UN report sees $1.45 tn global warming cost: media

Feb 28, 2014
Global warming will reduce the world's crop production by up to two percent every decade and wreak $1.45 trillion of economic damage by the end of this century, according to a draft UN report

Global warming will reduce the world's crop production by up to two percent every decade and wreak $1.45 trillion of economic damage by the end of this century, according to a draft UN report, Japanese media said Friday.

The document is the second volume in a long-awaited trilogy by the Intergovernmental Panel on Climate Change (IPCC), a Nobel-winning group of scientists, which is set to be issued next month after a five-day meeting in Japan, the Yomiuri Shimbun reported.

The trilogy is the IPCC's first great overview of the causes and effects of global warming, and options for dealing with it, since 2007.

According to the draft, if rise by 2.5 degrees Celsius (4.5 Fahrenheit), the world's aggregated gross domestic production will fall by 0.2 to 2 percent, the mass circulation paper said.

That would translate into 15 trillion yen to 148 trillion yen ($147 billion to $1.45 trillion) in economic losses, calculated against the world's total GDP in 2012, it said.

The planet's crop production will decline by up to two percent every decade as rainfall patterns shift and droughts batter farmland, even as demand for food rises a projected 14 percent, it said.

Other effects from global warming include the loss of land to rising sea levels, forcing hundreds of millions of people to migrate from coastal areas, with the most vulnerable regions including East, South and Southeast Asia, it said.

The draft report, which will be reviewed in the March 25-29 meeting in Yokohama, calls for mitigation measures to reduce the vulnerability of environments to such as flood protection projects and research on the prevention of infectious diseases, it said.

In the first volume of the trilogy, the IPCC said it was more certain than ever that humans were the cause of and predicted temperatures would rise another 0.3 to 4.8 degrees Celsius (0.5-8.6 degrees Fahrenheit) this century.

Heatwaves, floods, droughts and rising seas are among the threats that will intensify through warming, it said in in the report released in September in Stockholm.

UN climate chief Christiana Figueres said the report was "an alarm-clock moment for the world".

"To steer humanity out of the high danger zone, governments must step up immediate climate action and craft an agreement in 2015" against greenhouse gases, she said at the time.

The IPCC has delivered four previous assessments in its 25-year history.

Each edition has sounded an ever-louder siren to warn that temperatures are rising and the risk to the climate system is accentuating.

The projections for this century are based on computer models of trends in heat-trapping greenhouse gas emissions, especially from coal, oil and gas, which provide the backbone of energy supply today.

A Japanese environment ministry official declined to comment on the report, citing IPCC's request to keep it behind closed doors until the final version is approved in Yokohama.

The UN is a bloated, bureaucratic, overly political organization. Just the fact the report comes from the UN makes it suspect.

we can increase the yeild and nutrition of our food by increasing the CO2. Just saying.

Yes Agomemnon. CO2 is essential for photosynthesis and is thus plant food which may explain the increase in crop yields over recent years. More CO2 means the stomata on the leaves don't have to open so much and the opening of the stomata is the main way that plants lose water. Thus more CO2 means increasing drought resistance and the greening of deserts which has already been observed. We may be coming to the end of a 5 million year long CO2 drought. The UN is run by all sorts of people with all sorts of hidden agendas and has no credibility at all.

How much percentage royalty of these $1.4tn the authors of the study are seeking? I searched their report but it is obscure on the exact number.

Simple equation calibrated by average global temperature data through 1990 and actual sunspot numbers through 2012 'predicts' average global temperature trend through 2013 within 0.013 K.

And yet the rightwing under-achievers will deny, deny and continue to deny the obvious environmental impact mankind has on global scales. Global warming, Acidic Oceans, Toxic Food, Mountain top removal, Acid Rain, Mercury, Arctic Ice melt, Massive species extinction, etc, ..., etc. It's sick. And you rightwing nut cases (The large body of the walking, talking, brain stems (nothing on-top the brain stem, but a brain stem non-the-less)) still what to make-believe that global warming isn't happening! All I can figure, is you like poking your brain-stem into oil soaked beach sand to hide whatever human compassion for your planet from your jack-off boot lick buddies.

WARNING: There is a well funded movement by oil, gas and tobacco firms to sew doubt about the science behind global warming. While there are legitimate skeptics debating specific items in the body of science behind global warming. Anyone stating that climate scientists are doing this to make money, or that they've missed obvious facts like the solar cycle, or that they have some clever theory that nullifies 50,000 published papers over the past 30 years on climate science is either a paid troll of these firms or someone whose ideological bias has clouded their judgment.

As the article states. Real climate scientists have been sounding this alarm for over 25 years and the evidence continues to mount that humans are driving rapid climate change and the speed of that change is both unprecedented and posses significant risks for millions of people.

But the temperatures aren't rising. They've been falling for more than a dozen years.
