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
Winters are shorter and temperature fluctuations between seasons are more extreme. More importantly, it has been scientifically proven that Earth is warming as measured by average surface temperatures. With a warming trend that is unlikely to be abated, significant changes will occur in atmospheric circulation and temperature resultant from a progressive increase in average carbon … More Climate sensitivity and how close are we to dangerous anthropogenic interference in climate change?
NASA’s upcoming Insight’s mission is a lander designed to probe the seismic environment of Mars. Equipped with a seismometer, the mission’s main scientific objectives is to understand the geological activity of present day Mars, a goal that is on the one side, controversial, but on the other, useful and with an expensive price tag. … More Probing a geological question on Mars: What is the correct price for a robotic scientific mission to another planet?
Hydropower produced by turbines from water flowing down a large reservoir retained by a dam is one renewable energy source tapped by countries endowed with rivers traversing a terrain with large elevation changes. Often touted to be clean, non-polluting and sustainable, hydroelectric power generation does have environmental concerns, primarily in the area of impacting the … More Unaccounted for greenhouse gas emissions from hydroelectric power plants
