August 2022 Greenhouse Gas Report

No evidence here that humans have done anything yet to stop and reverse GHG emissions to get us off the road to Hothouse Earth and global mass extinction.

As the ocean ice around Antarctic approaches its maximum spread for the year, on 19 August 2022 Antarctic sea-ice extent is the second lowest ever as recorded in the satellite era as recorded by the US National Snow & Ice Data Center. As sunlight again begins to shine on the antarctic polar region more of the ocean surface is exposed to solar heating that will warm the waters surrounding the ice cap to speed glacial melting and slow the formation of more sea-ice next winter.

July’s trends in global warming continue in August. Heatwaves, fires, and droughts in the Northern Hemisphere continue, e.g:

In the run-up to Australia’s May 22 Federal Election many articles on our Climate Sentinel News documented the reality, mechanisms and dangers humans face if global warming is allowed to continue. If global warming runs away due to already documented feedback mechanisms heating will continue at an accelerating rate that will soon rise beyond the capacity anything humans can do to stop it.

Critical time is wasting. It is time for all of our politicians, new and old to lead our country in massive mobilization to stop carbon emissions and start implementing carbon capture and sequestration processes able to extract excess amounts from the atmosphere. Biological processes are likely to scale up a lot more successfully than engineering solutions. Geoengineering to increase Earth’s reflectivity (i.e., albedo reduction) may also help. We know how to stop emissions, but sequestration and albedo reduction will require significant research that needs to start now.

TIME IS OF THE ESSENCE, AND THE URGENCY GROWS WITH EVERY DAY OF DELAY!

Some call me a 'climate scientist'. I'm not. What I am is an 'Earth systems generalist'. Born in 1939, I grew up with passionate interests in both science and engineering. I learned to read from my father's university textbooks in geology and paleontology, and dreamed of building nuclear powered starships. Living on a yacht in Southern California I grew up surrounded by (and often immersed in) marine and estuarine ecosystems while my father worked in the aerospace engineering industry. After studying university physics for three years, dyslexia with numbers convinced me to change my focus to biology. I completed university as an evolutionary biologist (PhD Harvard, 1973). My principal research project involved understanding how species' genetic systems regulated the evolution and speciation of North America's largest and most widespread lizard genus. Then for several years as an academic biologist I taught a range of university subjects as diverse as systematics, biogeography, cytogenetics, comparative anatomy and marine biology. In Australia, from 1980, I was involved in various activities around the emerging and rapidly evolving microcomputing technologies culminating in 2 years involvement in the computerization of the emerging Bank of Melbourne. In 1990 I joined a startup engineering company that had just won the contract to build a new generation of 10 frigates for Australia and New Zealand. In 2007 I retired from the head office of Tenix Defence, then Australia's largest defence engineering contractor, after a 17½ year career as a documentation and knowledge management systems analyst and designer. At Tenix I reported to the R&D manager under the GM Engineering, and worked closely with support and systems engineers on the ANZAC Ship Project to solve documentation and engineering change management issues that risked the project 100s of millions of dollars in cost and years of schedule overruns. All 10 ships had been delivered on time, on budget to happy customers against the fixed-price and fixed schedule contract. Before, during, and after these two main gigs I also did a lot of other things that contribute to my general understanding of complex dynamical systems involving multiple components with non-linear and sometimes chaotically interacting components; e.g., 'Earth systems'. Earth's Climate System is the global heat engine driven by the transport and conversions of energy between the incoming solar radiation striking the planet, and the infrared radiation of heat away from the planet to the cold dark universe. As Climate Sentinel News Editor, my task is to identify and understand quirks and problems in the operation of this complex heat engine that threaten human existence, and explain to our readers how they can help to solve some of the critical issues that are threatening their own existence.
