Marine Economy Takes a Dive as Ocean Acidity Rises

Marine Economy Takes a Dive as Ocean Acidity Rises

The waters off the U.S. state of Alaska are some of the best fishing grounds anywhere, teeming with salmon and with shellfish such as crab. But a new study, funded by the U.S. National Oceanic and Atmospheric Administration(NOAA), says growing acidification of Alaska’s waters, particularly those off the southern coast, threatens the state’s whole e… Read More

New CO2 Satellite Sends First Data Back to Earth

New CO2 Satellite Sends First Data Back to Earth

NASA’s new carbon dioxide-monitoring satellite just opened its eyes for the first time. Based on the initial data its sending back to Earth, it appears to have 20/20 vision and scientists will soon have plenty more data to analyze. The satellite, dubbed the Orbiting Carbon Observatory-2, or OCO-2, was launched last month as part of an effort to be… Read More

Steady Increase in Flights Will Outweigh Carbon Cuts

Steady Increase in Flights Will Outweigh Carbon Cuts

percent of global carbon dioxide emissions coming from its aircraft. The problem is the speed at which aviation itself is growing. One aircraft builder believes the number of planes in service in 2011 will have doubled by 2031. Whatever the industry’s efforts to reduce its carbon emissions, they will be outweighed by the growth in air traffic, even… Read More

Indigenous Groups Give Tropical Forests a Carbon Boost

Indigenous Groups Give Tropical Forests a Carbon Boost

Any path forward to reduce the globe’s carbon emissions goes through tropical forests. They serve as a sink to sequester human emissions, but deforestation risks sending those assets up in smoke. A recent report argues that to avoid that outcome, indigenous communities should be involved in forest management. Currently deforestation and land use c… Read More

Using CO2 Emissions to Pump Oil May Help the Climate

Using CO2 Emissions to Pump Oil May Help the Climate

Called “carbon dioxide enhanced oil recovery,” the process works like this: CO2 emissions are captured from coal-fired power plants, then transported to old oil fields where production peaked long ago. By injecting the captured CO2 into existing oil wells that have been producing diminishing amounts of crude oil, hard-to-get crude oil will react wi… Read More

Roadside Land Offers Huge Carbon Storage Potential

Roadside Land Offers Huge Carbon Storage Potential

As you watch the miles roll by on family road trips this summer, look just behind the guard rails to see what some scientists believe is a significant untapped resource in the battle against climate change. The land alongside the 4 million miles of U.S. public roadways, already being maintained by federal, state, and local governments, could be pla… Read More

U.S. and China Lead the Way on Carbon Capture & Storage

U.S. and China Lead the Way on Carbon Capture & Storage

For years, the energy companies have been telling us not to worry. Yes, mounting carbon emissions threaten to heat up the world – but technology, particularly carbon capture and storage (CCS), will come to the rescue. The trouble is that there’s been plenty of talk about CCS and little action, with few projects being implemented on a large scale.… Read More

Genes Help Plants Handle Rising CO2 Levels

Genes Help Plants Handle Rising CO2 Levels

Biologists in the U.S. have identified the genetic machinery that tells a plant how to respond to more carbon dioxide caused by the burning of fossil fuels. Four genes from three different gene families together control the density of stomata, or breathing pores, on the foliage of the healthy plant. As carbon dioxide levels in the atmosphere rise, … Read More
