Dr. David Suzuki – How to Feed the World as the Planet Warms

Calculating farming’s contribution to greenhouse gas emissions is difficult, but experts agree that feeding the world’s people has tremendous climate and environmental impacts. Estimates of global emissions from farms range widely. The U.S. Environmental Protection Agency puts them at 24 percent, including deforestation, making agriculture the second-largest emitter after heat and electricity. Agriculture contributes to global warming in a number of ways. …

Plants’ ability to adapt could change conventional wisdom on climate change, U of M study finds

Plants speed up their respiratory metabolism as temperatures rise, leading to a long-held concern that as climate warms the elevated carbon release from a ramped-up metabolism could flip global forests from a long-term carbon sink to a carbon source, further accelerating climate change. However, a new University of Minnesota study with more than 1,000 young trees has found that plants …

Ken Browne – Researchers just discovered a massive body of water under China’s biggest desert

The Tarim basin in Xinjiang, China is a valley the size of Venezuela; bigger than California, New Mexico and Florida put together. On the surface it is home to Taklimakan, China’s biggest desert, but deep beneath lies a hidden ‘ocean’ that is thought to contain up to ten times more water than all the Great Lakes combined, storing more carbon …

Andrea Germanos – Battered By Drought, Forests Lose Ability to Fend Off Climate Change

Forests play an important role as “carbon sinks” by absorbing and storing CO2 emissions, but a new study finds that that droughts—expected to become more frequent with climate change—deal that climate-buffering power a blow. The findings, published this week in the journal Science, show that forests don’t recover as quickly after a drought as had been previously thought, indicating a …

Organic Farming Changes Agriculture from a Huge Carbon Source to a Carbon-DESTROYER

Approximately 35% of global greenhouse gases (GHGs) come from agriculture. Some argues that human can reverse global worming by sequestering several hundred billion tons of excess CO2 through regenerative, organic farming, ranching and land use. Increasing the soil’s organic content will not only fix carbon and reduce emissions, it will also improve the soil’s ability to retain water and nutrients …

Organic farming can reverse the agriculture ecosystem from a carbon source to a carbon sink
