CO2 Data Reveals Current CO2 Starvation


Two great sequestration periods occurred since the mid-Paleozoic and both appear to coincide with evolution of plants. The first woody plants and trees arose in the Middle Devonian and fueled the large coal swamps of the Carboniferous Period. Later explosion of the flowering plants (angiosperms) occurred in the Cretaceous. All the while additional C was being locked up in limestones. Also in high TOC (Total Organic Carbon) muds that were converted to the shale/mudrocks that we are now liberating with fracking.

Carbon Dioxide and the Oceans – temperature controls carbon dioxide, not the reverse.

71% of the earth’s surface is covered by water and large areas of the land are covered by frozen water. Water and water vapour are also significant components of the atmosphere.

The atmosphere and its trace component of carbon dioxide is a very thin skin in close contact with the surface of all of this water. Carbon dioxide is very soluble in water and Henry’s Law says that as the temperature of water changes the quantity of carbon dioxide dissolved in that water will change.

Thus if the sea surface temperature increases, carbon dioxide will be expelled to the atmosphere just like carbon dioxide bubbles are expelled from a warming beer. And as sea surface temperature falls, carbon dioxide will dissolve in the cooling water and this reduces the carbon dioxide in the atmosphere.

GREENS LAUNCH ATTACK ON… Trucks?

Electric vehicles might be okay for suburb hopping in big cities, but I doubt there is a farm in Australia that would be able to run without any petrol or diesel. The Greens’ calls to ‘rapidly transition to electric vehicles‘ for their net zero economy by 2035 shows they have no clue of the energy requirements in transport, industry and agriculture.

Three Costly Aussie Wars – Climate, Covid and China

By Viv Forbes

Australian politicians are trying to maintain their never-ending Climate War on carbon fuels while waging a Lockdown War on the elusive Covid virus and also provoking a Trade War with China, our biggest trading partner.

We cannot afford three hopeless and costly wars at once. One would be too many. Continue reading “Three Costly Aussie Wars – Climate, Covid and China”

Are We Really in a New Climate Era?

By Howard Thomas Brady

The Federal Gallery journal has published this article by Dr Brady in its March 2020 edition. Dr Brady says that “politicians on both sides of the climate debate are making statements that are actually false. In good faith they think that certain propositions are correct”, so he needs to show otherwise.

Howard Thomas Brady has written the book Mirrors and Mazes: a guide through the climate debate (2016). He has post-graduate degrees in Philosophy, Theology and Antarctic science. He also has a climate website listing various talks and YouTube presentations: http://www.mirrorsandmazes.com.au.

Time for Climate Sense

By Viv Forbes
23 December 2019

Svante Arrhenius (1859-1927) was a Swedish scientist who first claimed that the burning of hydro-carbons like coal, oil, gas, peat and wood may cause global warming.

In 1895 he calculated (incorrectly) that a doubling of the atmospheric CO2 concentration would lead to a 4-5o C rise in global temperature.

However, Arrhenius suggested that this increase could be beneficial, making the various climates on Earth “more equable” and stimulating plant growth and food production. Continue reading “Time for Climate Sense”

HUMAN-INDUCED CLIMATE CHANGE – A Geoscientist’s View

Consultant geologist Dr Geoff Derrick was invited to present this talk to a conference held in Brisbane at the Pullman Hotel, 22-23 July 2019. The conference was organised and hosted by DANA, a New Zealand-based group of Forest Industry Advisors. The conference was titled “Innovations in the Australian Forest Industry Sector”, and featured 2 days of lectures and workshop discussion, followed by a half-day field trip to Woodchip export facilities at the Port of Brisbane.

Trees, Fires, Climate and Carbon Dioxide

By Jim Steele. Published in Pacifica. Tribune August 20, 2019

There are too many fear mongering politicians pushing an “existential climate crisis”. I find the climate history told by the trees far more trustworthy, and the trees are whispering there is no crisis.

This summer I taught a class on the Natural History of the Sierra Nevada for San Francisco State University’s Sierra Nevada Field Campus. The first day we taught students how to identify the trees. Once students know their trees, they can easily see how tree species vary with elevation, temperature, moisture, and snow pack. They can see which species colonize open sunny areas and which trees need shade before they can invade. Old time naturalists used trees to identify “life-zones” where different species of mammals, birds, insects and other plants can be found. Furthermore, when you listen to the trees, you can see change.

The class explored forests along the North Yuba River. Free from politics, trees tell us about changes in fire frequency, logging, climate change and ecosystem resilience. Photographs taken during the late 1800s during California’s gold rush days, revealed the total devastation of local forests. Gold miners needed wood for heating and cooking, for their metal forges, and for timbers to reinforce their mines. They needed wood to build flume boxes that altered river courses to expose riverbeds. Flume boxes also carried water from high to low elevations where giant water cannons completely washed away hillsides in their search for gold.
