Antarctica’s Red Flag Warning

Antarctica has moved to “the front of the line” as a global warming threat that’s already well beyond expectations, and it’s happening fast. Based upon statements by polar scientists over the past 18 months, it warrants a Red Flag Warning, meaning higher than expected risks of catastrophic meltdown within current lifetimes. This meets criteria for the latest international concern surrounding climate change: “When is enough, enough” for world leaders to take to heart the risks of ecosystem failures and take extraordinary, drastic, unprecedented measures in unison to hopefully head off the onset of a maniacal worldwide climate system.

Fundamental Change In The Climate: ‘The World Is Coming Apart Before Our Eyes’

The situation with respect to the climate crisis is developing rapidly. Each new study seems to bring worse news. In addition, the media is rife with climate denial and misinformation. To help us understand what is happening on this planet, Clearing the FOG speaks with environmental journalist Robert Hunziker. Hunziker follows climate studies published in scientific journals and translates them into a language the average person can understand. He reports that top scientists are saying there has been a fundamental shift in the climate. Rainforests and tundras are now spewing carbon instead of sequestering it, and the oceans have reached their capacity for storing the planet's heat. Cascading weather events are making areas of the world uninhabitable.

Antarctica On Alert!

Over the past year, several studies about highly dangerous signals of Antarctica on the edge of major abrupt change have appeared in scholarly publications. These studies in premier publications expose rapid changes, e.g. (1) discovery of the western Antarctic Peninsula as one of the fastest warming places on Earth (2) ocean currents threaten to collapse Antarctic Ice Shelves (3) present day mass loss rates are a precursor for West Antarctic Ice Sheet collapse (4) an unexpected ice collapse hints at worrying changes on the Antarctic coast. The new scientific narrative has scientists very nervous. Abrupt changes have become more common in the climate system, but Antarctica is one region that nobody wants to hear about “abrupt change,” especially with the potential impact nearly impossible to analyze with certainty.

The Drying Planet

As the planet gets hotter and its reservoirs shrink and its glaciers melt, people have increasingly drilled into a largely ungoverned, invisible cache of fresh water: the vast, hidden pools found deep underground. Now, a new study that examines the world’s total supply of fresh water — accounting for its rivers and rain, ice and aquifers together — warns that Earth’s most essential resource is quickly disappearing, signaling what the paper’s authors describe as “a critical, emerging threat to humanity.” The landmasses of the planet are drying. In most places there is less precipitation even as moisture evaporates from the soil faster.

Emergency Summit Regarding Antarctic Meltdown

Hundreds of scientists gathered in Australia for an “emergency summit” within the auspices of the inaugural Australian Antarctic Research Conference d/d November 2024. This gathering of 450 mostly “early-career” polar scientists flexed scientific muscles to alert the world to the what’s happening to our planet, taking off the gloves and coming out swinging. They claim we’re got a bigger problem than generally realized: “Efforts to slow down climate change through coordinated global action are paramount to protect the future of Australia, Antarctica, and our planet,” Ibid.

Politicians Continue To Fail On Climate; We Must Fight For A Livable Future

The Intergovernmental Panel on Climate Change issued its sixth report in three phases beginning in August, 2021 and concluding in April 2022. The first report declared that the climate crisis is unquestionably due to human activity and called the situation a 'Code Red for Humanity.' The second and third parts indicated that not enough action is being taken not just to mitigate the crisis but also to adapt to it. Clearing the FOG speaks with Professor Benjamin Horton of the Earth Observatory of Singapore about the gravity of the crisis, including that some impacts such as sea level rise are irreversible for the foreseeable future, the importance of activism by scientists to inform the public and push policy makers and how to keep fighting for a more livable future.

Increase In Atmospheric Methane Set Another Record During 2021

For the second year in a row, NOAA scientists observed a record annual increase in atmospheric levels of methane, a powerful, heat-trapping greenhouse gas that’s the second biggest contributor to human-caused global warming after carbon dioxide. NOAA’s preliminary analysis showed the annual increase in atmospheric methane during 2021 was 17 parts per billion (ppb), the largest annual increase recorded since systematic measurements began in 1983. The increase during 2020 was 15.3 ppb. Atmospheric methane levels averaged 1,895.7 ppb during 2021, or around 162% greater than pre-industrial levels. From NOAA’s observations, scientists estimate global methane emissions in 2021 are 15% higher than the 1984-2006 period.

The Urgent Need For Climate Action

Although the worst effects of catastrophic climate change lie in the distant future, there are recent warnings that tell us that a climate disaster may be nearer than we thought. The Arctic and Antarctic regions are warming more than twice as fast as the remainder of the world. In the Antarctic region, the vast Thwaites glacier, sometimes called "the Doomsday Glacier", has recently exhibited so many cracks that scientists fear that it may shatter into small pieces like a windscreen. If this happens, the event may trigger the collapse of other nearby glaciers through a mechanism called "Marine Ice Cliff Instability". This could mean several meters of sea level rise, threatening all coastal cities throughout the world. Other warnings come from the Arctic.

NOAA Predicts One-Foot Sea-Level Rise By 2050

Ocean levels along the U.S. coastline are projected to rise by an average of 10 to 12 inches over the next three decades, worsening the threat of flooding in dozens of highly populated cities, according to a new report released Tuesday by the National Oceanic and Atmospheric Administration and other federal agencies. The additional foot of sea-level rise that millions in the U.S. are predicted to face by mid-century is equivalent to the amount experienced in the previous hundred years—a manifestation of the climate crisis that scientists attribute to unmitigated greenhouse gas (GHG) pollution driven primarily by the burning of fossil fuels. This intensification of rising seas "will create a profound increase in the frequency of coastal flooding, even in the absence of storms or heavy rainfall," said NOAA.

When To Build Sea Walls

During the month of December 2021 two warnings of impending sea level rise were issued by highly respected groups of climate scientists. These are professional scientists who do not deal in hyperbole. Rather, they are archetypical conservative serious-minded scientists who follow the facts. The most recent warning on December 30th is of deteriorating conditions at the Arctic and Greenland. The second warning is the threatening collapse in Antarctica of one of the largest glaciers in the world. As these events unfortunately coincide so close together, one at the top of the world, the other at the bottom, should coastal cities plan to build sea walls? The scale of time and material and costs to build seawalls is nearly overwhelming. In fact, it is overwhelming.

The Surfside Condo Collapse And Its Environmental Warning Signals

The hunt is on to find out why the Champlain Towers South in the Miami suburb of Surfside collapsed. On Friday, reports surfaced that in 2018 Frank P. Morabito, an engineer, assessed the 40-year old building and reported that he had found "major structural damage" in a concrete slab below the pool deck, near the base of the tower that collapsed. Morabito had recommended repairs, including waterproofing below the pool deck and entrance way. These repairs had not been carried out when the collapse occurred. Morabito also found "abundant cracking" in the columns and pillars that support the parking garage located under the pool deck. On Saturday, Surfside mayor Charles Burkett ordered the evacuation of residents of the sister Champlain Towers North next door.

Are We Really Past The Point Of No Return On Climate?

A controversial new climate study has found that, even if greenhouse gas emissions were halted tomorrow, it might not be enough to stop temperatures from continuing to rise. The study, published in Scientific Reports Thursday, was conducted by two researchers at the BI Norwegian Business School. They used the ESCIMO climate model to determine that, even if emissions ceased tomorrow, the permafrost would continue to thaw for hundreds of years. "According to our models, humanity is beyond the point-of-no-return when it comes to halting the melting of permafrost using greenhouse gas cuts as the single tool," lead author and professor emeritus of climate strategy Jorgen Randers told AFP.

Iceland Holds Funeral For Glacier Destroyed By Climate Change

To put things into perspective, if the Antarctic ice sheet melted, it would raise global sea levels by around 200 feet. We’ve already seen a noticeable loss of mass on the west end of the glacier, one of the many reasons why we should all be screaming. And Iceland most certainly is: Locals there just held a politically charged funeral for a 700-year-old glacier called Okjökull. Jökull is Icelandic for glacier, so that portion of Okjökull’s name has been removed, and what remains is now referred to as Ok. But Ok is not OK.

The Great Flood

How many times will we rebuild Florida’s cities, Houston, coastal New Jersey, New Orleans and other population centers ravaged by storms lethally intensified by global warming? At what point, surveying the devastation and knowing more is inevitable, will we walk away, leaving behind vast coastal dead zones? Will we retreat even further into magical thinking to cope with the fury we have unleashed from the natural world? Or will we respond rationally and radically alter our relationship to this earth that gives us life?

U.S. Costal Communities Face More Than $400 Billion In Seawall Costs By 2040

20 June 2019– Coastal communities in the contiguous U.S. face more than $400 billion in costs over the next 20 years, much of it sooner, to defend coastal communities from inevitable sea-level rise, according to a new report released today by the Center for Climate Integrity in partnership with the engineering firm, Resilient Analytics. This is approaching the cost of the original interstate highway system and will require the construction of more than 50,000 miles of coastal barriers in 22 states by 2040, half the time it took to create the nation’s iconic roadway network.
