Nature’s Fork in the Road: Soil’s Carbon Capture Dilemma

Researchers identified key factors that determine if soil traps carbon or releases it as CO2, highlighting the role of molecular interactions and soil chemistry, potentially aiding climate change mitigation efforts.

Do Electric Vehicles Contribute To Air Pollution? Here’s What Experts Have To Say

Last Updated: February 28, 2024, 16:55 ISTDo Electric Vehicles Contribute To Air Pollution? Here’s What Experts Have To Say. (Representative Image) (Photo: Canary Media)While electric cars have zero engine pollution, friction is still needed for the tyres and brakes to function.Several countries have prioritised the transition to electric vehicles (EVs) in their efforts to meet their climate targets.Electric vehicles emit no tailpipe emissions when compared to traditional vehicles that run on fossil fuel. This has the…

The 50,000% Carbon Time Bomb Ticking Towards 2100

Research predicts a near 50,000% increase in carbon emissions from mangrove degradation by 2100, emphasizing the urgent need for conservation in face of human development and rising population densities. Credit: IOP PublishingAlarming projections show a significant rise in carbon emissions from mangrove forests by 2100, highlighting the critical need for protection and understanding of human impacts on these vital ecosystems.The annual rate of carbon emissions due to the degradation of carbon stocks in mangrove forests is…

What Would Happen if Every American Got a Heat Pump

“The answer ended up being, yes, in all US states, on average heat pumps will reduce greenhouse gas emissions,” says Eric Wilson, a senior research engineer at the National Renewable Energy Laboratory and the lead author of the new paper. “Even if it’s a relatively low-efficiency heat pump that relies on electric resistance heating during the coldest times, and even if it’s the most pessimistic grid scenario that has prices for wind and solar being higher than their current trajectory has been.”Because a heat pump can be…

Unlocking the Mystery of Arctic Wetlands’ Methane Emissions Surge

A research team from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) analyzed wetland…

Ocean Temperatures Keep Shattering Records—and Stunning Scientists

So what’s going on here? For one, the oceans have been steadily warming over the decades, absorbing something like 90 percent of the extra heat that humans have added to the atmosphere. “The oceans are our saviors, in a way,” says biological oceanographer Francisco Chavez of the Monterey Bay Aquarium Research Institute in California. “Things might be a lot worse in terms of climate impacts, because a lot of that heat is not only kept at the surface, it’s taken to depths.”A major concern with such warm surface temperatures…

Unraveling Climate Impact on Wetlands

A Tulane University study published in Nature Communications reveals the potential long-term effects of climate change on coastal wetlands, using a real-world experiment along the Gulf Coast. By leveraging a network of nearly 400 monitoring sites and novel satellite data techniques, the study found that nearly 90% of sites were unable to keep pace with the rapid sea-level rise, simulating conditions expected around 2070. The research underscores the urgency of adhering to the Paris Agreement to mitigate future wetland…

Global Warming’s New Threat: Arctic Permafrost’s Carbon Bomb

Recent Dartmouth research underscores the significant influence of Arctic permafrost on the formation of northernmost rivers and highlights the risks of substantial carbon release due to climate change-induced thawing. By analyzing thousands of watersheds, the study reveals the unique characteristics of Arctic river valleys and stresses the importance of understanding these landscapes in the face of global warming. Credit: SciTechDaily.comAs the Arctic warms, the growth of rivers could release carbon emissions equivalent…

The Feds Just Bet Even Bigger on American-Made Heat Pumps

While everyone’s been focused on accelerating the adoption of electric vehicles to cut carbon emissions, a technological hero has been rapidly ascending under the radar: the heat pump. Instead of burning natural gas or coal to produce heat, this fully electric device extracts warmth from outdoor air—even when it’s freezing outside—and pumps it inside to warm a structure. After years of stealthy, steady growth, heat pumps are now outselling gas furnaces in the United States, whereas EVs accounted for just 8 percent of all…

370 Million Tons – Landmark Study Uncovers New Source of Carbon Emissions

Bottom trawling significantly contributes to atmospheric carbon emissions by disturbing ocean sediments, a study finds. This method not only harms marine ecosystems but also releases vast amounts of carbon dioxide, doubling the emissions from the global fishing fleet’s fuel use. Immediate policy action is urged to address this overlooked source of carbon pollution and mitigate its impact on climate change and ocean health.A landmark study has uncovered that bottom trawling contributes to the release of as much as 370…
