Antarctica glacier melting means terrible news for global sea level rise
The Thwaites Glacier in Antarctica, also known as the Doomsday Glacier, is melting in unexpected ways that could lead to its rapid collapse, a new study has revealed.
Sometimes called the Doomsday Glacier as its collapse could destabilize other glaciers in West Antarctica and lead to a potential 3 meter rise in sea level, scientists.
Two teams of researchers have used an underwater robot and drilled deep holes into the Florida-sized Thwaites Glacier to study its melting patterns in unprecedented detail, Space.com reported.
The researchers from the International Thwaites Glacier Collaboration discovered that while the overall melting of ice is slower than expected, melting in cracks and crevasses and other vulnerable areas is proceeding much more rapidly.
"Our results are a surprise but the glacier is still in trouble," British Antarctic Survey oceanographer and research team member Peter Davis, said in a statement.
Thwaites Glacier is located in West Antarctica and covers 192,000 square kilometers. One part of the glacier juts out into the ocean and holds back the rest of the ice-mass that lies on bedrock, thus preventing it from slipping from the land to the sea.
Because the Thwaites Glacier slopes down towards the sea, it is particularly susceptible to climate and ocean temperature changes that could lead to rapid and irreversible ice loss. The collapse of Thwaites would cause seawater levels and destabilize neighboring glaciers.
The new data provides a clearer picture of the changes taking place under Thwaites, revealing that ice in cracks across the glacier is melting quickly. Melting in cracks and crevasses is potentially dangerous because as water funnels through them, heat and salt can be transferred into the ice. This can result in the widening of these crevasses, causing large rifts in the ice shelf. Cracks and crevasses weren't the only area of the shelf experiencing rapid melting, however.
The scientists also found that melting across the bottom of the ice shelf has created a staircase-like formation. In these staircase-shaped regions, called terraces, the ice of Thwaites is also melting rapidly.
The melting of ice in these terraces, cracks, and crevasses may become major factors in the loss of ice from Thwaites in the future, especially as major rifts progress across the ice shelf. This means these features may become the primary trigger for ice shelf collapse at Thwaites.

Kandahar’s Takhtapul district hit hard by ongoing drought
Afghanistan has experienced three consecutive years of drought, including the most devastating drought in 30 years in 2021 and 2022.
Residents of Takhtapul district of Afghanistan’s Kandahar province say they are struggling to survive amid an ongoing drought that has devastated their crops.
This rural community mainly relies on agriculture to survive but climate change has virtually ended any hopes of farming.
Afghanistan has experienced three consecutive years of drought, including the most devastating drought in 30 years in 2021 and 2022.
Climate experts predict that by 2050, 90% of its territory will be affected by drought.
Afghanistan is one of the ten countries most vulnerable to climate change. It's also ranked fourth in overall disaster risk.
Takhtapul residents have spoken out about their plight and said they have sustained extensive losses due to the drought
They said in the past they had made a living off farming, but now due to the severe lack of water, their land has become barren.
They also said this is forcing their youth and younger generation to find work in other provinces or outside the country.
Abdullah, a resident of Takhtapul district of Kandahar, said: "Our youths have gone to Pakistan and other provinces in search of work due to unemployment and drought. There they have wheelbarrows [for day labourer work] or they do other jobs."
On the other hand, local officials say that they are trying to reduce unemployment by launching development projects in this district.
Along with droughts and lack of work for young people, the breakdown of roads, lack of health centers and lack of suitable places for education are among the problems that the residents of this district want to solve.

EU pledges €15 million to WFP to help mitigate climate crisis impact on Afghans
The United Nations World Food Programme (WFP) has welcomed a €15 million (US$15.8 million) contribution from the European Union (EU) for its climate related activities in Afghanistan.
According to a statement issued by the EU on Thursday, this contribution will help local communities prepare for natural disasters and face the devastating effects of climate change, and support farmers for more productive and sustainable agriculture.
So far this year, more than 160,000 people have been affected by flooding in Afghanistan. Floods have destroyed almost 20,000 homes, and thousands of hectares of agricultural land.
“The European Union is committed to assisting the people of Afghanistan in adapting to climate change, which is severely threatening food security and livelihoods notably of rural communities, said the EU Chargée d’Affaires to in Afghanistan, Veronika Boskovic Pohar.
“Climate-related shocks also exacerbate host communities’ capacity to support internally displaced people and returnees from neighboring countries, and they discourage farmers in poppy-cultivating areas from sustainably shifting to licit crops.
“This latest contribution increases the European Union’s steady support to WFP’s resilience programme in Afghanistan to a total EUR 85.1 million since 2022”, she said.
Harald Mannhardt, WFP Deputy Country Director in Afghanistan, said: “This latest funding from the European Union comes at a critical moment as WFP earlier this year was forced to halt projects across the country due to a massive funding shortfall.”
Afghanistan is currently ranked seventh on the Notre Dame Global Adaptation Index of countries most vulnerable and least prepared to adapt to climate change.

Malaysia records six months of rain in just five days
One of the worst hit areas was Kelantan which recorded 1,442mm of rain between November 26 and 30
Six months worth of Malaysia’s average annual rainfall fell within five days across the east coast of the country last week, Prime Minister Datuk Seri Anwar Ibrahim said early Tuesday.
One of the worst hit areas was Kelantan which recorded 1,442mm of rain between November 26 and 30.
Ibrahim said the high rainfall led to flooding that forced a large number of people in Kelantan and Terengganu to be evacuated.
The recorded rainfall at Irrigation and Drainage Department stations in Tanah Merah and Tumpat, exceeded 1,167mm in just five days.
“According to the Malaysian Meteorological Department (MetMalaysia), the reading (in Kelantan) was at 1,442mm, an extraordinarily high level of rainfall. In Terengganu, MetMalaysia’s Besut station recorded 1,761mm of rain during the same period.
“Overall, the (average) rainfall was 1,349mm, far beyond our expectations,” Anwar told the Dewan Rakyat (Parliament) on Tuesday.
He also said the government is preparing for the forecast monsoon surge as announced by MetMalaysia, expected to start after Dec 8.
By Tuesday, some residents in the town of Tumpat were returning to submerged homes and shops as deadly floodwaters eased in some areas.
People who returned to their homes found many had collapsed, with parts of walls, roofs and broken furniture lying scattered in pools of water.
Muhamad Alim, a 56-year-old shopkeeper whose food store was inundated, recalled fast-rising waters in his home and his grandchildren crying as the flood surged on Saturday night.
"Electricity was cut off, and there was no water supply. So, we were stuck, sitting there as if we were in the middle of the sea, surrounded by water," he told Reuters.
"You could hear the sound of water rushing cutting through the silence of the night."
Six people have died in Malaysia and more than 150,000 were evacuated during the height of the floods last week, government data showed.
In Thailand, the death toll is 25, and more than 300,000 households were still affected, the interior ministry said.
The number of people in temporary shelters in Malaysia fell to just under 95,000 on Tuesday morning, though the authorities remain on guard for a second wave of floods this week.
Malaysia's Meteorological Department expects a wind convergence to begin on Tuesday, potentially bringing heavy showers, with a monsoon surge to follow on Dec. 8.
In Thailand, the Meteorological Department warned people in the south of the country to beware of heavy to very heavy rains and possible flash flooding and overflows from Dec. 3-5.
