Our climate narrative set in stone
It is time for proper science journalism, time that our leaders, our TV media, and our press — along with the climate alarmists if they are game to come — to sit down with our earth scientists to learn the facts about climate.
The history of what climate has done since the Earth was formed is written in the rocks, the fossils and the ancient ice caps. It is there for all to read if they want to.
And what it says is that climate changes is driven by forces outside our control, such as solar flares. It always has and always will change.
Scotland was once a desert. There were glaciers around Kalgoorlie in WA and in the Sahara.
During what is known as the Medieval Warming era the Vikings were growing wheat in Greenland.
We have bounced from heat wave to ice age and back to heat wave since the world began, and it’s not going to change.
We have to stop talking about “carbon pollution”. Without carbon there would be no animal or plant life, as we know it at least, on Earth.
Coral reefs have survived many episodes of warm seas, as have many other biota.
When our coal seams were forming the air was thick with carbon dioxide, which boosted the growth of trees, ferns and other plant life.
As our populations grow we will need all the help we can get to feed them and carbon dioxide will play a part if we let it — such as turning the Sahara back into savannah.
Instead of fussing about global temperature we would do much better to focus on what we are doing to the environment with our wastes. Rob Ryan, Caravonica, Queensland (Our correspondent holds a MA (Geology) from Oxford University).
The IPCC sets before us the consequence of climate catastrophe if we continue with our heads in the sand.
But the good news is that the two Nobel Prize winners in economics were acknowledged for their negative and positive solutions concerning the problem.
The negative solution is that carbon pollution be taxed. The positive is that innovative research and development into solutions be funded.
That is, research on innovations to cut carbon emissions, boosting biological and industrial carbon capture and helping those adversely impacted by climate change.
Such innovations would be a massive boost to the economy, employment and education in science, technology and engineering.
Yes, it will require hard political decisions, as well as push back against vested interests, false science and the exit of politicians who lack the courage to lead and embrace science.

Discredited climate data
Once again we see the IPCC trotting out the same old scare tactics, using the same old, discredited data.
All one needs to remember is that during the Jurassic to Cretaceous ages, Earth was at its most fertile. Plants grew so quickly that the dinosaurs hardly needed to move around.
Global temperatures were somewhat higher than today, and CO2 was about 7000 ppm compared to 400 ppm today.
This resulted in very rapid growth of vegetation, which in turn led to the huge dinosaurs, and so on.
The great coal beds of the world were laid down in this time, some of them over 2000m thick. Just imagine how many trees would have to die to create 2000m of coal.
The most important point is that these very high levels of CO2 did not cause runaway warming of the planet. Carbon dioxide does not cause warming. It is a result of warming. Later, the temperatures dropped and the dinosaurs died out.
We would benefit hugely from CO2 at about 1700 ppm or a little higher.
Agricultural output would more than double, and most, if not all, of the deserts would green over, making for a much greener planet Earth.

Scepticism on climate
Climate scientists do not produce a marketable product, so cannot generate an income.
They must rely on funding to survive.
The more dire their predictions, and the more they can alarm the general public, the more chance they have of receiving future funding.
All reports from anyone relying on someone else to fund their activities should be read with a degree of scepticism. Don Wright, Leschenault
Big bucks coronary
Reading yesterday’s cover story on the Bux fraud, I can well understand one of the investors suffering a heart attack.
