NASA REVEALS GLOBAL SEA LEVELS ROSE BY UNEXEPECTED HIGHER LEVELS : HUNDREDS OF CITIES MAY BE OVERWHELMED

DAILY MAIL : NASA ...GLOBAL SEA LEVEL RISE UNEXPECTEDLY HIGH AMOUNT 

The rise we saw in 2024 was higher than we expected,' said Josh Willis, a sea level researcher at NASA's Jet Propulsion Laboratory in Southern California.

'Every year is a little bit different, but what's clear is that the ocean continues to rise, and the rate of rise is getting faster and faster.'

Since 1993, global sea levels have risen by a staggering 3.97-inches (10.1cm).

And if they continue to climb at this rate, hundreds of densely populated cities around the world could be plunged underwater. Excerpt: According to NASA, this 'unexpected' increase was due to an unusual amount of ocean warming, combined with meltwater from land-based ice such as glaciers.

ICEBERG THE SIZE OF CHICAGO LET GO FROM ANTARTICA

NASA EARTH OBSERVATORY - ICEBERG SPEEDS AWAY

Excerpt: Named A-84 by the U.S. National Ice Center, the berg measures about 30 kilometers (19 miles) long and 17 kilometers (11 miles) wide. It has an area approaching the size of Chicago, Illinois.

Iceberg calving is a normal occurrence  for ice shelves. However, factors such as warming air and water along with decreasing protective sea ice can accelerate calving and lead to collapse, as has happened to several ice shelves along the Antarctic Peninsula.

Observations made by explorers beginning in the early 1940s, and later by remote sensing, show that the George VI has been losing shelf ice. For now, the retreat has been gradual, aided by the stability provided by its unique location, sandwiched between the Antarctic Peninsula and Alexander Island. *** Siren here! As we know, iceberg melt can raise the sea level. Other, larger bergs have broken off and gone to sea...

NASA on GLOBAL CLIMATE CHANGE : WHAT'S A ZETTAJOULES?

CLIMATE NASA on VITAL SIGNS OF OCEAN WARMING 

Excerpt: Heat stored in the ocean causes its water to expand, which is responsbile for one-third to one-half of global sea level rise. Most of the added energy is stored at the surface, at a depth of zero to 700 meters. The last 10 years were the ocean's warmest decade since at least the 1800's.
