Over the course of nearly two decades, its powerful radar provided never-before-seen details of clouds and helped advance global weather and climate predictions.

CloudSat, a NASA mission that peered into hurricanes, tallied global snowfall rates, and achieved other weather and climate firsts, has ended its operations. Originally proposed as a 22-month mission, the spacecraft was recently decommissioned after almost 18 years observing the vertical structure and ice/water content of clouds.

Engineers at Georgia Tech have designed a process that converts carbon dioxide removed from the air into useful raw material that could be used for new plastics, chemicals, or fuels.

Their approach dramatically reduces the cost and energy required for these direct air capture (DAC) systems, helping improve the economics of a process the researchers said will be critical to addressing climate change.

The key is a new kind of catalyst and electrochemical reactor design that can be easily integrated into existing DAC systems to produce useful carbon monoxide (CO) gas. It’s one of the most efficient such design ever described in scientific literature, according to lead researcher Marta Hatzell and her team. They have published the details in Energy & Environmental Science.

When facing a predator, single cells sometimes unite to defend themselves, paving the way for more complex multicellular life forms to evolve.

A recent study published in the journal Nature by an international team of 279 scientists, including three biologists from the University of Michigan, provides the latest insights into the flowering plant tree of life.

Using 1.8 billion letters of genetic code from more than 9,500 species covering almost 8,000 known flowering plant genera (ca. 60%), this achievement sheds new light on the evolutionary history of flowering plants and their rise to ecological dominance on Earth.

Led by scientists at the Royal Botanic Gardens, Kew, the research team believes the data will aid future attempts to identify new species, refine plant classification, uncover new medicinal compounds, and conserve plants in the face of climate change and biodiversity loss.

Atmospheric water generators can save millions of lives due to new drought conditions even bringing water from air in the desert climates.

• Water scarcity continues to be a pervasive global challenge, cutting across developed and emerging markets, climates and socio-political dynamics.
• Atmospheric water generation (AWG) technology is a promising emergency solution that can immediately generate drinkable water using moisture in the air.
• Distribution of atmospheric water generation technology to communities in need can serve as an effective stopgap measure for municipalities facing immediate clean water shortages.

The statistics underpinning water scarcity are dire and noteworthy – approximately 770 million people lack access to clean water. That is one in ten people on the planet. The average woman in rural Africa walks 6 kilometres (about 3.7 miles) daily to haul 40 pounds of water.

Land subsidence is overlooked as a hazard in cities, according to scientists from the University of East Anglia (UEA) and Virginia Tech. Writing in the journal Science, Prof Robert Nicholls of the Tyndall Center for Climate Change Research at UEA and Prof Manoochehr Shirzaei of Virginia Tech and United Nations University for Water, Environment and Health, Ontario, highlight the importance of a new research paper analyzing satellite data that accurately and consistently maps land movement across China.

With climate change warming the oceans, this results in drastic consequences for marine life in deep water environments, but can steps be taken to help mitigate these effects? This is what a recent study published in Nature Communications hopes to address as a team of researchers from the United Kingdom investigated how “mixing down” oxygen levels in the ocean could help contribute to a more suitable environment for deep sea life. This study holds the potential to help scientists, conservationists, legislators, and the public better understand the steps that can be taken to mitigate the long-term effects of climate change.

Decreasing oxygen levels in the ocean is a natural phenomenon, but climate change has been predicted to accelerate this process, which could lead to massive decreases in oxygen levels in deep water environments and pose catastrophic consequences for marine life. For the study, the researchers used new methods that combine ocean water data from the Celtic Sea and computer models to ascertain how deep water oxygen levels could be replenished during the warmer summer months. In the end, they determined that summertime storms can result in the “mixing down” of oxygen and decrease this oxygen loss by almost half, which also shows promise for putting floating wind farms in the northern North Sea and Celtic Sea to assist in this process.

“There is growing concern for the health of our coastal oceans as the climate warms because warmer water holds less oxygen,” said Dr. Tom Rippeth, who is a Professor of Physical Oceanography at Bangor University and lead author of the study. “Living creatures in the ocean are reliant on oxygen to survive in the same way as animals on land are. Oxygen is also used up as rotting matter decomposes in the depths of the ocean. This creates a summer oxygen deficit in the deep seas around the UK. Unfortunately, as our climate warms, this deficit is forecast to grow.”

One hundred twenty satellites, with their own distinct purpose, hover our Earth. How the structure of continents, the sun, human interaction and many other factors contribute to Earth’s climate and survival/evolution of life.

“We need to accelerate and intensify efforts to recover Antarctic meteorites,” said Dr. Harry Zekollari. “The loss of Antarctic meteorites is much like the loss of data that scientists glean from ice cores collected from vanishing glaciers – once they disappear, so do some of the secrets of the universe.”

How can climate change effect the search for meteorites in Antarctica? This is what a recent study published in Nature Climate Change hopes to address as an international team of researchers investigated how melting snow and ice could prevent successful identification of meteorites, of which approximately 60 percent of all meteorites retrieved on Earth have been found in Antarctica. This study holds the potential to help scientists, climate change activists, and legislators better understand the impacts of climate change on science, as meteorites are crucial for gaining greater insight into the formation and evolution of the solar system and beyond.

With a combination of climate models, satellite observations, and artificial intelligence, the researchers estimate that at current rates, they will lose the ability to identify approximately 5,000 meteorites annually, with approximately 24 percent being lost by 2050 and potentially 76 percent by 2100.
