Climate Critical Point is Approach
Global warming is rapidly transforming earth's environment

Climate critical point effect
The Arctic sea ice area has decreased by 40% compared to the 1980s, leading to accelerated thawing of the Siberian permafrost and releasing methane equivalent to four years of global fossil fuel carbon emissions. 17% of the Amazon rainforest has degraded into grasslands, and its carbon sequestration capacity has decreased by 34% compared to 20 years ago. According to data from the Manaus monitoring station in Brazil, the carbon emissions from forest fires during the dry season in 2023 will exceed the total annual emissions of the European Union. The United Nations Environment Programme (UNEP) has warned that 9 out of 15 key climate tipping points on Earth have been activated.
Ecological economic dual disaster
Pakistan's catastrophic floods in 2022 submerged one-third of its territory, causing 1700 deaths and $30 billion in losses, equivalent to 10% of the country's annual GDP. The Horn of Africa is experiencing its worst drought in 40 years, with 28 million people falling into famine and Somalia's child malnutrition rate soaring to 57%. Southeast Asian fisheries are facing collapse due to seawater acidification, and soil salinization in the Mekong Delta of Vietnam has engulfed 400000 hectares of rice fields, forcing 2 million farmers to switch to odd jobs. The World Meteorological Organization (WMO) estimates that extreme weather will directly cause global economic losses of $380 billion in 2023, an increase of 147% compared to the average of the past 20 years.

Human ecology reconstructed by climate
In Borisal, Bangladesh, 65 year old farmer Kasim is harvesting semi withered rice in waist deep floods: 'Ten years ago, this time of year, we should have prepared to sow, but now even the location of our ancestors' graves has been swallowed up by the sea.'. In Nuuk, Greenland, the Inuit hunter Julius family's millennium old dog sled has disappeared, traditional hunting routes have disappeared due to glacier retreat, and snow houses have been replaced by Danish imported container houses. Phoenix, USA experience 31 consecutive days of temperatures exceeding 43 ℃ in 2023, with the lowest nighttime temperature still reaching 38 ℃. Elderly residents in slums are struggling to choose between air conditioning debt and heatstroke.
Climate migration and civilization conflict
According to the United Nations High Commissioner for Refugees (UNHCR), the number of people displaced by climate disasters in the past five years has reached 210 million, exceeding the total number of war refugees. The "Dry Corridor" in Central America drives 400000 people northward every year, and one in every three teenagers in sub Saharan Africa is considering climate migration. The world's first "climate refugee camp" has emerged in Boduakari District, Bangladesh, where 32000 people have permanently lost their land ownership due to rising sea levels. The European Border Agency warns that overloading Mediterranean climate refugee ships by 400% has become the norm, and the number of people drowning due to illegal immigration will surge by 220% year-on-year in 2023.

The failure of global governance
The Paris Agreement requires developed countries to provide $100 billion in climate funding annually, but an audit by the Organisation for Economic Co operation and Development (OECD) shows that only $83.3 billion will actually be disbursed in 2022, with 60% being in the form of loans. The United Nations Intergovernmental Panel on Climate Change (IPCC) estimates that current voluntary emission reduction commitments by countries will lead to a global warming of 2.8 ℃ by the end of the century. The total carbon emissions of 54 African countries account for only 3% of the world's total, but they bear 83% of the climate economic losses
Countdown to climate crisis
The World Bank model shows that if the temperature rises above 2 ℃, the global GDP will permanently lose 15-25%, and the agricultural production potential in tropical regions will decrease by 50%. The United Nations Development Programme (UNDP) warns that under current emission reduction efforts, humanity will exhaust the 1.5 ℃ temperature control target carbon budget within 8.5 years.
