Obama expands Hawaii marine reserve in final push on climate

U.S. President Obama speaks about transportation infrastructure during a visit to the Port of Wilmington in WilmingtonBy Roberta Rampton WASHINGTON (Reuters) - U.S. President Barack Obama will dramatically expand the Papahānaumokuākea Marine National Monument off the coast of Hawaii on Friday, the White House said, an action that will ban commercial fishing from more than 582,500 sq miles (1.5 million sq km) of the Pacific Ocean. Obama will visit the protected area on Sept. 1 to draw attention to the threat that climate change poses to oceans, traveling to Midway Atoll - a remote coral reef that was the site of a pivotal World War Two battle and is now known for its sea turtles, monk seals, and millions of seabirds. Obama, who was born in Hawaii and spent most of his childhood there, made curbing climate change a central part of his time in the White House, which draws to a close on Jan. 20.

Climate change taking toll on American pika's Western lands

A new study shows populations of the rabbit-like animal known as the American pika are vanishing in many mountainous areas of the West as climate change alters habitat. The U.S. Geological Survey research unveiled Thursday, Aug. 25, 2016, found ranges of the mountain-dwelling herbivore are decreasing in southern Utah, northeastern California and in the Great Basin that covers most of Nevada. (Shana S. Weber/USGS, Princeton University via AP)SALT LAKE CITY (AP) — Populations of a rabbit-like animal known as the American pika are vanishing in many mountainous areas of the West as climate change alters its habitat, according to findings released Thursday by the U.S. Geological Survey.

Climate change to double number of hay fever sufferers

By mid-century, some 77 million people in Europe will be hit by hay fever misery, up from 33 million today, they reported in the journal Environmental Health PerspectivesClimate change and the spread of invasive ragweed are set to double the number of seasonal allergy sufferers across Europe, with similar impacts likely in North America, researchers said Thursday. By mid-century, some 77 million people in Europe will be hit by hay fever misery, up from 33 million today, they reported in the journal Environmental Health Perspectives. "Ragweed pollen allergy is likely to become a major health problem across much of Europe," said lead author Iain Lake, a researcher at the University of East Anglia in England.

Florida hurricane forecast remains uncertain, but trends in state's favor

Florida hurricane forecast remains uncertain, but trends in state's favorFor days, a war has been raging between two of the premiere computer models used to help predict the weather. On the one side, there's the National Weather Service's Global Forecast System, or GFS, which has maintained that a tropical wave moving across Puerto Rico and Hispaniola will not intensify into a hurricane and strike Florida this weekend.  But other models have consistently outshone the GFS in both routine and high impact, high risk forecast situations. On the other side of the battle is the European, or Euro model, which is run by the European Center for Medium Range Weather Forecasting in England.  SEE ALSO: The Weather Service is getting better supercomputers The Euro, which gained notoriety by catching on to Hurricane Sandy's unprecedented and catastrophic left hook into New Jersey a week in advance, has rattled Florida with its depiction of an intense tropical storm or hurricane hitting the southern part of the state this weekend.  Run after run, the Euro had stuck to its guns for the past three days, insisting that the area of inclement weather designated as "Invest 99L" would soon become Hurricane Hermine, potentially going on to menace Gulf Coastal states as a major hurricane of Category 3 intensity or greater. Euro may have just surrendered The battlefield may have just changed significantly, though. It's unclear if a peace treaty has been signed, or if this is just a temporary lull in the fighting, but the afternoon run of the Euro model trended toward the GFS solution of a weaker storm. In other words, it is no longer showing an intense storm hitting Florida on Sunday, and then intensifying over the unusually warm waters of the Gulf of Mexico.  This news is being met with cautious relief on social media. For example, Miami NBC-TV meteorologist John Morales welcomed the new computer model trend.  Weather Channel meteorologist Justin Abraham comically celebrated what he sees as a potential GFS victory over the top-seeded European model.  However, Floridians shouldn't let down their guard yet, since the swirling cloud mass located north of Haiti could still persevere despite two main challenges.  Invest 99L has been contending with layers of dry air that have stifled the development of thunderstorms near the center of the storm. Such thunderstorms are needed in order for the weather system to form a closed area of low pressure at the surface and intensify. The wind shear is forecast to diminish starting in about 24 to 36 hours, at which point it's possible both the Euro and GFS will be wrong, and the storm will intensify rapidly.  "Although upper-level winds are not conducive for significant development during the next day or so, they could become a little more favorable over the weekend or early next week when the wave is expected to approach southern Florida or the southeastern Gulf of Mexico," the National Hurricane Center said in a 2 p.m. ET statement on the weather system. The Hurricane Center lowered Invest 99L's chances of developing into a tropical depression, tropical storm or hurricane to 70 percent through 5 days, down from 80 percent earlier in the day.  For now, Invest 99L looks like a poor excuse for a tropical weather system that is inspiring trepidation in a coastal state like Florida. Its center is exposed and comprised only of low-level clouds, and the largest thunderstorms are displaced several hundred miles away from the center.  In short, it looks like garbage, from a tropical meteorology perspective.  Whether it turns into something more impressive remains to be seen, but for now, it's encouraging that the great model war of  August 2016 may be coming to an end.

Climate Change Is Likely to Cause Allergy Misery for Millions

Climate Change Is Likely to Cause Allergy Misery for MillionsWant to know what pollen season could be like in a hotter world? Imagine standing under this tree and trying to breathe: If the rate of warming continues, the number of people suffering from ragweed allergies could jump from 33 to 77 million by 2050. That’s just for Europe: The worldwide toll would obviously be even bigger. Two-thirds of the spread of sinus-obliterating allergies is predicted to be directly tied to climate change.
