Fishes Contribute Roughly 1.65 Billion Tons of Carbon in Feces and Other Matter Annually
Scientists have little understanding of the role fishes play in the global carbon cycle linked to climate change, but a Rutgers-led study found that carbon in feces, respiration and other excretions from fishes – roughly 1.65 billion tons annually – make up about 16 percent of the total carbon that sinks below the ocean’s upper layers.

Limiting warming to 2 C requires emissions reductions 80% above Paris Agreement targets
Even if all countries meet their Paris Agreement goals for reducing emissions, Earth has only a 5% chance of staying below 2 C warming this century, a 2017 study showed. But reductions about 80% more ambitious, or an average of 1.8% drop in emissions per year rather than 1% per year, would be enough to meet the agreement’s stated goal, analysis shows.

NSU Research Scientist Part of Team Studying Impact of Rising Sea Temperatures on Marine Life
Global warming. Climate change. Coral bleaching. These are a few issues that are negatively impacting our marine world. And now you can add underwater heatwaves to the list – something an NSU Researcher is studying.
Important Climate Change Mystery Solved by Scientists
Scientists have resolved a key climate change mystery, showing that the annual global temperature today is the warmest of the past 10,000 years – contrary to recent research, according to a Rutgers-led study in the journal Nature. The long-standing mystery is called the “Holocene temperature conundrum,” with some skeptics contending that climate model predictions of future warming must be wrong. The scientists say their findings will challenge long-held views on the temperature history in the Holocene era, which began about 12,000 years ago.
WashU Experts: The first 100 Biden/Harris days
Obamacare will get retooled, not repealed. A national mask mandate will boost consumer spending, research shows (though don’t expect much from homeowners, they’re strapped). The $300 billion for R&D should go to D, not R. So forecasts an array of WashU experts.

Greenland Melting Likely Increased by Bacteria in Sediment
Bacteria are likely triggering greater melting on the Greenland ice sheet, possibly increasing the island’s contribution to sea-level rise, according to Rutgers scientists. That’s because the microbes cause sunlight-absorbing sediment to clump together and accumulate in the meltwater streams, according to a Rutgers-led study – the first of its kind – in the journal Geophysical Research Letters. The findings can be incorporated in climate models, leading to more accurate predictions of melting, scientists say.
Climate Change is Hurting Children’s Diets, Global Study Finds
A first-of-its-kind, international study of 107,000 children finds that higher temperatures are an equal or even greater contributor to child malnutrition than the traditional culprits of poverty, inadequate sanitation, and poor education.
The 19-nation study is the largest investigation to date of the relationship between our changing climate and children’s diet diversity.
Of the six regions examined–in Asia, Africa, and Central and South America–five had significant reductions in diet diversity associated with higher temperatures.

California Cities Top List of New Report Ranking U.S. Climate Action Plans
A new report evaluating the efficacy of climate action plans and commitments of the 100 largest U.S. cities finds the leadership of these municipalities stands as an important counter to the federal government’s rollback of climate policies and departure from the Paris Agreement. Yet, despite genuine achievements by some, roughly two-thirds of cities are currently lagging in their targeted emissions levels, and, on average, all cities in the report need to cut their annual emissions by 64% by 2050 in order to reach their respective goals.

UCI, others see agriculture as major source of increase in atmospheric nitrous oxide
Irvine, Calif., Oct. 8, 2020 – An international team of researchers – including Earth system scientists at the University of California, Irvine – recently completed the most thorough review yet of nitrous oxide from emission to destruction in the planet’s atmosphere. In addition to confirming that the 20 percent increase in the amount of the greenhouse gas since the start of the Industrial Revolution can be totally attributed to humans, the team expressed doubt about the ability to reduce emissions or mitigate their future impacts.
Global food production poses an increasing climate threat
A new study shows that rising nitrous oxide emissions are putting reaching climate goals and the objectives of the Paris Agreement in jeopardy.

Viruses could be harder to kill after adapting to warm environments
Enteroviruses that make their way into surface waters can be inactivated by heat, sunshine and other microbes, reducing their ability to spread disease. But researchers report that global warming could cause viruses to evolve, rendering them less susceptible to these and other disinfectants, such as chlorine.

What Happens in Vegas, May Come From the Arctic?
Climate records from a cave in the southern Great Basin show that Nevada was even hotter and drier in the past than it is today, and that one 4,000-year period in particular may represent a true, “worst-case” scenario for the Southwest and the Colorado River Basin — and the millions of people who rely on its water supply.
New international analysis narrows the range in sensitivity of climate to CO2
The most advanced and comprehensive analysis of climate sensitivity undertaken has revealed with more confidence than ever how sensitive the Earth’s climate is to carbon dioxide.
This new research finds that the true climate sensitivity is unlikely to be in the lowest part of the 2.7-8.1˚F range. The analysis indicates that if atmospheric carbon dioxide levels double from their pre-industrial levels and are maintained, the world would be likely to experience eventual warming from 4.1-8.1˚F. There would be less than 5 percent chance of staying below 3.6˚F and a 6-18 percent chance of exceeding 8.1˚F.
Free trade can prevent hunger caused by future shifts in climate patterns
International trade can compensate for regional reductions in agricultural production and reduce hunger when protectionist measures and other barriers to trade are eliminated.
Geoengineering is Just a Partial Solution to Fight Climate Change
Could we create massive sulfuric acid clouds that limit global warming and help meet the 2015 Paris international climate goals, while reducing unintended impacts? Yes, in theory, according to a Rutgers co-authored study in the journal Earth System Dynamics. Spraying sulfur dioxide into the upper atmosphere at different locations, to form sulfuric acid clouds that block some solar radiation, could be adjusted every year to keep global warming at levels set in the Paris goals. Such technology is known as geoengineering or climate intervention.
Geoengineering’s Benefits Limited for Apple Crops in India
Geoengineering – spraying sulfur dioxide into the atmosphere to combat global warming – would only temporarily and partially benefit apple production in northern India, according to a Rutgers co-authored study. But abruptly ending geoengineering might lead to total crop failure faster than if geoengineering were not done, according to the study – believed to be the first of its kind – in the journal Climatic Change.
