Small volcanic eruptions might eject more of an atmosphere-cooling gas into Earth's upper atmosphere than previously thought, potentially contributing to the recent slowdown in global warming, according to a new study.
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).
"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.
If you want to see into the future, you have to understand the past. An international consortium of researchers under the auspices of the University of Bonn has drilled deposits on the bed of Lake Van (Eastern Turkey) which provide unique insights into the last 600,000 years. The samples reveal that the climate has done its fair share of mischief-making in the past. Furthermore, there have been numerous earthquakes and volcanic eruptions.
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.
Arctic sea ice has diminished significantly in recent decades, particularly in summer. Researchers from Norway and China have collaborated on developing an autonomous buoy with instruments that can more precisely measure the optical properties of Arctic sea ice while also taking measurements of ice thickness and temperature.
The tremendous value of diverse ecosystems is often invisible to the naked eye. The Research Council of Norway is encouraging research activities that draw closer connections between climate and biodiversity.
