Study: massive U.S. agriculture in the midwest has a climate cooling effect

From MIT: Intensive agriculture influences U.S. regional summer climate, study finds An increase in corn and soybean production in the Midwest may have led to cooler, wetter summers there. Scientists agree that changes in land use such as deforestation, and not just greenhouse gas emissions, can play a significant role altering the world’s climate systems. Now,…

Why did gas hydrates melt at the end of the last ice age?

GEOMAR researchers find links between sedimentation and methane seeps on the seafloor off the coast of Norway Large amounts of the greenhouse gas methane are locked up as solid gas hydrates in the continental slopes of ocean margins. Their stability depends on low temperatures and high pressure. However, other factors that influence gas hydrate stability…
