devastate wildlife habitats and countless species, while driving up electricity prices for families, factories, farms, businesses, schools and hospitals. The wind and sunlight may be free, clean and green. But the massive technologies required to harness those forces for human benefit certainly are not. If Trump Administration advisors thought they could appease their opponents by implementing a rule focused on the useless and ultimately dangerous goal of limiting CO2 emissions, they were sorely...

Scientists have found that increasing oxygen levels are linked to the rise of North American dinosaurs around 215 M years ago. A new technique for measuring oxygen levels in ancient rocks shows that oxygen levels in North American rocks leapt by nearly a third in just a couple of million years, possibly setting the scene for a dinosaur expansion into the tropics of North America and elsewhere... The US-based scientists have developed a new technique for releasing tiny amounts of gas trapped inside ancient carbonate minerals. The gases are then channelled directly into a mass spectrometer, which measures their composition....

Last month, carbon dioxide levels in the atmosphere surpassed 415 parts per million, the highest in human history. Environmental experts say the world is increasingly on a path toward a climate crisis. The most prominent efforts to prevent that crisis involve reducing carbon emissions. But another idea is also starting to gain traction — sucking all that carbon out of the atmosphere and storing it underground. It sounds like an idea plucked from science fiction, but the reality is that trees and plants already do it, breathing carbon dioxide and then depositing it via roots and decay into the soil....

In December 2009, the Obama Environmental Protection Agency issued its Endangerment Finding (EF) – decreeing that carbon dioxide (CO2) and other “greenhouse gases” (GHGs) endanger the health and welfare of Americans. In the process, EPA ignored the incredible economic, health and welfare benefits of fossil fuels – and the fact that (even at just 0.04% of the atmosphere) carbon dioxide is the miracle molecule that enables plants to grow and makes nearly all live on Earth possible. EPA turned CO2 into a “dangerous pollutant” and ruled that fossil fuels must be eradicated. The agency subsequently used its EF to justify...

In direct contradiction to the scare stories about carbon dioxide being relentlessly pushed by the climate change alarmists, a scientific study published in Nature Climate Change and highlighted by NASA reveals that rising carbon dioxide levels are having a tremendously positive impact on the re-greening of planet Earth over the last three decades, with some regions experiencing over a 50% increase in plant life.The study, entitled, “Greening of the Earth and its drivers,” used satellite data to track and map the expansion of green plant growth across the globe from 1982 – 2015. Published in 2016, this study found that rising atmospheric carbon...

For several million years, the Earth cycled through ice ages at a regular pace, but then, 1.25 million to 700,000 years ago, something changed: ice ages went from lasting 40,000 years to 100,000. … By looking at the microscopic shells of microorganisms called foraminifera, Adam Hasenfratz of the Geological Institute in Zürich, Switzerland, and colleagues, find evidence of a reduction in deep water circulation, causing less carbon dioxide to be released into the air. Oceanic changes in the Antarctic Zone could have ensured “that glacial conditions persisted despite orbital changes to the contrary”, the study says. The new research, presented...

Loren Poncia scooped up a handful of dark, damp soil that could change the future of farming. The nutrient-rich muck was filled with slithery earthworms and thin, white roots sprouting in every direction like lightning bolts. “This is the carbon farmer’s dream,” he exclaims. “We want to see like 10 worms in a shovel-full.”
