The discrepancies between simulations and reconstructions obstructs our ability to gain a better understanding of climate from these natural experiments.
In a recent paper published in Science, authors analyze new paleoclimate data in the form of coral samples from the Tropical Pacific. These include a consistent proxy record for variables such as sea surface temperature.
The study highlights scientists’ ability to indirectly measure large scale global processes through observation platforms that confirm models and shows how anthropogenic effects (e.g. greenhouse gases and ozone) interact to impact large scale global circulation systems.
Extreme temperature events threaten vulnerable populations with limited access to shelter and water and/or with pre-existing health conditions.
The Climate Program Office’s Alaska RISA team (Alaska Center for Climate Assessment and Policy), in partnership with the International Arctic Research Center and the University of Alaska, Fairbanks, has released a new report, Alaska’s Changing Environment, documenting recent observed profound changes in the environment related to extreme weather events and deviations from the historical climate.
Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather.
