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

Chapter 7. Grain Yields Starting to Plateau

by Lester R. Brown

From the beginning of agriculture until the mid-twentieth century, growth in the world grain harvest came almost entirely from expanding the cultivated area. Rises in land productivity were too slow to be visible within a single generation. It is only within the last 60 years or so that rising yields have replaced area expansion as the principal source of growth in world grain production.

Climate change is occurring 10 to 100 times faster than in the past and ecosystems will find it hard to adjust

CLICK HERE - RESEARCH REPORT - Abstract - Changes in Ecologically Critical Terrestrial Climate Conditions

scientificamerican.com - by Anne C. Mulkern and ClimateWire - August 2, 2013

The climate is changing at a pace that's far faster than anything seen in 65 million years, a report out of Stanford University says.

The amount of global temperature increase and the short time over which it's occurred create a change in velocity that outstrips previous periods of warming or cooling, the scientists said in research published in today's Science.

If global temperatures rise 1.5 degrees Celsius over the next century, the rate will be about 10 times faster than what's been seen before, said Christopher Field, one of the scientists on the study. Keeping the temperature increase that small will require aggressive mitigation, he said.

Sea levels, as we know, are incredibly sensitive to rises in global temperatures. A study released earlier this month revealed that the increase of a mere degree celsius could lead global sea levels to rise by as much as two meters. But according to a new study published in the Proceedings of the National Academy of Sciences, the implications are especially grim for the US. At the current rate of carbon emissions, over 1,700 cities, including New York, Boston and Miami, will be “locked in” by greenhouse gas emissions by this century’s end.

Rt Hon David Cameron, Tuesday, November 10 2009

Speech (excerpt):

. . . I want to extend and deepen the argument I made in my party conference speech this year, that the size, scope and role of government in Britain has reached a point where it is now inhibiting, not advancing the progressive aims of reducing poverty, fighting inequality, and increasing general well-being. Indeed there is a worrying paradox that because of its effect on personal and social responsibility, the recent growth of the state has promoted not social solidarity, but selfishness and individualism.

But I also want to argue that just because big government has helped atomise our society, it doesn't follow that smaller government would automatically bring us together again. . .

BOOK REVIEW

How Much of This Do We Use Up Every Year?

Written by: BILL GATES

. . . I mean everything that can be consumed on
Earth: plants, animals, all of it. And by "we" of
course I mean people.

It's such a big question that many people wouldn't even know where to start.

But if you care about understanding the impact that humans are having on the Earth, and what that means for our future, it's a crucial question. Vaclav Smil sets out to answer it in his book Harvesting the Biosphere: What We Have Taken From Nature.

(Reuters) - An oil spill that has blackened beaches at a Thai holiday island was having an extreme impact on tourism and could spread to the coast of the mainland and affect the fishing industry, officials and an environmental group said on Tuesday.

Tourists were pouring off the island of Koh Samet, 230 km (142 miles) southeast of Bangkok, while soldiers and volunteers in white bio-hazard suits struggled to clear black oily sludge off the white sand.

"We're working to move visitors to other locations if they want to move," Tourism Minister Somsak Phurisisak told reporters.

"I'm very concerned, I didn't think this spill would impact tourism in such an extreme way."

The world installed 31,100 megawatts of solar photovoltaics (PV) in 2012—an all-time annual high that pushed global PV capacity above 100,000 megawatts. There is now enough PV operating to meet the household electricity needs of nearly 70 million people at the European level of use. While PV production has become increasingly concentrated in one country—China—the number of countries installing PV is growing rapidly.

Increasing temperatures in the Arctic region are reducing sea ice cover and increasing the possibility of methane leaching from the sea bed

bbc.co.uk - by Matt McGrath - July 24, 2013

Scientists say that the release of large amounts of methane from thawing permafrost in the Arctic could have huge economic impacts for the world.

The researchers estimate that the climate effects of the release of this gas could cost $60 trillion (£39 trillion), roughly the size of the global economy in 2012.

The impacts are most likely to be felt in developing countries they say.

The research has been published in the journal Nature.

Very recently, a publication appeared by perhaps the world's best-known hurricane scientist, Dr. Kerry Emanuel of MIT. Dr. Emanuel combined global computer simulations with more regional simulations to look into the future at the evolution of storms. What he found was surprising.

. . . In our era of electronic communications, we’ve come to expect that important innovations will spread quickly. Plenty do: think of in-vitro fertilization, genomics, and communications technologies themselves. But there’s an equally long list of vital innovations that have failed to catch on. The puzzle is why.

Increasing global emissions of carbon dioxide (CO2), a heat-trapping gas, are pushing the world into dangerous territory, closing the window of time to avert the worst consequences of higher temperatures, such as melting ice and rising seas. Since the dawn of the Industrial Revolution, carbon emissions from burning fossil fuels have grown exponentially. Despite wide agreement by governments on the need to limit emissions, the rate of increase ratcheted up from less than 1 percent each year in the 1990s to almost 3 percent annually in the first decade of this century.

Among the many strange mantras repeated by climate change deniers is the claim that even in an overheated, climate-altered planet, animals and plants will still survive by adapting to global warming. . .

. . . However, their rate of change turns out to be painfully slow, according to a study by Professor John Wiens of the University of Arizona. . . The results, published online in the journal Ecology Letters, show that most land animals will not be able to evolve quickly enough to adapt to the dramatically warmer climate expected by 2100.

Thousands of barrels of tar-sands oil have been burbling up into forest areas for at least six weeks in Cold Lake, Alberta, and it seems that nobody knows how to staunch the flow.

An underground oil blowout at a big tar-sands operation run by Canadian Natural Resources Ltd. has caused spills at four different sites over the past few months. . .

Media and others have been blocked from visiting the sites, but the Toronto Star obtained documents and photographs about the ongoing disaster from a government scientist involved in the cleanup, who spoke to the reporter on condition of anonymity.
