From Kansas to China's Sichuan province, farmers treat their fields with phosphorus-rich fertilizer to increase the yield of their crops. What happens next, however, receives relatively little attention. Large amounts of this resource are lost from farm fields, through soil erosion and runoff, and down swirling toilets, through our urine and feces. Although seemingly mundane, this process cannot continue indefinitely.

The level of the most important heat-trapping gas in the atmosphere, carbon dioxide, has passed a long-feared milestone, scientists reported Friday, reaching a concentration not seen on the earth for millions of years.

Scientific instruments showed that the gas had reached an average daily level above 400 parts per million — just an odometer moment in one sense, but also a sobering reminder that decades of efforts to bring human-produced emissions under control are faltering.

Chinese researchers have identified the origins of the novel H7N9 influenza virus

asianscientist.com - April 29, 2013

In March 2013, a novel H7N9 influenza virus was identified in China as the source of a flu-like disease in humans. A group of scientists, led by Professor Chen Hualan of the National Avian Influenza Reference Laboratory at the Harbin Veterinary Research Institute, investigated the origins of this novel H7N9 influenza virus.

“We suggest that strong measures, such as continued surveillance of avian and human hosts, control of animal movement, shutdown of live poultry markets, and culling of poultry in affected areas, should be taken during this initial stage of virus prevalence to prevent a possible pandemic. Additionally, it is also imperative to evaluate the pathogenicity and transmissibility of these H7N9 viruses, and to develop effective vaccines and antiviral drugs against so as to reduce their adverse effects upon human health,” say the authors.

A swarm of the Red Locusts passes through the Madagascar town of Sakaraha, on April 27, 2013 (AFP, Bilal Tarabey) Experts estimate there are currently 100 swarms across Madagascar, made up of about 500 billion ravenous locusts

ANTANANARIVO — For three quarters of an hour a giant swarm of locusts streams across the sky above southwest Madagascar.

Along National Route Seven, normally an artery for tourists enjoying breathtaking views of the island's vast open spaces, a 15 kilometre long (nine mile) swarm clouds the sky.

Travellers today see little more than a natural disaster in progress -- a plague of locusts which has already destroyed half of the Indian Ocean island's crops.

Full Planet, Empty Plates: The New Geopolitics of Food Scarcity

Chapter 2. The Ecology of Population Growth

by Lester R. Brown

Throughout most of human existence, population growth has been so slow as to be imperceptible within a single generation. Reaching a global population of 1 billion in 1804 required the entire time since modern humans appeared on the scene. To add the second billion, it took until 1927, just over a century. Thirty-three years later, in 1960, world population reached 3 billion. Then the pace sped up, as we added another billion every 13 years or so until we hit 7 billion in late 2011.

Greek youth unemployment shot to a record 64 percent in February, underscoring the dire state of the recession-hit economy despite signs of improving business sentiment.

Repeated doses of austerity under international bailouts have almost tripled Greece's jobless rate since its debt crisis began in 2009, weighing on an economy in its sixth year of recession.

Overall unemployment has risen to an all-time high of 27 percent, data showed on Thursday, while joblessness in the 15-to-24 age group jumped to 64.2 percent in February from 59.3 percent in January.

Robert Lucas, one of the greatest macroeconomists of his generation, and his followers are “making ancient and basic analytical errors all over the place”. Harvard's Robert Barro, another towering figure in the discipline, is “making truly boneheaded arguments”. The past 30 years of macroeconomics training at American and British universities were a “costly waste of time”.

Crisis-mapping technology has emerged in the past five years as a tool to help humanitarian organizations deliver assistance to victims of civil conflicts and natural disasters. Crisis-mapping platforms display eyewitness reports submitted via e-mail, text message, and social media. The reports are then plotted on interactive maps, creating a geospatial record of events in real time.

Honeybees are vital for pollinating crops - a job that would be very costly without them

bbc.co.uk - April 29, 2013

The European Commission will restrict the use of pesticides linked to bee deaths by researchers, despite a split among EU states on the issue.

There is great concern across Europe about the collapse of bee populations.

Neonicotinoid chemicals in pesticides are believed to harm bees and the European Commission says they should be restricted to crops not attractive to bees and other pollinators.

But many farmers and crop experts argue that there is insufficient data.

The thermometers got it right. The Earth is warming, another study is reporting.

Climate scientists recognize that changes in weather observation stations' immediate surroundings -- such as neighboring trees being replaced by heat-absorbing concrete -- can eventually throw data from such stations into question.

But now, a new study directed by a researcher at the National Oceanic and Atmospheric Administration that recreates climate history without the use of land-based observation systems shows the same thing that thermometers have been reporting.

"This shows that global warming over land is real," said Gilbert Compo, a scientist at NOAA's Cooperative Institute for Research in Environmental Sciences at the University of Colorado.

Perhaps the biggest shortcoming of solar and wind power is their intermittency. In locations like Hawaii, where I live, wind and solar power are already competitive on price. My fossil-fuel supplied electricity typically costs above 40 cents a kilowatt-hour, and wind and solar power can compete with that. But since they can’t supply power that is available on demand (firm power) they must be backed up by power sources that can provide power when the sun isn’t shining and the wind isn’t blowing.
