Spring Global Warming Update

“I’m not ready for this. Not this early…”*

Louisiana: New Climate Refugees As Waters Close In

Only 15 miles south of New Orleans, the waters around Grand Island, Barataria,  Crown Pointe, and Jean Lafitte are continuing to rise, threatening long time residents of the bayou area.  About a football field worth of wetland disappears every two hours.

South Africa: Over 400 dead in “unprecedented” flooding:

Horrendous rains have brought lethal flooding and landslides that have displaced thousands the Durban, South Africa region. The humanitarian disaster, as always, is magnified by malfeasance on the part of the powers what is. More than a decade ago, poor families were relocated away from a new soccer stadium and dumped in a flood prone area, where they remain. Damages are currently estimated at $684 million and rising. The death toll will climb. 

Bering Sea: Warming Ocean Threatens Crab Fisheries

Add Alaskan snow crab to the growing list of marine animals  threatened by rapidly changing conditions on the ground, or, in this case, in the Bering Sea. Extreme ocean warming in the area around the Pribilof Islands  (between Siberia and Alaska) has crashed the population down nearly 90% from 2021 levels. Read the Article.

Siberia/Alaska: Methane / Permafrost Thaw Reshapes the Arctic

There is a lot of CH4 trapped beneath the surface of the planet, particularly under the permafrost in Siberia, Alaska and other Arctic regions. As the permafrost thaws, the gases trapped below it spew into the atmosphere, creating a climate feedback cycle with results that are observable in something close to real time. Visit the Page.

The Poles: Insane Temps At Both Poles

Late winter in the Arctic temperatures were about 70°F above the normal average at some measurement stations. Some near North Pole stations reported the beginning of melt. New heat records were also established in Antarctica with temperatures of over 50°F above the normal average in March. Visit the Page.

Great Barrier Reef: New Mass Bleaching Event

Another widespread die-off at the World Heritage site off the northern coast of Australia marks the sixth such catastrophe since 1998. This ongoing environmental disaster is driven by warming oceans and pollution. The most recent aerial survey shows almost no reefs across a 1,200km stretch unaffected by the elevated water temperatures.  See Australia’s New Normal video.

Great Salt Lake: Toxic Dust Events Loom In Utah

The inland sea that forms the iconic core of Utah’s Latter Day culture is in danger of disappearing as it reaches its lowest level. About half of the original lakebed area is now dry land  In the process, thousands of square miles of dry lake bed is exposed, laying open vast expanses of toxic dust.

India: Record Deadly Heat Begins The Year

Life-threatening heat waves are shattering temperature records, with highs reaching over 100°F. High temperatures are expected to climb to 10°F to 15°F above normal. 

Antarctica: Another Major Ice Shelf Collapse

East Antarctica’s Conger ice shelf – a floating platform the size of Rome – broke off the continent on March 15, 2022.

American West: Mega Drought Driving Water Emergencies

Lake Mead has dropped to an unprecedented low and other regional reservoirs have reached emergency levels as the western drought continues. Hydropower is likely to be curtailed and blackouts are expected. Read the Article.

Afghanistan: 5 Million Children At Risk of Starvation As Crops Fail In Historic Drought

Five million children near are starvation in Afghanistan amid the worst drought since records began. “When there is no rain the land is dry and we can’t grow anything … The drought has completely devastated our land.”

*Flagstaff, AZ resident watching her neighborhood go up in smoke, quoted April 21, 2022 in the New York Times.

Bordeaux: Wine Regions Scramble As Heat Threatens Grapes

Violent weather events—frost, hail, storms, rain at harvest, dry summers—have become more frequent. Slow to acknowledge the creeping disaster, French wine authorities have authorized planting of new varieties. 

Iceland: Land Mass Rising As Huge Glaciers Melt Away

Coastal water levels are dropping even as melting land glaciers dump tons of fresh water into the North Atlantic. As the immense weight of Iceland’s glacial ice mass disappears into the North Atlantic, the land beneath it is “bouncing back”, more or less springing up as the burden is removed. So seas seem to be dropping lower on the coasts of Iceland even though water level is relative to the land mass. Read the Article.

Australia: The Relentless Onslaught of the New Normal

The reality of calamitous sea level rise smashes into Sidney as tidal onslaught tears boats their moorings. Bondi and Clovelly beach clubs and hotels took a pounding from huge wind driven swells. The second major cleanup follows a major flooding event only three weeks ago.  It’s all part of Australia’s New Normal (see our video). 

Syria: Lethal Drought Continues Into Third Decade

The root cause of the so war in Syria was an unrelenting drought that brought farmers to their knees. It moves into its third decade as the worst in the Middle East for at least 1,000 years. Conditions have worsened in the past two years: Herds have been culled and crops are generally devastated. The iconic Khabur river is at record lows.. 

Argentina: Wildfires & Serial Heat Waves

After a scorching heatwave, Argentina is suffering another round  of raging wildfires that torched forests and farms across its northern regionAuthorities estimate early losses at a quarter billion dollars with 2 million acres torched. The region has been experiencing record heat this year, baking in unprecedented temperatures up to 113°F.

Kenya: Water Shortages, Dead Livestock and Ruined Harvests as Desertification Moves In

Kenya and the Horn of Africa are in the third year of failed rainy seasons as the desert takes back the land. 5.5 million children in the region are threatened by acute malnutrition. Millions of head of livestock have died of malnutrition and in Kenya, Forecasts indicate that below average rainfall will continue into the foreseeable future.

Brazil: Mass Rainforest Ecocide

The far right Brazilian administration has accelerated the plundering of indigenous lands; what environmental regulations remain are essentially gone. Many scientists now believe the critical forest carbon sink has crossed the final tipping point in terms of climate effects. When forests are cleared, another climate feedback cycle is triggered. 

Sahel: Sahara Moving South To Claim Central Africa

Life-threatening heat waves are shattering temperature records, with highs reaching over 100°F. High temperatures are expected to climb to 10°F to 15°F above normal. 

Indonesia: Papua’s Last Glacier Almost Gone

Little remains of the ironically named Eternity Glacier in Papua’s Jayawijaya mountains. The once might ice formation is expected to be gone by 2025.

Gulf Stream: AMOC continues to slow

The Gulf Stream carries warmer waters north, where they serve to moderate the climate of northern Europe. Look at the latitude of Western Europe and you will see how far north the nations that invaded North America are located compared to the US east coast. The global ocean current is driven by salinity changes in the northern sea, which causes surface waters to change density and sink (that’s basically how it works). When this mechanical process is disrupted, weather becomes unpredictable and extreme, extended events more common.

UNFORSEEN CONSEQUENCES: Changes due to massive glacier melt are surprising 

One of the most dangerous and visible effects of global heating is that sea levels are rising almost everywhere around the planet. Coastal areas such as the US Eastern Seaboard, Louisiana, Alaska, China, Bangladesh, Vietnam, Indonesia, Thailand, the Philippines and Japan are already becoming inundated by salt water, while Pacific Islands such as the Maldives and the Marshall Islands are facing existential choices.

Globally, average sea level has risen by more than a foot (20cm) since 1900, and the rate of rise has accelerated since 1990.

In general, seas are rising because the land ice on Antarctica, Greenland and other huge ice caps is melting faster than ever, and the trillions of tons of water locked up in the ice gushes into the oceans. The coastal ice shelves that have slowed the flow to the sea are collapsing. This is simple. Less obvious is the other major cause of sea level rise, which is that the volume of the global ocean is expanding as the waters warm. Just basic physics.

But (along with such phenomena as methane craters blowing holes in the thawing permafrost) there are unexpected developments that one might call counter intuitive.

In Iceland, coastal water levels are dropping even as melting land glaciers dump tons of fresh water into the North Atlantic each day. That is because as the immense weight of Iceland’s glacial ice mass disappears into the North Atlantic, the land beneath it is “bouncing back”, more or less springing up as the burden is removed. So seas seem to be dropping lower on the coasts of Iceland even though water level is relative to the land mass.

But this is more than just another entry in global warming fun facts. In terms of practical effects, the shallower bays and estuaries are becoming more treacherous to navigate for fishing vessels. While rising coastal waters can be contained to some degree by human infrastructure, there is no remedy for this scenario.

No one is winning in this tug of war.

 

iceland glaciers sea level change
As the graphic shows, this same process is propelling the excess water to other parts of the globe, accelerating the real sea level rise in places already at risk. The is where the invisible hand of gravity is at work. The once mighty glaciers have historically exerted a “pull” on nearby waters, bringing the waters closer to Iceland; as they diminish, however, the gravitational pull is reduced and the waters move to other parts of the planet.
