Is it feasible to remove carbon dioxide from the atmosphere?
Last week, the media reported that atmospheric carbon dioxide is at its highest levels in more than 4 million years. Carbon dioxide in the atmosphere is one of the primary drivers of global warming. The dip in greenhouse gases associated with reduced.....»»
The Italian central Apennines are a source of CO₂, study finds
Tectonically active mountains play an important role in the natural CO2 regulation of the atmosphere. Competing processes take place here: At Earth's surface, erosion drives weathering processes that absorb or release CO2, depending on the type of ro.....»»
Scientists develop novel aggregation-induced emission carbon dots for bioimaging
Carbon dots (CDs) are an intriguing class of nanomaterials that have attracted a great deal of attention in recent years. These carbon-based materials possess excellent fluorescence properties, making them highly appealing for a wide range of applica.....»»
Researchers reveal sources of black carbon in southeastern Qinghai-Tibet plateau
Black carbon (BC) is the result of incomplete combustion of fossil fuels and biomass, with strong light absorption. It is second only to carbon dioxide as a climate-forcing factor for atmospheric warming. Deposition of BC on snow and ice surfaces red.....»»
Using deep learning to image the Earth"s planetary boundary layer
Although the troposphere is often thought of as the closest layer of the atmosphere to the Earth's surface, the planetary boundary layer (PBL)—the lowest layer of the troposphere—is actually the part that most significantly influences weather nea.....»»
Effects of organic matter input and temperature change on soil aggregate-associated respiration and microbial carbon use
The Qinghai-Tibet Plateau is one of the most dramatically affected regions by global warming. For a long time, the region has been exposed by low temperature and soil moisture, which led to the severe inhibition of the soil biological activities and.....»»
Apple touts halving emissions and increased recycling rates in 2024 environmental progress report
Apple has an ambitious goal to create a fully carbon neutral value chain for its products by 2030, and every year it charts its progress in its annual Environmental Progress Report. The 2024 report published today highlights a milestone achievement f.....»»
The Rise of the Carbon Farmer
Farmers around the world are reigniting the less intensive agricultural practices of yesteryear—to improve soil health, raise yields, and trap carbon in the atmosphere back down in the soil......»»
Soil bacteria link their life strategies to soil conditions: Study
Soil bacteria help regulate the cycling of carbon and nutrients on Earth. Over time, these bacteria have evolved strategies that determine where they live, what they do, and how they deal with a changing environment. However, microbiologists do not f.....»»
Unique field study shows how climate change affects fire-impacted forests
During the unusually dry year of 2018, Sweden was hit by numerous forest fires. A research team led from Lund University in Sweden has investigated how climate change affects recently burned boreal forests and their ability to absorb carbon dioxide......»»
Understanding climate warming impacts on carbon release from the tundra
The warming climate shifts the dynamics of tundra environments and makes them release trapped carbon, according to a new study published in Nature. These changes could transform tundras from carbon sinks into carbon sources, exacerbating the effects.....»»
Light pollution affects coastal ecosystems, too—this underwater "canary" is warning of the impacts
In the early 20th century, canaries were used as early warning systems in coal mines to alert miners to rising levels of carbon monoxide......»»
NASA observations find what helps heat roots of "moss" on sun
Did you know the sun has moss? Due to its resemblance to the earthly plants, scientists have named a small-scale, bright, patchy structure made of plasma in the solar atmosphere "moss." This moss, which was first identified in 1999 by NASA's TRACE mi.....»»
Plant sensors could act as an early warning system for farmers
Using a pair of sensors made from carbon nanotubes, researchers from MIT and the Singapore-MIT Alliance for Research and Technology (SMART) have discovered signals that reveal when plans are experiencing stresses such as heat, light, or attack from i.....»»
Apple 2030 environmental goals: 95% of suppliers now using clean energy
We’ve today received an update on Apple’s 2030 environmental goals, one of which is for the company’s entire supply-chain to be carbon neutral by that date. The company says more than 320 suppliers – representing 95% of the company’s “.....»»
CO₂ worsens wildfires by helping plants grow, model experiments show
By fueling the growth of plants that become kindling, carbon dioxide is driving an increase in the severity and frequency of wildfires, according to a UC Riverside study......»»
Researchers reveal oceanic black carbon sink effect driven by seawater microdroplets
Pyrogenic carbon is widely produced during the incomplete combustion of biomass and fossil fuels on land. About one-third of pyrogenic carbon is exported to the ocean by rivers, and thereinto, the refractory fraction becomes the source of oceanic bla.....»»
Novel method developed for phosphorescent multi-color carbon dots
A research team has devised a novel method to prepare carbonized polymer nanodots capable of emitting multi-color ultra-long room-temperature phosphorescence (RTP) from blue to green......»»
From tape measures to space lasers: Quantifying biomass of the world"s tallest forests
In this era of accelerating climate crisis, accounting for all aspects of Earth's carbon cycle is a crucial task. The magnitude of atmospheric carbon burden means trees and forests are limited but important instruments among a suite of mitigation opt.....»»

How to keep Earth from being cooked by the ever-hotter Sun
Here are two options for future humans to keep us in the habitable zone. I’d wager a guess that we are, as a species, rather fond of our home planet (our wanton carbon emissions notwithstanding). But the ugly truth is that the Eart.....»»
