Key takeaways of WMO report
GS Paper - 3 (Environment)
According to a new report, released by the World Meteorological Organization (WMO), Asia is the world’s most disaster-prone region and it experienced 81 weather, climate and water-related disasters in 2022. These events directly affected more than 50 million people with about 5,000 getting killed and economic damage worth $ 36 billion, the report added. Although, in 2021, the continent had been affected by around 100 natural disasters, the extent of these hazards was more prominent in 2022 — the number of people and facilities affected, and economic damage has increased.
What are the key takeaways from the report?
According to the report, while the mean temperature over Asia in 2022 was about 0.72 degree Celsius above the 1991–2020 average, it was about 1.68 degree Celsius above the 1961–1990 average.
This rise in temperatures has had some severe fallouts, including an uptick in the occurrence of extreme weather events.
For instance, droughts ravaged numerous parts of Asia in 2022. China particularly suffered the most as last year, the Yangtze River Basin, located in the country’s southwest, experienced the worst drought in the last six decades.
This not only affected crops and vegetation, as well as the drinking water supply but also caused an economic loss of about $ 7.6 billion.
Many other regions were hit by severe floods and extreme monsoon rainfalls. Pakistan is the most notable example – it received 60 percent of normal total monsoon rainfall within just three weeks of the start of the 2022 monsoon season, and the heavy rains resulted in urban and flash floods, landslides, and glacial lake outburst floods across the country.
More than 33 million people were affected, over 1,730 people died and almost eight million people were displaced, according to the report.
Apart from natural disasters, climate change has exacerbated glaciers melting in Asia due to high temperatures and dry conditions.
Four glaciers in the High Mountain Asia region, centred on the Tibetan Plateau, have recorded significant mass losses, with an accelerating trend since the mid-1990s.
At the same time, these four glaciers show an overall weaker cumulative mass loss than the average for the global reference glaciers during the period 1980–2022.
Even thesea surface temperatures in Asia are getting warmer than ever before. The report pointed out that in the north-western Arabian Sea, the Philippine Sea and the seas east of Japan, the warming rates have exceeded 0.5 degree Celsius per decade since the 1980s. It is about three times faster than the global average surface ocean warming rate.
India in report
In India, heavy rainfalls “lasting from May to September triggered multiple landslides and river overflows and floods, resulting in casualties and damage”.
In total, this flooding resulted in over 2,000 deaths and affected 1.3 million people — the disaster event caused the highest number of casualties of any disaster event in 2022 in India.
The report also said economic loss due to disasters relating to floods exceeded the average for the 2002–2021 period. Pakistan incurred a loss of over $ 15 billion, followed by China, over $ 5 billion, and India, over $ 4.2 billion.
Another extreme weather event that became a mainstay in Asia last year was heat waves.
The report noted that India and Pakistan experienced “abnormally warm conditions” in the pre-monsoon season (March–May), the report mentioned. China, Hong Kong and Japan also saw the mercury rising to record high levels in 2022.

Extreme heat mean for the Mediterranean Sea
GS Paper - 3 (Environment)
Frequent heat waves cause huge damage to underwater ecosystems and researchers expect more of them in the future.
What are the solutions to heat stress?
Extreme heat has plagued the Mediterranean for weeks. Wildfires raged across at least nine countries in the region from Algeria to Greece.
But the soaring temperatures are not only a danger for people and ecosystems on land; they’re also harming marine life.
Without a doubt global climate change is the main reason for the heat waves in the sea. It’s causing the ocean to warm.
Why are high sea temperatures a problem?
In a warming world, marine creatures are in danger of suffocating. Gases like oxygen and carbon dioxide dissolve better at colder temperatures, so that means the warmer the water; the less oxygen is available to breathe.
Conversely, higher temperatures also cause an increase in metabolism, which in turn means animals have to breathe even more than usual). That combination also heightens the risk of death by starvation for marine life.
The rise in temperature accelerates metabolism, and the organisms need more food to maintain this metabolic rate.
Algal blooms are more common in hotter waters too. Such blooms can further deplete oxygen levels and produce toxins harmful for fish, marine mammals and birds, for instance.
What species and ecosystems are worst hit by marine heat waves?
High water temperatures are most harmful for animals living at the bottom of oceans, lakes or rivers.
These benthic species include corals, mussels, sponges, starfish and plants like sea grasses, and are often attached to rock or solid ground. They can’t migrate when it gets too hot.
Scientists observed mass deaths of benthic species along thousands of kilometers of Mediterranean coastline between 2015 and 2019.
Many benthic species are crucial to the marine ecosystem. They filter the water and keep seas, rivers and lakes clean by eating dead organisms.
Some species are an important food source for other creatures or are harvested by humans. Benthics like soft corals, seaweed and seagrasses provide some of the main ocean habitats.
Heat is particularly harmful for Posidonia oceanica or Neptune grass. And the large, slow-growing seagrass is found only in the Mediterranean. Previous heat waves have decimated the species, which is bad news for the climate.
What does extreme heat in the Mediterranean mean for people?
Warming seas are already affecting fishing activities in the area. Fishermen are catching fewer familiar species and instead are finding more invasive fish which they have difficulty selling.
Rabbitfish and lionfish are edible, but other invasive fish aren’t. Some are even poisonous, like the puffer fish.
Habitat loss could also lead to an overall decline in fish populations, while disappearing seagrass means coasts will be more exposed to future storms.
This could also have a knock-on effect for tourism because divers will be less likely to visit an impoverished underwater landscape.

Fukushima nuclear water release
GS Paper - 3 (Nuclear Energy)
Twelve years after the Fukushima nuclear meltdown, Japan is releasing the power plant’s cooling water into the ocean. Japanese officials say it’s safe, but experts are divided. It’s hard to have a purely fact-based discussion about Japan’s Fukushima water release plan. Due to several scandals and a lack of transparency, trust appears to be low in both TEPCO, the company that operated the now-defunct Fukushima-Daiichi nuclear power plant, and the Japanese government, with its close ties to the atomic energy industry.
Fukushima: Why is the water being released into the Pacific Ocean?
Storage tanks holding the cooling water at the ruined facility are full. Japan has had to cool the reactors at the nuclear power plant since they were destroyed during a catastrophic tsunami in 2011.
It takes 170 tons of cooling water per day to keep them cool. In addition, rain and groundwater have been seeping into the site. There are 1,046 storage tanks holding 1,343 million cubic meters of water.
Once the water has been filtered, it is considered safe and sent through a one-kilometer (0.62 mile)-long tunnel before being released into the Pacific Ocean — a process that will take an estimated 30 years to complete. The radioactive waste, meanwhile, will remain on land.
Is Japan allowed to release filtered cooling water into the sea?
Both Japan’s atomic agency and the International Atomic Energy Agency (IAEA) have approved the plan.
The IAEA said Japan had met international safety standards and that “discharges of the treated water would have a negligible radiological impact to people and the environment.
They said it had been common practice for nuclear power plants worldwide to release used cooling water into the ocean for decades routinely.
However, environmental and fishing experts, as well as neighboring states, have accused Japan of downplaying the level of radiation in the cooling water.
They are concerned about far-reaching ocean contamination, potential environmental damage, a fall in fishing revenue and loss of reputation.
How will the water be prepared before it’s released?
Before it’s released into the ocean, the contaminated cooling water and groundwater will be sent through a filter system called the Advanced Liquid Processing System (ALPS).
ALPS can filter 62 different radionuclides — radioactive elements — but can’t filter out the radioactive isotope tritium.
So, TEPCO wants to dilute the water until the concentration of tritium is reduced to about 1,500 Becquerel per liter or less than a fortieth of the national safety standard. A becquerel (Bq) is a unit that measures the rate at which radioactive material emits radiation or how many atoms in the material decay in a given time.
TEPCO says that if the levels of tritium remain too high after filtration, they will repeat the process before releasing the water.
How dangerous is tritium?
Tritium is a form of hydrogen that occurs naturally in Earth’s atmosphere. It is radioactive but far less dangerous than cesium-137 or strontium-90 — both of which are life-threatening.
It emits a weak beta particle that can be stopped by a sheet of plastic or human skin.
It’s a different story if strontium-90 gets into the human body: “Strontium is absorbed by the bones, and once it’s in the crystalline structure of the bones, you can’t get rid of it again.

India, ASEAN agree to deepen strategic ties
GS Paper - 2 (International Relations)
India and 10-nation ASEAN agreed to deepen their comprehensive strategic partnership with concrete actions through practical implementation of the 'Plan of Action' to implement the ASEAN-India partnership for peace, progress and shared prosperity.
More about agreement
In a joint statement on maritime cooperation, it was agreed to support India's connectivity initiatives in the region to ensure seamless connectivity in the Indo-Pacific, besides boosting cooperation in a range of areas including blue economy, space and food security among others.
The two sides agreed to deepen their comprehensive strategic partnership with concrete actions through practical implementation of the 'Plan of Action' to implement the ASEAN-India partnership for peace, progress and shared prosperity.
They reaffirmed the importance of maintaining and promoting peace, stability, maritime safety and security, freedom of navigation and overflight in the region, and other lawful uses of the seas and unimpeded lawful maritime commerce and to promote peaceful resolutions of disputes, in accordance with universally recognised principles of international law, including the 1982 United Nations Convention on the Law of the Sea (UNCLOS).
The two sides agreed to further strengthen ASEAN-India cooperation on maritime safety and security, promote cooperation in a Blue Economy and develop new and renewable energy including marine-based renewable energy, among others.
The Association of Southeast Asian Nations (ASEAN) is considered one of the most influential groupings in the region, and India and several other countries including the US, China, Japan and Australia are its dialogue partners.
ASEAN-India dialogue relations started with the establishment of a sectoral partnership in 1992.
This graduated to a full dialogue partnership in December 1995 and a summit-level partnership in 2002. The ties were elevated to a strategic partnership in 2012.
What is ASEAN?
On 8 August 1967, five leaders – the Foreign Ministers of Indonesia, Malaysia, the Philippines, Singapore and Thailand – came together in Bangkok.
Thailand was brokering some disputes among Malaysia, Indonesia and the Philippines, and it eventually led to the signing of a document.
The five Foreign Ministers who signed it – Adam Malik of Indonesia, Narciso R. Ramos of the Philippines, Tun Abdul Razak of Malaysia, S. Rajaratnam of Singapore, and Thanat Khoman of Thailand – would subsequently be hailed as the Founding Fathers of probably the most successful inter-governmental organisation in the developing world today. And the document that they signed would be known as the ASEAN Declaration.
The ASEAN Declaration signed by the five leaders conveyed the aspiration to further regional cooperation. These were about cooperation in the economic, social, cultural, technical, educational and other fields, and in the promotion of regional peace and stability and adherence to the principles of the United Nations Charter.
Its major pillars that help lay out a blueprint for cooperation are Political-Security Community (APSC), Economic Community (AEC) and Socio-Cultural Community (ASCC).
