In the great Permian extinction, about 250 million years ago, about 95% of ocean dwellers and 70% of land dwellers disappeared. Many species of fish, corals, reptiles, insects and plants were eliminated. This was just one of five mass extinctions and there have also been over twenty smaller ones. Dinosaurs, which once dominated life on earth, disappeared as did mammoths and woolly rhinos.

These were dramatic extinctions, but many species are disappearing quietly all the time – beaten by a changing environment, volcanism, meteor impacts, aggressive predators or competition for food and living space. Earth’s inhabitants and its climate are always changing. Even now, we live in an era of recurring ice ages where life ebbs and flows as the ice comes and goes.

Probably over 95% of all species that have ever lived on earth are now extinct. It should not be surprising that many species now on earth are headed for the exit door.

The natural world is not a still life, where even the most fragile and ill-adapted creature is guaranteed a permanent spot on the canvas. Earth’s biosphere is a moving picture and every era has its dominant actor. Other species spend varying times on the stage, and then most of them disappear. All species can be threatened by natural Earth changes.

Humans are part of the natural world, and have survived so far because they have adapted to changing environments by using brains, hands, tools and natural resources.

Preservationists think that the human species should exert herculean efforts to preserve every dying species. Attempting to preserve environments of the past, they lock up land, sea and mineral resources, prohibit development and oppose water conservation. And now, in a vain attempt to preserve the climate of the recent past, they are crippling our energy supplies with futile mandates and taxes designed to force-feed “green energy”.

They should be free to engage in preservation activities at their own cost with their own property, but should not use governments to force our whole society down this risky road.  

Our access to abundant, efficient, reliable energy is all that stands between us and widespread famine. If the “temperature pause” turns into global cooling, with less carbon dioxide plant food in the atmosphere, this danger will be multiplied.

We should not hasten our own demise with self-inflicted injuries.

Red tailed black cockatoos are threatened in my area. They only eat stringybark and buloke seeds. There are massive numbers of yellow tailed blacks. They eat pine seeds from the pine plantations and thrive on them. I like seeing the red tails but for goodness sake why can’t they eat the pine cones. If a species is so damned finicky about its food, why should we stress about it?

The global warming gravy train is running out of puff. I’m just looking forward to when all the big pushers of the scam, your Tim Flummerys, your Will Steffens, your David Karolys, Kevin Trenberths and the rest have to make their big humiliating climb-down. Trenberth said in 09: “The fact is we can’t explain the lack of warming and it’s a travesty that we can’t.” Back then the warming had stopped more than a decade previously, and the planet hasn’t warmed since. They’re looking more and more foolish! This is how it’s going to go: They will continue to look… Read more »

Put simply, nature experiments with species and develops where possible. Sometimes some of these fail, or their usefulness in nature expires.

Off topic . I wonder if there is actually any proof that oil and gas are fossil fuels. Coal I know is. Coal is relatively shallow. But oil and gas can be 6 k deep. To call this fossil fuel becomes implausible . Considering planets like Neptune are made of methane and some moons have lakes of liquid methane, then perhaps when the earth was formed it somehow trapped a layer of methane. Or coincidently 6k is the same depth as our deepest oceans. Perhaps the incredible pressures at that depth are able to trap carbon in the form of… Read more »

Global warming/Climate change, call it what you like,it’s kinda like religion and the belief (or not) of a greater power isn’t it? You either do or you don’t! You simply cannot dislodge someone from their view, they have their catchcry “The science is in!”,is the modern day equivalent of “It’s in the bible” I’ve never seen nor read any of the science that is “in”. I’m not sure on where to find these pearls of wisdom, as for the bible, it resides in the “Fiction” section of most libraries and as such convinces me of nothing. 60 years of reading… Read more »

We won’t have loads of uranium for much longer, Mr Rabbott is selling it of to India. As far as food goes, there is always China. They supply at least half our food already.

Did I read that the BOM has been fiddling the figures re temperatures in Australia over the 20th century, particularly the first half? Funny, the massaged figures support global warming, when if the were left alone, no such support.

DJT, what’s your obsession with electricity, I use very little, heat and cook with wood readily available, water I store in tanks, electricity if I need it start the generator, and staying at home for 5 days no problem we do that now, nearest shop is 23 klm away. kangaroo tastes good to, thousands of them round here.

We are all suffering from a fatal disease, it’s called living. For what it’s worth I think all individuals should be able to go home close the door and survive for 5 days. Turn the electric off and the water from the main, no going to the shops. Would you survive? There are several scenarios, local township, no problem, State, 5 days, Solar flare half the earth, deep shit, 2 years.

This is where true science resides, comfortably, and you Mr Forbes report it as it is. The bandits on the other side, alarmists, greenies, do and feel gooders have misrepresented, trashed and tortured science for their own twisted ideological fantasies of utopian ideals taking a gullible public in their wake, sadly infiltrated mainstream politics with costly decision inflicting pain for no gain. Keep them coming, Viv. Extinction happened during the Great Flood of Noah, hence mass continental burial of dinosaurs and all living, if I may add.

All well and good to say extinction is natural but we certainly don’t help. All our farmland was once forest. Greens go on about CO2 but say nothing of the real cause I think that is just what I said. We’re destroying forest. The great CO2 sink

so………. we shan`t be needing U beaut new flash airports, Towers of high rises.. better freeways, agriculture plans.. petrochemical pipelines etc .. no need for infrastructure if it`s all going to be blown sky high or fully toxified.. hmm? is that their plan too? Sheesh.. so why are we paying for it all then, we may well ask?(wink) Wow no need to pay all those extreme billions of debt back after all?Is that it?

On the one hand they are insisting we pay rates, levies, huge odd* elect bills? for less usage, and infrastructure plans on guestimated well into the future calculation excuses.. for the influx and ten yrs in advance (um) plan.. the so called need..yet on the other they are trying to cancel out incentive and insist we are all doomed.. ?? So I don`t think they know what they want frankly.

We, the majority, (I think) do not believe the inane predictions of climate catastrophe imbiciles. But we allow it to happen and impact adversely on our lives. It is us, the weak, no action observers who are the most culpable… Not the imbiciles…

Good point , and all those Swiss bank accts in vain.. no politicians wages or purpose in any productivity ..no point in edu ?? or families ?? no point in caring? and yet they insist too there is a dire pop explosion too .. so which one is it.. longevity as they insist(due to expert health researchers?) or doom to suit a strange mind set `agenda`.. I`d say nature will decide humanity`s cycles as it always has.

Mr. Forbes, in a letter to Menzies House in 2013 you said “Politicians persevere in their energy stupidities even though the science and the evidence no longer support them”. I’m sure that many of your readers would appreciate a detailed report of how the science is flawed, with verifiable data and references. I know that your mandate is to focus on “… putting all aspects of the climate stupidity into short simple articles …” and to ” …change public opinion from the bottom up”. By why treat us that way? Most of us here are older and wiser and do… Read more »

Smile sent to you and your family Viv*. I agree with your rationale, here.I read recently re; a plant, that was on the C End.. list.Dwelling on the info presented, one would be more interested to problem solve the `reason` so as to confirm the info, rather than, being unrealistic re it`s procreation difficulty.It is the learning aspect one finds intriguing..more so than the…sentimentality imo.Thank-you Viv for your mature & practical, yet pragmatical views.

It is amazing the nonsense some authorities engage. For instance, little penguins are being thinned out by an increasing number of fur seals in Kangaroo Island. One solution? Desex the male seals. Meanwhile 100 kms East, at Victor harbour, authorities are preventing the colony of little penguins from breeding because the colony does have enough room for a large colony. Go figure?
