New data on forest fires confirms what we’ve long feared: Forest fires are becoming more widespread, burning nearly twice as much tree cover today as they did 20 years ago.
Using data from a new study by researchers at the University of Maryland, we calculated that forest fires now result in 3 million more hectares of tree cover loss per year compared to 2001 — an area roughly the size of Belgium — and accounted for more than a quarter of all tree cover loss over the past 20 years.
Floods, droughts, tropical storms, and heat waves are severely testing the resilience of a region with a lot of vulnerable people.

High temperatures, frequent droughts, torrential rains, and other extreme weather events this summer have throttled Asia, forced industries to shut down, slowed global business, disrupted food supplies, and upended the lives of ordinary people living in some of the world’s most populous countries and densely packed cities.
For months, countries across the Asia-Pacific have been experiencing a mix of heavier rains and higher temperatures, creating unpredictable weather patterns. When the rains aren’t falling a lot—as in Pakistan, where eight monsoon cycles have left thousands of people homeless—they aren’t falling at all, causing energy shortages as droughts have seriously restricted access to hydroelectric power. Record-breaking temperatures in China, for example, have sparked intense wildfires in the country’s center and dried up rivers that cities bank on to power industries and homes.
International efforts, such as the Paris Agreement, aim to reduce greenhouse gas emissions. But experts say countries aren’t doing enough to limit dangerous global warming.
Countries have debated how to combat climate change since the early 1990s. These negotiations have produced several important accords, including the Kyoto Protocol and the Paris Agreement.
Governments generally agree on the science behind climate change but have diverged on who is most responsible and how to set emissions-reduction goals.
Experts say the Paris Agreement is not enough to prevent the global average temperature from rising 1.5°C. When that happens, the world will suffer devastating consequences, such as heat waves and floods.
Over the last several decades, governments have collectively pledged to slow global warming. But despite intensified diplomacy, the world could soon face devastating consequences of climate change.
Through the Kyoto Protocol and the Paris Agreement, countries agreed to reduce greenhouse gas emissions, but the amount of carbon dioxide in the atmosphere keeps rising, heating the Earth at an alarming rate. Scientists warn that if this warming continues unabated, it could bring environmental catastrophe to much of the world, including staggering sea-level rise, record-breaking droughts and floods, and widespread species loss.
Dozens of countries made new commitments during a UN climate conference known as COP26 in November 2021. Still, experts, activists, and citizens remain concerned that these pledges are not ambitious enough.
What are the most important international agreements on climate change?

As the global energy crisis continues to hurt households, businesses and entire economies worldwide, it’s important to separate fact from fiction. There are three narratives in particular that I hear about the current situation that I think are wrong — in some cases dangerously so.
The first is that Moscow is winning the energy battle. Russia is undoubtedly a huge energy supplier and the increases in oil and gas prices triggered by its invasion of Ukraine have resulted in an uptick in its energy income for now. But its short-term revenue gain is more than offset by the loss of both trust and markets that it faces for many years to come. Moscow is doing itself long-term harm by alienating the EU, its biggest customer by far and a strategic partner. Russia’s place in the international energy system is changing fundamentally, and not to its advantage.
Hai ngày sau công bố điểm chuẩn, Hoàng Thu Giang (một nữ sinh tại Thái Bình) vẫn chưa thể vượt qua cú sốc “đầu đời” rằng mình đã trượt đại học dù em được 25 điểm và đăng ký 8 nguyện vọng.
Điểm cao vẫn trượt đại học
Nhận kết quả điểm thi tốt nghiệp THPT, Hoàng Thu Giang khá vui mừng khi em được 25 điểm tổ hợp A00 (Toán, Lí, Hoá). Với mức điểm này, Giang tự tin đăng ký vào ngành Công nghệ thông tin và ngành Kinh tế. Em sắp xếp nguyện vọng ưu tiên hai nhóm ngành này có mức điểm tương đương điểm của mình năm trước, sau đó thêm nguyện vọng vào một số ngành “chống trượt” với mức điểm chuẩn năm ngoái thấp hơn điểm của Giang vài điểm.
“Sau khi nghiên cứu điểm chuẩn của năm 2020, em khá tự tin khi đăng ký nguyện vọng năm nay ở tổ hợp A00 vào các ngành Kinh tế, Công nghệ thông tin. Thế nhưng sau khi xem điểm chuẩn năm 2020, em mới tá hỏa vì cả 8 nguyện vọng của em đều trượt hết. Ngay cả ngành “chống trượt” cũng tăng gần 3 điểm so với năm ngoái”, Giang chia sẻ.
Giang kể thêm: “Em không thể tin nổi vào mắt mình khi chỉ thiếu 0,25 điểm để đỗ nguyện vọng số 8, còn nguyện vọng số 7 vào Quản trị Kinh doanh của Học viện Chính sách và Phát triển cũng tăng 3 điểm nên em cũng thiếu 0,5 điểm”, Giang nói.
Vietnam’s coal imports are forecast to rise to meet domestic production demand, according to a draft strategy for developing the coal industry in Vietnam recently introduced by the Ministry of Industry and Trade (MoIT).
Hanoi (VNA) – Vietnam’s coal imports are forecast to rise to meet domestic production demand, according to a draft strategy for developing the coal industry in Vietnam recently introduced by the Ministry of Industry and Trade (MoIT).
Accordingly, Vietnam will import about 50-83 million tonnes of coal per year during the period from 2025 to 2035, with the volume gradually falling to about 32-35 million tonnes by 2045.
The data from the MoIT shows domestic coal consumption increased rapidly from 27.8 million tonnes in 2011 to 38.77 million tonnes in 2015, and about 53.52 million tonnes in 2021.
The volume of coal consumed at present has more than doubled compared to 2011, mainly for electricity production.
The demand for primary energy, including coal, will continue to increase, possibly peaking in the 2030-2035 period, the ministry said.
Vietnam’s coal demand will be around 94-97 million tonnes in 2025, and peak at 125-127 million tonnes in 2030, mainly due to the increase in demand for power generation, and the cement, metallurgy and chemical industries.
The ministry also predicted that the demand for energy after 2040 will decline due to the energy transition process to meet emission reduction targets.
The paper provides a wealth of data about the current state of the nuclear industry and the potential for its growth over the next ten to twenty years, while also considering important questions about the geopolitical dimensions which underpin the relationships between the exporters and importers of nuclear technology and the ties, such as financing and provision of services in the nuclear energy value chain, which bind them over multiple decades

On August 14 1912, a small New Zealand newspaper published a short article announcing global coal usage was affecting our planet’s temperature.
This piece from 110 years ago is now famous, shared across the internet this time every year as one of the first pieces of climate science in the media (even though it was actually a reprint of a piece published in a New South Wales mining journal a month earlier).
So how did it come about? And why has it taken so long for the warnings in the article to be heard – and acted on?
The fundamental science has been understood for a long time
American scientist and women’s rights campaigner Eunice Foote is now widely credited as being the first person to demonstrate the greenhouse effect back in 1856, several years before United Kingdom researcher John Tyndall published similar results.
Her rudimentary experiments showed carbon dioxide and water vapour can absorb heat, which, scaled up, can affect the temperature of the earth. We’ve therefore known about the relationship between greenhouse gases and Earth’s temperature for at least 150 years.
when it comes to the Paris Agreement and climate action; namely that when individuals change their behaviour by consuming differently they can drive industries to change, as those industries are then caught between a ‘greening’ consumer demand and international and governmental policies focusing on climate action.
Back in the 1980s, everyone was talking about the hole in the ozone layer, so what happened, and what can the international agreement to ban CFCs teach us about the importance of multilateral cooperation when it comes to climate action?
What exactly is the ozone layer?
The ozone layer is the part of the Earth’s atmosphere that protects the planet from ultraviolet radiation. It’s found in the Stratosphere which is around 10-50km above the surface of the earth. Think of it as a layer of sunscreen that protects us from all manner of harmful rays. Without it, life on Earth would be extremely unpleasant.
The Earth is approximately 1.1℃ warmer than it was at the start of the industrial revolution. That warming has not been uniform, with some regions warming at a far greater pace. One such region is the Arctic.
A new study shows that the Arctic has warmed nearly four times faster than the rest of the world over the past 43 years. This means the Arctic is on average around 3℃ warmer than it was in 1980.
This is alarming, because the Arctic contains sensitive and delicately balanced climate components that, if pushed too hard, will respond with global consequences.
Why is the Arctic warming so much faster?
A large part of the explanation relates to sea ice. This is a thin layer (typically one metre to five metres thick) of sea water that freezes in winter and partially melts in the summer.
The sea ice is covered in a bright layer of snow which reflects around 85% of incoming solar radiation back out to space. The opposite occurs in the open ocean. As the darkest natural surface on the planet, the ocean absorbs 90% of solar radiation.
When covered with sea ice, the Arctic Ocean acts like a large reflective blanket, reducing the absorption of solar radiation. As the sea ice melts, absorption rates increase, resulting in a positive feedback loop where the rapid pace of ocean warming further amplifies sea ice melt, contributing to even faster ocean warming.
With climate change influencing more than 1,000 transmission pathways like those and climate hazards increasingly globally, we concluded that expecting societies to successfully adapt to all of them isn’t a realistic option. The world will need to reduce the greenhouse gas emissions that are driving climate change to reduce these risks.
TTCT – Khi người tiêu dùng rên xiết bởi đồng tiền mất giá, lãi bán hàng không đủ mua xăng dầu, hay mùa đông tới châu Âu có lẽ phải hạ lò sưởi xuống 18 độ C – thì chiến sự ở Ukraine là lời giải thích quá vội vã và quá dễ dãi. Về lâu dài, biến đổi khí hậu mới là nguyên nhân chính.

Các nghiên cứu trước đây đã chỉ ra mối liên hệ giữa thời tiết khắc nghiệt và khủng hoảng kinh tế, nhưng chỉ tập trung vào các nước đang phát triển, tình cờ cũng là những quốc gia bị lũ lụt, bão và hạn hán thường xuyên và nghiêm trọng hơn nhiều so với phương Tây. Nói cách khác, người ta đã cố tình lờ đi một điểm yếu của phương Tây, vốn vẫn luôn bị ảnh hưởng bởi biến đổi khí hậu, nay chỉ lộ rõ hơn vì chiến sự Ukraine.
Green water – the rainwater available to plants in the soil – is indispensable for life on and below the land. But in a new study, we found that widespread pressure on this resource has crossed a critical limit.
The planetary boundaries framework – a concept that scientists first discussed in 2009 – identified nine processes that have remained remarkably steady in the Earth system over the last 11,700 years. These include a relatively stable global climate and an intact biosphere that have allowed civilisations based on agriculture to thrive. Researchers proposed that each of these processes has a boundary that, once crossed, puts the Earth system, or substantial components of it, at risk of upset.
Vietnam is increasingly seeing its development affected by climate change and now faces critical questions about how to respond. The Vietnam Country Climate and Development Report proposes that Vietnam shift its development paradigm by incorporating two critical pathways – resilient pathway and decarbonizing pathway – that will help the country balance its development goals with increasing climate risks.
After more than two decades of steady growth, Vietnam has set an ambitious goal of reaching high-income status by 2045. It has been recognized in the 2021-2030 Socioeconomic Development Strategy that the country’s economic transformation will greatly depend on better management of natural capital – the extensive stocks of agricultural, forest, and mineral resources that have helped drive development.
