In the area you have selected (Vietnam) tsunami hazard is classified as medium according to the information that is currently available. This means that there is more than a 10% chance of a potentially-damaging tsunami occurring in the next 50 years. Based on this information, the impact of tsunami should be considered in different phases of the project for any activities located near the coast. Project planning decisions, project design, and construction methods should take into account the level tsunami hazard. Further detailed information should be obtained to adequately account for the level of hazard.

Climate change impact: The areas at risk of tsunami will increase as global mean sea level rises. According to the IPCC (2013), global mean sea level rise depends on a variety of factors, and estimates for 2100 range from ~20 cm to nearly 1 m. However, regional changes in sea level are difficult to predict. Projects in low-lying coastal areas such as deltas, or in island states should be designed to be robust to projected increases in global sea level.

Ten years after the landmark Paris Agreement, the world is still trying to solve two crises as if they were separate: climate change and economic development. That’s a dangerous illusion. Climate progress cannot succeed if billions of people remain in poverty, without electricity, stable food systems, or the means to build better lives. And development, if it ignores climate risk, is little more than a short-term fix that will collapse under the weight of future disasters.
I saw this tension firsthand at COP30 in Belém, Brazil, the annual UN climate summit. The energy there was unmistakable—a mixture of urgency and frustration. Delegates from across Africa reminded the world that promises made in Paris have not been kept. Wealthy nations pledged to support developing countries as they cut emissions and adapted to rising temperatures. Yet, a decade later, those commitments remain largely unfulfilled.
At COP29 in Baku last year, developed countries agreed to mobilize at least $300 billion annually by 2035 for developing countries’ climate action, part of a broader aspirational target of $1.3 trillion per year. While this represents a tripling of the previous $100 billion goal, representatives from developing countries remain skeptical. More fundamentally, the $300 billion commitment falls far short of actual needs. The Independent High-Level Expert Group on Climate Finance estimates that developing countries (excluding China) need approximately $2.7 trillion annually by 2030 to meet climate and nature-related goals. The gap between promise and reality remains vast—and widening
But money is only part of the problem. Even when funding arrives, it often misses the mark. A new analysis by the Clean Air Task Force looked at 52 African countries’ climate and development plans. It found that the two rarely intersect. Climate strategies focus on emissions and energy transitions, while national development plans emphasize job creation and economic growth—but without embedding climate targets. The result is a patchwork of policies that fail to deliver either lasting prosperity or real emissions cuts.
As Bill Gates noted in a recent memo, global climate policy increasingly risks sidelining development altogether. Today, more than 600 million Africans lack access to electricity, while 900 million do not have clean cooking technologies—conditions that undermine productivity, constrain public services, and contribute to preventable deaths.
Crucially, this should not be understood as an either/or dilemma. Wealthy nations already recognize that decarbonization must go hand in hand with economic growth to be politically viable at home. The same is true globally. Emerging and developing economies cannot be expected to choose between climate progress and economic progress. Insisting on a tradeoff between the two as a trade-off is both unrealistic and unjust.
When climate and development are treated as separate silos, everyone loses. Fragmented planning leads to inefficient allocation of scarce resources, missed opportunities for infrastructure investments with broad benefits, and policies that fail to produce either meaningful emissions reductions or durable socio-economic progress. Importantly, this is not a challenge restricted to Africa but a blind spot in international climate governance. Even wealthy countries are discovering that climate action divorced from economic realities is politically unsustainable. When climate action appears to threaten economic growth, job creation, or living standards, political support erodes quickly.
As negotiations in Belém draw to a close, one truth should be clear: climate and development are not competing agendas—they are the same story. Sustainable development is the foundation of lasting climate progress. And climate resilience is the only path to enduring prosperity. Any strategy that treats them separately is doomed to fail.
Development without climate action is a short-term fix. And climate action without development is an empty promise.
Global Forest Watch’s (GFW) deforestation alerts provide information about loss of tree cover in near-real-time, making them a critical tool for those working to combat deforestation. Existing alerts on GFW have been used to help Indigenous and local communities protect their forests, halt and prosecute environmental crimes and protect threatened wildlife.
However, in the past, alerts only let users know there’s been a disturbance without identifying a cause, other than a few limited classes such as fires.
Now, new drivers of deforestation alerts data is available on GFW that shows the causes of alerts across the tropics. This innovative data set uses an AI method to assign drivers to GFW’s integrated deforestation alerts in the three major forested regions in the tropics, allowing users to see what’s driving loss in near-real-time in these regions for the first time.
Critically, this information helps users distinguish between tree cover loss from natural and human causes, enabling more targeted action from those managing forests and reducing the need for costly field visits. Further, the data also provides more rapid information to estimate ecological impacts and supports better understanding of carbon emissions related to forest disturbances.
Almost exactly 10 years ago, a remarkable thing happened in a conference hall on the outskirts of Paris: After years of bitter negotiations, the leaders of nearly every country agreed to try to slow down global warming in an effort to head off its most devastating effects.
The core idea was that countries would set their own targets to reduce their climate pollution in ways that made sense for them. Rich, industrialized nations were expected to go fastest and to help lower-income countries pay for the changes they needed to cope with climate hazards.
So, has anything changed over those 10 years? Actually, yes. Quite a bit, for the better and the worse. For one thing, every country remains committed to the Paris Agreement, except one. That’s the United States.
Forests directly cool the planet, like natural evaporative air conditioners. So what happens when you cut them down?
In tropical countries such as Indonesia, Brazil and the Congo, rapid deforestation may have accounted for up to 75% of the observed surface warming between 1950 and 2010. Our new research took a closer look at this phenomenon.
Using satellite data over Indonesia, Malaysia and Papua New Guinea, we found deforestation can heat a local area by as much as 4.5°C, and can even raise temperatures in undisturbed forests up to 6km away.
More than 40% of the world’s population live in the tropics and, under climate change, rising heat and humidity could push them into lethal conditions. Keeping forests intact is vital to protect those who live in and around them as the planet warms.
The five Mekong countries lost nearly 1 million hectares (2.5 million acres) of tree cover in 2024, with nearly a quarter of which was primary forest, and more than 30% of losses occurring inside protected areas.
Cambodia and Laos saw some of the highest levels of loss inside protected areas, driven by logging, plantations and hydropower projects, though both countries recorded slight declines from 2023.
In Myanmar, conflict has complicated forest governance, with mining and displacement contributing to losses, though overall deforestation fell slightly compared to the previous year.
Thailand and Vietnam bucked the regional trend, with relatively low forest losses in protected areas, supported by logging bans, reforestation initiatives, and stricter law enforcement.

BANGKOK — The Mekong countries of Cambodia, Laos, Myanmar, Thailand and Vietnam lost a combined area of tree cover of nearly a million hectares in 2024, or an area almost the size of Lebanon. That’s according to Mongabay’s analysis* of satellite data published by the Global Land Analysis and Discovery (GLAD) laboratory at the University of Maryland, in partnership with Global Forest Watch (GFW).
GFW data show 991,801 hectares (2.45 million acres) of tree cover were lost in 2024, including nearly 220,000 hectares (544,000 acres) of primary forest, across the five Mekong countries. More than 30% of tree cover loss recorded in 2024 occurred inside protected areas, although across the region, the rate of deforestation — both within protected areas and outside of them — slowed slightly from 2023. Despite this, the drivers of deforestation vary somewhat from country to country, and last year’s losses still reflect a grim trajectory for forests in the Mekong region.
The economies of almost all Mekong countries are heavily reliant on agriculture, with forests cleared for both agribusiness-run plantations or subsistence farming plots. But research indicates the conversion of forest to croplands has resulted in increasingly unpredictable weather patterns and subsequently poorer agricultural yields.
This ARSET training covers general approaches to apply satellite remote sensing data when studying or forecasting climate-sensitive infectious diseases.
Description
Climate-sensitive vector-borne diseases such as malaria impact millions of people each year, causing more than 700,000 deaths annually, according to the World Health Organization (WHO). Satellite remote sensing data can provide valuable insights for monitoring conditions which support disease vectors. In this training, participants will learn the basic principles of how satellite remote sensing data can be applied to track climate-sensitive vector-borne disease outbreaks and provide early warnings for potential outbreaks. Participants will learn about general approaches to apply satellite remote sensing data when studying or forecasting climate-sensitive infectious diseases. These will be illustrated with a case study example in the forecasting of malaria. Participants will also become familiar with some of the common, freely available NASA remote sensing datasets used in these applications, as well as where and how to access them and how to decide which datasets are fit for their purpose.

A groundbreaking new report, “Resilience, Readiness, and Response,” from Project CASA (Climate and Security Action through Civil-Military Cooperation in Climate-Related Emergencies) highlights the increasing and essential role of national militaries in addressing the escalating global climate crisis.
The report is the result of a comprehensive two-year study which provides the first cross-national dataset on military involvement in climate disasters. Edited by Ronald A. Kingham and Dr. Ashley McIlvain Moran and published by the Environment & Development Resource Centre (EDRC), the report serves as both a critical resource and a call to action for policymakers and practitioners grappling with climate-worsened disasters.
New research analyzing more than 3,000 tropical forest sites reveals that areas with fewer seed-dispersing animals store up to four times less carbon than forests with healthy wildlife populations.
The study found that 81% of tropical trees rely on animals to disperse their seeds, establishing an ancient partnership now threatened by human activities such as deforestation, road construction, and hunting.
Researchers mapped global “seed dispersal disruption” and found it explains a 57% reduction in carbon storage potential across proposed forest restoration areas.

Published On 15 Aug 2025
Global talks to develop a landmark treaty to tackle plastic pollution have once again failed to reach an agreement, despite efforts late into the night to strike a deal.
Delegates at a closing meeting of the Intergovernmental Negotiating Committee (INC) in Geneva on Friday spoke of their dismay at the failure to break a deadlock at the sixth round of talks in under three years, as countries remained deeply divided over the scope of any treaty.
“South Africa is disappointed that it was not possible for this session to agree a legally binding treaty and positions remain far apart,” its delegate told a closing meeting.
Cuba’s delegate said that negotiators had “missed a historic opportunity but we have to keep going and act urgently”, the AFP news agency reported.
Some fear the world is fast approaching temperature levels where professional risk managers will no longer be able to offer cover for financial services.
Günther Thallinger, a board member at Allianz, one of the world’s biggest insurers, says the climate crisis could make adaptation economically unviable.
Zurich Insurance Group, meanwhile, said alongside a recent research paper assessing climate resilience that the outlook looks “alarmingly bleak.”

Top insurers fear the climate crisis could soon outpace industry solutions, effectively threatening to make entire regions around the world uninsurable.
Günther Thallinger, a board member at Allianz, one of the world’s biggest insurers, recently outlined how the world is fast approaching temperature levels where insurers will no longer be able to offer cover for financial services, such as mortgages and investments.
In practice, this scenario implies some may face difficulty being able to afford home insurance cover, which is typically a prerequisite for getting a mortgage.
In a LinkedIn post published in late March, Thallinger made the case for rapid decarbonization, pointing out that entire asset classes were “degrading in real time” as extreme weather events take their toll. Perhaps most strikingly of all, he warned the worsening climate crisis appears to be on track to destroy capitalism.
Insurance, which is regarded as the invisible lubricant of the global economy, has a unique role to play in addressing climate-related risks. As professional risk managers, insurers routinely allow investors to take on calculated risks, protecting individuals and businesses against financial losses.
Thallinger, who is responsible for investment management and sustainability at Allianz, told CNBC that approximately two-thirds of economic losses from natural catastrophes are currently uninsured, indicating a “major societal problem.”
As global supply chains pivot towards low-emissions production, Australia will need to lead, or risk being left behind. The country’s challenge is not a lack of technology, capital, or ambition. It’s a gap in policy architecture. Without bankable demand, Australia’s most promising clean commodity projects – green iron, sustainable aviation fuel, and clean ammonia – remain stuck at the starting line.
To meet that challenge, we propose a new demand-side policy model: the Clean Commodities Trading Initiative (CCTI) – a flagship example of green energy statecraft. At its heart is a new tool for national transformation: Clean Commodity Credits that reward innovation and emissions savings.
A market-friendly mechanism to kickstart large-scale clean production.
Green energy statecraft is a strategic approach to governance that uses the clean energy transition to simultaneously advance a nation’s economic, environmental, social, and geostrategic goals. Unlike conventional industry policy, which focuses on domestic market corrections, statecraft treats clean energy as key to national security and prosperity – used to build alliances, secure supply chains, boost productivity, and shape global rules.
The European Union, China, Japan, and South Korea are all pursuing variations of green energy statecraft. Australia must do the same – on its own terms, with tools suited to its advantages, institutions, and budget.

More than a third of the population of Tuvalu has applied to move to Australia, under a landmark visa scheme designed to help people escape rising sea levels.
The island nation – roughly halfway between Hawaii and Australia – is home to about 10,000 people, according to the latest government statistics, living across a clutch of tiny islets and atolls in the South Pacific.
On June 16, Australia opened a roughly one-month application window for what it says is a one-of-a-kind visa offering necessitated by climate change. Under the new scheme, Australia will accept 280 visa winners from a random ballot between July and January 2026. The Tuvaluans will get permanent residency on arrival in Australia, with the right to work and access public healthcare and education.
More than 4,000 people have applied under the scheme, according to official figures seen by CNN.
“The opening of the Falepili Mobility Pathway delivers on our shared vision for mobility with dignity, by providing Tuvaluans the opportunity to live, study and work in Australia as climate impacts worsen,” Australian Foreign Minister Penny Wong said in a statement.
CNN has reached out to the Tuvalu government.
According to Tuvalu’s Prime Minister Feleti Teo, more than half of Tuvalu will be regularly inundated by tidal surges by 2050. By 2100, 90% of his nation will be regularly under water, he says.
Fongafale, the nation’s capital, is the largest and most populated islet in Tuvalu’s main atoll, Funafuti. It has a runway-like strip of land just 65 feet (20 meters) wide in some places.
“You can put yourself in my situation, as the prime minister of Tuvalu, contemplating development, contemplating services for the basic needs of our people, and at the same time being presented with a very confronting and disturbing forecast,” Teo told the United Nations Oceans Conference this month in Nice, France.
At the Third UN Ocean Conference in Nice, the “catch of the day” wasn’t a seabass or a red mullet – it was a figure: 35 per cent. That’s the share of global fish stocks now being harvested unsustainably, according to a new UN report released Wednesday.
As yachts bobbed gently and delegates streamed by in a rising tide of lanyards and iPads at Port Lympia, Nice’s historic harbor, that statistic sent a ripple through the conference’s third day – a stark reminder that the world’s oceans are under growing pressure from overfishing, climate change and unsustainable management.
World leaders have renewed calls for a global moratorium on deep-sea mining at the 2025 U.N. Ocean Conference (UNOC) in Nice, France, as the U.S. moves to mine the deep sea in international waters under its own controversial authority.
Four additional countries have joined the coalition of nations calling for a moratorium, precautionary pause, or ban on deep-sea mining, bringing the total number to 37.
The U.S., which did not have an official delegation at UNOC, is pushing forward with its plans to mine in international waters — a decision that has drawn criticism from the international community.
