Simpler route to global warming management being missed

A scientific report has stated that while the world is looking at carbon dioxide as the major concern with respect to climate change, other possibly easier ways of bringing down global warming are being missed out on.

The Arctic Monitoring and Assessment Programme (AMAP) set up by the Arctic Council produced the said report, which claimed that the temperature on earth could be brought down by earth by approximately 0.2 degrees Celsius between now and 2050 by putting down a heavier hand on the other pollutants except carbon dioxide, such as methane, black carbon and atmospheric ozone.

Methane is a greenhouse gas like carbon dioxide, but is 20 times more dangerous in its potential for global warming. However, it is much easier to deal with, as it is a short-lived pollutant. An even shorter life-span is carried by black carbon, which is produced from incomplete burning of fossil fuels.

The accumulation of greenhouse gases, which might even remain hanging in the atmosphere for over a century, is the main cause behind global warming.

“Actions to reduce methane emissions could slow the global warming expected by 2050 by approximately 0.2 degree Celsius. A reduction of about 0.25 degree Celsius in the Arctic could be achieved through global actions to reduce emissions of black carbon and co-emitted air pollutants,” the report, released during the Paris conference, says, according to a statement by the AMAP.

“Unlike carbon dioxide, short-lived climate pollutants (SLCPs) have a relatively short residence time in the atmosphere (of a few days to about a decade). The shorter the lifetime, the more quickly atmospheric concentrations can be reduced by lowering emissions. This means that action on SLCPs has the potential to slow the rate of climate warming on a comparatively shorter time scale,” said the statement.

The statement additionally said that this step should not be seen as a replacement to the actions being taken on carbon dioxide and harsher greenhouse gases.

“Action on black carbon and ozone has added benefits since these pollutants are also harmful to human health,” it said.

The research also showed that if black carbon and methane were aggressively curbed, the temperature rise since the industrial age could easily be stalled at the 2 degrees Celsius mark.

Climate Change Not A Hoax: Trump

U.S. President Donald Trump is backing off his claim that climate change is a hoax.

In an interview broadcast Sunday, Trump told CBS-TV’s 60 Minutes “I think something’s happening. Something’s changing and it’ll change back again…I’m not denying climate change, but it could very well go back. You know, we’re talking about over millions of years.”

Trump has over the years called global warming a hoax and had once called it a Chinese plot aimed at wrecking the U.S. economy.

Trump told 60 Minutes he does not know if global waning is manmade, despite the scientific research showing that pollution and human activity is the major contributor. He said he does not want to give “trillions and trillions of dollars” and lose “millions and millions of jobs” to prevent it.

Most scientists link a warming planet with storms that are more intense. Hurricane Michael slammed into the Florida Panhandle last week as the strongest storm to strike the continental United States in nearly 50 years.

Trump said there have been hurricanes that were “far worse” than Michael and said scientists calling for action on climate change have a “very big political agenda.”

Meanwhile, the town of Mexico Beach, Florida was just about wiped off the face of the earth by Hurricane Michael.

“Mexico Beach is devastated,” Florida Governor Rick Scott says. “It’s like a war zone.”

Michael’s 250 kilometer per hour winds left only a handful of buildings standing. Concrete slabs are left where houses and stores thrived. Only a few trees are left. The main U.S. highway that goes through the town is not drivable.

Mexico Beach police chief Anthony Kelly told VOA’s Spanish Service, “When you come here and see the devastation, it’s hard, it’s emotionally hard.”

“We know each person in the majority of the houses. They know us,” Kelly said. “All these people are close to us. And now we’re going around the neighborhoods making sure that they’re not in any of these houses that are so extremely damaged.”

“Looking in the debris, seeing photos of grandkids, people that we know that have come back here year after year, that’s the emotional side,” he said. “I’ve got officers that this is their first catastrophic event, and it’s hard to explain to them, you know, it’s going to get better, because they’re seeing reality.”

The town’s medical manager, Patricia Cantwell, said, “It’s extremely sad that the devastation has been so rampant throughout the Panhandle” of the state.

“Having lived through Hurricane Andrew in south Florida (in 1992), it’s going to take a while,” she told VOA. “It’s one day at a time. It looks overwhelming to start, but, you know, one day at a time. It’s going to take years to get things back up and running.”

Brock Long, the head Federal Emergency Management Agency, said the death toll in Mexico Beach could rise, as rescue workers continue to search the rubble left behind by the storm. It could take another 10 days to compile a damage estimate.

Some physical structures in the town were lifted off their moorings and moved hundreds of meters away by the winds and storm surge from the storm. Other buildings were left in masses of debris, demolished beyond recognition.
