Patients using cannabis as alternative to prescription drugs
A new study by health experts at the University of Georgia suggests that people are using marijuana as an alternative to prescription medications for ailments that range from pain to sleep disorders.
That trend translates to about $165.2 million in savings for Medicare’s prescription drug benefit program in 2013, the researchers reported in the journal Health Affairs.The results suggest that if all states had implemented medical marijuana the overall savings to Medicare would have been around $468 million.

From aspens in the Williams Fork Range to the red rocks of Glenwood Springs Canyon, there’s incomparable beauty in the hills of Colorado, and nothing like a little snow to make it all shine!
Air pollution is changing plant odors, which confuses bees and makes them less efficient at foraging and pollinating plants, Penn State researchers said in a new study that shows how ozone breaks down plant-emitted scent molecules.
The chemical interactions decrease both the scent molecules’ life spans and the distances they travel, the scientists reported in the new study. They found that plant-emitted hydrocarbons break down through chemical interactions with certain air pollutants such as ozone. This breakdown process results in the creation of more air pollutants, including hydroxyl and nitrate radicals, which further increase the breakdown rate of plant odors.

After studying the impacts of recent droughts in the Amazon, researchers are warning that the rainforest may gradually be losing its ability to remove carbon from the atmosphere. But their study also shows that the ecosystem is resilient and can recover quickly in between droughts.
The study used data from from droughts in 2005 and 2010, finding that tree growth slowed across the vast forests of the Amazon Basin. Long-term measurements from theRAINFOR network spanning nearly a hundred locations across the Amazon Basin helped show how the rainforest temporarily lost biomass. Both droughts killed many trees, but the 2010 drought also had the effect of slowing the growth rates of the survivors, suggesting that many trees were adversely affected but not to the point of death.

Deadly heatwaves and flooding part of emerging pattern of extremes
Blistering, record heat in the Southwest helped propel the lower 48 states to a new high-temperature record in June, with an average reading of 71.8 degrees Fahrenheit for the month. That included a new monthly temperature record set in Death Valley National Park, where the average temperature in June was 101.9 degrees Fahrenheit.
The warmest-ever June reading broke the record set during the Dust Bowl era, in 1933, according to NOAA’s National Centers for Environmental Information. The year-to-date is the third-warmest on record, the monthly state of the climate summary report said.
British Antarctic Survey scientists to monitor impacts of ash deposits
A volcanic eruption in the remote South Sandwich archipelago, near the tip of the Antarctic Peninsula, may threaten the largest known colony of chinstrap penguins, according to scientists with the British Antarctic Survey who have been monitoring the eruption.
The Mt. Curry volcano on Zavodovski Island has been erupting since March, sending ash toward the penguin enclave. The uninhabited island is part of the British Overseas Territory of South Georgia and the South Sandwich Islands. After reports of a 7.2 magnitude earthquake last month, researchers confirmed from satellite imagery that not one, but two volcanoes are erupting in the South Sandwich Islands — Mt. Curry on Zavodovski Island to the north of the archipelago and Mt. Sourabaya on Bristol Island to the south. Continue reading “Eruption poses threat to huge penguin colony”→
Average temperature for the month more than 6 degrees above the historic norm
The deadly heatwave that spread across the southwestern U.S. in June also brought a new record high average temperature to Death Valley, one of the hottest places on Earth. According to the National Park Service, last month was the warmest June on record in the national park, with the average temperature for the whole month registering at 101.9 degrees Fahrenheit — about 6 degrees above the long-term average.
Death Valley’s average daily high temperature this June was 115.5 degrees Fahrenheit and the average overnight low was 88.2 degrees. In spite of a record-setting average temperature, Death Valley only set a new daily record one day last month, with 126 degrees recorded on June 21, 2016. The highest temperature ever recorded in Death Valley in June was just a few years ago: 129 degrees on June 30, 2013. Continue reading “Climate: Death Valley sets heat record in June”→
