Since the start of the 21st century California and Nevada have suffered extreme wildland fires and droughts that have caused devastating impacts to ecosystems and society. A common feature of these events has been very high evaporative demand—the “thirst” of the atmosphere—which has largely been driven by increased air temperatures caused by anthropogenic climate change
The study led by the Alaska Center for Climate Assessment and Policy (ACCAP), a CPO RISA team, reveals multiple weather-related impacts from extreme events in Alaska and suggests the frequency and timing of these extreme events will change in the decades to come.
Threatened resources include high-value coastal infrastructure and the millions of dollars that ocean ecosystems add to Guam’s economy annually, according to the report.
Dr. William Howe, Climate Assessment Specialist for the CPO RISA Southern Climate Impacts Planning Program (SCIPP) team, released three new studies on the challenges of communicating weather and climate information. He compared tweets of severe weather events between the National Weather Service and local television stations, examined the relationships between SCIPP’s primary stakeholders and sources of climate information, and conducted an experiment in which messages were framed differently to see how residents of Texas responded.
The new web portal provides data on a number of indicators that track the status and trends of seven major marine ecosystems across the United States as well as a national synthesis.
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.
