Record drought in the Amazon

by SLKRR

In 2005, the Amazon region of Brazil confronted its worst drought in over a century.  Now in 2010, an even worse drought has struck.  The Rio Negro, the largest tributary of the Amazon above the city of Manaus, reached its lowest level since the beginning of record keeping in the 1800s.

Deforestation may not be the rain-forest's biggest enemy after all.  As weather patterns change due to global warming, more frequent and more severe droughts are punishing the Amazon basin.  Interspersed with these intense droughts are massive floods caused by record snow melt in the Andes - the Rio Negro reached its highest flood stage ever in 2009!  The annual rise and fall of the rivers that have been a part of Amazon life for centuries are being driven to greater and greater extremes.  How far before the balance is finally disrupted?

Texting on the Farm: Mobile Technology Provides Farmers with Useful Information in India

by NourishingthePlanet

According to the U.N. Population Division, over 70 percent of Indians live in rural areas and over half of all Indians are farmers. Yet access to technology and information in many areas is limited, meaning farmers are often left uninformed and at the mercy of erratic weather and disease and pest outbreaks. And even in good growing conditions, farmers may not have access to price information that could help them negotiate with buyers or decide which markets to bring their products to.

But across rural India, mobile phones are quickly becoming an indispensable tool for farmers, helping to shrink the information gap.

NCAR Predicts Possible Extreme Drought In Next Decades

by Something the Dog Said

They say in the Mountain West that whiskey is for drinking and water is for fighting. This simple saying shows how little water there really is and how critical it is a semi-arid environment like Colorado. There are more law practices that deal with water rights here than anywhere else in the United States. However what is the normal way of life for the Rockies might become the norm for large parts of the country and the world.

The National Center for Atmospheric Research (NCAR) has released a new study combining 22 climate models. These models are not looking at global warming, but rather the chance of increased drought world wide as temperatures climb. (Just a quick aside, you see real scientists aren’t falling for the "debate" meme that climate change deniers push. They know what is going on and have moved on to what will happen)

eKos: Return of the Dust Bowl

by FishOutofWater

Dust Storm, Texas Panhandle

Photo:Library of Congress Source: Red River Historian Desperation Road

In 2004 NASA's Siegfried Schubert discovered how ocean temperature anomalies caused the dust bowl drought in the Great Depression.

The study found cooler than normal tropical Pacific Ocean surface temperatures combined with warmer tropical Atlantic Ocean temperatures to create conditions in the atmosphere that turned America’s breadbasket into a dust bowl from 1931 to 1939. ...

These changes in sea surface temperatures created shifts in the large-scale weather patterns and low level winds that reduced the normal supply of moisture from the Gulf of Mexico and inhibited rainfall throughout the Great Plains.

The sea surface temperature anomaly patterns that caused the dust bowl drought have returned.

Flood or Drought? Pick yer poison

by LaughingPlanet

You've heard the term Feast or Famine?

It's time for a new version-

Drown or dehydrate.

Not quite as catchy, but scary relevant.

Have you noticed how many times we hear the term "100-year flood" these days? More often than once per hundred years, I'd wager.

Maybe you recall that the tragic mega-floods in Pakistan.

This is but the latest.

Thai Flooding Worst in Decades

Devastating floods spreading from northeastern Thailand  have left 17 people dead over the past two weeks as heavy rainfall has put entire villages underwater, destroyed crops and disrupted transportation and commerce.

Hell is coming: Drought in the age of global warming

by DWG

"Whiskey is for drinking; water is for fighting over."

-- Mark Twain (unverified)

Climate has always determined the availability of water resources. The human primate, proof of unintelligent design, has become a very potent force in depleting and destroying water resources. Together, it is recipe for disaster.

A study published in Nature last month showed that 80% of the human population lives in areas with severe threats to water security. A comprehensive review by Aiguo Dai at the National Center for Atmospheric Research (NCAR) paints a grim picture of the effects of climate change on water resources during this coming century. Drought will be the hallmark of the 21st century.

The detailed analysis concludes that warming temperatures associated with climate change will likely create increasingly dry conditions across much of the globe in the next 30 years, possibly reaching a scale in some regions by the end of the century that has rarely, if ever, been observed in modern times.

eKos: C02 Caused Climate Change Will Be Irreversible

by FishOutofWater

Climate change caused by anthropogenic CO2 emissions persists for over a thousand years and even short lived gases such as methane have long-term effects once they warm the deep ocean.

Carbon dioxide displays exceptional persistence that renders its warming nearly irreversible for more than 1,000 years..(edit).. dampening factors that slow temperature increase during periods of increasing concentration also slow the loss of energy from the Earth’s climate system if radiative forcing is reduced.

Open thread for night owls: Heat wave

by Meteor Blades

By Meteor Blades

From the beginning of the environmental movement, the biggest pushback has always been presented in terms of the economy. That's been true whether it's cod fishermen taking too big a catch in the Grand Banks, monocrop farmers sucking fossil water out of the Ogallala aquifer faster than it can be replenished, oil companies trashing indigenous land in Ecuador or loggers whacking massive segments of rain forest in the Amazon or Indonesia. When environmental advocates speak up about these matters, the first cry is invariably: what about the jobs? Not that jobs are unimportant. But too rarely is a case made for environmentally sound jobs and practices that can replace the ones causing the demolition of a particular eco-system, large or small.

The truth is that the environment and the economy are not two separate entities. They are inextricably intertwined with each other.

We're currently witness to another example of how climate change will have that intertwined effect. In Russia. Of course, what's happening there right now may only be weather, not a climate trend. We won't know for certain for a while yet. But the omens aren't good. And it's not just Moscow smog, a few dead people, ruined crops and some burned barns and homes. Here's what Isabel Gorst and Catherine Belton at the Financial Times had to say about it (subscription only):

Russia has begun counting the economic toll of the worst heatwave since records began as economists warned that the wildfires and disastrous summer harvest could wipe as much as 1 per cent off the country’s economic growth.

The record-breaking heatwave has destroyed grain crops across Russia, ruining close to a third of the country’s forecast harvest, while wildfires raging in the Moscow region have spread noxious smog over the capital, forcing businesses to close and many to flee the city.

Alexander Morozov, chief economist at HSBC, said the combined impact of the heatwave on agriculture and general economic activity could reduce Russia’s gross domestic product growth by about 1 per cent this year, a cost to the economy of about $15bn (€11bn, £9.5bn).

An estimated 10 to 13 per cent decline in Russian agricultural output this year would cost about 0.6 per cent of GDP, Mr Morozov said. Weather-related disruption to industrial production and the retail and services sector could account for a further 0.4 per cent decline.

Russia has been slowly climbing out of its worst recession since the late '90s, but Morozov says the impact of the drought and fires could stifle that recovery in the current quarter.

You don't have to live on a low-lying island or a coastal plain to be the target of bad effects from climate change. You don't have to be one of the millions who depend on drinking water from shrinking glaciers to be in the crosshairs. Anywhere. Everywhere.

At Daily Kos on this date in 2007:

There has to be an Orwell Corollary to Godwin's Law, one that says any discussion of today's Republican Party will invariably lead to comparisons with 1984.  That's the easy place to run when trying to sum up the miasma of misdirection and jingoism that passes for Republican speech.  But, damn it, when the candidates insist on treating the utterances of the Ministry of Truth as a textbook, what can you do?

Orwell

Freedom is Slavery

Giuliani

"Freedom is not a concept in which people can do anything they want, be anything they can be. Freedom is about authority. Freedom is about the willingness of every single human being to cede to lawful authority a great deal of discretion about what you do."

Ice, Fire, Deluge, Famine, Heat and a Definitive Trend: Act Today

by LaFeminista

Ice:

"Nobody can claim this was caused by global warming. On the other hand nobody can claim that it wasn't," Muenchow said

Fire:

"The mortality rate has doubled," said Andrei Seltsovsky, head of the city's health department. There were usually 360 to 380 deaths a day in the city, but "now that number is about 700".

Deluge:

The full scale of the tragedy engulfing Pakistan  is now emerging, with the United Nations saying today that the floods, which have entered their third week, have now affected 13.8 million people.

Famine:

The Diff animal herders who, by most estimates, have lost more than half of their livestock, say this year’s drought is not only worse than the one in 2005, but the worst in living memory.

eKos: The Permanent Dust Bowl

by FishOutofWater

Texas, the southern plains and the southwest will become a permanent dust bowl, if greenhouse gas emissions, causing climate change continue, unabated. In Texas, average temperatures 5 degrees Fahrenheit hotter, combined with permanent drought, will cause rivers and aquifers to dry up and crops to wither and die. Evaporation will far exceed precipitation. Parched cities will be hard pressed to find adequate water supplies for household and business needs. Conventional power generation methods will not have adequate water supplies for producing electricity.
