The worsening climatic condition and unabated rise in global warming is giving sleepless nights for the global leaders and scientists across the world. The melting of glaciers in Antarctic and Arctic regions is affecting the climatic conditions badly.
In a bid to address the urgent issue, a group of international research team from the University of Washington has begun an experiment to study the pattern of ice degradation in the Arctic region. The researchers at the university have placed sensors under the ice sheets in the Beaufort Sea to understand the pattern of ice melting and track them.
According to the researchers, the ice sheets melt most during the summers and continue till the month of September.
“We’re really trying to resolve the physics over the course of an entire melt season,” Craig Lee, who led the experiment, said.
Lee is an oceanographer at the University of Washington’s Applied Physics Laboratory.
The project, aimed at understanding the impact of weather on Arctic’s ice pattern, was funded by the US Office of Naval Research. The study was conducted by the research team led by oceanographer Craig Lee. His team included researchers and scientists from Cambridge University, Yale University, Laboratoire d’Oceanographie de Villefranche, Naval Research Laboratory, Woods Hole Oceanographic Institution, Korean Polar Research Institute and the British Antarctic Survey.
The scientists have also found that the hitting of waves at the shores also influence badly on these ice sheets, leading to their degradation. They explain, the strong waves hit the ice sheets with massive amount of energy which leads to their further breaking.
According to the research team, the installed sensors will help in measuring and keeping a record of different factors related to ocean, ice sheets and atmosphere in the Arctic region.
‘Climatic change result of human intervention’
A study published in the April 6 issue of Climate Dynamics has found that global warming is not a result of natural temperature changes, as commonly conceived, but is due to human intervention.
El Niño effect
Another study published in January this year in the journal Nature Climate Change has warned that the El Nino weather condition linked to Droughts in Australia and flooding in the Americas are likely to double with treacherous climate change in the next century.
The El Niño Southern Oscillation (ESNO) effect occurs when the sea surface temperatures exceed 28C in the normally cold waters of the eastern equatorial Pacific, where the climate is usually dry. It is noteworthy, the El Niño was previously defined as a pattern of unusually warm water stretching across the surface of eastern equatorial Pacific. The effect was said to be occurring every 3-7 years, causing catastrophic natural disasters. The strongest El Nino ever recorded occurred in 1997-98 resulting in the hottest year on record, killing as many as 23,000 people worldwide, causing damage estimated at between £22bn and £28bn.
UN calls for immediate action on climate change
Observing the hazardous conditions, the United Nations has warned against the rising levels of greenhouse gases and urged the world leaders for greater global efforts to tackle the severe issue.
According to a draft report by UN experts, delaying action on worsening climatic condition will only add to the costs and reduce the opportunities to deal with it.
The United Nations’ final draft report ‘Intergovernmental Panel on Climate Change’ says that global warming will continue to increase unless the countries do not shift their attention immediately.
Expressing serious concerns over the burning issue, the United Nations said that the national policies and global efforts aimed at curbing climate change are inefficient in dealing with the issue. It says level of Carbon Dioxide and other greenhouse gases that are warming the planet has grown by 2.2% per year on average in 2000-2010 – almost twice as high as in 1970-2000.
