Vast Body Of Scientific Data For Past 2,000 Years Affirms Sun, Not CO2, Controls Climate

Overall, we rate Principia Scientific International (PSI) a strong conspiracy and Pseudoscience website that promotes anti-vaccine propaganda and frequent misinformation regarding climate change.

Vast Body Of Scientific Data For Past 2,000 Years Affirms Sun, Not CO2, Controls Climate

Principia Scientific International (PSI) is an organization based in the United Kingdom which promotes fringe views and material to claim that carbon dioxide is not a greenhouse gas. PSI was formed in 2010 around the time they published their first book, titled Slaying the Sky Dragon: Death of the Greenhouse Gas Theory. [1]

PSI claims it provides its members with a “reliable port of call to ascertain the facts behind the news stories to better judge whether information being presented by third parties is accurate information and reflects a balanced view of all facets of the subject.” [2]

The PSI website says the organization is “for everyone who supports the traditions [sic] scientific method against the rise of sinister and secretive government funded 'post normal science'.”

John O'Sullivan is a UK-based climate denialist blogger, writer and the sole active director of Principia Scientific International - a membership group promoting fringe views on climate change science and role of carbon dioxide in the atmosphere. O'Sullivan, a former school teacher, claims the greenhouse effect caused by carbon dioxide is unproven and that human-caused climate change is a “fraud”.

‘A Little Shocking’: Ocean Currents Are Speeding up Significantly, Study Finds

The world's oceans are getting faster, a new study has found. gcalebjones / Public Domain
The world's oceans are moving faster, and researchers think it might be another sign of the climate crisis.

A new paper, published in Science Advances Wednesday, found that 76 percent of the top 2,000 meters of the ocean appears to have sped up since the 1990s, largely because of wind speeds. And the ocean's speedup is more than can be explained by "natural variability."

"The Earth is our patient, and you look for symptoms of how it is reacting to anthropogenic greenhouse gas forcing," study coauthor and National Oceanic and Atmospheric Administration researcher Michael McPhaden told The Washington Post. "This is another symptom."

Each ocean current moves as much water as all the world's rivers combined, Science Magazine explained. Researchers found that between 1990 and 2013, the energy of these currents increased by 15 percent per decade.

"This is a really huge increase," Susan Wijffels, an oceanographer at the Woods Hole Oceanographic Institution who was not involved with the paper, told Science Magazine.

At the same time, wind speed has increased by around two percent per decade and ocean current speed by around five percent per decade, according to The Washington Post.

NASA flights detect millions of Arctic methane hotspots

Summary:
In a new study, scientists with NASA's Arctic Boreal Vulnerability Experiment (ABoVE) used planes equipped with the Airborne Visible Infrared Imaging Spectrometer -- Next Generation (AVIRIS -- NG), a highly specialized instrument, to fly over some 20,000 square miles (30,000 square kilometers) of the Arctic landscape in the hope of detecting methane hotspots. The instrument did not disappoint.

The World Meteorological Organisation says there's a growing chance that global temperatures will rise by more than 1.5C over the next five years, compared to pre-industrial levels.

It assesses a 20% chance the threshold will be broken in one year before 2024 and a 70% chance it will be broken in one or more months in those five years.

Scientists Just Updated One of the Most Important Climate Metrics, and It's Bad

Next month, after a yearlong delay because of the pandemic, the U.N. Intergovernmental Panel on Climate Change (IPCC) will begin to release its first major assessment of human-caused global warming since 2013. The report, the first part of which will appear on 9 August, will drop on a world that has starkly changed in 8 years, warming by more than 0.3°C to nearly 1.3°C above preindustrial levels.

Abstract wrote:The observed trend in Earth’s energy imbalance (TEEI), a measure of the acceleration of heat uptake by the planet, is a fundamental indicator of perturbations to climate. Satellite observations (2001–2020) reveal a significant positive globally-averaged TEEI of 0.38 ± 0.24 Wm−2decade−1, but the contributing drivers have yet to be understood. Using climate model simulations, we show that it is exceptionally unlikely (<1% probability) that this trend can be explained by internal variability. Instead, TEEI is achieved only upon accounting for the increase in anthropogenic radiative forcing and the associated climate response. TEEI is driven by a large decrease in reflected solar radiation and a small increase in emitted infrared radiation. This is because recent changes in forcing and feedbacks are additive in the solar spectrum, while being nearly offset by each other in the infrared. We conclude that the satellite record provides clear evidence of a human-influenced climate system.

A new report from the Intergovernmental Panel on Climate Change (IPCC) finds that the world may warm by 1.5°C by the early 2030s, much earlier than previously estimated. It’s terrible news for the Pacific. With temperatures rising above 1.5°C, Pacific communities are likely to experience increasingly devastating climate change impacts.

The key takeaway from the IPCC report is that the more we know, the worse it looks. The planet is now already between 0.8°C and 1.3°C warmer than in pre-industrial times – moving frighteningly close to the 1.5°C threshold.

Aug 16 (Reuters) - U.S. officials for the first time on Monday declared an official water shortage for the massive Lake Mead reservoir, triggering supply cuts to parts of the drought-stricken Southwest, as 10 Western governors appealed for federal drought disaster aid.

The shortage will reduce water apportionments to Arizona, Nevada and Mexico for the year beginning in October, the U.S. Bureau of Reclamation, an Interior Department agency, said in a statement.

Arizona will lose 18% of its annual apportionment, while Nevada will see cuts of 7%. Apportionments to Mexico, which are required under a 1944 treaty, will be cut by 5%.

Separately, 10 Western governors urged President Joe Biden to declare a federal drought disaster in their states, qualifying farmers and ranchers to seek special assistance "beyond what is available through existing emergency programs."

July 2021 was the warmest July on record.
Eight of the largest fires have occurred in the last four years.

Abstract. Global surface temperature in 2020 was in a virtual dead-heat with 2016 for warmest
year in the period of instrumental data in the Goddard Institute for Space Studies (GISS) analysis.
The rate of global warming has accelerated in the past several years. The 2020 global temperature
was +1.3°C (~2.3°F) warmer than in the 1880-1920 base period; global temperature in that base period is a reasonable estimate of ‘pre-industrial’ temperature. The six warmest years in the GISS record all occur in the past six years, and the 10 warmest years are all in the 21st century. Growth rates of the greenhouse gases driving global warming are increasing, not declining.

The fires in Siberia are larger than all the other fires around the world combined. Some will remember the 2000 methane pingos found in Siberia years ago
