Rapid Ice Melt on Eagle Island and Warm Rivers Converge Beneath the Thwaites Shelf
In an event similar to the massive one day Greenland melt last year, Eagle Island on the Antarctic peninsula lost about 20% of its ice cover in the space of a nine day heat wave in mid-February. As the NASA image shows, much of the land beneath the island’s ice cap was exposed as about 4 inches of snowpack melted in a fortnight. Pools of meltwater opened up on the surface of the surface remaining snow.
The continent recorded it’s all time high during this period, reaching 69.8 F. Climate scientists say they have seen this trend in Greenland and Alaska in recent years, but this is a first for Antarctic.
This February heatwave was the third major melt event of the 2019-2020 summer after similar events in November and January. Says Nichols College glacieologist Mauri Pelto “If you think about this one event in February, it isn’t that significant. It’s more significant that these events are coming more frequently.“
In a related story from science journal
Nature, a new expedition to Antarctica’s troubled Thwaites Glacier has
discovered three streams of warm water running beneath the ice shelf, melting
the glacier from below. Pine Island glacier, which has just calved an ice berg
the size of Manhattan, is sending a river of warm water south to the Thwaites,
while two other under-ice rivers are merging on the eastern side, once thought
to be the more stable region of the formation.

ADD DUST STORMS AND DEVASTATING HAIL TO AUSTRALIA’S APOCALYPTIC TROUBLES:
The wildfires that have consumed
Australia’s southeast, including areas around it’s major population centers,
have gotten plenty of media coverage. That is due in large part to the good
visuals that accompany this type of story. An area about the size of Virginian
has been burned. Millions of animals and birds have died. The economic toll had
not even begun to be calculated when the area was hit with a massive dust storm
followed by an apocalyptic hail storm.
2019 was the hottest, driest year on
record in Australia, which is saying something. Summer is only half over. With
no moisture in the air, the intensity of these fires is hard to describe.
INDONESIA RECORD STORMS / JAKARTA SINKS
Beginning New Year’s Day, Jakarta has
been inundated by catastrophic storms that brought intense rainfall and lethal
flooding to the city of 30 million, with 15 or 20 inches coming in 24 hours. Even
in a megalopolis prone to flooding, this storm is in a class of its own.
Millions have been evacuated. The situation of course, is exacerbated by stupid human tricks, because massive
quantities of groundwater have been sucked out from beneath the city. As is
often the case, there is both too much water and not enough to drink.
Monsoons are normal in this region, but the new weather patterns bring much greater quantities of rain over the course of fewer, less predictable storms.

OCEAN TEMPERATURES HOTTEST EVER IN 2019 AND CLIMBING FASTER
The heat in the world’s oceans reached a new record
level in 2019. Although 2019 was only the “second warmest” on record for
atmospheric temperatures, the oceans are heating up faster than ever. Oceans
absorb and store 90% of solar heat energy. Hotter seas cause more severe storms and further contribute to rising seas through
thermal expansion and kill marine life.
For the most part, people who accept climate change (and even those who understand that it is caused by humans remain unaware of the fact that this is a climate emergency that has been under-stated rather than over-stated. Seen globally however, the realities may be more persuasive. This is a small sampling of global events and conditions from the past year.
ARCTIC AMPLIFICATION: The Arctic region is warming twice as fast as the rest of the planet. The global consequences in terms of disruption to wind and weather patterns are hard to overstate.
ALBEDO FEEDBACK CYCLE: Self-perpetuating feedback cycle, as sea ice melts, more solar radiation heats the open water, ice melts faster.
PERMAFROST FEEDBACK CYCLE: Permafrost is thawing, releasing CH4 and CO2 into the atmosphere, causing more warming, causing more permafrost melt. The quantity of CH4 trapped in permafrost is unknown.
SLOWING AMOC (Atlantic Meridional Overturning Circulation): A significant tipping point, the global ocean circulation that drives the Gulf Stream has been slowing. The ocean current is a critical factor in regulating temperatures.
MASSIVE MARINE HEAT WAVE: The “Blob “ is back. This Pacific heat wave is the second worse ever. The worst was the Blob of 2014 – 2016, which lasted three years, causing serious disruption to marine ecosystems and marine life on the west coast, not to mention the largest toxic algae bloom in the history of the US West Coast. Marine heat waves are increasing in frequency, compromising underwater ecosystems which as kelp forests and coral reefs.

A new report from
National Oceanic and Atmospheric Administration summarizes the economic consequences.
COASTAL INUNDATION: Major urban
centers face rapid ocean rise, including Charlotte, NC, Miami, Norfolk, VA,
Shanghai, China, Bangladesh, Alaska, Mumbai, Solomon and other Pacific Islands.
GLOBAL WILDFIRES/DEFORESTATION: Supercharged Wildfires burn hotter and are harder to control. Amazon gets the coverage, but out of control wildfires burned in 2019 in Australia, Bolivia, Chile Indonesia, Cyprus, Siberia, Alaska, Southern Europe and California. Firenados are increasingly common. Global outbreaks of wildfires is stressing resources. Megatons of carbon are released into the atmosphere. The Wildfire/Deforestation Feedback Cycle pours more carbon into the atmosphere and accelerates global warming.

UNPRECEDENTED HURRICANE /CYCLONE BEHAVIOR: Hurricanes and storms of all types are more intense, move more slowly, contain more moisture (causing more damage), and intensify more rapidly. Damage over the past few years is unprecedented. For three hurricane seasons in a row, storms with record-breaking rainfall have caused catastrophic flooding in the southern United States:

SHARP INCREASE IN METHANE RELEASES. Atmospheric CH4 is highest in 800,000 years, generating more greenhouse gases via Permafrost Thaw Feedback Cycle #2.
Methane is leaking
from gas wells in Texas and elsewhere, while new sources within the permafrost
are spewing even more into the atmosphere.
Global methane concentrations increased 250 % since pre-industrial time.
US FARM CRISIS: Record rainfall and flooding has gotten Midwestern farmers closer to recognizing the climate emergency. “We’re seeing things we’re not used to seeing.”
The Amazon rainforest is on fire again, driven by the Southern Hemisphere’s version of Trumpian plunder monkeys. As of late August, the fires have been burning for several months, and consumed a record amount of rain forest. The number of fires identified so far this year is over 40,000.
Darkness in Sao Paulo. Smoke from fires hundreds of miles away darkened the skies of South America’s largest city, bringing on a doomsday sensation in Brazil’s capital city.
While previous record burning years were caused in part by cyclical drought, this year’s fires have been largely ignited by farmers and ranchers clearing more land. Loggers in particular are invading “protected” areas, emboldened by Bolsonaro’s rhetoric.
From January to July 2019, fires consumed 4.6 million acres, a 85% increase over last year.
To understand this story in context, note that it takes place as 1) yet another heat wave is hitting Europe, the third in as many months 2) Greenland lost about 1 billion tons of land ice in a single day 3) total loss of sea ice within 150 miles of Alaska’s coast is reported 4) Wildfires in Siberia continue into a fourth month as smoke drifts over Alaska and North America.
