Your car causes war! Feel the fear about Australia’s climate security.

Not only climate change destroy coffee, chocolate and beer, but war is going to ruin your weekends too.

When war breaks out and they come for your first-born, you may ask if you should’ve left the car in the garage more. You may wonder if you could have used public transport, and converted all the lights to LEDs sooner and only eaten locally sourced oranges. Feel the guilt. Send them your money.

Walk for Peace!

There is no end to the combinations and permutations of ways to use fear to ask for funds. Before we set up Departments of Climate Change, Global carbon trading markets, Emissions reductions schemes, and prepare our Defence Force for the wave of violent desperate climate refugees that were forecast but didn’t come, we need one thing more than any other. We need climate models that actually work.

“Climate change will destabilise our region and undermine our way of life, yet we are doing nothing to prevent it.”

Exactly, we are doing nothing, nothing useful at all. Though we are pouring billions of dollars down deep wells trying to reduce CO2, and prepare for a climate we absolutely cannot predict. (Is that the kind [...]

Climate Change will ruin beer, chocolate, coffee, says The Guardian

More adventures in science from The Guardian. “No more beer, chocolate or coffee: how climate change could ruin your weekend”.

Obviously, since coffee, hops, and cocoa are all plants which like arctic weather and frosts, and grow mainly in Greenland glaciers, a warmer world will devastate these essential foods. I’m in tears just thinking about it.

Likewise, being alien silicon lifeforms, these plants will struggle as the pollution called carbon dioxide rises from 0.04% of the atmosphere to 0.05%. Oh the pain. If only these plants used CO2 as a basic building block like every other plant on Earth.

It must be tough being so much smarter than the rest of the world.

….

Somehow, somewhere, The Guardian become The Guard-Onion. I just can’t take these people seriously anymore. Dear Karl Matheisen, what were you thinking?

 No more beer, chocolate or coffee: how climate change could ruin your weekend

Karl Mathiesen

Climate change is the biggest threat to all of civilisation our species has faced since the 80s. Scientists say rising seas will envelope major cities around the world while heatwaves will bring wildfires and torrential rains bring floods. And the global economy is stuffed.

Climate Change could make humans extinct says “expert”

Time to panic. Climate Change could make humans extinct, warns the Sydney Morning Herald.

“The Earth is warming so rapidly that unless humans can arrest the trend, we risk becoming ”extinct” as a species, a leading Australian health academic has warned.” The trend, the trend, which trend exactly? The trends have been flat on the surface for 17 years, so if that trend continues, we risk “staying the same”? That’ll be deadly. In 1997 global population was 5.8 billion. Since then, there has been no significant warming in the part of the world that humans live in, and global population plunged to 7.2 billion.  Hold off on the End-of-Humanity Party.

Helen Berry, associate dean in the faculty of health at the University of Canberra, said while the Earth has been warmer and colder at different points in the planet’s history, the rate of change has never been as fast as it is today.”

Luckily Helen Berry has seen the Neanderthal global data sets from the paleolithic era which recorded those climate changes. Otherwise how would she know the exact rate of global warming from, say, 11,900 -11,860BC or 42,040 – 42,000BC? The only records I’ve seen (like, the ice [...]
