Alan Kohler (ABC economics guru) thinks there is so much overwhelming evidence that a Royal Commission would persuade the skeptics. Skeptics say, yes please, lets do the due diligence that’s never been done. Go on convince us.

Over 50% of Australians are skeptical of the IPCC explanations (think that’s changed? See the last election results). Over 60% don’t want to pay even $10 a month. So lay it out. We want a Royal Commission, some kind of public debate, based on scientific evidence, not “scientific opinion”. It’s not enough to show the climate’s changed, we expect to see evidence about cause and effect. Let’s get all the uncertainties laid bare, not buried behind models and hidden by indignant namecalling. What are they afraid of?

If you worry, like I do — that any institutionalized forum can be another waste of money — captured by the swamp — then view this as a play in the only court that matters, the court of public opinion. Let Alan Kohler know there are lots of skeptics and we want a debate. Ask why the ABC won’t tell the world that there are tens of thousands of scientists and engineers, including NASA stars, […]

Life on Earth mostly made it through 500 million years of asteroids and supervolcanoes only to be wiped out by a half a degree temperature rise. This really will be unprecedented.

Climate change could destroy half of Earth’s animal and plant species in the next 50 years, disturbing study says

Despite animals surviving temperature rises of 20 degrees every day, a half a degree of warming in 50 years will kill off half the species on Earth.

A disturbing new study suggests that climate change could wipe out half of the planet’s animal and plant species by 2070.

The research notes that if temperatures rise 0.5 degrees Celsius around the globe, approximately half of the world’s species would become locally extinct. If temperatures were to rise 2.9 degrees Celsius, 95 percent of the species would become locally extinct.

Note the scale on the graph of the last 500 million years. I marked half a degree in the red box.

I’m not too concerned about life on Earth surviving the next 50 years. But at this rate of decay, science is cactus.

These researchers think Earth is a […]

Pick a number, any number — the message is always the same. In 2018 the IPCC dropped the arbitrary 2C target to an arbitrary 1.5C target. The world hadn’t warmed fast enough, and worse, the new round of CMIP6 models were pushing their estimates of climate sensitivity up. But regardless, there are PR points to be made in every change. It’s an excuse for another round of “worse than we thought” press releases.

Commenter Joe teased:

Have the IPCC now become deniers? looks like we can only expect only .5 degrees C warming over the coming decades….

You’ve lost sight of the pea.

All the wild predictions are based on “Post Industrial” there has been about 0.95 deg since then, plus 0.5C brings us to the magic 1.5.

What you have to see is that all the $billions is about “preventing” an imperceptible and completely harmless 0.5 deg C change in temperature that might just come naturally anyway.

You are being duped. The aim frankly is to create an income stream via treaty that requires sovereign countries to levy […]

Looks like the dams will still fill. Sydney’s main dam — the Waragamba was only 42% full a few days ago, now it’s 70% full, and most of the fires are out, or will be soon. 16 river systems have flooded, and 13,000 people are being evacuated. Where is that hotter-drier future when you need it?

Sydney rains: Record rainfall brings flooding but puts out mega-blaze

Sydney has been hit by its heaviest rain in 30 years, bringing widespread flooding but also putting out two massive bushfires in New South Wales. Australia’s weather agency said 391.6mm of rain had fallen in the past four days in Sydney, more than three times the average rainfall for February. About 100,000 homes are without power, and officials have warned flash floods could be life-threatening.

Jan 2nd 2020: “February to April has roughly equal chances of being wetter or drier than average for most of Australia.
