Australia: 2019 was not the hottest summer say satellites — it was just as hot in 1991

All that global warming and nothing to show for it?

Headlines rang out telling Australians that last summer was the hottest ever. But, according to the UAH satellite series, the hottest — just barely — was in 1991, when CO2 was a wonderful, safe 356 ppm. Since then, humans have emitted more than half — fully 58% — of all the emissions we have ever emitted since we crawled out of those dank caves. CO2 levels are almost 50 ppm higher now, and temperatures are almost as high.*

Wonder if this summer will get close to the summer of 1991 (and we wonder if Victoria will keep the lights on).

The UAH data comes from NASA satellites, which cover all the Australian land mass every day and night.

The BOM (and NASA) prefers to use Australian ground data which is based on sparse thermometers that keep changing sites and equipment, are located near airport tarmacs, buildings, and cars. When readings are too cold, the BOM sometimes deletes them. Temperatures from thermometers hundreds of kilometers apart are magically homogenized and “corrected” through a secret computer process and two thirds of our warming comes from those adjustments, not from CO2 [...]

ABC Climate Zombie Myths and Fantasy Strawmen. Who’s feeding the trolls?

Skeptics are now the brain-eating undead from Haitian Cult Voodoo. Just more namecalling in lieu of science. The ABC has become the US Weekly,  TVWeek, or OK! of national policy, filled with inane clickbait animations, fictional stories and fantasy myths.

Looks like it’s projection again

Here’s a guy who believes that we control storms, floods and droughts with solar panels and wind turbines. The only climate zombie that needs hosing down is all his. He’s the one saying that the type of milk you drink, or your funeral service are to blame for random stuff like spotted quoll fertility, shark attacks, or tornadoes. Go vegan to save the planet!

Poor Nick Kilvert is so badly trained he can’t figure out why ideas like “CO2 feeds plants” just won’t die. The mystery of how the truth keeps coming back (despite their best efforts). So this weekend he put out a handy condescending guide of strawmen and mythical myths for beleaguered believers who are lost for answers to skeptical scientists. The man’s cult-like belief is so obvious, the real question we need to ask our elected MP’s is why are we funding an journalistic organization which has staff who are so incompetent, [...]

BOM homogenization errors are so big they can be seen from space

It’s just not cricket. And in so many ways.

Shame to let a perfectly good dataset go to waste… Australian data comes from some of the longest stations running in the Southern Hemisphere; it could be useful. Instead we get more evidence here that the BOM’s magical and secret homogenization adjustments can take poor data and spread false signals into better data. Homogenisation errors are already visible in a site-by-site analysis, but this shows the problems may be so big they affect averages across the whole of Australia, and we can detect them with satellites.

Tom Quirk continues comparing the satellite record of Australia with the BOM surface version. Previously, he (and for the record, Ken Stewart in 2015) showed that some discrepancies are due to the effect of heavy rain or drought. But now he looks further and finds that not-so-coincidentally, the largest gaps and most “inexplicable” differences occur in the mid nineteen-nineties, the same years the BoM shifted from using old large Stevenson screens to electronic thermometers. Around the same time, the large screens were often also swapped for much smaller ones too — like double jeopardy for data. Oddly, spookily, the BOM makes many adjustments to data [...]

Monckton: IPCC climate models speeding out of control compared to real world

Christopher Monckton reminds us of just how badly the “experts” have failed in the last 15 years, even including the recent hottest ever El Nino months. China bombed the atmosphere with record carbon “pollution” — worse than we thought. The world though, warms sedately at a mere half a degree per century. This is what 95% certainty looks like.   — Jo

Introducing the global warming speedometer

A single devastating graph shows climate panic was unfounded

A single devastating graph – the new global warming speedometer – shows just how badly the model-based predictions made by the Intergovernmental Panel on Climate Change have failed.

Hottest seasonally adjusted month EVER! Hyperbole runs wild.

Who needs a trend when you can have a hot month?

The news is all over the media — Feb 2016 was a record hottest ever month — and the Global Worriers  are saying “Meltdown“, “Planetary Crisis” and “Terrifying Milestone.”

But the Pause is still there. No matter what happens now, the world didn’t warm for 18 years, and that shows the models can’t predict a thing. (Unless they take solar factors into account, which they don’t).

One big El Nino didn’t fix the climate models now. (They can’t predict El Nino’s either).

Nothing that happens after 2015 can change the amount of energy that went missing during the Pause that no mainstream modeler predicted. Remember these models are supposed to be coupled ocean and atmosphere models, but none of them understand what causes shifts in the PDO, or many other natural cycles and currents of the ocean. So with every natural spike up, modelers unscientifically leap in glee, and with the other 99% of the data, they blame internal variability. But a real scientist is scientific every month. Trends, guys, trends. That’s what this debate was supposed to be about. Not spikes. Not noise.

During the last whopper El [...]

Australia’s record hottest 12 month period? Not so say the Satellites

Another round of government-funded PR went out a couple of weeks ago, across the obedient Pravda-media. It told us about another meaningless “record” that was probably not a record, and wouldn’t tell us whether man-made warming was the cause, even if it was. Not a single journalist had the wherewithal, nous or intellectual honesty to search the Internet looking for a different point of view. Though, in their defense, how could they have guessed that Prof David Karoly wouldn’t know about the UAH satellite program to measure temperatures? (It has only been running since 1979.)

This below, are the 12 month averages over Australia by satellite. Graphed at Kens Kingdom by Ken Stewart, with no doctorate in climatology and no government funds.

In the troposphere over Australia it was a hot year but not a record.

 

For the third time this year we’ve been hit with claims of a “hottest ever” record that doesn’t tell us anything about the climate, but does reveal a lot about the sick state of government funded science, corrupted, decrepit, and so far from being scientific it might as well be run by Greenpeace.  If the government stopped funding climate science entirely, climate [...]

Has the world started cooling? Hints from 4 of 5 global temperature sets…

I’m not keen on short term trends at all, they have a habit of flicking in and out of statistical significance with each month’s new data, or even switching from cooling to warming. But for what it’s worth, and only time will tell, perhaps the world entered the downswing of the PDO cycle in temperatures circa 2005.

If the world was entering a gently cooling phase, this is what it would look like

Syun Akasofu pointed out that there was a simple 60 year oscillation of global temperatures (about 30 years of warming, about 30 years of mild cooling) on top of a long slow rise that started more than 200 years ago. He predicted that we were at the top of one of the cycles, and were about to see the beginning of a cooler cycle. This early data suggests he may be right.

See the little red dot with the green arrow at about the 2010 mark. Dr Syun Akasofu

The cooling for the last eight years is statistically significant in 4 of the 5 major air temperature datasets. One, UAH, shows a small (statistically insignificant) rise since 2005.

And here’s the political point: how many of [...]
