Climate change has prompted scientists and policy makers to fathom whether humanity should continue to rely on fossil fuels for energy production. Specifically, considering that a threshold of atmospheric carbon dioxide exists where there would be irreversible effects of climate change on the globe in what is known as dangerous anthropogenic interference (DAI), how much … More Carbon budget and carbon inventory: can we still use fossil fuels?
Climate change is resulting in the loss of significant amount of ice from glaciers and ice sheets around the world, especially at the polar regions where global warming’s pace is the fastest. Thus, there is a movement in the climate change research community in cataloguing ice cores from glaciers, both at mountains and on ice … More Preservation of ice cores from tropical snow capped mountains
Article in Nature, Vol. 533, 26 May 2016, pp. 527, “The role of low-volatility organic compounds in initial particle growth in the atmosphere” Summary of article: Using nitrate ion chemical ionization atmospheric pressure interface time of flight mass spectrometry, a particle growth model for organic aerosols was proposed and validated. Comment: Organic materials … More Role of organic particles in seeding growth of aerosols in the atmosphere
Article in Nature, Vol. 533, Issue 7604, pp. 521, “Ion-induced nucleation of pure biogenic particles” Summary of article: Nitrate ions are shown to induce formation of aerosols such as those seeded by α-pinene. Biogenic aerosols play important roles in influencing weather events through inducing the formation of clouds. Thus, by understanding their formation mechanisms … More Science underlying nucleation of biogenic particles
Article in Nature, Vol. 531, 24 March 2016, pp. 493, “The past, present and future of African dust” Summary of article: An excellent study on calibrating the effect of wind on topography using dust as an indicator of wind speed and wind fields, which yields important information on how African dust affects weather patterns … More How dust informs climate now, in the past and future
Antarctica is important in many ways other than its sheer scale of beauty for explorers, it is also rich in many areas of scientific research running from astronomy, cosmology, global warming, glaciology, climate change, sea level rise, social animal activities, etc. The United States run the largest scientific research station in Antarctica, McMurdo research station, … More Antarctica McMurdo research station
A recent New York Times article (Link) posits that carbon dioxide concentration in the atmosphere continues to increase, due to the failure of Earth’s oceans and vegetations at absorbing carbon dioxide in a scenario that carbon dioxide emissions have stabilized across the world. The pertinent time period is 2015 and 2016. My personal opinion … More Carbon dioxide emissions continue to increase and has not stabilized
Sky usually comes in blue, grey or dark color. But, there are times when the sky appears pink. Why is that so? Specifically, the phenomenon comes about through the interaction of light with the dust and soot particles high up in the atmosphere. When light hits a dust particle in air, it is scattered … More Why is the sky pink in the evening?
Parallel imports offer an easy and flexible path for car aspirants to own a car whose characteristics and vintage matched their specifications and dreams. From a commercial perspective, parallel imports afford a mechanism for exchange of cars with differential performance characteristics tailored to the road conditions of individual markets. Hence, parallel import adds to the … More Street level air pollution and excessive tailpipe emissions from old parallel imported cars
We know the past from a historical record of it written on paper, inscribed in stone, or from depictions of events entrapped in fossils. To understand past climates, scientists look for bubbles of past atmospheres trapped in ice cores as historical record of what happened. Typically, these ice cores could be obtained from three types … More Understanding past climate from bubbles trapped in ice cores
