New reporting from researchers, including work covered by the Natural History Museum and Phys.org, suggests shifting climate conditions could change the risks humans face from deadly rodent-borne diseases. Changes in temperature and rainfall may alter rodent habitats and populations, potentially bringing infected animals into closer contact with people and expanding where diseases like hantavirus and Lassa fever pose a threat.

Scientists report that as the Pacific Ocean warms, its water-age structure is behaving counterintuitively: young water at the surface appears to be aging, while older deep water is getting younger, a reversal of established circulation patterns. The finding suggests climate change may be disrupting the ocean's overturning circulation, with potential consequences for heat and carbon storage. Researchers say the shift warrants closer monitoring of how the Pacific redistributes heat as global temperatures rise.

Scientists are developing new ways to control mosquitoes, the animal that kills more people than any other on Earth. As the climate warms, mosquito seasons are growing longer, giving the insects more time to spread dangerous diseases such as malaria and dengue. Reports highlight how extended warm periods are expanding the threat to new regions and prompting research into novel control methods.

New research suggests climate change could significantly alter the future of Chinese milk vetch, a legume widely grown as green manure in southern China's rice paddies. Shifting temperatures and rainfall patterns may affect where and how well the plant grows, with implications for soil fertility and sustainable rice farming in the region.

A new AI model has been developed to demonstrate how climate-related events influence human migration patterns, according to Technology Org. The tool aims to shed light on the connections between extreme weather, environmental change and population movement, offering researchers and policymakers a clearer picture of where and why people relocate when climate pressures mount.

Climate researchers are explaining how a Kelvin Wave affects ocean waters. A Kelvin Wave is a large-scale movement of warm water along the equatorial Pacific that can raise sea surface temperatures and influence weather patterns, including developments tied to El Nino. Scientists say understanding these waves helps forecast shifts in ocean conditions and global climate impacts in the months ahead.

Researchers in the United Kingdom and Australia have built an open source project, covered by The Conversation, that measures the effects an individual fossil fuel project has on climate outcomes. The tool aims to assess emissions impacts at the project level rather than nationally, drawing on academic collaboration across the two countries. It is being shared among climate-focused readers online.

A systematic overview of climate actions for health in cities has been published in Nature, compiling evidence on how urban climate measures affect public health. The review brings together research on interventions such as reducing emissions and greening cities, assessing their health outcomes. It offers city planners and policymakers a consolidated evidence base for choosing climate actions that also protect residents' health.
