New Study: Greenland Cooled by -0.11°C From 2000-2019 – Including All Ice Free And Ice Covered Areas

Any 21st century ice melt across Greenland cannot be due to an accelerated warming trend, as the island as a whole has been cooling since the 1990s.

New research analyzes two decades of Greenland land surface temperature (LST) data. Contrary to the popular narrative of a significant warming trend, Greenland has instead cooled from 2000-2019 at a rate of -0.055°C per decade.

Southern Greenland also cooled from 1958-2001, suggesting the region has been cooling for over 60 years.

Any recent ice melt in Greenland thus cannot be due to surface warming, as LSTs have undergone a cooling trend in both ice free and ice covered areas.

‘Energy-Limited Resources’: Huge Swaths Of America Face Blackout Risks If Winter Is Bitter, Grid Watchdog Warns

From the DAILY CALLER

Hundreds of millions of Americans risk experiencing power shortages this winter if weather conditions are harsh, according to a new report published by the North American Electric Reliability Corporation (NERC), a power grid watchdog.

Nearly all residents of the Northeast, Texas and Midwest could face energy shortfalls in the event of a colder-than-usual winter, the NERC report states. The lack of grid reliability is driven largely by growing electricity demand as well as the replacement of coal-fired and older natural gas-fired generators with energy-limited resources such as solar power. (RELATED: ‘Animal Protein Overconsumption’: UN Climate Confab Attendees Urge Countries To Implement Tax On Meat)

“Foreseeable extreme cold temperatures have the potential to push the existing natural gas supply infrastructure to maximum capacity,” the report warns. “Serving winter load is becoming more challenging and complex as coal-fired and older natural gas-fired generators retire and are replaced by variable and energy-limited resources.”

NERC’s 2024–2025 WRA finds much of North America at an elevated risk of #energy shortfalls in extreme conditions. No areas are identified as having a high risk and all areas are expected to have adequate resources under normal #winter peak load conditions. https://t.co/TOPhkCZumt pic.twitter.com/kANLz4dasl

The expansion of power-hungry data centers has led to a surge in electricity demand, according to the NERC study, with consulting firm Bain projecting utilities could have to increase their annual power generation by as much as 26% by 2028. Meanwhile, the Biden-Harris administration has sought to reduce natural gas and coal-fired power generation, finalizing a rule in April requiring that existing coal plants use carbon capture and storage to control 90% of their carbon emissions by 2032 if they want to stay running past 2039, and that certain new natural gas plants cut their emissions 90% by 2032, according to the Environmental Protection Agency (EPA).

Grid operators have requested the EPA nix the power plant rule in order to protect long-term energy dependability, with four major regional operators filing an amicus brief in support of red states’ legal challenge against the rule, stating it would jeopardize the grid’s ability to reliably meet American energy needs.

Mark Christie — a top power grid regulator — wrote a letter to lawmakers in August claiming the EPA rule could be “catastrophic.”

“If the EPA’s new power plant rule survives court challenge, it will force the retirements of nearly all remaining coal generation plants and will prevent the construction of vitally needed new combined-cycle baseload gas generation,” Christie wrote. “This loss of vitally needed dispatchable generation resources will be catastrophic.”

The EPA and Federal Electric Reliability Corporation did not immediately respond to requests for comment.

“the United States has suffered a “precipitous increase” in hurricane strikes”

“Is global warming to blame for the last two horrific hurricane seasons?

Yes, says Judith A. Curry, a professor of atmospheric sciences at the Georgia Institute of Technology.

As a result of global warming, hurricane seasons now are five days longer on average than they were 100 years ago, Curry said. In addition, the United States has suffered a “precipitous increase” in hurricane strikes in the last 10 years.”

Apr 15, 2006, page 61 – The Los Angeles Times at Newspapers.com

This was right at the beginning of the longest hurricane drought in US history.

“Hurricanes, large and small, have eluded U.S. shores for record lengths of time. As population and wealth along parts of the U.S. coast have exploded since the last stormy period, experts dread the potential damage and harm once the drought ends.

Three historically unprecedented droughts in landfalling U.S. hurricanes are presently active.

A major hurricane hasn’t hit the U.S. Gulf or East Coast in more than a decade. A major hurricane is one containing maximum sustained winds of at least 111 mph and classified as Category 3 or higher on the 1-5 Saffir-Simpson wind scale. (Hurricane Sandy had transitioned to a post tropical storm when it struck New Jersey in 2012, and was no longer classified as a hurricane at landfall, though it had winds equivalent to a Category 1 storm.) The streak has reached 3,937 days, longer than any previous drought by nearly two years.”
