Climate change in Asia
Climate change is particularly important in Asia, as the continent accounts for the majority of the human population. Warming since the 20th century is increasing the threat of heatwaves across the entire continent. Heatwaves lead to increased mortality, and the demand for air conditioning is rapidly accelerating as the result. By 2080, around 1 billion people in the cities of South and Southeast Asia are expected to experience around a month of extreme heat every year. The impacts on water cycle are more complicated: already arid regions, primarily located in West Asia and Central Asia, will see more droughts, while areas of East, Southeast and South Asia which are already wet due to the monsoons will experience more flooding.
The waters around Asia are subjected to the same impacts as elsewhere, such as the increased warming and ocean acidification. There are many coral reefs in the region, and they are highly vulnerable to climate change, to the point practically all of them will be lost if the warming exceeds 1.5 °C (2.7 °F). Asia's distinctive mangrove ecosystems are also highly vulnerable to sea level rise. Asia also has more countries with large coastal populations than any other continent, which would cause large economic impacts from sea level rise. Water supplies in the Hindu Kush region will become more unstable as its enormous glaciers, known as the "Asian water towers", gradually melt. These changes to water cycle also affect vector-borne disease distribution, with malaria and dengue fever expected to become more prominent in the tropical and subtropical regions. Food security will become more uneven, and South Asian countries could experience significant impacts from global food price volatility.
Historical emissions from Asia are lower than those from Europe and North America. However, China has been the single largest emitter of greenhouse gases in the 21st century, while India is the third-largest. As a whole, Asia currently accounts for 36% of world's primary energy consumption, which is expected to increase to 48% by 2050. By 2040, it is also expected to account for 80% of the world's coal and 26% of the world's natural gas consumption. While the United States remains the world's largest oil consumer, by 2050 it is projected to move to third place, behind China and India. While nearly half of the world's new renewable energy capacity is built in Asia, this is not yet sufficient in order to meet the goals of the Paris Agreement. They imply that the renewables would account for 35% of total energy consumption in Asia by 2030.
Climate change adaptation is already a reality for many Asian countries, with a wide range of strategies attempted across the continent. Important examples include the growing implementation of climate-smart agriculture in certain countries or the "sponge city" planning principles in China. While some countries have drawn up extensive frameworks such as the Bangladesh Delta Plan or Japan's Climate Adaptation Act, others still rely on localized actions that are not effectively scaled up.
Historical emissions from Asia are lower than those from Europe and North America. However, China has been the single largest emitter of greenhouse gases in the 21st century, while India is the 3rd-largest, Russia is 4th, while Japan and South Korea rank 5th and 7th. Around 70% of India's energy comes from fossil fuels, while this figure reaches 80-90% in China, Japan and the Republic of Korea. As a whole, Asia currently accounts for 36% of world's primary energy consumption, which is expected to increase to 48% by 2050. By 2040, it is also expected to account for 80% of the world's coal and 26% of the world's natural gas consumption. While the United States remains the world's largest oil consumer, by 2050 it is projected to move to third place, behind China and India.
After 2040, Asia would likely account for over half of the world's electricity consumption, and around 40% will likely be generated from coal burning. Asia is expected to import more oil and gas in the future than it does now, and would likely account for 80% of the global energy market in 2050. In particular, there are 11 developing countries in Asia which have a large energy consumption yet also lack energy security.
Starting from the 20th century, there has been clear warming across the entire continent. The frequency of cold days and nights decreased, which had also lowered the need for heating. Yet, the demand for air conditioning had increased far more as the frequency of hot days and warm nights had also grown, which had also increased the strain on power grids. Hot temperature extremes appear to have increased the most in Central and West Asia, while heatwaves in East and South Asia are becoming longer, more frequent and more severe.
In 2016 and 2018, Asia has already experienced extreme heat that would have been statistically impossible without climate change. New Delhi broke an all-time record when it reached 48 °C (118 °F) in 2018. North Asia has the coldest climate due to its proximity to the Arctic, but it also experiences greater relative warming due to what is known as the arctic amplification. This has led to permafrost thaw, which acts as a climate change feedback and also places large quantities of infrastructure at risk of collapse.
