We currently consider terrestrial vegetation, including forests, to be a sink, sequestering carbon dioxide (CO2) from the atmosphere. The vegetation absorbs CO2 during the process of photosynthesis throughout the growing season. This sink is responsible for the absorption of 30 per cent of our anthropogenic emissions, that is, the greenhouse-gas (GHG) emissions due to the combustion of fossil fuels related to human activity.
Global warming is now threatening this important service. Plants need to absorb CO2 to achieve photosynthesis, allowing them to produce carbohydrates for their development. But to keep their tissues alive and functional, plants must also respire, that is, release CO2 into the atmosphere; the difference between the CO2 absorbed for photosynthesis and that released by respiration represents the CO2 sink of the terrestrial vegetation.
The Woods Hole Black History Month Committee is celebrating 40 years in Woods Hole in 2021. Four virtual events are planned during February as part of Black History Month. All events are free, however, those interested in participating must register in advance on the Woods Hole Diversity Initiative website, where further information is available about each of the events.
The national theme for Black History Month is âThe Black Family: Representation, Identity, and Diversity.â
The celebration will begin at noon Thursday, February 4, with a panel discussion titled â40 Years of Black History Month in Woods Hole: The Journey and the Future.â The discussion will be moderated by Ambrose Jearld Jr., a charter member of the committee. Mr. Jearld retired in 2016 as a fisheries biologist after a 38-year NOAA Fisheries career at the Northeast Fisheries Science Center in Woods Hole.
North Alabama must reject leaders who refuse to grow

When I was born in Huntsville in 1959, the city was booming and in transition from being the Watercress Capital of the World to be the Rocket City. This did not happen by accident or without vision and, yes, political pull. The city has been shepherded by men such as Bob Jones, Ronnie Flippo, Bud Cramer, John Sparkman, Howell Heflin and now Richard Shelby. I don’t agree with the politics of some on this list, and some of these men certainly shared the sin of racist politics, but all shared and pursued a vision for North Alabama that has helped to shape it in a positive way despite this.
