Aviation’s present-day contribution to human-induced global warming is 4% and will increase over the next 30 years should pre-Covid growth resume
Aviation is responsible for more global warming than implied by its carbon footprint alone. According to new research published today, aviation could consume up one-sixth of the remaining temperature budget required to limit warming to 1.5˚C by 2050.

UNH Receives $1.8 Million Grant to Study Road Resilience to Sea Level Rise
After a summer of high heat, steady sea level rise and devastating hurricanes, coastal roads have continued to take a severe beating resulting in endless wear and tear. Because these roadways have become increasingly vulnerable, the National Oceanic and Atmospheric Administration (NOAA) has awarded a $1.8 million grant to researchers at the University of New Hampshire to study how and why coastal hazards like excessive flooding are causing roads to crack and crumble and find ways to protect them.

World’s Lakes Losing Oxygen Rapidly as Planet Warms
Oxygen levels in the world’s temperate freshwater lakes are declining rapidly — faster than in the oceans — a trend driven largely by climate change that threatens freshwater biodiversity and drinking water quality.
Warm ice may fracture differently than cold ice
Researchers at Aalto University in Finland have found strong evidence that warm ice – that is, ice very close in temperature to zero degrees Celsius – may fracture differently than the kinds of ice typically studied in laboratories or nature. A new study published in The Cryosphere takes a closer look at the phenomenon, studied at the world’s largest indoor ice tank on Aalto’s campus.
Satellites may have underestimated warming in the lower atmosphere
New research by Lawrence Livermore National Laboratory (LLNL) climate scientists and collaborators shows that satellite measurements of the temperature of the troposphere (the lowest region of the atmosphere) may have underestimated global warming over the last 40 years.
Observations show marine clouds amplify global warming
A new analysis of satellite cloud observations finds that global warming causes low-level clouds over the oceans to decrease, leading to further warming. The work, led by researchers at Lawrence Livermore National Laboratory (LLNL), in collaboration with colleagues from Scripps Institution of Oceanography and the NASA Langley Research Center.
Study Finds 6⁰C Cooling on Land during the Last Ice Age, With Implications about Future Global Warming
Prior studies have underestimated the cooling in the last glacial period, which has low-balled estimates of the Earth’s climate sensitivity to greenhouse gases. The rather high climate sensitivity is not good news regarding future global warming, which may be stronger than expected using previous best estimates.

Catastrophic Sea-Level Rise from Antarctic Melting is Possible with Severe Global Warming
The Antarctic ice sheet is much less likely to become unstable and cause dramatic sea-level rise in upcoming centuries if the world follows policies that keep global warming below a key 2015 Paris climate agreement target, according to a Rutgers coauthored study. But if global warming exceeds the target – 2 degrees Celsius (3.6 degrees Fahrenheit) – the risk of ice shelves around the ice sheet’s perimeter melting would increase significantly, and their collapse would trigger rapid Antarctic melting. That would result in at least 0.07 inches of global average sea-level rise a year in 2060 and beyond, according to the study in the journal Nature.

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.

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.

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.
