World Bank Warns 4˚C Climate Change Could Devastate Global Economy

World Bank Warns 4˚C Climate Change Could Devastate Global Economy | Coastal management | Scoop.it

A four degree Celsius could decimate agriculture, cause global health problems and would result in a very different world economy.

 

The World Bank warned Sunday that if climate change isn't stopped or slowed down, the global economy will suffer greatly. The report, titled "Turn Down the Heat," envisions a world that is warmer by an average of 4 degrees Celsius (7.2 degrees Fahrenheit). According to Jim Yong Kim, president of the World Bank, the report is meant to "shock the world into action." A global temperature increase like one estimated by the World Bank would lead to "the inundation of coastal cities; increasing risks for food production, potentially leading to higher malnutrition rates; many dry regions becoming dryer, wet regions wetter; unprecedented heat waves in many regions," water scarcity, and more natural disasters.

 

The organization chose to analyze a four-degree increase because that's the worst-case scenario envisioned by the Intergovernmental Panel on Climate Change—and it could be a reality as early as 2060. Though the report makes no specific financial estimates, it says a warming world would wreak havoc on farming, overload countries' health systems, and would disproportionately affect the poor. It would push up food prices, make 35 percent of farmland in sub-Saharan Africa unsuitable for agriculture, and would extend the ranges of certain diseases.

 

Rachel Kyte, the World Bank's vice president for the sustainable development network, says the organization commissioned the report to help governments and businesses understand the urgency of the problem as countries deal with a global recession.

 

Many countries should be looking into infrastructure upgrades that use clean energy, developing nations should consider encouraging urban growth with sea level rise in mind, and considering the long-term health of their economies instead of focusing on quick fixes. "The short term political cycles sometimes fit uneasily with long-term decision making," Kyte says. "We hope this paper makes it more difficult for policy makers to ignore the science. The science is unequivocal."

Elijah Startin's insight:

This topic states that studies show that the Earth is becoming 4 degrees celsius warmer. And by 2060 climate change will become a reality.

Greenland’s icecap - once thought stable - is losing stability due to melting at an accelerating pace

Greenland’s icecap - once thought stable - is losing stability due to melting at an accelerating pace | Coastal management | Scoop.it

The Greenland ice sheet is the largest terrestrial ice mass in the Northern hemisphere. A recent study in Nature Climate Change by Shfaqat Khan from the Technical University of Denmark and colleagues indicates that the ice sheet could be melting faster than previously thought. This would mean Greenland’s contribution to sea level rise has been under-estimated (once again!), and oceanographers may need to think again about their projections.

 

The scientists used more than 30 years of surface elevation measurements of the entire ice sheet to discover that overall loss is accelerating. Previous studies had identified melting of glaciers in the island’s south-east and north-west, but the assumption had been that the ice sheet to the north-east was stable.

 

The report says: “It was stable, at least until about 2003. Then higher air temperatures set up the process of so-called dynamic thinning. Ice sheets melt every Arctic summer, under the impact of extended sunshine, but the slush on the glaciers tends to freeze again with the return of the cold and the dark, and since under historic conditions glaciers move at the proverbial glacial pace, the loss of ice is normally very slow.”

 

The new research by the Danish-led team considers changes linked to the 600 kilometer-long Zachariae ice stream in the north-east, using satellite measurements. It has retreated by some 20 kilometers in the last DECADE, whereas Sermeq Kujalleq has retreated about 35 kms in 150 years. The Zachariae stream drains around one-sixth of the Greenland ice sheet, and because warmer summers have meant significantly less sea ice in recent years, icebergs have more easily broken off and floated away, which means that the ice stream can move faster. “North-east Greenland is very cold. It used to be considered the last stable part of the Greenland ice sheet,” said one of the team, Michael Bevis of Ohio State University in the US, in an interview with the Climate News Network.


The scientists used a GPS network to calculate the loss of ice. Glacial ice presses down on the bedrock below it: when the ice melts, the bedrock rises in response to the drop in pressure, and sophisticated satellite measurements help scientists put a figure on the loss of ice. They calculate that between April 2003 and April 2012, the region was losing ice at the rate of 10 billion tons a year.

This report shows that the icecaps are melting due to the earth's climate getting warmer. This means that as the ice melts the sea levels rise.

There she, very slowly, goes.

 

Well humanity, this environment which we evolved into was fun.  Will we survive this new one we've produced through our economic and social activity?

I don't know.

 

But what I do know, is that the old normal is gone, thanks largely to the conservatives who wanted to preserve the old normal.

 

A silly brain type at best, who can't accept reality for what it actually is, and thus, leads us all into misery, pain and destruction as a result of their willful and unacknowledged unwillful ignorance.

 

Think about it.
