The projections highlight how climate change could reshape weather patterns across parts of Asia, with some cities expected to face simultaneous temperature increases and declining annual rainfall.

A visual analysis published by World Visualized, based on the climate research, identified Yangon, Manila and Jakarta among the cities projected to face some of the sharpest combinations of rising heat and falling precipitation by mid-century.

Yangon, formerly known as Rangoon, could experience average temperatures rising by about 5.9 degrees Celsius alongside a projected annual rainfall decline of roughly 162 millimetres.

Manila is projected to warm by approximately 3.9 degrees Celsius while losing around 155 millimetres of annual precipitation, while Jakarta could see temperatures increase by 3.1 degrees Celsius with rainfall decreasing by nearly 196 millimetres.

Climate scientists warn that hotter and drier conditions could intensify drought risks, strain water supplies and increase the frequency of heat-related illnesses in densely populated urban areas.

Other cities highlighted in the projections, including Hiroshima, Taipei and Macau, are expected to become significantly drier even with more moderate temperature increases.

Meanwhile, Tehran, Tashkent and Jaipur are projected to experience some of the sharpest temperature increases in the study despite relatively smaller declines in rainfall. Tehran could warm by more than 6 degrees Celsius under high-emissions scenarios by 2050.

The findings align with broader warnings from the Intergovernmental Panel on Climate Change (IPCC), which has repeatedly identified Asia as one of the regions most vulnerable to climate-related disasters, including extreme heat, flooding, droughts and food insecurity.

According to the World Meteorological Organisation (WMO), Asia has warmed faster than the global average in recent decades, with climate impacts increasingly affecting economic productivity, infrastructure and public health.

Cities such as Jakarta and Manila already face major environmental pressures linked to flooding, sea-level rise and rapid urbanisation. Experts warn that reduced rainfall combined with rising temperatures could place additional stress on energy systems and drinking water supplies.

Urban planners and climate researchers say governments across Asia may need to accelerate investment in heat-resilient infrastructure, sustainable water management and climate adaptation policies to reduce long-term risks.

The projections also reinforce concerns that developing countries in Asia could face disproportionate economic and social consequences from climate change despite contributing less historically to global greenhouse gas emissions.

The investment package includes €14 billion from French public and private entities and €9 billion from African investors. The funds will focus on sectors including energy transition, digital technology and artificial intelligence , the maritime economy, and agriculture.

“I simply wanted to announce today that, through this mobilisation and everything we have achieved, there are very tangible results for the African continent,” Macron said.

“Today, thanks to your commitment and the work done, we are announcing €23 billion in investment for Africa—€23 billion. This includes €14 billion from the French companies gathered here—major groups, mid-sized firms, and SMEs—who are investing €14 billion across the continent.”

Macron said the investments would support projects in Kenya and other African countries represented at the summit.

“I applaud all the leaders present today; these investments are being made here in Kenya and across all the nations represented, and they will create over 250,000 direct jobs in both France and Africa,” he added.

The Africa Forward summit is part of France’s broader effort to rebuild partnerships across Africa through economic cooperation and investment.
