Solving for climate: (Health and safety) in (climate) numbers
We’ve all probably heard about how climate change is affecting the ice sheets and polar bears, but what about human health? More severe and numerous floods, droughts, and heat waves impact a wide range of health outcomes, and shifting biomes may spread diseases to new places. How do scientists understand which portions of health effects are caused by climate change, and how can health organizations be prepared?

The Earth’s oceans play a crucial role in regulating the planet’s climate by absorbing and storing vast amounts of heat and carbon dioxide from the atmosphere. However, due to human activities such as the burning of fossil fuels and deforestation, the oceans are warming at an alarming rate. This increase in ocean temperature is causing a range of devastating impacts, from more frequent and severe storms to rising sea levels and bleached coral reefs.

Did you ever wonder how random flashes of fireflies gradually acquire synchrony? Studies have shown that this surreal coordination of twinkling occurs through a natural cadence among certain species of fireflies during the mating season.
Read MoreHalloween special: Nessie & the kraken
We’ve all heard stories about fantastical creatures that people swear they’ve seen and have evidence of but can never be confirmed. Think Bigfoot or the Loch Ness monster. Mermaids or the Kraken. While there’s no evidence backing the existence of these creatures, either in present day or at any point in the past, there must…

Tommy Dickey is an emeritus oceanographer from U.C. Santa Barbara and Naval Operations Chair in Ocean Sciences. His modeling and observational research yielded ocean monitoring technologies and tools. For retirement, Tommy trains and deploys Great Pyrenees as therapy dogs, while studying scent dogs’ capacity to detect COVID-19.

This episode is about how satellite technology is being used to study a big chunk of the earth’s surface. Seventy percent of the earth comprises water but we know very little about it. Color sensors aboard some satellites can actually reveal a lot about phytoplankton or microalgae blooms that are linked to ocean temperatures. These tiny organisms contribute to half the photosynthesis on the planet.

Brian Huber is a climate detective at the Smithsonian who grew up collecting arrowheads in the woods of Ohio, but now collects and studies fossils from sediment cores. Brian uses fossils of tiny organisms − foraminifera − to track climate over millions of years, including the Cretaceous Hot Greenhouse climate.
