Hurricanes create natural climate labs in Puerto Rico
(21 Feb 2019) LEADIN:
The hurricanes that pounded Puerto Rico in 2017 may give scientists clues to how the world will respond to climate change and increasingly severe weather.
Researchers are running controlled studies looking at how tropical rain forests are reacting to higher temperatures, as well as seeing how Hurricane Maria affected the environment.
STORYLINE:
The hurricanes that pounded Puerto Rico in 2017, blasting away most of its forest cover, may give scientists clues to how the world will respond to climate change and increasingly severe weather.
Here at El Yunque researchers from the US Forest Service are running controlled studies, which they see as a once in a century opportunity to look a two major aspects of climate change.
Tana Wood oversees a team testing how plants themselves respond to higher temperatures.
The 2017 hurricane season, with Maria following a lesser blow from Hurricane Irma, has also given them a chance to see how storms affect the recovery of ecosystems already under stress.
This is a key concern in the Caribbean area, where scientists say warmer temperatures could lead to more intense hurricanes.
The researchers make their way to three plots surrounded by infrared panels that heat the air and soil by 4 degrees Celsius.
The vegetation here is shorter and a bit browner compared with the three unheated control plots.
The warmed plots run on 480 volts of electricity, and while the lines are isolated from the soil, the scientists use insulated boots to ensure they avoid getting electrocuted.
Rainforests are incredibly important for understanding global climate, because they exchange more carbon dioxide with the atmosphere then any terrestrial biome. And so anything that happens in these ecosystems that can affect that balance of how much carbon dioxide they are taking in, that could have an affect the climate on a global scale explains Wood.
Intern Virginia Rose Seagal says: Climate change is the biggest issue of our time, it affects everybody right now, and it's going affect all of our futures. It's important to study what's happening to our planet right now, what's there left to save on this planet because so much is disappearing such at rapid speed.
Nearby a plant physiologist clamps what looks like a small compact mirror around a dark green leaf to measure photosynthesis.
Each leaf takes between thirty minutes to an hour.
The researchers are looking at how temperatures affect basic processes such as photosynthesis, where plants transform sunlight into energy while absorbing carbon dioxide and releasing that gas and oxygen into the atmosphere.
They're also studying nutrients and microbes in the artificially warmed plots of land, keeping the samples in a -80 Celsius (-112 Fahrenheit) degree refrigerator until they can be sent for analysis to a lab in California.
We are measuring as we said as many things as we can in terms of carbon cycling in the forest, so initially in response of the warming we're seeing an increases in the amount of the carbon dioxide released from the soil and through the microbial processes, and then we've seen also some decline in plant photosynthesis. But those are initial findings and what that means in the longer term, whether these plants will acclimate is one of the question we are interested in says Wood.
Tropical forests play a key role in recycling carbon dioxide, and they store about a third of the world's carbon.
It's now in its fourth year.

Man Sentenced for Speeding Away with Border Patrol Agent Hanging out of Driver’s Window
SAN DIEGO – John Leland Combs was sentenced to 30 months in prison today for assaulting a U.S. Border Patrol agent by speeding away in a stolen car while the agent was leaning inside the driver’s window, and then leading Border Patrol agents on a high-speed chase on State Route 94, endangering everyone on the road that morning.
Combs was convicted by a federal jury on November 6, 2018 of assault on a federal officer and high speed flight from a checkpoint.
According to evidence presented at trial, the assault occurred during the early morning hours of September 2, 2017. Agent Norberto M. Ribac was assigned to the Brown Field Border Patrol Station All-Terrain Vehicle (ATV) Unit patrolling in the area of Tecate, California. At approximately 5:40 a.m., Agent Ribac discovered northbound shoeprints in the sand approximately 300 yards west of the Tecate Port of Entry. Agent Ribac followed the footprints to Industrial Road, where he discovered Combs standing next to his car, a stolen Hyundai Genesis, and talking on his cell phone, mere yards north of the border fence in Tecate.
Agent Ribac approached Combs and asked him if there was anything or anyone in the car. Combs said he was alone and voluntarily opened the trunk of the car for Agent Ribac to inspect. As Agent Ribac requested registration and records checks for the car, Combs got inside the car in an apparent attempt to leave the area. When Agent Ribac reached into the car through the driver’s side window to turn the engine off, Combs sped off. While Agent Ribac was attempting to free himself from the moving car, the car struck him on his right elbow and on the right side of his head, breaking his ATV helmet.
In an attempt to flee the State Route 94 Checkpoint, Combs hit speeds over 70 mph while swerving in and out of traffic on a winding two-lane highway. As Combs veered over the cone lane and into the eastbound lane of the checkpoint, video footage showed the agents successfully deploying spike strips. Combs eventually lost control of the car and swerved into a residential driveway. He attempted to flee on foot, but was quickly arrested.
“Agent Ribac put his life on the line to keep our community safe,” said U.S. Attorney Robert Brewer. “I’m very glad it’s the defendant, and not the brave agent, who is paying the price for this audacious crime. We will use our legal arsenal to vigorously prosecute those who assault dedicated U.S. Border Patrol agents and endanger the public with dangerous escape attempts.”
“We are grateful to the U.S. Attorney’s Office for their tenacity and professionalism in presenting a strong case in support of our agent,” said San Diego Sector Chief Patrol Agent Rodney Scott. “The community in which we serve has spoken in favor of law and order, and every agent in this Sector appreciates the support as we work to provide a secure border.”
The case was prosecuted by Assistant United States Attorneys Ryan Sausedo and Katherine McGrath.
We Want To Thank All The Brave Men And Women Who Have Dedicated Their Lives To Keeping Our Country Safe.
God Bless America!
