HUMBOLDT GLACIER -
GEOGRAPHY
News: How did Venezuela’s Humboldt
glacier shrink to an ice field?
What's in the news?
●
The International Cryosphere Climate Initiative
(ICCI) has reported that Venezuela’s last glacier Humboldt or La Corona in the Andes has become too small to be
qualified as a glacier.
Humboldt Glacier:
●
It is also known as Sermersooq Glacier, which is one of the major glaciers in northern Greenland. It borders the Kane
Basin in North West Greenland.
●
It holds the distinction of being the widest
tidewater glacier in the Northern Hemisphere.
●
The standard size for an area to be considered a
glacier is approximately 10 hectares.
●
The Humboldt
glacier in Venezuela has diminished to less than 2 hectares in size,
prompting a downgrade in its classification from a glacier to an ice field.
Current State of the
Glacier:
●
Venezuela has once hosted 6 glaciers in the Sierra Nevada de Mérida, now it
has none.
●
The last Humboldt glacier melted faster than
expected and has been reclassified as an ice field due to its reduced size.
Causes of Melting:
1. Climate Impact:
●
Experts attribute the accelerated melting to rising
temperatures driven by climate change and the recent El Niño phenomenon, which
exacerbates the warmth.
2. Lack of Monitoring:
●
Political turmoil in Venezuela has hindered
consistent scientific monitoring of the glacier.
●
The Venezuelan government attempted to slow the
melting by installing a thermal blanket over the glacier, but experts consider
this measure ineffective.

Global Context and
Future Outlook:
●
The International
Cryosphere Climate Initiative (ICCI) noted that Venezuela is likely the
first modern nation to lose all its glaciers. Other countries at risk of
becoming glacier-free include Indonesia, Mexico, and Slovenia.
●
The high-mountain region of Asia has also seen
significant glacier loss due to record high temperatures and dry conditions.
●
Experts warn that glacier melting may be
irreversible, stressing the importance of protective measures to preserve
remaining glaciers.
International Cryosphere
Climate Initiative:
●
It was established in 2009 following the COP-15 summit in Copenhagen.
●
ICCI is a pivotal network aimed at cryosphere preservation.
Mission:
●
The initiative involves a collaboration of senior
policy experts and researchers who work closely with governments and various
organizations.
Goal:
●
The goal is to develop and implement strategies
that help preserve as much of Earth’s cryosphere as possible.
Focus Areas:
●
ICCI’s efforts concentrate on the unique climate
dynamics affecting three key cryosphere
regions - the Arctic, the Antarctic, and high mountain areas.
●
The organization plays a critical role in adding
urgency to global climate change efforts, particularly concerning CO2 and other
greenhouse gases.
● It emphasizes the swift and profound global implications of cryosphere warming.
