Japan to extend weather forecasts in response to climate change

Japan's meteorological agency has announced plans to extend its weather forecasts from seven days to two weeks, in response to the increasing frequency and intensity of extreme weather events driven by climate change. The Japan Meteorological Agency (JMA) currently issues forecasts for the next seven days, but an expert report commissioned by the agency found that advancements in climate data observations and simulations make extending the forecast period both possible and desirable.

JMA official Masayuki Kyoda emphasized that the changes would aid in better preparations for extreme weather, which has become more common in recent years due to global warming. Kyoda cited the example of the two-week time frame needed to secure manpower for snow removal as a reason why extended forecasts would be beneficial. The JMA hopes to implement the changes by 2030.
