This Is Your Global Food Supply On Climate Change

OK, I’m going to go out on a limb and say that I think that this year’s climate extremes are linked to human-caused climate change. We might not really have the definitive answer on whether that is true for 20 years, but I would like nothing better than to be proven wrong about the linkage I’m making today. From a global food supply perspective, the effects of weather on 2012 food production is problematic no matter what its cause. As bad as it seems, it might just be a “shot over the bow” relative to what me might expect in the future.

Radical New Market-Based Campaign Aims to Make Forests More Valuable Alive than Dead

Over the past 2 decades, since the first Earth Summit in Rio de Janeiro, we have witnessed the launch of many initiatives to stop deforestation. Despite the good intentions of each approach tried, we have continued to lose an area the size of New York City every other day to deforestation. These activities account for 17% of global greenhouse gas emissions – more than the entire global transportation sector. Code REDD plans to harness the economic activities that create deforestation as tools to fight it.

Aflatoxin: A Toxic Potential of Climate Change

One of the most toxic and carcinogenic threats in the human food supply is a natural chemical called “aflatoxin”; the chance that it will contaminate a crop is enhanced by drought and/or insect damage – both conditions expected to be more common with the onset of climate change.

Map Shows Who Gets Screwed by Climate Change, Who Doesn't

In a new map illustrating climate vulnerability, it’s obvious which countries take the biggest hits, and are most susceptible to the effects of climate change. Developed by risk analysts Maplecroft, the map combines measures of the risk of certain global warming impacts, including storms, flooding, and droughts, with the social and financial ability of both […]

More Evidence of the Importance of Forests: They’re Even Bigger Carbon Sinks than Thought

Want to see clear connections between environmental degradation and economic struggles? Deforestation provides about as clear a picture as any example: the loss of ecological services (flood control, water and air purification, topsoil protection, etc.) have direct economic impacts ranging from disaster recovery costs to food prices to increased need for health care spending. And, […]

Damn! 400+ High Temperature Records Broken in US

It’s still mid-summer, and already over 400 individual maximum recorded temperature records have been broken in the US. Are you starting to sweat? Or were you already? Readers can use a handy feature on the National Oceanic and Atmospheric Administration’s (NOAA) website to check out just how hot this country is, and how many heat […]

Rising Temperatures Melting Away Global Food Security

By Lester R. Brown Heat waves clearly can destroy crop harvests. The world saw high heat decimate Russian wheat in 2010. Crop ecologists have found that each 1-degree-Celsius rise in temperature above the optimum can reduce grain harvests by 10 percent. But the indirect effects of higher temperatures on our food supply are no less […]
