In preparation for his upcoming fieldwork, Brown University research analyst Jay Dickson took 10,000 pictures of the inside of his freezer. He wasn’t investigating disappearing food or making sure the light went off when he closed the door. Dickson was making sure his new camera and timer would function properly for long periods in sub-freezing temperatures.
Due to man-made emissions, the CO2 content of the oceans has increased dramatically and is gradually acidifying the surface waters.
American Water has been awarded a research grant from the WateReuse Research Foundation to study the level of pathogen removal that occurs when ocean water is collected for desalination through sub-surface slant wells. The research will occur at the test slant well that is currently being constructed in Monterey County, California, by the company’s subsidiary, California American Water.
Reducing greenhouse gas (GHG) emissions, which result from the burning of fossil fuels, also reduces the incidence of health problems from particulate matter (PM) in these emissions.
Here’s another reason to pay close attention to microbes: Current climate models probably overestimate the amount of carbon that will be released from soil into the atmosphere as global temperatures rise, according to research from the US Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).
Scientists will have to find alternative explanations for a huge population collapse in Europe at the end of the Bronze Age as researchers prove definitively that climate change - commonly assumed to be responsible - could not have been the culprit.
"The Kyoto Protocol has not met the expectations. Currently, global emissions are at a more than 50% higher level than during the Protocol’s reference year, 1990. In the light of current trends and the annual increase in emissions being around 2.5% on average, global emissions have been assumed to double by 2030.
A vast majority of scientists believe that the Earth is warming at an unprecedented rate and that human activity is almost certainly the dominant cause. But on the topics of response and mitigation, there is far less consensus.
Reducing or eliminating tillage is one of the farming practices most frequently touted to improve carbon sequestration in soil. A new study by INRA and Arvalis-Institut du Végétal turns this paradigm on its head. This study, the result of a rigorous experiment conducted in the Ile-de-France region, shows that after a period of 41 years, three tillage methods led to similar carbon sequestration outcomes. However, variations were apparent over time based on climate conditions.
With the impact of climate change becoming more and more uncomfortably obvious, UCLA researchers are focused on making Los Angeles a sustainable model for other cities. At a climate change conference on campus today, UCLA researchers and other speakers are discussing the challenges facing cities around the world.
