Brown Carbon and Global Warming 2023

Black carbon refers to the particulates generated by the combustion of fossil fuels such as gas, coal, and oil. However, scientists believe that brown carbon, a lesser-known type of compound, may also contribute to global warming. When discussing global warming and greenhouse gas emissions, CO2 and methane are frequently mentioned. However, brown carbon is another substance that scientists are particularly concerned about. These organic substances, also known as "tarballs," appear as aerosols and have the ability to absorb certain wavelengths of solar radiation. The overwhelming majority of brown carbon originates from the combustion of biomass. It can, for instance, be produced by forest fires. In recent years, brown carbon has been the subject of numerous investigations. ...

Climate change likely contributed to early Andean population violence 2023

Wildfires and shorter staple crop growth seasons due to climate change have economic repercussions. As temperatures rise, researchers expect and witness more interpersonal violence and fatalities. Climate change violence is historical. UC Davis researchers observed a trend of increasing violence during climate change in the south central Andes between A.D. 470 and 1500. During the Medieval Climatic Anomaly (900-1250), temperatures soared, drought prevailed, and the first Andean nations disintegrated. A recent report suggests that climate change and competition for few resources in the south central Andes may have caused highland violence. "We found that decreased precipitation predicts increased rates of cranial trauma," said Thomas J. Snyder, the study's lead author and a doct...

International Mount Everest Day: Mountain communities urgently decarbonize Everest 2023

An intergovernmental organization protecting the Hindu Kush Himalaya (HRH) warns that global warming is changing Mount Everest seven decades after Edmund Hillary and Tenzing Norgay first climbed it. According to a news conference by Nepal's International Centre for Integrated Mountain Development (ICIMOD), human activity has pushed Earth's systems near to tipping points that would make living difficult. Global warming threatens Everest and the Hindu Kush Himalaya (HKH), which spans 3,500 km across eight nations. Mountain communities, climbers, and scientists demanded climate change action from international leaders. Under the present emissions scenario, two-thirds of the region's glaciers will disappear in 70 years, ICIMOD added. ICIMOD predicts that climate change would w...
