Well the data set in question (ERSST) is an anomaly product, not an absolute product. Here, Zeke Hausfather explains they buoys issue really well: https://andthentheresphysics.w...

The baseline is indeed the average temperature for a pre-defined interval. However, it is the average for the dataset being considered. In other words, you produce the baseline average after you’ve done the adjustment. The anomalies are then relative to that baseline. Therefore, it doesn’t matter if you shift the buoys up to the ships, or the ships down to the buoys. Once you’ve done the shift, you then calculate the average for the pre-defined interval and present your data as anomalies relative to that baseline.

Do you understand what an "anomaly product" is? If you apply a consistent adjustment across the whole series, the mean temperature changes to match across the whole series so the anomaly from the mean, and the trend of that anomaly, is the same regardless of the direction of the adjustment. So your claim that this biases the anomaly higher is false, which is confirmed by the HadSST3 test run and the buoy-only series I linked to earlier.

The direction of the adjustment makes no difference to the trend (this has been tested by running it both ways) and the new NOAA series puts 7x more weight on the Argo buoy data where available. It's been further tested by constructing an unadjusted buoy-only record which shows the same trend (see https://skepticalscience.com/b...).

Comment Re:Total Capacity (Score 4, Interesting) 192

They're playing some tricks with the numbers to get capacity factors close to 0.3, which is physically impossible unless all your PV panels are super-high efficiency and track the sun. But this isn't the sort of thing you can just cover up. It's trivial to calculate the actual capacity factor for PV solar:

  • Installed peak capacity at the end of 2014 and 2015 was 18,173 MW and 25,459 MW respectively. So figure average capacity for 2015 was (25459 + 18173)/2 = 21,816 MW.
  • PV solar generation for 2015 was 23,232 GWh.
  • There are 8766 hours in a year (factoring in leap years).
  • (23232 GWh) / (21.816 GW * 8766 hours) = 0.121 capacity factor.

Yeah sure, there's a conspiracy to cover up the real numbers. Or, you know, you might have botched your calculations. You took the solar output from large utilities only and divided it by the total solar capacity including distributed generation.

Solar capacity factors of >25% are relatively easy in the sun belt and can go as high as 36% with tracking and a high panel-to-inverter ratio (Lawrence Berkely study, 2014 figures).

Comment GadgetBridge will keep Pebbles going (Score 1) 193

There's an open source app called GadgetBridge that will support all the basics for Pebbles, and will keep working even if the Pebble cloud dies. You will still be able to load new apps and watchfaces and re-flash firmware. Apps that need to access the Internet may not work (for now, devs can contribute). As a side-bonus you get greatly increased privacy.

This is Android only, I don't know if there's an iOS equivalent (anyone?).

Submission + - ESA: European Mars Lander Crash Caused By 1-Second Glitch (space.com)

An anonymous reader writes: The European Space Agency (ESA) on Nov. 23 said its Schiaparelli lander’s crash landing on Mars on Oct. 19 followed an unexplained saturation of its inertial measurement unit (IMU), which delivered bad data to the lander’s computer and forced a premature release of its parachute. Polluted by the IMU data, the lander’s computer apparently thought it had either already landed or was just about to land. The parachute system was released, the braking thrusters were fired only briefly and the on-ground systems were activated. Instead of being on the ground, Schiaparelli was still 2.3 miles (3.7 kilometers) above the Mars surface. It crashed, but not before delivering what ESA officials say is a wealth of data on entry into the Mars atmosphere, the functioning and release of the heat shield and the deployment of the parachute — all of which went according to plan. In its Nov. 23 statement, ESA said the saturation reading from Schiaparelli’s inertial measurement unit lasted only a second but was enough to play havoc with the navigation system. ESA said the sequence of events "has been clearly reproduced in computer simulations of the control system’s response to the erroneous information." ESA’s director of human spaceflight and robotic exploration, David Parker, said in a statement that ExoMars teams are still sifting through the voluminous data harvest from the Schiaparelli mission, and that an external, independent board of inquiry, now being created, would release a final report in early 2017.

Submission + - NASA's Climate Research Is Set To Be Scrapped (theguardian.com)

dryriver writes: The Guardian reports: Donald Trump is poised to eliminate all climate change research conducted by Nasa as part of a crackdown on “politicized science”, his senior adviser on issues relating to the space agency has said. Nasa’s Earth science division is set to be stripped of funding in favor of exploration of deep space, with the president-elect having set a goal during the campaign to explore the entire solar system by the end of the century. This would mean the elimination of Nasa’s world-renowned research into temperature, ice, clouds and other climate phenomena. Kevin Trenberth, senior scientist at the National Center for Atmospheric Research, said as Nasa provides the scientific community with new instruments and techniques, the elimination of Earth sciences would be “a major setback if not devastating”.“It could put us back into the ‘dark ages’ of almost the pre-satellite era,” he said. “It would be extremely short sighted".
