Measuring the Universe by Their Tiny Scale

Galileo:
from Kim Stanley Robinson's book Galileo's Dream*.

* This is a very good book, but I wish he had left out the subplot where 17th century Galileo is transported to the Jupiter system to solve(?) a controversy about the discovery of sentient life on Europa and in Jupiter. Galileo's tale is plot enough, and Robinson tells it well as historical fiction.

FWIW: Galileo was born three days before Michelangelo died. Newton was born later in the year Galileo died.

GISS Fits

GISS global anomaly, linear fit
versus quadratic fit:


Second-Warmest February

It's not getting much cooler: GISS and JMO both find February the 2nd-warmest Feb, after only 2016. The GISS global anomaly, 1.10°C is back above 1°C -- and tied for 4th among all anomalies-- and the land-only anomaly is 1.43°C, third highest of any month. (GISS's baseline is 1951-1980.) Another El Nino could be brutal.

Australians Say Six of Eight Models Suggest El Niño by July

The Australian Bureau of Meteorology says six of eight international models they consider suggest an El Niño by July.

(The Australians care because El Ninos typically bring below average winter-spring rainfall over eastern Australia.)

Needless to say, it'd be very interesting if this happens -- I can almost hear the shouting now.

AGW Predicted Before it Occurred

I like this, from Eric Steig of U Washington:

UAH v6.0 Finally Publishes Two Years Later

UAH has finally published their paper explaining the version 6 (here's the final submitted version), in the Asia-Pacific Journal of Atmospheric Sciences. This isn't exactly a prominent journal -- Roy Spencer claims, with no evidence offered, that it's all a conspiracy against them:
Our first choice would be an AMS or AGU journal, but they have one or more gatekeepers who inevitably get involved in the review of papers with “Spencer” or “Christy” as authors.

I might remind you of the Climategate email passage “Kevin [Trenberth] and I will keep them out somehow even if we have to redefine what the peer-review literature is!”

Trenberth also managed to get an editor to resign because Remote Sensing published one of my papers (which was never retracted though)…Trenberth apparently had some influence over that editor in the research realm.

Many of these journals are now tightly controlled to prop up the IPCC narrative.
I've asked him for evidence. I'm not holding my breath.

Recall that some people accused Karl et al of publishing in order to influence the 2015 Climate Conference. But their paper has been in peer review for about 1/2 year, and they published their paper at the same time as they introduced their new dataset. UAH did not, publishing their paper almost two years after making some huge changes to their data, far bigger than Karl et al's changes.

Just imagine the outcry if Karl et al has changed some regional monthly anomalies by over 1.4°C, as UAH did.


Winter Arctic Sea Ice Extent at Lowest Peak Yet

The maximum extents of winter sea ice in the Arctic are their lowest values yet, according to two different datasets, JAXA v2 and NOAA. (I think it's fair to call the peak now, several days after.)

JAXA v2 has Arctic SIE peaking on 3/6/17 at 13.878 Mkm2.

NOAA has Arctic SIE peaking on 3/5/17 at 14.447 Mkm2.

Don't ask me how these two datasets can differ by 569.000 km2. That seems like a lot, for a basic measurement (even by satellite). I don't understand it either.

But both are the lowest winter maximums in their records, going back to 1979. That counts for something.

The Movie "Geostorm" -- Just What We Don't Need

An apparently ridiculous, irrational look at geoengineering. In theatres October 20th.

Continental US Had Its 2nd-Warmest February

This February was the second-warmest in the continental US records (going back to 1895), after 1954.

That looks strange, 1954, but it was 0.25°F warmer then.

Still, this February's anomaly was 5.85°F above the 1980-2010 baseline, and 7.34°F above the 1901-2000 baseline. (Hey, it's NOAA who uses Fahrenheit; don't blame me.)

The 30-year trend is 0.47°F/decade. That's right, we're warming at almost half-degree every 10 years. It's 0.26°C/decade, or about 50% faster than the globe as a whole is warming. That's a pretty good rule for land warming versus global warming in the middle latitudes, and one I don't think the public is yet aware of.

So while the Paris Agreement tries to limit global warming to 2°C, that's 5.4°F in the continental US. And it's almost too late for the 2°C limit to hold, so USA48 could see at least 6°F of warming.

Except in the Pacific Northwest. Salem, Oregon was slightly below average last month, and we had 13.44 inches of rain in February, a record. That's 341 mm, if you must know.
