Aerobic methane-oxidizing bacteria (MOB) remain active even in oxygen-free water. MOB contain specific genes that are used for methane-based fermentation and allow the bacteria to act as a sink for methane carbon. The importance of MOB for methane degradation is expected to grow as climate change affects conditions in anoxic...

Methane-Oxidizing Bacteria Combat Climate Change

A new study examining ancient temperatures and rainfall patterns in the tropical Andes of South America has revealed how climate history in this region over the past 16,000 years was influenced by carbon dioxide levels and ocean currents linked to global climate events. The study, led by researchers from Brown...

The world’s oceans are home to microscopic organisms invisible to the human eye. The tiny creatures, known as “prokaryotes”, comprise 30% of life in the world’s oceans.

These organisms play an important role in keeping the oceans in balance. But new research by myself and colleagues shows this balance is at risk.

We found prokaryotes are remarkably resilient to climate change – and as a result, could increasingly dominate marine environments. 

This could reduce the availability of fish humans rely on for food, and hamper the ocean’s ability to absorb carbon emissions.



A fine balance

Prokaryotes include both bacteria and “archaea”, another type of...

Earth’s oldest, tiniest creatures are poised to be climate change winners – and the repercussions could be huge

In 2017, the Minamata Convention on Mercury went into effect, designed to help curb mercury emissions and limit exposure across the globe. However, a new study of mercury levels in soil suggests that the treaty's provisions might not be enough. A study published in Environmental Science & Technology estimates that soil stores substantially more mercury than previously thought, and it predicts that increases in plant growth due to climate change may add even more.

Editor's note: This article was originally published on April 25, 2022. It has since been updated. Even as activists continue to face opposition—and even disdain—from climate deniers for attempting to raise awareness about the danger our planet is in, mounting scientific data shows that the world's ice is melting at a rapid pace. According to a study published earlier in 2021, global ice loss has increased rapidly over the past two decades, soaring from about 760 billion tons per year in the 1990s to more than 1.2 trillion tons per year in the 2010s. Meanwhile, a second, NASA-backed study on the Greenland ice sheet found that at least 74 major glaciers that terminate in deep, warming ocean waters are being severely undercut and weakened.

What would the Earth look like if all the ice melted? The answer is terrifying.

On Sunday, Earth experienced its hottest day ever recorded in human history, according to the European climate service Copernicus. That record was then broken the very next day, underlining the troubling trajectory global temperatures have taken in the last several years. The European Union's Copernicus satellite produced preliminary data showing...

Humanity will "scorch and fry”: The hottest day in human history just happened twice in a row

Sunday was Earth’s hottest day on record, according to a European climate tracking agency.Based on preliminary data, July 21 clocked a daily global average temperature of 17.09℃ (63℉) slightly exceeding the previous record of 17.08℃ in the same month of 2023.The EU’s Copernicus Climate Change Service said it will not be the last record-breaker, as planet-warming fossil fuel pollution drives temperatures to shocking new highs.Global averages typically peak during the Northern Hemisphere summer, between late June and early August.The record fell as many countries endure prolonged and brutal heatwaves. Swathes of southern Europe have been grappling with soaring temperatures and...

Seismologists measure tremors from distances up to 5000 km away. On September 16, 2023, a massive wave struck a fjord on Greenland’s east coast, leaving evidence of flooding up to 200 meters (650 feet) high in some areas. Researchers, led by Angela Carrillo Ponce from the German Research Centre for Geosciences (GFZ), have analyzed seismic data from earthquake monitoring stations worldwide and uncovered another remarkable event. The megatsunami triggered a standing wave that oscillated back and forth in the narrow, uninhabited Dickson Fjord for over a week. The international team has published their findings in the journal The Seismic Records.

Primary school geography paints such a neat picture of the world.It tells us, for example, that there are seven continents on Earth, but the truth is far more complex.Researchers are constantly encountering lost landmasses that constitute important pieces in the puzzle of our planet’s geological past.Now, a whole new continent has been found lurking beneath the icy waters of the northern Atlantic Ocean.The discovery was made around the Davis Strait, a large stretch of water located between Canada’s Baffin Island and Greenland.The strait was formed millions of years ago when the tectonic plates between the two islands shifted, reconfiguring the...

Ozone can be an agent of good or harm, depending on where you find it in the atmosphere. Way up in the stratosphere, the colorless gas shields the Earth from the sun's harsh ultraviolet rays. But closer to the ground, ozone is a harmful air pollutant that can trigger chronic health problems including chest pain, difficulty breathing, and impaired lung function.

The ocean has a major influence on weather and climate. Scientists estimate it has absorbed more than 90% of the heat and 25% of the excess carbon released into the atmosphere by human activities. As the climate crisis grows more dire, it is increasingly urgent that we understand the exchange...

A bill quietly introduced this spring in the Colorado legislature to decriminalize the possession of drug paraphernalia obtained by harm reductionists has become law. As low-key as the legislation was introduced, the bill was signed into law without fanfare June 6. It garnered little to no media attention.

Imagine this dire scenario: the Atlantic Ocean's sea currents which bring warm water to Europe collapses, making large swaths of the continent as cold as the Arctic Circle. In a grim turn, that's just the scenario that a team of European scientists are warning about in a new study in the journal Nature Communications: that this catastrophic collapse — along with the ruination of the Amazon rainforest and the melting of polar ice — is on track to actually happen if we continue along our current path.

Major Earth Systems on Track for Collapse, Scientists Find

As global temperatures keep rising because of human activities like burning fossil fuels and cutting down forests, Earth is getting closer to critical points that could permanently disrupt its complex systems. Our planet is in a dangerously precarious state. Pretending otherwise, or simply continuing to ignore the issue, definitely won’t...

Consumer insecticide sprays provide “little to no value” against German cockroach infestations, researchers say. A study has found that most consumer insecticide sprays are ineffective against German cockroaches, with over 80% of these pests surviving exposure to common pyrethroid-based products. Researchers emphasize the need for better testing standards and more effective pest control strategies, including integrated pest management.

As extreme weather and high temperatures spurred on by humankind's industrial presence continue to impact our planet, we must rely on research and data collection to stay informed. So, it's especially concerning that researchers have discovered a major oversight in Antarctic ice shelf climate models, as Phys.org reported. What's happening?

You’re reading this because something catastrophic terminated the more than 150-million-year reign of the dinosaurs. What opened the doors for mammals to dominate Earth was likely an extraterrestrial object; probably an asteroid. Where that asteroid came from has not been entirely clear. But new research might have gotten a giant step closer to solving this mystery. According to a study published Thursday in the journal Science, the rogue space rock probably came from far beyond Jupiter, and was likely laced with traces from the stars that existed before the Sun.
