Global warming 'will make our winters colder' - Climate Change - Environment - The Inde... - 0 views

  • Climate scientists believe they have found evidence to suggest that the loss of floating Arctic sea ice in the Barents and Kara seas north of Scandinavia can affect the global circulation of air currents and lead to bitterly cold winds blowing for extended periods in winter over Central Asia and Europe, including the UK.
  • the cooling effect is unlikely to last beyond this century
  • Rising global temperatures will eventually cancel out any localised cooling caused by loss of Arctic sea ice, although they said it is not possible to predict when this will happen.

This year's El Nino will be the strongest in 18 years, WMO says - Technology & Science ... - 0 views

  • The current El Nino weather phenomenon is expected to peak between October and January and could turn into one of the strongest on record, experts from the World Meteorological Organization said at a news conference on Tuesday.
  • waters in the east-central Pacific Ocean are likely to be more than 2 degrees hotter than average,

  • "The truth is we don't know what will happen. Will the two patterns reinforce each other? Will they cancel each other? Are they going to act in sequence? Are they going to be regional? We really don't know,"
  • it is still unclear how global warming is affected by the frequency or magnitude of El Nino events.

Looming megadroughts in western US would make current drought look minor | Environment ... - 0 views

  • California is in its sixth year of drought, which was barely dented by rains brought by the El Niño climate event and sparked a range of water restrictions in the state. But warming temperatures and uncertain rainfall mean that if more isn’t done to slow climate change, droughts lasting 35 years are likely to blight western states by the end of the century, according to the study, published in Science Advances.
  • Such a megadrought would impose “unprecedented stress on the limited water resources”
  • the study predicts a 70% chance of a megadrought by the end of the century,

Blaming natural disasters on climate change will backfire. - 0 views

  • Thus, the migration in response to the severe and prolonged drought exacerbated a number of the factors often cited as contributing to the unrest, which include unemployment, corruption, and rampant inequality. The conflict literature supports the idea that rapid demographic change encourages instability. Whether it was a primary or substantial factor is impossible to know, but drought can lead to devastating consequences when coupled with preexisting acute vulnerability, caused by poor policies and unsustainable land use practices in Syria’s case and perpetuated by the slow and ineffective response of the Assad regime [emphasis added].
  • suggests that an unprecedented drought accentuated frustration with the Assad regime and led to migration from rural to urban areas.
  • While climate change will probably increase the number and intensity of heavy showers, leading to more frequent landslides, intensive logging and government negligence in permitting new construction in these areas cause the real disasters.

  • While global warming probably accentuated the torrential rains, it was actually policy failures that allowed heavy rains to cause the flood and human suffering: Over the past two decades, the city government has systematically disregarded basic principles of ecology and urban planning by building structures in flood plains and marshlands.
  • Climate change is often going to be the domino that falls. But that does not mean we can ignore the rest of the dominos in the row.

  • IN 2007 a Russian-led polar expedition, descending through the icy waters of the Arctic Ocean in a Mir submarine, planted a titanium Russian tricolour on the sea bed 4km (2.5 miles) beneath the North Pole. “The Arctic has always been Russian,
  • Denmark has staked a claim to the North Pole, too. On December 15th it said that, under the UN Convention on the Law of the Sea (UNCLOS), some 900,000 square kilometres of the Arctic Ocean north of Greenland belongs to it (Greenland is a self-governing part of Denmark).

  • perhaps a quarter of its gas.
  • Drilling for oil and gas there is extremely expensive, and falling oil prices have made the economics of Arctic energy even less favourable. This gives would-be prospectors an interest in co-operating, not in adding to the risks and costs.
  • The melting of the summer sea ice has also opened up trade routes between Asia and Europe via the top of the world; 71 cargo ships plied the north-east passage last summer, up from 46 in 2012

Greenhouse Gases - 0 views

  • As a measure of this efficiency, greenhouse gases are often assigned a value for "Global Warming Potential" (GWP). This value is simply a comparison of the efficiency of a gas relative to CO2 over a time span of 100 years. Therefore a gas with a GWP of 20 is 20 times more efficient at retaining heat than CO2 over a 100 year time period.

Louisiana five years after BP oil spill: 'It's not going back to normal no time soon' |... - 0 views

  • the restaurants are still empty, FOR SALE signs are increasing in store windows, people are still moving away, and this marina on Pointe a la Hache – once packed most afternoons with oystermen bringing in their catch on their small boats, high school kids earning a few bucks unloading the sacks, and 18-wheelers backed up by the dozen to carry them away – is completely devoid of life, save one man, 69-year-old Clarence Duplessis, who cleans his boat to pass the time.
  • While some phenomena in the Gulf – people getting sick, fishing nets coming back empty – are hard to definitively pin on BP – experts say the signs of ecological and economic loss that followed the spill are deeply concerning for the future of the Gulf. Meanwhile, BP has pushed back hard on the notion that the effects of its disaster are much to worry about, spending millions on PR and commercials to convince Gulf residents everything will be OK.
  • the Gulf is recovering faster than expected,” Geoff Morrell, a BP senior vice-president for communications, said in an email.

  • depleted oyster beds could be due to a variety of factors other than the spill – including the divergence of fresh water from the Mississippi into coastal marshes.
  • Anxiety seems to be the most prevalent emotion in this part of the state. Every cough and every cancer screening, every paltry catch and shrimp missing an eye raises the question – is it BP?
  • oystermen say their catches plummeted after the spill, and have only been getting worse.
  • In total, BP has so far spent $27bn in economic claims, its disaster response efforts, fines to various governments, and cleanup and restoration programs.
  • The company has been sued by dozens of entities since the Deepwater Horizon spill, including state, local and federal governments, and individuals claiming economic loss. It has so far agreed to pay $4.5 billion in fines and plead guilty to a host of criminal charges, including felony manslaughter.
  • total just under $10 billion to businesses suffering because of the spill, but has fought the interpretation of that agreement at every step, claiming it it too easy for businesses without any proof of the spill directly causing damage to their bottom lines to win claims. The Supreme Court recently rejected BP’s bid to hear their challenge to that case.
  • the average claim for his association’s members ranged from a couple thousand to about $25,000. That, he says, is paltry when compared to the years-long recovery he sees ahead of him.
  • “My Facebook feed is filled with my friends’ pictures of crabs with no eyes, shrimp and crawfish with one eye or things missing,” Misty Fisher, 24, said.
  • Southern Louisiana’s economy hasn’t only been ravaged by the spill, but by multiple hurricanes and the ever-encroaching coastline: Louisiana is losing a football field worth of wetlands every 48 minutes thanks to a combination of global warming and a history of oil companies failing to remediate the canals they dredge for pipelines and oil and gas production.
  • Fisher and her fellow waitresses say they all know people who are sick – respiratory infections, breast cancers, constant headaches – which they blame on the spill.
