After half a billion million years of climate change, I’m shocked, shocked I tell you, that life on Earth (and specifically corals) have so many ways to cope with the climate changing. After all, it’s natural (if you are trained by Greenpeace) to assume that corals can only survive in a world with one constant stable temperature just like they never had.

The Kremlin has masterminded an elaborate scheme to undermine American fossil-fuel production and distribution, concludes a report by the U.S. House Committee on Science, Space, and Technology.
Released March 1, the report, “Russian Attempts to Influence U.S. Domestic Energy Markets by Exploiting Social Media,” reveals how Russia has teamed up with U.S. and European environmental groups to use such popular outlets as Facebook, Twitter, and Instagram to turn American public opinion against the domestic oil and natural gas industry.
With the United States having surpassed Russia as the world’s largest producer of natural gas, and now ranking as the world’s fastest-growing producer of oil, the Russians have reason to fear what is more than a little competition. Saying America’s soaring energy development “poses a direct threat to Russian energy interests,” the report explains: …

Global climate change, fueled by skyrocketing levels of atmospheric carbon dioxide, is siphoning oxygen from today’s oceans at an alarming pace — so fast that scientists aren’t entirely sure how the planet will respond.
Millions of years ago, scientists discovered, powerful volcanoes pumped Earth’s atmosphere full of carbon dioxide, draining the oceans of oxygen and driving a mass extinction of marine organisms.

A tiny clue found in ancient sediment has unlocked big secrets about Greenland’s past and future climate.
Just beyond the northwest edge of the vast Greenland Ice Sheet, Northwestern University researchers have discovered lake mud that beat tough odds by surviving the last ice age. The mud, and remains of common flies nestled within it, record two interglacial periods in northwest Greenland. Although researchers have long known these two periods — the early Holocene and Last Interglacial — experienced warming in the Arctic due to changes in the Earth’s orbit, the mix of fly species preserved from these times shows that Greenland was even warmer than previously thought.

The global increase in the atmosphere’s CO2 content has been hypothesized to possess the potential to harm coral reefs directly. By inducing changes in ocean water chemistry that can lead to reductions in the calcium carbonate saturation state of seawater (Ω), it has been predicted that elevated levels of atmospheric CO2 may reduce rates of coral calcification, possibly leading to slower-growing — and, therefore, weaker — coral skeletons, and in some cases even death.
As we have previously pointed out on our website, however (see The End of the Ocean Acidification Scare for Corals and A Coral’s Biological Control of its Calcifying Medium to Favor Skeletal Growth), such projections often fail to account for the fact that coral calcification is a biologically mediated process, and that out in the real world, living organisms tend to find ways to meet and overcome the many challenges they face; and coral calcification in response to ocean acidification is no exception.

It has long been established in the scientific literature (and affirmed by the IPCC) that CO2 concentration changes followed Antarctic temperature changes by about 600 to 1000 years during glacial-interglacial transitions throughout the last ~800,000 years (Fischer et al., 1999; Monnin et al., 2001; Caillon et al., 2003; Stott et al., 2007; Kawamura et al., 2007).
In contrast, two new papers cite evidence that the timing of the lagged CO2 response to temperature changes may have ranged between 1300 and 6500 years in some cases. It would appear that a millennial-scale lagged response to temperature undermines the claim that CO2 concentration changes were a driver of climate in the ancient past.

On June 8th, the California Department of Forestry and Fire Protection (Cal Fire) made its first official announcement via press release that 12 big Northern California wildfires in October 2017 were caused by problems associated with electric utility power lines.
The October 2017 Fire Siege involved more than 170 fires and burned at least 245,000 acres in Northern California. About 11,000 firefighters from 17 states and Australia helped battle the blazes. They concluded that 12 Wildfires in Mendocino, Humboldt, Butte, Sonoma, Lake, and Napa Counties were caused by Pacific Gas & Electric (PG&E) “power and distribution lines, conductors and the failure of power poles.”
The words “global warming” and “climate change” were conspicuously absent from the announcement even…

Solar cycle 24 is ending and we are approaching a time of minimal solar activity between solar cycles 24 and 25, known as a solar minimum. Despite claims that we understand how the Sun works, our solar predictive skills are still wanting, and the Sun continues to be full of surprises.
The surprising 2008 solar minimum
Solar scientists did not pay much attention to the early warning signs that the Sun was behaving differently during solar cycle 23 (SC23), and to most the surprise came when the expected solar minimum failed to show up in 2006. The SC23-24 minimum took place two years later (Dec 2008, according to SIDC), and despite showing only a tiny difference in total solar irradiation compared to previous minima of the space age, it displayed significantly reduced solar wind speed and density, extreme-UV flux was 10% reduced, the polar fields were 50% smaller, and the interplanetary magnetic field strength was 30% below past minima.

Trois révolutions énergétiques depuis à peine plus d’un siècle. Nous sommes entrés dans la troisième révolution énergétique. La première vit le jour avec la machine à vapeur et participa à l’essor du charbon, avec la seconde le moteur thermique dérôna le charbon au profit des hydrocarbures, et la troisième révolution industrielle, en cours, est technologique et basée sur les énergies ‘vertes’ ou énergies intermittentes et l’informatique ou le numérique. Cette problématique vient d’être abordée dans un excellent ouvrage paru en 2018 .
Peut-on dire que cette progression récente suivant ces trois phases majeures de la technologie s’est effectuée dans le sens d’un meilleur respect de l‘état de la Planète. Bien que cela soit le discours officiel, rien n’en est moins sûr. Pourquoi ? Tout simplement par le méconnaissance de tout un chacun à comprendre ou savoir ce qui est réellement utilisé dans les énergies vertes et numériques. L’actuelle ‘transition énergétique’ a bon dos et elle a toutes les vertus, elle est propre, quant aux les hydrocarbures, le charbon, l’uranium et CO2 (ennemi n° 1) ils ont tous les maux, et sont tous sales. Il n’est pas un jour où cette opposition nous est rappelée…

More excuses for “the pause”.
A team of researchers from the U.K. Met Office, Sweden and Australia has found that three periods of global warming slowdown since 1891 were likely due to natural causes rather than disruptions to the factors causing global warming. In their paper published on the open access site Science Advances, the group describes their study of global mean surface temperatures (GMST) since the late 19th century and what they found.
In this new paper, the researchers looked at GMST as registered by multiple sources around the globe over the past 127 years, noting the slow march of temperature increases. More specifically, they noted the three previously identified slowdowns in GMST increases—the time periods from 1896 to 1910, from 1941 to 1975, and then from 1998 to 2013. They then looked at factors that could have contributed to these slowdowns and found natural causes for each. (…)

The following true story is a cautionary tale for scientists against making quick judgements about what seems impossible. Or indeed for any “experts” believing that they know best and ignoring any evidence contrary to what they believe. Does this ring any bells relating to the global warming hypothesis?

We have mentioned countless times on this blog that the warming oceans are evidence that CO2 is not the cause of global warming. To understand the climate you must first understand the oceans. The oceans control the global climate. As the oceans warm, they warm and alter the humidity of the atmosphere above them. The problem is, as we have pointed out countless times, CO2’s only defined mechanism by which to affect climate change is through the thermalization of LWIR between 13 and 18µ.
LWIR between 13 and 18µ doesn’t penetrate or warm the oceans. Visible radiation, mainly from the high energy blue end of the spectrum does. CO2 is transparent to incoming visible radiation. The energy stored in the atmosphere and land is insignificant when compared to the oceans. The oceans contain 2,000x the energy of the atmosphere, so small changes to the oceans can mean big changes in the atmospheric temperature. The oceans also produce vast amounts of CO2 (20 x the amount man produces), and the most abundant and potent greenhouse gas, water vapor.
