Tropical forests are clearly critical to Earth’s climate system, but understanding exactly how much carbon they absorb from the atmosphere, store and release is tricky to calculate, not least because measuring and reporting methods vary. With these measurements paramount for nations assessing the action they are taking to combat the climate crisis, new research shows how differences in estimates of carbon flux associated with human activity can be reconciled.
A new study in Nature Climate Change takes one of the first deep dives into how climate change will affect the fastest jet streams—the powerful, narrow winds in the upper atmosphere that steer much of the Earth’s weather systems and are connected to outbreaks of severe weather.
The ocean’s capacity to store atmospheric carbon dioxide is some 20% greater than the estimates contained in the latest IPCC report. These are the findings of a study published in the journal Nature led by an international team including a biologist from the CNRS. The scientists looked at the role played by plankton in the natural transport of carbon from surface waters down to the seabed.
New research has shown that fire-ice—frozen methane which is trapped as a solid under our oceans—is vulnerable to melting due to climate change and could be released into the sea.
A new study from researchers at UC San Diego’s Scripps Institution of Oceanography and UC San Francisco estimates 152,753 excess infant deaths were attributable to living in flood-prone areas in Bangladesh over the past 30 years. Additionally, across the study period, children born during rainy months faced a higher risk of death than those born in dry months.
Tiny fossils in marine sediments verify that climate models provide accurate calculations of average ocean temperatures during the last glacial maximum around 20,000 years ago, but that the spatial distribution of simulated temperatures is too uniform and thus only partially valid for predicting future climate.
Pine Island Glacier in West Antarctica has gone through an irreversible retreat, passing a tipping point within the last 80 years, researchers have found.
An interdisciplinary research team from the University of Waterloo is using artificial intelligence (AI) to identify microplastics faster and more accurately than ever before.
Biomass burning from wildfires puts large amounts of aromatic hydrocarbons in the atmosphere every year, which are thought to convert into more light-absorbing and toxic nitroaromatics.
The world may cross the crucial 1.5C global warming threshold in seven years as fossil fuel CO2 emissions continue to rise, scientists warned Tuesday, urging countries at the COP28 talks to “act now” on coal, oil and gas pollution.
Global carbon emissions from fossil fuels have risen again in 2023—reaching record levels, according to new research from the Global Carbon Project science team.
You need only to remember last summer’s wildfires in the United States and Canada, which fouled the air from coast to coast, to know the effects these blazes can have on the environment and human health.
A consideration of how mountains influence El Niño and La Niña-induced precipitation change in western North America may be the ticket to more informed water conservation planning along the Colorado River, new research suggests.
Himalayan Glaciers fight back to preserve themselves, but for how long? An international team of researchers, co-led by Professor Francesca Pellicciotti of the Institute of Science and Technology Austria (ISTA), explains a stunning phenomenon: rising global temperatures have led Himalayan glaciers to increasingly cool the air in contact with the ice surface. The ensuing cold winds might help cool the glaciers and preserve the surrounding ecosystems. The results, found across the Himalayan range, were published in Nature Geoscience.
A recent study published in the Journal of Geophysical Research: Solid Earth sheds new light on the formation of the East Coast of the United States—a “passive margin,” in geologic terms—during the breakup of the supercontinent Pangea and the opening of the Atlantic Ocean around 230 million years ago.
Simultaneous episodes of extreme heat and drought—typical of a moderate warming scenario predicted for the end of the 21st century—could occur earlier and repeatedly in Europe, reports a study published in Communications Earth & Environment.
Writing in the journal Nature ahead of COP28, a team of Met Office scientists has emphasized that—surprisingly—there is currently no formally agreed way of defining the current level of global warming relevant to the Paris Agreement.
Commonly associated with longer days and slower paces, this summer’s record-smashing heat in Arizona demonstrated a concerning future for the planet’s warmest season. From power outages endangering entire neighborhoods and heat-related deaths rising among some of the state’s most vulnerable populations, the city of Phoenix found itself in national headlines. As national attention grew, one question became clear: How does anyone live there?
While the impacts of climate change vary across the globe, most scientists agree that, overall, a warming environment is increasing both the frequency and intensity of severe weather events such as tornados and intense thunderstorms.
A team of scientists found that carbon dioxide becomes a more potent greenhouse gas as more is released into the atmosphere.
Over the past decades, environmental scientists and engineers have been trying to devise effective solutions to reduce greenhouse gas emissions and mitigate the adverse effects of climate change. This has led to the creation of various energy models, frameworks that can be used to investigate emission mitigation scenarios in the hope of meeting the goals outlined by the Paris Agreement.
MIT geologists have found that a clay mineral on the seafloor, called smectite, has a surprisingly powerful ability to sequester carbon over millions of years.
Melting of glaciers, rising sea levels, extreme heat waves: the consequences of climate change are more visible than ever, and the scientific community has confirmed that humans are responsible. Yet studies show that a third of the population still doubts or disputes these facts.
Coral reefs, among the most diverse and valuable ecosystems on Earth, are under threat due to the changing climate. In a new study, an international research team found that if reefs were to disappear entirely, it may take millions of years—even after environmental conditions improve—for them to recover.
Man-made global warming exacerbated an incident of extreme flooding and heat in eastern China in 2020, according to a study released Wednesday, which highlighted the need to prepare for increasingly intense episodes of such weather in the country.
Nineteen million years ago, during a time known as the early Miocene, massive ice sheets in Antarctica rapidly and repeatedly grew and receded. The Miocene is widely considered a potential analog for Earth’s climate in the coming century, should humanity remain on its current carbon emissions trajectory.
The costs of environmental pollution caused by plastics in cigarette butts and packaging amount to an estimated US $26 billion every year or US $186 billion every 10 years—adjusted for inflation—in waste management and marine ecosystem damage worldwide, finds a data analysis published online in the journal Tobacco Control.
