The key requirement for the method of science is scepticism.
The scientific method is to make falsifiable hypotheses and then to check the hypothesis by gathering the evidence to check the falsifiability.
The IPCC and the Global Warming Orthodoxy have been making alarmist predictions for the last 20 years and their hypothesis comes in three parts:
- That global warming is occurring and will continue for at least the next 100 years
- That human activities are the primary cause of the global warming being observed, and
- That man-made emission of carbon-dioxide is the most significant human activity driving climate change.
In the last 20+ years, comparing actual observations show that each one of these 3 parts of this global warming hypothesis is – at best – oversimplified and – at worst – just plain wrong. “Wrong” in the sense that the causality proposed does not exist and that the mechanisms proposed for the causality are incorrect or non-existent. The IPCC predictions are being proved wrong and it is time to ditch the hypothesis.
IPCC predictions falsify global warming hypothesis
The 27th January article in the Wall Street Journal “No Need to Panic about Global Warming” by a number of scientists displaying true scientific scepticism was immediately criticised by members of the Orthodoxy. The original authors now reply to these criticisms in the WSJ:

(Reuters) – Unreported data from early trials of experimental medicines in humans can result in harm to future patients and needless costs for health systems, according to scientists writing in the British Medical Journal on Wednesday.
The role of statistics in research leads to obvious risks for the drawing of conclusions about causal relationships between parameters without actually increasing the understanding about the underlying mechanisms. In pharmaceutical and health research such conclusions provide enormous financial benefits for the researchers and their sponsors – and not always in the interests of the patients involved.

Breaking!
On Tuesday, 22 November at 20:25 UT, ESA’s tracking station at Perth, Australia, established contact with Russia’s Phobos-Grunt spacecraft. This was the first signal received on Earth since the Mars mission was launched on 8 November. ESA teams are working closely with engineers in Russia to determine how best to maintain communications with the spacecraft.

OPERA is one set of experiments at CERN’s Italian partner labs at Gran Sasso and ICARUS is another.
In September Opera reported the FTL neutrinos to widespread scepticism, wonder and some delight. Last Friday the OPERA scientists reported that new experiments supported the September results.
But on Saturday the ICARUS scientists reported – also on the same website- that they had analysed the September results and that they do not stand up!!!
A search for the analogue to Cherenkov radiation by high energy neutrinos at superluminal speeds in ICARUS
Reuters reports:
An international team of scientists in Italy studying the same neutrino particles colleagues say appear to have travelled faster than light rejected the startling finding this weekend, saying their tests had shown it must be wrong.

The CERN results in September indicating faster than light neutrinos have stood up to one set of tests to check the result.
Reuters:
The new experiment at the Gran Sasso laboratory, using a neutrino beam from CERN in Switzerland, 720 km (450 miles) away, was held to check findings in September by a team of scientists which were greeted with some skepticism. Scientists at the Italian Institute for Nuclear Physics (INFN) said in a statement on Friday that their new tests aimed to exclude one potential systematic effect that may have affected the original measurement. ….

Phobos-Grunt is still circling Earth at an altitude between 128 miles and 210 miles after launching Tuesday from the Baikonur Cosmodrome in Kazakhstan for Mars buit is dead and silent. The jinx goes on and it is now 21 Russian missions to Mars which have failed their main mission goals:

Phobos-Grunt
SpaceflightNow: Major General Vladimir Uvarov, a former space expert in the Russian military, told the Rossiiskaya Gazeta newspaper he has lost optimism in Phobos-Grunt’s chances for recovery.
“In my opinion, the Phobos-Grunt probe has been lost. This probability is very high. At any rate, it is much higher than the chances for reactivating the probe,” Uvarov told the newspaper. ….
With 11 tons of toxic hydrazine and nitrogen tetroxide propellant still in its fuel tanks, Phobos-Grunt’s potential re-entry is stirring concerns of space experts after two high-profile returns of large satellites in September and October.

The jinx on Russia’s probes to Mars continues.
Phobos-Grunt launched successfully last night but failed to enter its departure trajectory when two engine burns failed – presumed due to computer problems. It is now in a “parking” orbit and the problem needs to be fixed within 3 days when its batteries will run out. The fuel tanks are still in place for the craft’s own thrusters and there is still thought to be some hope. If the problem cannot be fixed it will be the fourth successive failure of a Russian Mars mission.

Much Russian news just now from the Nord Stream pipeline in the Baltic going live today to an ambitious and critical Mars mission which will launch late today (November 8th).
Russia’s last interplanetary launch of a probe to Mars in 1996 failed at launch. Prior to that in missions to the larger of Mars’ 2 moons, Phobos 1 was launched on July 7, 1988 and Phobos 2 on July 12, 1988. Communication with Phobos 1 was lost in September 1988. Phobos 2 operated normally till it was within 50m of the surface of Phobos and again communication was lost in March 1989.
In the meantime the US Mars Rover has operated on Mars for thousands of hours, Chinese and Indian probes have reached the moon and a Japanese probe has brought back some minute quantities of matter from an asteroid. The Russians have been short of financing and are now trying to regain the pre-eminence they once had. To have the Chinese planting flags on the moon in 3 or 4 years would be unbearable.
Russian missions to Mars have never yet been completely successful and the launch on November 8th as part of the Phobos-Grunt (Фобос-Грунт meaning Phobos -soil) project is carrying a great deal of Russian prestige and – more importantly – the future of the Russian space program.
