Researchers at East China Normal University (ECNU), Shanghai, have unveiled a groundbreaking approach to waste management that offers a potential "closed loop" solution. This process utilizes seawater and sunlight to recycle plastics, providing a cost-effective and environmentally friendly solution to the global plastic waste crisis.
A recent whitepaper challenges the prevailing notion that the Science Based Targets Initiative (SBTi) is universally effective for measuring and curbing organizations' environmental impact. Authored by sustainability consultancy Eight Versa, the paper contends that SBTi's "absolute contraction" approach to achieving a 90% emission reduction within three decades is ill-suited for small and medium-sized enterprises (SMEs). Instead, the paper suggests embracing an "Intensity Metric" approach, particularly for SMEs, to address carbon and other climate-negative outputs.
Climate change is a complex issue with far-reaching consequences. One of the potential impacts of climate change is an increase in the frequency and severity of earthquakes and volcanic eruptions.
Archaeologists from the University of Exeter have harnessed laser scans from the Environment Agency's National LiDAR Programme to uncover a previously unknown Roman road network that spanned across Devon and Cornwall. This remarkable discovery challenges existing assumptions about the Roman road system and offers insights into the historical connections between significant settlements and military forts.
A groundbreaking study by researchers from the University of Bristol has uncovered that Heliconius butterflies possess spatial learning capabilities, marking the first experimental evidence of such skills in any butterfly or moth species. Published in Current Biology, the findings indicate that these butterflies can remember the locations of food sources across substantial distances, challenging previous assumptions about insect cognition.
A recent study led by researchers at Washington University in St. Louis highlights that the impact of wildfires on climate change may be more substantial than previously understood. The study, published in Nature Geoscience, delves into the role of "dark brown carbon," a previously unidentified class of particles emitted as part of wildfire smoke. The findings suggest that these particles contribute significantly to the warming effect, necessitating revisions in climate models and strategies to address a changing environment.
Amidst relentless heatwaves, scientists predict that July is on track to become the hottest month ever recorded, surpassing previous records set in 2019. With several days left in the month, experts are confident that this year's record will be shattered. The sweltering temperatures are attributed primarily to the relentless consumption of fossil fuels, according to climate researchers. UN Secretary-General Antonio Guterres warns that the world is entering an "era of global boiling," and US President Joe Biden labels climate change an "existential threat."
Shifting away from fossil fuels is leading to a transformation in home heating systems, as the UK aims to eliminate gas boilers by 2035 to reduce carbon emissions. The main contender for replacing gas boilers is the heat pump due to its high efficiency, converting one unit of energy into about three units of heat. However, the transition is not straightforward. Heat pumps operate at lower water temperatures, necessitating larger radiators and better insulation, which can increase costs. While heat pumps are more energy-efficient, electricity costs about three times more than gas, partly negating the efficiency gains.
The Naga Students' Federation (NSF) has raised concerns about the environmental impact of the recent launch of a mega palm oil plantation drive in Nagaland. The NSF has raised concerns about the following potential impacts of the palm oil plantation drive:
As scorching heat waves grip the Southern and Southwestern United States, and temperatures soar across the Northern Hemisphere, NASA scientists have issued a warning that the worst of El Niño is yet to come. The experts predict that next year, 2024, could be even hotter due to the influence of El Niño, a natural climate pattern in the tropical Pacific that brings warmer sea-surface temperatures and affects weather patterns. Gavin Schmidt, Director of the NASA Goddard Institute for Space Studies, clarified that while El Niño has only recently emerged and is not solely responsible for the current extreme heat, the overall warming trend is primarily driven by climate change resulting from the burning of fossil fuels.
