The Amazon forest system is facing a critical juncture that could lead to a drastic collapse, causing widespread alarm worldwide. Throughout its 65 million year history, the Amazonian forests have shown remarkable resilience to climatic changes. However, the region is now under unprecedented stress due to factors such as rising temperatures, severe droughts, deforestation, and…
In order to make transportation more environmentally friendly, new inventions and creative adaptations are essential in order to decarbonize the sector. According to the Intergovernmental Panel on Climate Change, around 15 percent of net anthropogenic greenhouse gas emissions come from the transportation sector. It is crucial to find ways to transport people and goods from…
A new study published in a scientific journal reveals that progressive thinning of Antarctic ice shelves has been observed since 1973. The mass loss of the Antarctic Ice Sheet is mainly attributed to the reduction in thickness of floating ice shelves that surround the ice sheet. This thinning weakens the buttressing potential of the ice…
Fertilizer management plays a crucial role in reducing global ammonia emissions from crop production, which threatens air quality, human health, and ecosystems. However, accurately estimating these emissions is challenging due to limited data, hindering the ability to identify effective mitigation strategies. To address this issue, researchers have developed a machine learning model that provides crop-specific…
