Drought in the northern hemisphere. What is the cause ?

Is the drought 2012 a prelude to an ominous era of water scarcity caused by global warming, as some might insist? It is indeed difficult to conjecture as even climate experts and scientists are divided on such matters. Climate patterns have been known to change dramatically over the centuries and droughts and famines have been with us for thousands of years, destroying communities and nations. Governments though must harness technology to provide solace to the millions suffering from such harsh climatic upheavals.


A drought in Florida is causing wild fires.

The summer of 2012 is turning out to be one of the worst in living memory for millions of people in the northern hemisphere, as a devastating drought ravages across thousands of hectares of farmland from the Korean peninsula in the east through China and India and on to the US Midwest.
While hundreds of farmers have committed suicide in recent months in several Indian states, there are fears of a catastrophe in North Korea because of the food shortage.


Here in Sri Lanka where I live and work, severe drought brought about by the delay in the north- west monsoon rains has severely affected Sri Lanka's agricultural sector threatening to destroy the paddy, vegetable and other food crop cultivations while the receding water levels in hydropower reservoirs have reduced power generation leading to possible power cuts. According to Sri Lanka's Minister of Agriculture Mahinda Yapa Abeywardena about 150,000 acres of cultivation lands are in danger of getting destroyed due to the drought in certain parts of the country, especially in the North Central, North and North Western provinces.

In several Midwestern states of the US, authorities are urging people not to light fireworks for the forthcoming Independence Day celebrations to limit the danger of fire. Comparisons are already being drawn to the drought of 1988 when nearly $80 billion worth of crops were lost following the failure of the rains in America.

Nearly a quarter of the United States is facing drought conditions and corn prices have soared by almost 30 per cent. The fact that the drought is affecting vast swathes of land in three of the world’s most significant economies — the US, China and India — which are also leading producers of agricultural crops means that there could be an acute shortage of food and a spurt in food prices.
North Korea, facing its worst drought in 50 years, is already posing a major challenge for the global community with a looming food shortage threatening millions. According to the United Nations, nearly two-thirds of the 24 million people in the country are facing chronic food shortages. The situation is equally grim in South Korea, where many regions are facing the worst drought since records began to be maintained more than a century ago.

In China, more than 4.25 million people — and an equally large number of livestock — are suffering from a shortage of drinking water in half a dozen provinces. In Hubei, about 800,000 people have been deprived of drinking water because of the drought.
The south-west monsoon, the lifeblood of India’s agriculture economy — which provides livelihood to 700 million people — has seen a disastrous start. The rains have failed across the sub-continent, leading to scarcity conditions. Met officials have also warned that the rains could fail during the second-half of the monsoon season (August and September) because of the El Nino effect, causing untold misery for millions.

Humans rarely experience phosphorus deficiency, and since meat and fish and supplementing with fresh and dried fruits.
In fact, you can recreate the intensity of such an activity.
The only real disagreement is that the paleo diet is that since early humans lived on this diet.

I seldom write responses, but I looked at some of the
responses on this page "Drought in the northern hemisphere. What is the cause ?".

I do have a couple of questions for you if you don't mind. Could it be simply me or do some of these comments come across like they are left by brain dead visitors? :-P And, if you are writing at other online sites, I would like to follow you. Would you list of every one of your social community sites like your Facebook page, twitter feed, or linkedin profile?

Hi there! I just wanted to ask if you ever have any issues with hackers?
My last blog (wordpress) was hacked and I ended up
losing months of hard work due to no backup.
Do you have any methods to protect against
hackers?
