May led a delegation to Kenya this week to advance a landmark partnership between the State of California and the Government of Kenya focused on climate action, clean transportation, climate smart agriculture, public health and innovation. Chancellor May was joined by Samuel Assefa, director of the Governor’s Office of Land Use and Climate Innovation, as well as several ³Ô¹ÏºÚÁÏ representatives. The delegation was jointly organized by UC Davis Global Affairs, Institute of Transportation Studies and the Office of the Special Envoy on Climate of Kenya.</span></p> November 13, 2025 - 1:06pm Katherine E Kerlin /news/chancellor-may-leads-delegation-kenya-advance-california-kenya-climate-and-trade-partnership How Climate Change Brings Wildlife to the Yard /climate/news/how-climate-change-brings-wildlife-yard <p>As climate change increases the frequency of droughts, UCLA and UC Davis researchers found one overlooked side effect: People report more conflicts with wildlife during drought, when resources are scarce.</p><p>For every inch that annual rainfall decreases, scientists found a 2% to 3% increase in reported clashes with a variety of carnivores during drought years, according to <a href="https://www.science.org/doi/10.1126/sciadv.adx0286">a paper published today, Nov. 12, in the journal Science Advances</a>.&nbsp;</p> November 12, 2025 - 4:04pm Katherine E Kerlin /climate/news/how-climate-change-brings-wildlife-yard Mechanical Power by Linking Earth’s Warmth to Space /news/mechanical-power-linking-earths-warmth-space <p>Engineers at the University of California, Davis, have invented a device that can generate mechanical power at night by linking the natural warmth around us to the cold depths of space. The invention could be used, for example, to ventilate greenhouses or other buildings.

It points to the need for joint surface and groundwater management.

During this time, continental carbon reservoirs expanded as carbon dioxide decreased in the atmosphere.</span></p><p><span lang="EN-US">But that trend has reversed. Fossil fuel consumption, among other sources of pollution, have resulted in increasing atmospheric and oceanic temperatures, leading to ice sheet melt and unprecedented shifts in our environments.&nbsp;</span></p> October 31, 2025 - 10:42am Andy Fell /blog/deep-water-sediments-reveal-patterns-extraterrestrial-influence-earths-ancient-climates New Species of Spider Discovered, Just in Time for Halloween /climate/news/new-species-spider-discovered-just-time-halloween UC Davis scientists have discovered a new species of trapdoor spider in California's coastal sand dunes.
