Oyster-lovers beware ... this delicacy could become a rarityAs an ardent foodie, I was concerned to see the results of a new study last week. The study warns that oyster production may decline due to rising carbon dioxide levels. Researchers found that higher levels of carbon dioxide in ocean water made the water more acidic and reduced the ability of oyster larvae to develop shells. This impaired the ability of oysters to grow at a normal pace, and led to a decline in yield.

No. But the scientists also found that yellow birch and American beech trees – which are slower to leaf out than sugar maples, even when temperatures are high – aren't as sensitive to frost. Meaning that as spring comes earlier in the year because of climate change, birch and beech may replace sugar maples in some locations.

March 2012: The warmest March since 1895In many ways it's been a beautiful spring, but something about it just hasn't been right. The cherry blossoms here in D.C. bloomed early, the bright pinks and reds of the azaleas at the Masters were missing, and it seems like allergy season is taking on a whole new meaning.

Fewer cows and a shortage of flowers: How climate change impacts the Maasai in KenyaWe visited a community of Maasai who are already suffering from impacts of climate change as droughts have become more frequent and severe.

Even so, the local papers were again warning that there will be food shortages because of drier conditions.

How the water gets up the mountain: Climate change in Yosemite Valley
My seven-year-old daughter had asked me in Yosemite how water gets up the mountain. Someday soon, we may find ourselves struggling with questions just as profound about how our national parks will survive climate change.
