Climate change concerns highest in Northeast, Western US: poll

Climate change concerns highest in Northeast, Western US: poll Concern over climate change is highest in the Northeastern and Western U.S., according to new data released Monday. Sixty-seven percent of Americans surveyed by Gallup living in the Northeast and West believe climate change is now occurring. 

Boaty McBoatface ’s maiden outing has made a major discovery about how climate change is causing rising sea levels. Scientists say that data collected from the yellow submarines's first expedition will help them build more accurate predictions in order to combat the problem.

Robot submarine, named after competition, will collect data from depths of Southern Ocean.

The British research submarine Boaty McBoatface has made an impressive debut in the scientific arena, discovering a significant link between Antarctic winds and rising sea temperatures on its maiden outing.

The unmanned submarine, whose moniker won a landslide victory in a public poll to name a $300 million British polar research ship, undertook its inaugural mission in April 2017.

Nearly half of young Americans say climate change is a "crisis"

Meanwhile, nearly 30 percent of those surveyed said economic inequality is a national crisis that also requires "urgent action.

Remote submersibles such as Boaty McBoatface will be essential: recent research showed that the undersea melting of Antarctic glaciers is more of a problem that had been thought. If the expedition discovers stability in the Thwaites glacier, it could assuage some of the worst fears of climate experts.

The first mission involving the autonomous submarine vehicle Autosub Long Range (better known as " Boaty McBoatface ") has for the first time Data collected from the expedition, published today in the scientific journal PNAS, will help climate scientists build more accurate predictions of the effects of

The task saw McBoatface travel 180 kilometers (112 miles) through mountainous underwater valleys in Antarctica, measuring the temperature, saltiness and turbulence in the depths of the Southern Ocean.

Its findings, published in the journal PNAS on Monday, revealed how increasingly strong winds in the region are causing turbulence deep within the sea, and as a result mixing warm water from middle levels with colder water in the abyss.

That process is causing the sea temperature to rise, which in turn is a significant contributor to rising sea levels, scientists behind the project said.

Antarctic winds are growing in strength due to the thinning of the ozone layer and the build-up of greenhouse gases, but their impact on the ocean has never been factored in to climate models.

The Boaty McBoatface saga is not the first time online polls have gone awry. Greenpeace launched a campaign to name a humpback whale in the South pacific in an attempt to keep them from being poached by the Japanese. The poll prompted a voting frenzy after Mr Splashy Pants was put forward

The British public voted in droves in 2016 to name the country's state-of-the-art new ship "RRS Boaty McBoatface," with the user-suggested name gathering 124,109 votes.

But despite the poll doing the impossible and uniting the country's electorate, the Natural Environment Research Council rejected the result and dubbed the ship RRS Sir David Attenborough after the renowned TV naturalist, in an effort to spare its blushes. The Boaty McBoatface name was instead given to a yellow submarine aboard the ship.

McBoatface's success on its first mission has helped shed light on a key process occurring in Antarctica for the first time, according to National Oceanography Centre.

"The data from Boaty McBoatface gave us a completely new way of looking at the deep ocean -- the path taken by Boaty created a spatial view of the turbulence near the seafloor," Eleanor Frajka-Williams of the center said in a statement.

"This study is a great example of how exciting new technology such as the unmanned submarine 'Boaty McBoatface' can be used along with ship-based measurements and cutting-edge ocean models to discover and explain previously unknown processes affecting heat transport within the ocean," added Povl Abrahamsen of the British Antarctic Survey.
