As societies around the world continue emitting heat-trapping greenhouse gases into the atmosphere, they face the consequence of sealevelrise. Since 1900, sealevels have increased 8 inches on average globally, and by 2100, sealevels will likely rise between 1 and 4 feet (Sweet et al.
There is a universe in which Hurricane Sandy didn’t create quite so much devastation back in 2012; where the waters, which surged deep into subway tunnels and left parts of New York City in the dark for days, left some parts of the tri-state area unscathed. And that universe, according to scientists, is one without climate change.
New research focused on the mechanisms and rates of how snow and ice is lost to the ocean from the land, along with studies of past climates offer new insights into how much sealevel may change in the coming years. Both approaches utilize computer models to further explore the relationship between sealevel and climate.
A century of greenhouse gasses heating up the atmosphere have eroded swaths of the Greenland ice sheet — frozen freshwater that holds back 23 feet of potential sealevelrise. For instance, an extreme melting event in 2012 led to the loss of 610 gigatons of ice, enough to fill Lake Eerie, and then some.
Intergovernmental Panel on Climate Change, a panel of the world’s top scientists, projected a two- to five-inch rise by 2100, depending on how much more carbon gets pumped into the atmosphere. The new research suggests that extreme temperatures could eventually trigger as much as 30 inches of sea-levelrise.
For example, recent research found that human-caused sea-levelrise increased the damages suffered when Hurricane Sandy hit the US East Coast in 2012 by $8.1 Another study found that climate change was responsible for $67 billion of damage caused by Hurricane Harvey, which hit Texas in 2017.
In 2012 scientists warned us that our oceans are dying but we did not respond. By 2012 dozens of studies made the case for anthropogenic climate change including a report from UNEP that warned that we are on the brink of a climate catastrophe. PricewaterhouseCoopers ( PwC ) issued a climate warning in 2012 and so did the World Bank.
Mountains in the Arctic in 2012: The region can expect an ice-free summer “at least once before 2050”, under even the most optimistic scenarios described in the latest IPCC report (image credit: duncan c , CC BY-NC 2.0
Bob Kopp, a co-author of the paper who researches climate change and sealevelrise at Rutgers University, said that talking about tipping points, as scary as they are, might not inspire people to do something about climate change. Thats because fear is an unreliable motivator.
Meanwhile, the melting of glaciers in Greenland are a leading contributor to sealevelrise that imperils coastal cities around the world via flooding. Tedesco said that the pace of melting in Greenland this year is on track to break a record set in 2012, when a net 562 gigatons of ice was lost.
The tide is turning against Louisiana’s proposed $2 billion Mississippi River sediment diversion project, that supporters say is needed to save the coast from rapid land loss due to subsidence, damage done by the oil and gas industry, extreme weather events, and sealevelrise quickened by climate change.
A 2012 study by the University of Plymouth in the U.K. predicted that a sea-levelrise of three to nine feet “will have a catastrophic effect on the human activities” in Lagos and other Nigerian coastal settlements. More than 24 million people live in this city on the Atlantic coast.
External costs include everything from pre-mature deaths due to air pollution to the sky-rocketing insurance costs for properties vulnerable to sealevelrise. I first visited Jacobson at Stanford University in 2012, when my college-touring son sat in on his popular Atmospheric Science class.
The WRI warned that we need to stop burning coal (Yang & Cui, 2012) and the IPCC synthesis report (2014) said that we must stop using fossil fuels. Failure to reduce atmospheric carbon puts us on track for sealevelrise, heat, drought and flooding that will cause widespread famine, disease and displacement.
Arctic sea ice extent averaged for September 2020 was 3.92 million square kilometers, the second lowest in the 42-year satellite record, behind only September 2012. Following the minimum seasonal extent, which occurred on September 15, ice growth quickly began along in the northern Beaufort, Chukchi, and East Siberian Seas.
Going further back, a North Sea oil boss gave him a donation in 2017 to help with his general election campaign. And going further back than that, he was among the Tory rebels who pushed for the government to stop backing onshore wind in 2012. Anne-Marie Trevelyan – Transport Secretary.
They sold the company in 2012 to a Singaporean sovereign wealth fund for $3.5 Another professor, the podcaster and author Michael Malice, claims that projections of sea-levelrise are “literally a religious belief.” fracking industry exploded in value. billion and landed themselves on the Forbes 400 list.
Human-caused climate change was responsible for $8 billion of the damage inflicted by Superstorm Sandy in 2012, new research published Tuesday in Nature found.
