Ice transport drives salinity changes in the Southern Ocean

Article in Nature, Vol. 537, Issue 7618, pp. 89, “Sea-ice transport driving Southern Ocean salinity and its recent trends”   Summary of article: Northward movement of sea ice and freshening of the northern sectors of the Southern Ocean around Antarctica has been shown to account for the observed salinity distribution change in the area. The … More Ice transport drives salinity changes in the Southern Ocean

Definition of Anthropocene

Multiple epochs define human civilisation evolution throughout the ages. But, according to scientific studies, the influence we have had on our planet has led to the definition of a new epoch in human civilisation, the Anthropocene. Specifically, given that humans have wielded significant influence on the planet, primarily through industrial revolution and the attendant evolution … More Definition of Anthropocene

Satellite imagery of clouds reveals evidence of climate change

Article in Nature, Vol. 536, Issue 7614, pp. 72-74, “Evidence for climate change in the satellite cloud record” Summary of article: Using climate modelling specific for predicting cloudiness and satellite records of cloud cover, the reasons underlying recent decadal changes in cloud cover and movement of storm tracks was uncovered, with greenhouse gas emissions, as … More Satellite imagery of clouds reveals evidence of climate change

Antarctica McMurdo research station

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

Vegetation’s response to global warming

Article in Nature, Vol. 531, Issue 7596, pp. 633-636, “Boreal and temperate trees show strong acclimation of respiration to warming”   Summary of article: Using statistical analysis of a large sample of temperature response curves obtained by measuring carbon dioxide loss from leaves in simulated temperature changes, the study opens our eyes to the role … More Vegetation’s response to global warming

Floating offshore wind farms add flexibility to a renewable energy resource but power transmission to land is a challenging problem

A recent article in Guardian (Link) reports the imminent deployment of a floating offshore wind turbine farm off the northeast coast of Scotland. Compared to conventional wind turbine with moorings on the seabed, floating offshore wind turbine farms are built on large floating structures, and enable windfarms to be deployed at longer distances off the … More Floating offshore wind farms add flexibility to a renewable energy resource but power transmission to land is a challenging problem

Fuel efficiency standards’ roles in reducing greenhouse gas emissions and air pollutants

Fuel efficiency first come to the fore of car buyers’ minds when Japanese carmakers successfully produced highly fuel efficient compact cars that gained significant market share in developing countries’ markets, followed later, by more developed economies such as the U.S. and Europe. This phenomenon of fuel efficient vehicles, where Japanese models, in the 1980s, used … More Fuel efficiency standards’ roles in reducing greenhouse gas emissions and air pollutants

Carbon dioxide emissions continue to increase and has not stabilized

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

Peatland occupies 3% of the world’s surface but holds twice of the carbon stored in biomass on Earth

Peatland, or partially decomposed organic matter, comprises 3% of the world’s land surface area, but holds about twice the total amount of carbon stored in biomass on Earth. This explains why there has been so much attention on the protection of the world’s peatland such as those in the Arctic permafrost zone as well as … More Peatland occupies 3% of the world’s surface but holds twice of the carbon stored in biomass on Earth
