Wobbly apocalypse — Humans to blame for making days longer, throwing planet off balance

By Jo Nova

Is there nothing fossil fuels can’t do?

Climate change makes the Earth wobble on its axis. Now, if you shower too long, and enjoy that beefsteak too much, you could affect the tilt Earths axis. Are you feeling guilty yet, or just fed up that modern science is indistinguishable from the prophesies of Neolithic shamen?

Earth is wobbling and days are getting longer — and humans are to blame

By Harry Baker

New studies, which utilized AI to monitor the effects of climate change on Earth’s spin, have shown that our days are getting increasingly longer and that our planet will get more wobbly in the future. These changes could have major implications for humanity’s future.

We’re talking of fractions of a millisecond:

Initially, these changes will be imperceptible to us, but they could have serious knock-on effects, including forcing us to introduce negative leap seconds, interfering with space travel and altering our planet’s inner core, researchers warn.

So it’s probably your air-conditioner in Power Mode, but it could be due to crustal plates shifting:

A day on Earth lasts about 86,400 seconds. But the exact time it takes […]

Another day in Climate mythology: coal fired plants are slowing Earths rotation

By Jo Nova

Sometime a few years ago the Carbonistas stopped trying to pretend it was science, climate change has morphed into a ecclesiastical piñata instead. (If they whack it hard enough, grants fall out).

Instead of talking about 30 year trends (because they were wrong), the experts started coloring weather maps blood red and hyperventilating with every warm weekend. So it makes perfect sense they need the ritual reminders of holy mythology, and this is one of those stories. It’s the weekly nod for the awestruck fanatics that the world really does revolve around “climate change”. They can nod solemnly, and pat each others solar panels.

The theory is that because our showers are too long or our beef steaks are too big (don’t you feel important?), the poles are melting and some ice near the poles has dribbled out to the equator, slowing the planet’s spin. Since the Earth is a rotating ball of rock 10,000 kilometers across, the movements of a few millimeters of water on the surface are somewhat minor. But nevermind. So the dire news, such as it isn’t, is that the Earth’s clocks might have to be wound back by one whole second in […]

The SOI still rules

Who would have thought that if you knew the air pressure in Darwin and Tahiti in June, you could figure out that the start of 2011 might be a Stalingrad Winter up North and a cooler wetter summer down south (Not that people in Sydney feel all that cool right now). But the air pressure ratios are reported as the SOI (Southern Oscillation Index) and it’s the handiest thing if you like predicting global temperatures 7 months ahead. Look at that correlation.

Since June last year Bryan Leyland has been using the simple connection described by Carter, De Freitas, and McLean in 2009 to predict up and coming temperatures.

So far, for what it’s worth, he’s right on track.

Such is the power of the stored pool of cold that is the bottom three-quarters of the Pacific Ocean. And when you look at how vast the Southern Pacific ocean is, is it any wonder it has such an influence? All that heat capacity…
