Quote:Almost All Recent Global Warming Caused by Green Air Policies – Shock Revelation From NASA

From the DAILY SCEPTIC

The world of climate science is in shock following extraordinary findings from a team of high-powered NASA scientists that suggest most of the recent global temperature increases are due to the introduction of draconian fuel shipping regulations designed to help prevent global warming. The fantasy world of Net Zero is of course full of unintended consequences, but it is claimed that the abrupt 80% cut in sulphur dioxide emissions from international shipping in 2020 has accounted for 80% of global warming since the turn of the decade. Although the extra heat is described as “transient”, the warming is extraordinary and is expected to rise during the 2020s at a rate of 0.24°C a decade, 20% higher than the claimed warming trend since 1980.

The news is likely to cause considerable concern among the mainstream climate hoaxers in media, academia and politics. They have had a field day of late by pointing to rises in temperature as evidence for their evidence-free prediction that the climate is in danger of imminent collapse. But the NASA scientists, working out of the Goddard Space Flight Centre, predict a trend of rising temperatures due to the IMO2020 regulations going forward, and state, “the 2023 record warmth is within the ranges of our expected trajectory”.

The science behind the NASA findings, which have been published in Nature, is simple. Fewer fuel particles injected into the atmosphere reduce cloud droplet density and this leads to clouds that reflect less solar radiation back into space. As the scientists note: “IMO2020 effectively represents a termination shock for the inadvertent geoengineering experiment through a reverse marine cloud dimming through reducing cloud droplet number concentration.” In the course of their work, the team calculated large particle reductions in major shipping routes in the North Atlantic, the Caribbean Sea and the South China Sea.

The NASA paper is likely to be fiercely contested, not least because it blows holes in all the attribution pseudoscience attempting to blame recent temperature rises and individual weather events on human-induced increases in carbon dioxide. Already the climate activists at the Potsdam Institute for Climate Impact say the observation period is too short, and man-made greenhouse gases continue to play the decisive role in climate change. Much of this thinking, that provides the ’settled’ science base for the planned Net Zero collectivisation, is supported by the UN’s Intergovernmental Panel on Climate Change. The IPCC promotes the view that almost all climate change since around 1900 is caused by the activities of humans. This unproven opinion looks shakier by the day. The NASA scientists have forced the issue of particles, or aerosols, to the centre of the climate debate, although there are other explanations for the recent rise in temperatures. These include a now departing strong El Niño, and possible changes in the upper atmosphere caused by the huge injection of water by the early 2022 Hunga Tonga submarine eruption.

The El Niño effect is well known and strong past oscillations, which involve global transfers of heat from oceans to the atmosphere, have shown short-term temperature spikes. As the current El Niño declines, to be likely replaced in short order by the cooling effects of a La Niña, there are signs that sea temperatures are falling. It will be up to the scientists to fight it out over what has played a more significant role in recent temperature rises – aerosols or El Niño – with some backing for third place Hunga Tonga. Moving further out in the betting – odds lengthening all the time, it seems – is the inventive notion that humans control the overall climate by burning hydrocarbons. What is clear, of course, is that climate is impossible to predict. The recent temperature rise is tiny and well within the natural variation seen across all known and reliable records. When it comes to making political decisions about human society, computer models that claim to replicate and forecast future climate trends need careful examination, while in the hands of powerful people with wrongheaded or even sinister agendas they are potentially dangerous.

The effect of the Hunga Tonga eruption continues to intrigue some scientists, although their curiosity is not reciprocated by the all-in mainstream CO2 promoters. Recently a team of Australian climatologists used the eruption, which increased the amount of water vapour in the stratosphere by up to 10%, as a ‘base case’ for further scientific work. Working out of the University of New South Wales, they reported that volcanoes blasting water vapour – a strong if short-lived ‘greenhouse’ gas – into the high atmosphere, “can have significant inputs on the climate system”. In fact they found that surface temperatures across large regions of the world could increase by over 1.5°C for several years, although some areas could cool by up to 1°C.

Yet more fascinating, conflicting and debatable climate science that under no circumstances should be drawn to the attention of the general public.
