Rivers speeding up Arctic ice melt at alarming rate, experts say
https://phys.org/news/2022-01-rivers-ar ... perts.html
by Mikayla Kelley,, University of Arizona

Irina Panyushkina grew up in Siberia, near the Arctic Circle. She was raised on stories of explorers trudging through seas of ice to reach the North Pole.

Now, she is a climate scientist and associate research professor of dendrochronology in the University of Arizona Laboratory of Tree-Ring Research. And she is trying to understand how a warming world is transforming the place she once called home.

Someday, the Arctic Ocean may no longer host ice, since the northern regions of the world are warming are faster than the rest—a trend scientists refer to as Arctic amplification. As Arctic ice melts, new opportunities and challenges for humans will arise, researchers say.

Freshwater flowing into the Arctic Ocean from the continent is thought to exacerbate Arctic amplification, but the extent of its impact isn't fully understood. New research led by Panyushkina measures how the flow of the Yenisei River—the largest freshwater river that flows into the Arctic Ocean—has changed over the last few hundred years, and describes the impact freshwater has had on the Arctic.

Australia soars to 50 degrees for first time this century


Image
Temperatures of 50°C or higher have been recorded in at least two locations in the northwest of Western Australia this Thursday, January 13, 2022, with a high of 50.5°C at Roebourne Airport.

This was the first time this century that any Australian location has reached the 50-degree mark.

The 50.5°C reading was the equal second-hottest Australian temperature ever recorded.

The 50.5°C equalled the hottest temp ever recorded in the state of Western Australia.

The 50.5°C reading came within 0.2°C of the all-time Australian record, which was 50.7°C at Oodnadatta (SA) in January 1960.

It's the first time since 1998 that any official weather station anywhere in Australia has reached the half-century. In other words, the Roebourne Airport reading is Australia's hottest recorded temperature in 24 years.

'A Great Step': Biden Admin Launches Clean Energy Corps
by Julia Conley
January 14, 2022

https://www.commondreams.org/news/2022/ ... ergy-corps

Introduction:
(Common Dreams) A new program launched by the Biden administration on Friday will hire 1,000 Americans to help expand the country's clean energy infrastructure, a step the White House says is "critical to achieving the president's goal of 100% carbon pollution-free electricity by 2035."

Workers in the Clean Energy Corps will work in areas including engineering, physical science, legislative affairs, and contract management and will work on large-scale projects including the administration's Building a Better Grid initiative.

That project, using funds allocated by the $1.2 trillion Infrastructure Investment and Jobs Act which passed last year, will deploy new transmission lines to send solar and wind power to communities across the country and make the energy grid more "safe, reliable, and resilient" to extreme weather events.

"It's truly a remarkable time to be at the Department of Energy as we set off to implement the historic $62 billion in clean energy investments," said Secretary of Energy Jennifer Granholm. "The launch of our Clean Energy Corps is the latest definitive step along our path to making transformational changes to America's energy sector and ensuring a clean energy future for all. We're calling on people of all backgrounds and career levels who understand the urgency of tackling climate change now, and are eager to join the team that is best positioned to do so."

Rep. Pramila Jayapal (D-Wash.) called the creation of the corps "a great step" toward expanding the use of renewable energy and significantly reducing the country's carbon emissions.

How Greed and Politics are Slowing the Switch to Renewable Energy
Andrew Dessler
January 17, 2022

https://thebulletin.org/2022/01/how-gre ... le-energy/

Introduction:
(Bulletin of Atomic Scientists) It is (with apologies to Charles Dickens) the best of times; it is the worst of times.
Thanks to fossil fuels, billions of people in 2022 enjoy lives of wealth, comfort, and material possessions unimaginable before the industrial revolution.

But fossil fuels have their dark side. You might think you understand that, but it’s likely fossil fuels are even worse for the world than you think. Let’s start with climate change. Contrary to what you might hear listening to Fox News, the scientific understanding of climate change is good and it is progressing at exactly the rate predicted decades ago by Exxon.

What you probably don’t realize is how massive these changes may be. In the depths of the last ice age 20,000 years ago, the Earth was only 6 degrees Celsius colder than it is today. That world—with thousands of feet of ice sitting over much of North America, sea level 300 feet lower, and completely different ecosystems—would be unrecognizable to those living on today’s Earth.

This helps us put predictions of future warming into context. The chart below (see link above the quote box) shows predictions for the twenty-first century, but instead of units of temperature, I have plotted units of ice ages, where one ice age unit equals 6 degrees Celsius. Business-as-usual emissions gives us about 3 degrees Celsius of warming in 2100—about half of one ice-age unit. Given how much the Earth has changed since the last ice age, 3 degrees Celsius of warming may well remake the planet, leading to an Earth in 2100 as unrecognizable to us today as the world of the last ice age.

Scientists Find Evidence that Climate Change is Linked to Early Birth and Damage to Babies’ Health
January 20, 2022

https://grist.org/extreme-weather/clima ... ists-find/

Introduction:
(Grist) The climate crisis is damaging the health of fetuses, babies, and infants across the world, six new studies have found.
Scientists discovered increased heat was linked to fast weight gain in babies, which increases the risk of obesity in later life. Higher temperatures were also linked to premature birth, which can have lifelong health effects, and to increased hospital admissions of young children.

Other studies found exposure to smoke from wildfires doubled the risk of severe birth defects, while reduced fertility was linked to air pollution from fossil fuel burning, even at low levels. The studies, published in a special issue of the journal Pediatric and Perinatal Epidemiology, spanned the globe from the United States to Denmark, Israel, and Australia.

“From the very beginning, from preconception, through early childhood into adolescence, we’re starting to see important impacts of climate hazards on health,” said Gregory Wellenius, who edited the issue with Amelia Wesselink, both professors at the Boston University School of Public Health.
“This is a problem that affects everybody, everywhere. These extreme events are going to become even more likely and more severe with continued climate change [and this research shows] why they’re important to us, not in the future, but today.”

I've just come to the realization that charcoal is one of the greenest sources of energy for planet Earth. It's renewable, it's emissions literally greenify Earth as it's mostly compressed carbon and it's very cheap to produce. Solar & wind power are probably one of the least green energy sources. Talk about double speak. I am tired of words that don't actually mean what they mean. I feel like I've been fooled for a very long time. :oops:

Interesting that the industry apparently knew about it and tried to capitalize on it. Seems like it didn't work so well for them.

Anyway, Earth is getting greener each and every day and I can't wait until this becomes a "bad thing" and turns itself into headlines and, of course, seed for more panic.
And, as always, bye bye.
