Oyster-lovers beware … this delicacy could become a rarity

April 20, 2012 | 11:03 am | , Solutions Analyst

As 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.

Early spring not so sweet for sugar maples

Will warm springs and late frosts mean the end of sugar maples? 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.

Fewer cows and a shortage of flowers: How climate change impacts the Maasai in Kenya

April 10, 2012 | 11:47 am |

We visited a community of Maasai who are already suffering from impacts of climate change as droughts have become more frequent and severe. Normally the short rainy season occurs from late October through November, and the long rains go from March through June. We arrived just after the long rains had started. Even so, the local papers were again warning that there will be food shortages because of drier conditions.

As the climate warms, can trees move fast enough?

November 9, 2011 | 1:03 pm | , Science and Solutions Director

It’s not clear from this study why trees aren’t keeping pace with temperature change. Perhaps geographical boundaries, like coastlines, are getting in the way. Perhaps the species on the move are being out-competed in the new habitats. It’s even possible that tree seedlings are responding to climate change differently than adults.
