When forecasting how storms may change in the future, it helps to know something about their past. Judging from historical records dating back to the 1850s, hurricanes in the North Atlantic have become more frequent over the last 150 years.

Ocean predators cannot survive on average concentrations of food found in the water. Instead, they survive by exploiting small patches of food-rich areas peppered throughout the world's waterways. Using active acoustics, researchers found the ocean is widely populated with narrow hotspots of activity. Traditionally, these hotspots are missed with conventional sampling tools, but locating them can provide dynamic layered maps of ocean life. The findings signify ocean food and biota as patchy, varying with depth and location, suggesting animals must find and exploit small-scale aggregations of resources.
Using artificial intelligence techniques, an international team that included Rutgers-New Brunswick researchers have traced the evolution of coccolithophores, an ocean-dwelling phytoplankton group, over 2.8 million years. Their findings, published this week in the journal Nature, reveal new evidence that evolutionary cycles in a marine phytoplankton group are related to changes in tropical seasonality, shedding light on the link between biological evolution and climate change.
All land plants originated from a single evolutionary event when freshwater algae got a foothold on land, giving rise to an astonishing biodiversity of plants on earth.

Snow monkeys living in one of the world’s coldest regions survive by ‘going fishing’ – scooping live animals, including brown trout, out of Japanese rivers and eating them to stay alive, a new study reveals.
Unless climate change is slowed significantly, more than three feet of sea level rise (SLR) is expected in California by the end of the century, potentially flooding communities that are currently home to more than 145,000 residents. In addition to the threat to residential neighborhoods, new research suggests sea level rise will expose over 400 industrial facilities and contaminated sites in California, including power plants, refineries, and hazardous waste sites, to increased risk of flooding. Increased flooding can come with risks of contamination releases into nearby communities.
Waterfalls have a specific threshold of water flow that must be maintained to preserve their characteristic sound and appearance, according to research that used audio recordings and images to monitor waterfalls in Europe.
The world’s eight most extreme wildfire weather years have occurred in the last decade, according to a new study that suggests extreme fire weather is being driven by a decrease in atmospheric humidity coupled with rising temperatures.
Beginning in January 2022, the Journal of Nutrition Education and Behavior will become an online journal.
New research finds that Arctic krill have a biological response to changes in light. When it is lightest in the Arctic polar night, usually around the middle of the day known as midday twilight, the krill know to swim down to the bottom in order to hide from predators. When it is darkest in the Arctic polar night, that’s when they swim to the surface in search of bioluminescent food.
Nebraska scientist says time is running out for West Antarctic ice sheet
A new study co-led by a Cornell researcher has identified serpentinite – a green rock that looks a bit like snakeskin and holds fluids in its mineral structures – as a key driver of the oxygen recycling process, which helped create and maintain the sustaining atmosphere for life on Earth.
A new international study coordinated by IIASA shows how near-term mitigation can help to prevent an overshoot in global temperatures, thereby reducing climate risks and bringing long-term economic gains.
A new IIASA-led study explored the use of a citizen science tool known as Picture Pile to see how it could contribute to monitoring progress towards the UN Sustainable Development Goals (SDGs).
The Arctic Ocean has been getting warmer since the beginning of the 20th century – decades earlier than records suggest – due to warmer water flowing into the delicate polar ecosystem from the Atlantic Ocean.
Steven Koonin, former Undersecretary for Science in the Obama Administration says that the media is exaggerating the climate crisis. In a recent video for Prager U, Koonin offered several statements that address flooding, hurricanes and the melting of the Greenland Ice Sheet. We address the claim that "Greenland's ice sheet isn't shrinking any more rapidly today than it was 80 years ago." Our analysis: this claim is mostly false.
Million years of evolution have produced a dazzling variety of species, each uniquely adapted to its environment.
New research has shed light on a sudden cooling event 34 million years ago, which contributed to formation of the Antarctic ice sheets.
A little-known species of tropical bee has evolved an extra tooth for biting flesh and a gut that more closely resembles that of vultures rather than other bees.
In California’s Sierra Nevada, western pine beetle infestations amped up by global warming were found to kill 30% more ponderosa pine trees than the beetles do under drought alone.
Pavlos Kollias, PhD, of Stony Brook University, is part of a new NASA Earth Science mission that aims to yield new information about tropical storm clouds –data that will help scientists better understand and predict the behavior of dangerous tropical storms and address a significant issue of climate change.

Researchers report in ACS’ Environmental Science & Technology Letters that satellite data from before & during the spring 2020 lockdown in Los Angeles shows that vehicles are the main source of urban airborne ammonia, which forms small particles that contribute to air pollution & harm human health.
Scientists now understand how certain animals can feed on picturesque, orange monarch butterflies, which are filled from head to abdomen with milkweed plant toxins.
A new, widespread study of the global state of marine coral reef wilderness by WCS, NGS, and university collaborators found that remote ocean wilderness areas are sustaining fish populations much better than some of the world’s best marine reserves.
A new study that looks at an eye disease in house finches shows how behavior and disease pathology interact to contribute to the spread of a pathogen. The study appears in the academic journal Biology Letters.

After the natural warming that followed the last Ice Age, there were repeated periods when masses of icebergs broke off from Antarctica into the Southern Ocean.
The ice sheets of Greenland are melting at an alarming rate. This causes large amounts of freshwater to flow into the North Atlantic, thereby slowing the Gulf Stream.
A new study describes a proof of principle for engineering a bacterium, Gluconobacter oxydans, that takes a big first step towards meeting skyrocketing rare earth element demand in a way that matches the cost and efficiency of traditional thermochemical extraction and refinement methods and is clean enough to meet U.S. environmental standards.

The tiny cosmos of organisms living on a streamer of algae in a river could help scientists learn what turns an environment from healthy to toxic and back again. A multidisciplinary team led by NAU has won $3 million from the NSF to translate the codex contained in the microbiome of common algae into computer algorithms that can predict a wide range of microbial interactions.
The World Climate Conference in Glasgow has just ended. Empa researchers show how the energy transition could lead to the lowest possible cumulative emissions: Instead of slowly cutting back emissions, we should quickly push ahead with the conversion to solar energy and use fossil power plants at full capacity for one last time to do so.
Naturalist John Muir called the Sierra Nevada “the Range of Light.” But a more ominous nickname, “the Range of Fire,” may lie ahead, according to new research from the University of California, Irvine. By 2040, as humans continue to change the climate, fire-conducive heat waves will become so common that the number of blazes throughout the Sierra stands to increase about 50 percent, researchers found.
The humdrum task of garbage-sorting can elicit confusion or even suspicion. Compost? Recycle? Are those corn-based disposable forks truly compostable or are they just feel-good trash? Many recyclable plastics never even make it into the right bin, and while products with terms like “eco” and “plant-derived” in their brand names can let us feel like we are making Earth-friendly choices, scientists say their benefits may be oversold.
Scientists warn, without good biosecurity measures ‘alien organisms’ on Earth may become a reality stranger than fiction. Scientists warn, without good biosecurity measures ‘alien organisms’ on Earth may become a reality stranger than fiction.
