Thirty Year Timeout for Global Warming

Let me get this right. We have a cooling event without cause and we must be prepared to discount it as significant for thirty years. I am trying to imagine any other field of human endeavor that would accept such a specious argument. It in fact boggles the mind. The heart of good science is to acknowledge the data and ask where it takes you.

In this case, the data is flowing strongly against the proposed theory and its expected data structure. The data is not waffling anymore as it did the previous several years. It has completely undone all the previous warming and is still trending downward.

Attempting to preserve a pet theory by giving it a thirty year time out is unbelievable. It might have been better to do what most other scientists have done by either becoming silent or beating a hasty retreat.

In 2007, the sea ice melt had entered terminal breakup if the seven year temperature regime was maintained. The temperature reversal was almost immediate and is continuing. We have made some progress to understanding what drives this reversal and I can assure you it has zip to do with human meddling.

My response was to recognize the new data and explain its meaning. It really is that easy. My continuing concern is that the community has a long lead time in getting data interpretations out into the hands of the public. It took a minimal understanding of theory to recognize that present trends meant an ice free 2012. NASA and others were already into temperature reversal data before their related stories came out. This means that I am generally reading out of date news stories on climate subjects.

Today we are continuing to suffer through a cold miserable winter comparable to the low end on the averages for the past fifty years. I also have no reason to anticipate anything else for the next few years.

The only variable able to show significance is solar sunspot activity and it continues to be very quiet. If it got active tomorrow, the lag time will still be a couple of years.

Global Warming: On Hold?

Michael Reilly, Discovery News

March 2, 2009 -- For those who have endured this winter's frigid temperatures and today's heavy snowstorm in the Northeast, the concept of
global warming may seem, well, almost wishful.

But climate is known to be variable -- a cold winter, or a few strung together doesn't mean the planet is cooling. Still, according to a new study, global warming may have hit a speed bump and could go into hiding for decades.

Earth's climate continues to confound scientists. Following a 30-year trend of
warming, global temperatures have flatlined since 2001 despite rising greenhouse gas concentrations, and a heat surplus that should have cranked up the planetary thermostat.

"This is nothing like anything we've seen since 1950," Kyle Swanson of the University of Wisconsin-Milwaukee said. "Cooling events since then had firm causes, like eruptions or large-magnitude
La Ninas. This current cooling doesn't have one."

Instead, Swanson and colleague Anastasios Tsonis think a series of climate processes have aligned, conspiring to chill the climate. In 1997 and 1998, the tropical Pacific Ocean warmed rapidly in what Swanson called a "super El Nino event." It sent a shock wave through the oceans and atmosphere, jarring their circulation patterns into unison.

How does this square with temperature records from 2005-2007, by some measurements among the warmest years on record? When added up with the other four years since 2001, Swanson said the overall trend is flat, even though temperatures should have gone up by 0.2 degrees Centigrade (0.36 degrees Fahrenheit) during that time.

The discrepancy gets to the heart of one of the toughest problems in climate science -- identifying the difference between natural variability (like the occasional March snowstorm) from
human-induced change.

But just what's causing the cooling is a mystery. Sinking water currents in the north Atlantic Ocean could be sucking heat down into the depths. Or an overabundance of tropical clouds may be reflecting more of the sun's energy than usual back out into space.

"It is possible that a fraction of the most recent rapid warming since the 1970s was due to a free variation in climate," Isaac Held of the
National Oceanic and Atmospheric Administration in Princeton, New Jersey wrote in an email to Discovery News. "Suggesting that the warming might possibly slow down or even stagnate for a few years before rapid warming commences again."

Swanson thinks the trend could continue for up to 30 years. But he warned that it's just a hiccup, and that humans' penchant for spewing
greenhouse gases will certainly come back to haunt us.

"When the climate kicks back out of this state, we'll have explosive warming," Swanson said. "Thirty years of greenhouse gas radiative forcing will still be there and then bang, the warming will return and be very aggressive."

Global Drought Tightens

Eric deCarbonnel has done us a favour and assembled in a rough and ready manner, the apparent numbers developing in the global agricultural scene. He is an alarmist here but one gets the inescapable sense that it will be very difficult to cover shortfalls this year and that there will be plenty of pain to spread around.

I would speculate that the globe is readjusting back to normal climatic conditions with the typical disruptive lag biting everyone’s tail. We may well test our reserves this year, but that should be followed by a strong replenishing cycle world wide. This is going to be needed.

I also do not see quite were he is getting some of his more alarming numbers from, and perhaps we should just leave them alone for now. A lot of these droughts are localized within large growing regions and simply do not apply to the region as a whole. Some of these droughts are due to break as has happened in California. In fact, the evidence indicates that weather bands have shifted south and that suggests to me that the southern USA is about to have its drought broken as spring returns.

In spite of that, I think that the press will have a lot to talk about this year on the weather and drought front. However, if the global drought breaks everywhere it will be pleasant news for a change

Why am I so confident? I think that the present drought conditions are lagging results from the drop in global temperatures brought about by the Pacific Decadal Oscillation reversal and that global weather is rebounding back to conditions that stood twenty years ago. The impact of this is weather disruption that should now be ending as the tropical weather system re-expands again.

Monday, February 9, 2009
After reading about the droughts in two major agricultural countries, China and Argentina, I decided to research the extent other food producing nations were also experiencing droughts. This project ended up taking a lot longer than I thought. 2009 looks to be a humanitarian disaster around much of the world.

To understand the depth of the food Catastrophe that faces the world this year, consider the graphic below depicting countries by USD value of their agricultural output, as of 2006.

Now, consider the same graphic with the countries experiencing droughts highlighted.

https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEirXo1-dksOxDOF3c3lBygEs4_1E9n1JrWlZb3g9RAKGhGYhnxuNtyJKcRrJP3Xdm2CttxgtF9p4bH4sPLsTMgW8anzKCCYksINZYrs7p7VOSXqiajTw0HvGTBPm9kfOoXgaNU2kYegg4fa/s1600-h/Countries_by_agricultural_output%5B1%5D-747806.png

The countries that make up two thirds of the world’s agricultural output are experiencing drought conditions. Whether you watch a video of the drought in China, Australia, Africa, South America, or the US, the scene will be the same: misery, ruined crop, and dying cattle.

ChinaThe drought in Northern China, the worst in 50 years, is worsening, and summer harvest is now threatened. The area of affected crops has expanded to 161 million mu (was 141 million last week), and 4.37 million people and 2.1 million livestock are facing drinking water shortage. The scarcity of rain in some parts of the north and central provinces is the worst in recorded history.

The drought which started in November threatens over half the wheat crop in eight provinces - Hebei, Shanxi, Anhui, Jiangsu, Henan, Shandong, Shaanxi and Gansu.HenanChina's largest crop producing province, Henan, has issued the highest-level drought warning. Henan has received an average rainfall of 10.5 millimeters since November 2008, almost 80 percent less than in the same period in the previous years. The Henan drought, which began in November, is the most severe since 1951.

AnhuiAnhui Province issued a red drought alert, with more than 60 percent of the crops north of the Huaihe River plagued by a major drought.

ShanxiShanxi Province was put on orange drought alert on Jan. 21, with one million people and 160,000 heads of livestock are facing water shortage.

JiangsuJiangsu province has already lost over one fifth of the wheat crops affected by drought. Local agricultural departments are diverting water from nearby rivers in an emergency effort to save the rest.

HebeiOver 100 million cubic meters of water has been channeled in from outside the province to fight Hebei’s drought.
Shaanxi1.34 million acres of crops across the bone-dry Shanxi province are affected by the worsening drought.

ShandongSince last November, Shandong province has experienced 73 percent less rain than the same period in previous years, with little rainfall forecast for the future.

Relief efforts are under way. The Chinese government has allocated 86.7 billion yuan (about $12.69 billion) to drought-hit areas. Authorities have also resorted to cloud-seeding, and some areas received a sprinkling of rain after clouds were hit with 2,392 rockets and 409 cannon shells loaded with chemicals. However, there is a limit to what can be done in the face of such widespread water shortage.

As I have previously written,
China is facing hyperinflation, and this record drought will make things worse. China produces 18% of the world's grain each year.

AustraliaAustralia has been experiencing an unrelenting drought since 2004, and 41 percent of Australia's agriculture continues to suffer from the worst drought in 117 years of record-keeping. The drought has been so severe that rivers stopped flowing, lakes turned toxic, and farmers abandoned their land in frustration:

A) The Murray River stopped flowing at its terminal point, and its mouth has closed up.B) Australia’s lower lakes are evaporating, and they are now a meter (3.2 feet) below sea level. If these lakes evaporate any further, the soil and the mud system below the water is going to be exposed to the air. The mud will then acidify, releasing sulfuric acid and a whole range of heavy metals. After this occurs, those lower lake systems will essentially become a toxic swamp which will never be able to be recovered. The Australian government's only options to prevent this are to allow salt water in, creating a dead sea, or to pray for rain.

For some reason, the debate over climate change is essentially over in Australia.The United States

California
California is facing its worst drought in recorded history. The drought is predicted to be the most severe in modern times, worse than those in 1977 and 1991. Thousands of acres of row crops already have been fallowed, with more to follow. The snowpack in the Northern Sierra, home to some of the state's most important reservoirs, proved to be just 49 percent of average. Water agencies throughout the state are scrambling to adopt conservation mandates.

Texas
The Texan drought is reaching historic proportion. Dry conditions near Austin and San Antonio have been exceeded only once before—the drought of 1917-18. 88 percent of Texas is experiencing abnormally dry conditions, and 18 percent of the state is in either extreme or exceptional drought conditions. The drought areas have been expanding almost every month. Conditions in Texas are so bad cattle are keeling over in parched pastures and dying. Lack of rainfall has left pastures barren, and cattle producers have resorted to feeding animals hay. Irreversible damage has been done to winter wheat crops in Texas. Both short and long-term forecasts don't call for much rain at all, which means the Texas drought is set to get worse.

Augusta Region (Georgia, South Carolina, North Carolina)

The Augusta region has been suffering from a worsening two year drought. Augusta’s rainfall deficit is already approaching 2 inches so far in 2009, with January being the driest since 1989.

Florida

Florida has been hard hit by winter drought, damaging crops, and half of state is in some level of a drought.
La Niña likely to make matters worse

Enough water a couple of degrees cooler than normal has accumulated in the eastern part of the Pacific to create a La Niña, a weather pattern expected to linger until at least the spring. La Niña generally means dry weather for Southern states, which is exactly what the US doesn’t need right now.

South America

Argentina

The worst drought in half a century has turned Argentina's once-fertile soil to dust and pushed the country into a state of emergency. Cow carcasses litter the prairie fields, and sun-scorched soy plants wither under the South American summer sun. Argentina's food production is set to go down a minimum of 50 percent, maybe more. The country's wheat yield for 2009 will be 8.7 million metric tons, down from 16.3 million in 2008. Concern with domestic shortages (domestic wheat consumption being approximately 6.7 million metric ton), Argentina has granted no new export applications since mid January
.Brazil

Brazil has cut its outlook for the crops and will do so again after assessing damage to plants from desiccation in drought-stricken regions. Brazil is the world's second-biggest exporter of soybeans and third-largest for corn.
Brazil's numbers for corn harvesting:

Harvested in 2008: 58.7 million tons
January 8 forecast: 52.3 million tons
February 6 forecast: 50.3 metric tons (optimistic)
Harvested in 2009: ???

Paraguay

Severe drought affecting Paraguay's economy has pushed the government to declare agricultural emergency. Crops that have direct impact on cattle food are ruined, and the soy plantations have been almost totally lost in some areas.

UruguayUruguay declared an "agriculture emergency" last month, due to the worst drought in decades which is threatening crops, livestock and the provision of fresh produce.The a worsening drought is pushing up food and beverage costs causing Uruguay's consumer prices to rise at the fastest annual pace in more than four years in January.

BoliviaThere hasn’t been a drop of rain in Bolivia in nearly a year. Cattle dying, crops ruined, etc…ChileThe severe drought affecting Chile has caused an agricultural emergency in 50 rural districts, and large sectors of the economy are concerned about possible electricity rationing in March. The countries woes stem from the "La Niña" climate phenomenon which has over half of Chile dangling by a thread: persistently cold water in the Pacific ocean along with high atmospheric pressure are preventing rain-bearing fronts from entering central and southern areas of the country. As a result, the water levels at hydroelectric dams and other reservoirs are at all-time lows.

Horn of Africa

Africa faces food shortages and famine. Food production across the Horn of Africa has suffered because of the lack of rainfall. Also, half the agricultural soil has lost nutrients necessary to grow plant, and the declining soil fertility across Africa is exacerbating drought related crop losses.

KenyaKenya is the worst hit nation in the region, having been without rainfall for 18 months. Kenya needs to import food to bridge a shortfall and keep 10 million of its people from starvation. Kenya’s drought suffering neighbors will be of little help.

TanzaniaA poor harvest due to drought has prompted Tanzania to stop issuing food export permits. Tanzania has also intensified security at the border posts to monitor and prevent the export of food. There are 240,000 people in need of immediate relief food in Tanzania.BurundiCrops in the north of Burundi have withered, leaving the tiny East African country facing a severe food shortage

Uganda
Severe drought in northeastern Uganda's Karamoja region has the left the country on the brink of a humanitarian catastrophe. The dry conditions and acute food shortages, which have left Karamoja near starvation, are unlikely to improve before October when the next harvest is due.

South Africa

South Africa faces a potential crop shortage after wheat farmers in the eastern part of the Free State grain belt said they were likely to produce their lowest crop in 30 years this year. South Africans are "extremely angry" that food prices continue to rise.Other African nations suffering from drought in 2009 are: Malawi, Zambia, Swaziland, Somalia, Zimbabwe, Mozambique, Tunisia, Angola, and Ethiopia.

Middle East and Central Asia

The Middle East and Central Asia are suffering from the worst droughts in recent history, and food grain production has dropped to some of the lowest levels in decades. Total wheat production in the wider drought-affected region is currently estimated to have declined by at least 22 percent in 2009. Owing to the drought's severity and region-wide scope, irrigation supplies from reservoirs, rivers, and groundwater have been critically reduced. Major reservoirs in Turkey, Iran, Iraq, and Syria are all at low levels requiring restrictions on usage. Given the severity of crop losses in the region, a major shortage of planting seed for the 2010 crop is expected.

IraqIn Iraq during the winter grain growing period, there was essentially no measurable rainfall in many regions, and large swaths of rain-fed fields across northern Iraq simply went unplanted. These primarily rain-fed regions in northern Iraq are described as an agricultural disaster area this year, with wheat production falling 80-98 percent from normal levels. The USDA estimates total wheat production in Iraq in 2009 at 1.3 million tons, down 45 percent from last year.

SyriaSyria is experienced its worst drought in the past 18 years, and the USDA estimates total wheat production in Syria in 2009 at 2.0 million tons, down 50 percent from last year. Last summer, the taps ran dry in many neighborhoods of Damascus and residents of the capital city were forced to buy water on the black market. The severe lack of rain this winter has exacerbated the problem.

AfghanistanLack of rainfall has led Afghanistan to the worst drought conditions in the past 10 years. The USDA estimates 2008/09 wheat production in Afghanistan at 1.5 million tons, down 2.3 million or 60 percent from last year. Afghanistan normally produces 3.5-4.0 million tons of wheat annually.

JordanJordan's persistent drought has grown worse, with almost no rain falling on the kingdom this year. The Jordanian government has stopped pumping water to farms to preserve the water for drinking purposes.

Other Middle Eastern and Central Asian nations suffering from drought in 2009 are: The Palestinian Territories, Lebanon, Israel, Bangladesh, Myanmar, India, Tajikistan, Turkmenistan, Thailand, Nepal, Pakistan, Turkey, Kyrgyzstan, Uzbekistan, Cyprus, and Iran.

Lack of credit will worsen food shortage

A lack of credit for farmers curbed their ability to buy seeds and fertilizers in 2008/2009 and will limit production around the world. The effects of droughts worldwide will also be amplified by the smaller amount of seeds and fertilizers used to grow crops.

Low commodity prices will worsen food shortage

The low prices at the end of 2008 discouraged the planting of new crops in 2009. In Kansas for example, farmers seeded nine million acres, the smallest planting for half a century. Wheat plantings this year are down about 4 million acres across the US and about 1.1 million acres in Canada. So even discounting drought related losses, the US, Canada, and other food producing nations are facing lower agricultural output in 2009.
Europe will not make up for the food shortfall
Europe, the only big agricultural region relatively unaffected by drought, is set for a big drop in food production. Due to the combination of a late plantings, poorer soil conditions, reduced inputs, and light rainfall, Europe’s agricultural output is likely to fall by 10 to 15 percent.

Stocks of foodstuff are dangerously low

Low stocks of foodstuff make the world’s falling agriculture output particularly worrisome. The combined averaged of the ending stock levels of the major trading countries of Australia, Canada, United States, and the European Union have been declining steadily in the last few years:

2002-2005: 47.4 million tons
2007: 37.6 million tons
2008: 27.4 million tons

These inventory numbers are dangerously low, especially considering the horrifying possibility that
China’s 60 million tons of grain reserves doesn't actually exists.

Global food Catastrophe

The world is heading for a drop in agricultural production of 20 to 40 percent, depending on the severity and length of the current global droughts. Food producing nations are imposing food export restrictions. Food prices will soar, and, in poor countries with food deficits, millions will starve.

The deflation debate should end now

The droughts plaguing the world’s biggest agricultural regions should end the debate about deflation in 2009. The demand for agricultural commodities is relatively immune to developments in the business cycles (at least compared to that of energy or base metals), and, with a 20 to 40 percent decline in world production,
already rising food prices are headed significantly higher.

In fact, agricultural commodities NEED to head higher and soon, to prevent even greater food shortages and famine. The price of wheat, corn, soybeans, etc must rise to a level which encourages the planting of every available acre with the best possible fertilizers. Otherwise, if food prices stay at their current levels, production will continue to fall, sentencing millions more to starvation.

Competitive currency appreciation

Some observers are anticipating “competitive currency devaluations” in addition to deflation for 2009 (nations devalue their currencies to help their export sector). The coming global food shortage makes this highly unlikely. Depreciating their currency in the current environment will produce the unwanted consequence of boosting exports—of food. Even with export restrictions like those in China, currency depreciation would cause the outflow of significant quantities of grain via the black market.

Instead of “competitive currency devaluations”, spiking food prices will likely cause competitive currency appreciation in 2009.
Foreign exchange reserves exist for just this type of emergency. Central banks around the world will lower domestic food prices by either directly selling off their reserves to appreciate their currencies or by using them to purchase grain on the world market.

Appreciating a currency is the fastest way to control food inflation. A more valuable currency allows a nation to monopolize more global resources (ie: the overvalued dollar allows the US to consume 25% of the world's oil despite having only 4% of the world's population). If China were to selloff its US reserves, its enormous population would start sucking up the world's food supply like the US has been doing with oil.

On the flip side, when a nation appreciates its currency and starts consuming more of the world’s resources, it leaves less for everyone else. So when china appreciates the yuan, food shortages worldwide will increase and prices everywhere else will jump upwards. As there is nothing that breeds social unrest like soaring food prices, nations around the world, from Russia, to the EU, to Saudi Arabia, to India, will sell off their foreign reserves to appreciate their currencies and reduce the cost of food imports. In response to this, China will sell even more of its reserves and so on. That is competitive currency appreciation.When faced with competitive currency appreciation, you do NOT want to be the world’s reserve currency. The dollar is likely to do very poorly as central banks liquidate trillions in US holdings to buy food and appreciate their currencies.
