Climate change terror

The Dubai’s COP-out denial conference
- by Andrew Glikson -

The issue, betrayed, is nothing more and nothing less than the future of a multitude of species on Earth, including Homo sapiens.

As confirmed by the acceleration of climate extremes, consistent with the prediction by Wallace Broecker, the authoritative climate scientist, global climate change is racing beyond tipping points (Figure 1), yet the evidence continues to be denied, including in the recent COP-28 climate conference, where climate scientists are almost nowhere to be seen.

Figure 2a. Based on NOAA’s temperature data Earth’s temperature rose by an average of 0.08° C per decade since 1880; Since 1981 the warming rate is 0.18° C per decade. The 2022 surface temperature was 0.86 °C warmer than the 20th-century average of 13.9 °C and 1.06 ˚C warmer than the pre-industrial period (1880-1900). The 10 warmest years in the historical record have all occurred since 2010.

As temperatures rise (Figure 2a), fires engulf large tracts of land, storms intensity and sea levels rise (Figure 2b), the living Earth is entering a critical stage. Having ignored the existential threat of climate change, extreme nationalism and fascism ─ the ideology of death ─ spill rivers of blood in many parts of the world.

While the powers that be ─ politicians, CEOs, top-bureaucrats, economists and their media mouthpieces ─ proceed to propagate dangerous lies, such as the denial of climate change at the heart of the Dubai COP-28 conference.

A principal lie is that, in itself, the application of clean technologies ─ solar, wind, tide, hydrogen, may be sufficient to arrest global warming. Likewise, ignoring the export of fossil fuels in national carbon inventories, despite the dissemination of greenhouse gas emissions world-wide.

Major climate untruths propagated by governments, fossil fuel corporations and their subservient media include proposed limits on domestic emissions which are meaningless to the arrest of global warming since with continuing mining, export and combustion of fossil fuels, greenhouse gases disperse through the atmosphere regardless of where the fossil fuel is mined or burnt.

With CO₂ level reaching 418.51 ppm at a rate of ~2.5 ppm/year and methane CH₄ level reaching 1917.1 ppb at a rate of near-12 ppb per year, greenhouse gas rises are exceeding any in recent geological history, representing the most severe atmospheric crisis since the asteroid impact which killed the dinosaurs 66 million years ago. Oblivious to the physical laws on which climate science is based and to the time factor of the impending climate crisis, setting artificial targets such as “1.5°C by 2030” or “2°C by 2050”, the powers-to-be may not be aware of what life on planet Earth is facing.

Australia is the world’s third biggest exporter and fifth biggest miner of fossil fuels by CO₂ potential. hydrocarbon exports, following Russia and Saudi Arabia. “The government denies responsibility for emissions created by the vast amounts of coal and gas Australia exports overseas as one of the world’s largest fossil fuel producers, and has flatly ruled out any discussion on banning new fossil fuel projects” (McNeill, 2022).

While ongoing combustion of fossil fuels is raising greenhouse gas concentration at a rate unprecedented in the geological record, global heating being a self-amplifying process, the utilization of clean energy: solar, wind, hydropower and thermal power cannot by itself stem global warming, now rising above 420 ppm CO₂, well above the 180-280 ppm range of the preceding glacial-interglacial cycles. Such a high CO₂ level compared to that which existed in the Miocene before 5.3 million years ago when mean global temperature was about ~18.4°C, rising at a rate to which much of the fauna and flora can hardly adjust.

Nowadays as bombs keep falling, heads of governments jet around the world genuflecting to each other, signing arms deals, uttering honey words, while the corporate media discusses their official dinner menus, no solutions are reached for the worsening humanitarian crises nor the future on an uninhabitable Earth.

The myth of “net zero emissions by 2050”

by Andrew Glikson

It should raise people’s hopes to believe “net zero emissions by 2050” will arrest or at least slow-down global warming, had it not been yet another cruel hoax perpetrated in the wake of more than 50 years of obfuscation and denial of environment and climate science.

This is because:

For this reason, the essential reductions in emission must be accompanied with sequestration of atmospheric greenhouse gases by at least the amount of annual emissions.

The authorities are not listening to what climate science is indicating. Instead they are consulting with economists ignorant of the physics and chemistry of the atmosphere and of the consequences of global heating. An example is the absurd idea as if “a rise of 4°C in global average temperature would be “optimal” when the costs and benefits of mitigating climate change are balanced”.

Currently, CO2 concentrations in the atmosphere are increasing at the approximate rate of 2 to 3 parts per million per year. This leaves the fundamental question unanswered: What, if anything, would halt the fatal progression toward +4 degrees Celsius above pre-industrial temperatures, given that according to the IPCC (cited by the World Bank) a “four degree world would be one of unprecedented heatwaves, severe drought and major floods in many regions”. In perspective, global warming of the 20-21st centuries is at least 70 times faster than the rise of about 5 degrees Celsius over a period of about 7000 years since the last interglacial period. At this rate of environmental change mass extinctions are inevitable. When Professor Hans Joachim Schellnhuber (former climate adviser to the German Chancellor and the EU) was asked about the difference between a +2°C and a +4°C world, he replied: “Human civilization”.
