Arctic and Antarctic Sea Ice hit its lowest extent ever recorded by Satellites: Scientists

The ice floating on top of the Arctic Ocean and surrounding seas shrinks in a seasonal cycle from mid-March until mid-September

Washington, March 23, 2017: While Arctic Sea ice reached this year a record low wintertime maximum extent, sea ice around Antarctica also hit its lowest extent ever recorded by satellites at the end of summer in the Southern Hemisphere, scientists have said.

In February this year, the combined Arctic and Antarctic sea ice extent was at its lowest point since satellites began to continuously measure sea ice in 1979, said scientists at NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) in Boulder, Colorado.

Total polar sea ice covered 16.21 million square km, which is two million square km less than the average global minimum extent for 1981-2010 — the equivalent of having lost a chunk of sea ice larger than Mexico, the study said.

“It is tempting to say that the record low we are seeing this year is global warming finally catching up with Antarctica,” Walt Meier, a sea ice scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, said in a NASA release on Wednesday.

“However, this might just be an extreme case of pushing the envelope of year-to-year variability. We’ll need to have several more years of data to be able to say there has been a significant change in the trend,” Meier added.

As the Arctic temperatures drop in the autumn and winter, the ice cover grows again until it reaches its yearly maximum extent, typically in March.

The ring of sea ice around the Antarctic continent behaves in a similar manner, with the calendar flipped –it usually reaches its maximum in September and its minimum in February.

This winter, a combination of warmer-than-average temperatures, winds unfavourable to ice expansion, and a series of storms halted sea ice growth in the Arctic, the scientists said.

This year’s maximum extent, reached on March 7 at 14.42 million square kilometres, is 97,00 square kilometres below the previous record low, which occurred in 2015, and 1.22 million square kilometres smaller than the average maximum extent for 1981-2010, according to the scientists. (IANS)

Trump Administration Commits to Make Fossil Fuels Cleaner, Says Energy Secretary

Fossil fuel emissions have been cited by scientists as a major source of global warming

The Trump administration is committed to making fossil fuels cleaner rather than imposing “draconian” regulations on coal and oil, U.S. Energy Secretary Rick Perry said Thursday at an energy conference in Salt Lake City.

Perry previously said the administration wants to spend $500 million next year on fossil fuel research and development as demand plummets for coal and surges for natural gas.

“Instead of punishing fuels that produce emissions through regulation, we’re seeking to reduce those emissions by innovation,” Perry said at the conference. Fossil fuel emissions have been cited by scientists as a major source of global warming.

U.N. Secretary-General Antonio Guterres recently said the world must change how it fuels factories, vehicles and homes to limit future global warming.

Perry said the Trump administration has proven it can make energy cleaner, but he provided no details involving coal and other fossil fuels, other than the closing of old, inefficient coal-burning power plants and exporting increasing volumes of natural gas, an alternative to coal.

Department of Energy spokesman Dirk Vande Beek didn’t immediately return an email and voicemail seeking more details about Perry’s claim.

Perry pointed to an overall drop in emissions as proof of progress.

Greenhouse gas emissions dropped 13 percent from 2005 to 2017, according to the most recent report from the Environmental Protection Agency.

Lindsay Beebe of the Sierra Club in Utah said trying to make fossil fuels cleaner is misspent energy.

“I don’t know that it’s possible right now, but what is ready right now are renewables. Wind, solar and geothermal are commercially viable and at scale,” Beebe said.

The summit Thursday was briefly interrupted when 15 protesters took the stage to criticize the administration’s fixation on fossil fuels.

They said the misguided approach ignores climate change. Police then escorted them out.

After they left, Utah Gov. Gary Herbert, who sponsored the event, said he and other leaders appreciated the “youthful enthusiasm” but their call to immediately discard fossil fuels and shift entirely to renewable energy isn’t realistic.

“They would like us to quit by Friday and not take anything out of the ground,” Herbert said. “That obviously doesn’t work from a practical standpoint.”
