A long distance connection: polar climate affects trade wind strength in tropics
The impact of sea surface temperature variations in the tropical Pacific on global climate has long been recognized. For instance, the episodic warming of the tropical Pacific during El Niño events causes melt of sea ice in far-reaching parts of the Southern Ocean via its effect on the global atmospheric circulation. A new study, published this week in the journal Science Advances by an international team, demonstrates that the opposite pathway exists as well. (2020-11-20)

Using materials efficiently can substantially cut greenhouse gas emissions
Emissions from the production of materials like metals, minerals, woods and plastics more than doubled in 1995 - 2015, accounting for almost one-quarter of all greenhouse gas (GHG) emissions worldwide. Material efficiency needs to play a larger role in climate planning, a new report says. (2020-11-18)

Report: In retrospect, the burning of wood in district heating plants has resulted in climate saving
A new report from the University of Copenhagen shows that the burning of wood is significantly more climate friendly than coal and slightly more climate friendly than natural gas over the long run. For the first time, researchers quantified what the conversion of 10 Danish cogeneration plants from coal or natural gas to biomass has meant for their greenhouse gas emissions. (2020-11-17)

Drop in pandemic CO2 emissions previews world of electric vehicles
When the SF Bay Area mandated shelter-in-place March 16, it created a natural experiment for UC Berkeley's Ron Cohen, who had established an inexpensive pollution sensor network in local neighborhoods. The sensors showed carbon dioxide emissions plummeting 25% in the subsequent six weeks, mostly because of a 48% drop in traffic. Networks like this -- soon to be emplaced in Glasgow -- can track greenhouse gases and progress toward lowering them, including the impact of electric vehicles (2020-11-09)

Decrease in fossil-fuel CO2 emissions due to COVID-19 detected by atmospheric observations
Atmospheric observations at Hateruma Island, Japan, successfully detected the decrease in fossil-fuel CO2 emissions in China associated with the COVID-19 outbreak. The weather in Hateruma island is frequently influenced by the northwest monsoon travelling over China, which carries the emission signals of air pollutants. The observed ratios of CO2 and CH4 variabilities showed a significant decrease during February-March 2020, corresponding to about a 30% decrease in China's fossil-fuel CO2 emissions, according to a chemistry-transport model simulation. (2020-11-06)

Global food system emissions threaten achievement of climate change targets
Even if greenhouse gas emissions from fossil fuel use in the global food system were immediately halted, the remaining greenhouse gasses otherwise produced from global food production would make meeting the Paris Agreement's target of limiting temperature increases to 1.5° Celsius (C) above preindustrial levels very difficult, a new study reports. (2020-11-05)

Past is key to predicting future climate, scientists say
In a review paper published in the journal Science, a group of climate experts make the case for including paleoclimate data in the development of climate models.

Burning biomass fuels at home led to 32% of premature deaths from inhaling fine particles in China in 2014
The burning of biomass fuels such as wood and crop residues, which are often used for cooking and heating homes in rural China, contributed to 32% of an estimated 1,150,000 premature deaths caused by inhaling fine particle pollutants in China in 2014, according to a new study. Residential energy use of all types led to 67% of these premature deaths overall, the findings (2020-10-28)

Leaving more big fish in the sea reduces CO2 emissions
Leaving more big fish--like tuna, sharks, mackerel and swordfish--in the sea reduces the amount of carbon dioxide (CO2) released into the Earth's atmosphere.This is because when a fish dies in the ocean it sinks to the depths and sequestrates all the carbon it contains with it. This is a form of 'blue carbon'. Big fish are about 10 to 15 percent carbon. (2020-10-28)

Renewable energy targets can undermine sustainable intentions
Renewable energy targets (RETs) may be too blunt a tool for ensuring a sustainable future, according to University of Queensland-led research.

Winners and losers of energy transition
Drastically reducing greenhouse gas emissions in the electricity sector could have substantial economic and social impacts. Some regions might benefit more than others from new employment opportunities and from reduced air pollution, while others face threats to employment. Such a transition to renewable electricity thus risks creating new regional winners and losers. In a study published in Nature Communications, scientists from the University of Geneva (UNIGE) quantify regional impacts associated with Central European electricity targets. (2020-10-13)

Studying the sun as a star to understand stellar flares and exoplanets
New research shows that sunspots and other active regions can change the overall solar emissions. The sunspots cause some emissions to dim and others to brighten; the timing of the changes also varies between different types of emissions. This knowledge will help astronomers characterize the conditions of stars, which has important implications for finding exoplanets around those stars. (2020-10-12)

Fuels, not fire weather, control carbon emissions in boreal forest
A team led by Northern Arizona University found that the amount of carbon that burns in wildfires in western boreal forests depends more on available fuels than on fire weather such as drought conditions, temperature, or rain. (2020-10-12)

Researchers find increases in nitrous oxide emissions, outpacing global predictions
The term ''greenhouse gas'' is often used interchangeably with carbon dioxide, due to its prevalence in our atmosphere - more than 80 percent of all greenhouse gas emissions, estimates the Environmental Protection Agency. But another greenhouse gas, nitrous oxide (N2O), can have effects with far greater impact. And, according to a recent study, N2O emissions are increasing at a ''devastating'' rate, faster than predictions introduced by the Intergovernmental Panel on Climate Change. (2020-10-08)

UCI, others see agriculture as major source of increase in atmospheric nitrous oxide
In a new study in Nature, climate researchers have drawn the clearest lines yet around the problem of nitrous oxide in Earth's atmosphere. The potent greenhouse gas has both natural and human sources and, compared to CO2, is difficult to remove from the air, where it 'lives' for about 116 years. (2020-10-08)

Low-hanging fruit
For seven years now, the University of California system has been working hard to reduce its carbon emissions as part of its Carbon Neutrality Initiative. Each campus has been charged with finding ways to cut greenhouse gas emissions through a variety of measures -- such as increased energy efficiency and replacement of fossil fuel sources with renewable energy -- to meet milestones on the road to carbon neutrality.
