Patna: Bihar, which faced a drought-like situation till last week, is now bracing up to handle floods in hundreds of its villages, officials said on Saturday. The water level is rising in several rivers following heavy rain in the state and the catchment areas of Nepal since Thursday, threatening hundreds of villages, they added.

Be it Kosi, Gandak, Ganga, Bagmati and other rivers, the water level has increased after heavy rain in the last few days. Thousands of people have started fleeing their homes in panic, a state disaster management department official said. A high alert has been declared in vulnerable districts, particularly bordering Nepal, by the water resources department. It has been done in view of the water entering hundreds of villages and the rising water level in several rivers, an official of the department said.

Meteorological department officials here said north Bihar districts received a record 200 mm of rainfall on Thursday and 175 mm on Friday. According to officials, the rising water level in the rivers is putting pressure on the embankments at several places. Hundreds of people were fleeing their homes in Supaul, Muzaffarpur, Saharsa, Madhepura, Bhagalpur, Munger and Purnea districts.

The Bihar government has alerted engineers and asked them to keep a 24-hour vigil. In 2008, over three million people were rendered homeless in Bihar when the Kosi river breached its bank upstream in Nepal and changed course. It was said to be the worst flood in the state in the last 50 years.

Greenland Is Melting

If all the ice covering the world’s largest island were to thaw, sea levels would rise roughly 6 meters

  • Greenland is slowly melting
  • This melting adds roughly 1 millimetre of water per year to global sea levels
  • This can mean huge floods in coming years

Like a bowling ball on a skating rink, the black geodesic sphere of the East Greenland Ice-Core Project’s communal living space stands out against the endless white nothingness of the Greenland ice sheet.

 

Iceberg melting can cause huge floods in coming years.
Iceberg melting can cause huge floods in coming years.

But the real action at East GRIP is under the surface. Researchers are drilling through more than 2.5 kilometres of ice, down to the bedrock below. The ice is sliding fast — for a glacier — toward the sea. Scientists here want to know why. The answer may hold clues to the future of the world’s coastal cities.

Greenland is melting. As it melts, it adds roughly 1 millimetre of water per year to global sea levels. And the pace of melting is quickening.

If all the ice covering the world’s largest island were to thaw, sea levels would rise roughly 6 meters. Scientists don’t know how fast, or how likely, that is to happen. East GRIP is looking for evidence to inform both those questions.

The answers are a matter of growing urgency. The seas are rising faster. And the same processes at work on Greenland’s glaciers at the top of the world could send vast sections of Antarctica’s ice sheet into the sea as well, raising ocean levels even further.

The Arctic is warming twice as fast as the rest of the planet. Scientists studying the rapid changes gather in the small Greenland town of Kangerlussuaq, a former U.S. military base built during World War II. Through the Cold War, this outpost supplied remote radar sites watching a nuclear attack coming over the pole.

These days, military transport planes fly scientists and their equipment across 1,000 kilometres of Arctic ice to East GRIP. They make research possible here and at other far-flung scientific outposts on the vast Greenland ice sheet.

Departing from Kangerlussuaq, VOA visited East GRIP and other remote corners of Greenland with the 109th Airlift Wing of the U.S. Air National Guard for a firsthand look at science in action at the leading edge of climate change. VOA
