Fred Pearce writes about where we now stand with respect to the problem of climate change and what we can do to make a difference (Yale e360). This is a wide-ranging piece, full of worthy observations, and Fred is very much a realist. On the positive side he gives special attention to a recent report from Woods Hole Research which describes opportunities that are readily available in forestry and agriculture. That one is also an excellent report, very readable, and I have posted the link to it below.

They think the best price for viagra entire secret to outer beauty is skin lotions and intense workouts.

–From the Woods Hole report: “With appropriate action, the cumulative size of the forest sink could increase by 100 billion metric tons of carbon by the year 2100 — significantly larger than it is today.”

A new study finds evidence of better ways to preserve and enhance carbon storage in the soil. “Soil holds more than three times the carbon found in the atmosphere, yet its potential in reducing atmospheric carbon-dioxide levels and mitigating global warming is barely understood.” The story tells about certain farming practices that have demonstrated an ability to quickly and dramatically increase carbon content in the soil while continuing to produce food and fiber. (There is no better way I have heard of that will directly capture and remove CO2 from the atmosphere—or as cheap!)

A major study explains why the need to phase out natural gas emissions is just as urgent as those of oil and coal. One reason is that the amount of methane that escapes into the atmosphere has been drastically underestimated, with unburned methane being an extremely potent greenhouse gas. When added to the CO2 released from gas that is burned the combination would use up about one-third of the remaining carbon budget in Europe and many other parts of the Northern Hemisphere as well.

Vertical farming technology is ready to be rolled out. This is a nifty way to produce a number of fruit and vegetable crops indoors using a minimum amount of space. The food tastes good, has high quality and will be inexpensive. The developers are well-financed and already have plans for setting up operations near 500 large cities around the world. This is a fascinating story, and it is really happening.

A brief animation cleverly illustrates the correspondence between rising CO2 and rising global temperatures.
