The research found “an almost complete loss of stability over the last century” of the currents that researchers call the Atlantic meridional overturning circulation (AMOC). The currents are already at their slowest point in at least 1,600 years, but the new analysis shows they may be nearing a shutdown.
As the world staggers through another summer of extreme weather, experts are noticing something different: 2021's onslaught is hitting harder and in places that have been spared global warming's wrath in the past.
Wealthy countries such as the United States, Canada, Germany and Belgium are joining poorer and more vulnerable nations on a growing list of extreme weather events that scientists say have some connection to human-caused climate change.
There is a realisation about the importance of Pancha Bhutas in the Indian ancient Knowledge systems and profess the need to maintain a balance. The journey of mankind to achieve progress and enhance the quality of life has resulted in imbalance, overexploitation of resources, and the planet’s survival is being challenged. It is crucial to be conscious that everything we do depend on Nature and impact it. Conservation of Nature is of utmost priority for all human beings and their life on this planet. World Nature Conservation Day is observed on July 28 to raise awareness about the importance of preserving natural resources and protecting them. The origin of commemorating and the history of World Conservation Day is unknown. It is good to see people worldwide come together and organise events to preserve precious natural resources.
By putting the recycling costs on the producer rather than the consumer, Maine becomes the first U.S. state to hold companies responsible for the waste they create.
In putting what is essentially an import duty on packaging, Maine is telling companies there is a limit to the amount of reliance they can have on Mainers and municipalities to recycle their material.
Last week, Ken Bossong of the SUN DAY campaign said that data released over the past decade by the U.S. Energy Information Administration (EIA) and the Federal Energy Regulatory Commission (FERC) as well as near-term forecasts by both agencies suggest continued strong growth by renewable energy sources. However, unless accelerated, that growth will fall short of President Biden’s clean power goals for 2030.
EIA’s data from the past ten years indicate renewables could be one-third of U.S. electrical generation in 2030.
Scientists worry that growing numbers of rocket flights and the rise of space tourism could harm Earth's atmosphere and contribute to climate change.
When billionaires Richard Branson and Jeff Bezos soared into space this month aboard their companies' suborbital tourism vehicles, much of the world clapped in awe.
But for some scientists, these milestones represented something other than just a technical accomplishment. Achieved after years of delays and despite significant setbacks, the flights marked the potential beginning of a long-awaited era that might see rockets fly through the so-far rather pristine upper layers of the atmosphere far more often than they do today. In the case of SpaceShipTwo, the vehicle operated by Branson's Virgin Galactic, these flights are powered by a hybrid engine that burns rubber and leaves behind a cloud of soot.
The Little Rocky Mountains in Montana form an island range in a sea of prairie. As a result of their isolation, they are home to plant and wildlife species that are not found anywhere nearby, leaving them especially vulnerable to climate change impacts. In the shadow of the Little Rockies, the Aaniiih and Nakoda peoples of the Fort Belknap Indian Community are taking a bold stand to protect this mountain ecosystem to help preserve their traditional ways of life. The Center is supporting this effort by assisting them in restoring forest health and planning for a rapidly changing climate.
Researchers in the BOTTLE Consortium, including from the U.S. Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL) and the University of Portsmouth, have identified using enzymes as a more sustainable approach for recycling polyethylene terephthalate (PET), a common plastic in single-use beverage bottles, clothing, and food packaging that are becoming increasingly relevant in addressing the environmental challenge of plastic pollution. An analysis shows enzyme-recycled PET has potential improvement over conventional, fossil-based methods of PET production across a broad spectrum of energy, carbon, and socioeconomic impacts.
This report, prepared by IEA Bioenergy Task 39, provides an extensive analysis of the current and potential technologies for production of biomass based sustainable aviation fuels (Biojet/SAF).
Sustainable Aviation Fuels will have to play a major role if the aviation sector is to significantly reduce its carbon footprint. However, to date, commercialization has been slow and current policies have proved inadequate to accelerate commercialization and widespread deployment of the various technologies described in the report.
Long before the current political divide over climate change, and even before the U.S. Civil War (1861-1865), an American scientist named Eunice Foote documented the underlying cause of today’s climate change crisis.
The year was 1856. Foote’s brief scientific paper was the first to describe the extraordinary power of carbon dioxide gas to absorb heat – the driving force of global warming.
