Mosquito-free havens will start to disappear by mid-century, study warns
FRISCO — Island birds, including endangered species in the Hawai‘i archipelago, are facing a serious threat, as diseases carried by mosquitoes are due to expand into higher elevation safe zones.
With warming temperatures, mosquitoes will move farther upslope and increase in number, and mosquito-friendly temperatures are expected by mid-century, according to a new study by researchers with the U.S. Geological Survey and the University of Wisconsin-Madison. Future increases in rainfall will likely benefit the mosquitoes as well.
FRISCO — As sea level rises, Hawaii’s beaches are on track to shrink by 20 to 40 feet during the next few decades, scientists announced in a new study.
“When we modeled future shoreline change with the increased rates of sea level rise projected under the IPCC’s “business as usual” scenario, we found that increased SLR causes an average 16 – 20 feet of additional shoreline retreat by 2050,” said lead author Tiffany Anderson, a post-doctoral researcher at the UHM School of Ocean and Earth Science and Technology.

Duke University researchers say community based conservation measures also needed
FRISCO —Hawaii’s spinner dolphins need federal regulations limiting human access to resting areas, but that alone won’t be enough to help them survive in the long run. Along with any new federal rules, resource managers will also have to work to develop local community-based conservation measures, which can be tailored to how individual bays are used, according to new research by Duke University.
FRISCO — Meteorologists are keeping a close eye on what they describe as a hyperactive tropical Pacific Ocean, and especially on Hurricane Iselle, which is headed straight toward Hawaii with current sustained winds of 140 mph.
Iselle is expected to weaken before nearing the islands in about three days, but could still be packing a tropical storm-force punch, with winds of 60-60 mph. The Category 4 storm is expected to maintain strength for the next day or so before moving over cooler water and weakening. Continue reading “Is Hurricane Iselle headed for Hawaii?”→
FRISCO — A team of scientists have taken a close look at coastal erosion trends in Hawaii and determined that sea-level rise is the main driver, outweighing other factors like waves, sediment supply and coastal development.
The researchers from the University of Hawaii – Manoa, School of Ocean and Earth Science and Technology and the State of Hawaii, Department of Land and Natural Resources said that knowing that sea-level rise is a primary cause of shoreline will help resource managers and planners going forward.

Study projects two to three times as many storms by the end of the century
By Summit Voice
SUMMIT COUNTY — Large scale shifts in hemispheric circulation patterns and ocean temperatures are likely to steer more hurricanes toward the Hawaiian Islands in coming decades.
A poleward shift of the subtropical jet stream and warmer temperatures over the equatorial central Pacific will combine to make the storms two to three times as likely by the last quarter of the century, according to scientists with the International Pacific Research Center, University of Hawaii at Manoa.
