GR: It’s not all of humankind that is responsible for the great danger we face, It’s particular members of the species. The fossil fuel companies in America and Europe fooled most of us into thinking that unlimited coal and oil burning was safe. Are we just as guilty as Rex Tillerson and the other energy industry leaders who lied to us, or does our ignorance and gullibility make our behavior excusable? Perhaps. However, continuing to believe Rex Tillerson’s Exxon-Mobil deceit with so many scientists and independent voices calling out the warning is criminal negligence.

Conservative climatologists such as Robert Scribbler have sought to avoid projecting alarmist images. However, in the article below Scribbler does not shy away from discussing the real possibility of human-caused mass extinction. We can still avoid our extinction, but if we fail to use our brains and heed the warnings of our scientists and thinkers, our punishment will be extreme.

Paul Beckwith recently reported that fossil fuel use appears to be rising instead of falling. Read his article to see what he discovered.

“Over recent years, concern about a coming hothouse mass extinction set off by human carbon emissions has been on the rise. Studies of Earth’s deep history reveal that at least 4 out of the 5 major mass extinctions occurred during both hothouse periods and during times when atmospheric and oceanic carbon spiked to much higher than normal ranges. Now a new scientific study reveals that we are have already emitted 50 percent of the carbon needed to set off such a major global catastrophe.

Fossil Fuel Burning = Race Toward a 6th Mass Extinction

“The primary driver of these events is rising atmospheric CO2 levels — often caused in the past by the emergence of masses of volcanoes or large flood basalt provinces. In the case of the worst mass extinction — the Permian — the Siberian flood basalts were thought to have injected magma into peat and coal formations which then injected a very large amount of carbon dioxide into the Earth’s atmosphere and oceans.

“Higher atmospheric and ocean carbon drove both environmental and geochemical changes — ultimately setting off hyperthermal temperature spikes and ocean anoxic events that were possibly assisted by methane hydrate releases and other climate and geophysical feedbacks. The net result of these events was major species die-offs in the ocean and, during the worst events, on land.

“Considering the fact that present human activities, primarily through fossil fuel burning, are releasing vast quantities of carbon into the Earth’s atmosphere and oceans at a rate never before seen in the geological past, it appears that the world is racing toward another major mass extinction. In the past, the location of this dangerous precipice was a bit murky. But a recent study in Science Advances attempts to better define the threshold at which the worst of the worst mass extinction events — set off by rising ocean and atmospheric carbon — occur.

310 Billion Tons Carbon Entering Ocean = Mass Extinction Threshold

“The study used a relatively easy to identify marker — ocean carbon uptake — in an attempt to identify a boundary limit at which such mass extinctions tend to occur. And the study found that when about 310 billion tons of carbon gets taken in by the oceans, a critical boundary is crossed and a global mass extinction event is likely to occur.

“Presently, human beings are dumping carbon into the atmosphere at an extremely high rate of around 11 billion tons per year. Today, about 2.6 billion tons per year of this carbon ends up in the ocean. In total, since 1850, humans have added about 155 billion tons of carbon to the Earth’s oceans — leaving us with about another 155 billion tons before Rothman’s (the study author) extinction threshold is crossed.” –Robert Scribbler (Continue reading and review the graphs: Half-way to Catastrophe — Global Hothouse Extinction to be Triggered by or Before 2100 Without Rapid Emissions Cuts.)| robertscribbler
