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?
Canada has instituted a price on carbon of $10 Canadian dollars per tonne of carbon dioxide, which would rise by $10 per year to reach a set price of $50 by 2022. In doing so, Canada has set a price on carbon, the necessary first step to implementing a carbon tax or a cap and … More Setting a price on carbon for implementing a carbon tax or a cap and trade system for controlling carbon dioxide emissions
Oceans absorb some of the carbon dioxide and heat released by human activities, such as fossil fuel combustion for energy production and derivation of petrochemical products useful in many aspects of daily life. Specifically, carbon dioxide dissolves in water to form carbonic acid, a weak acid that increases the acidity of ocean water. Increase in … More Absorption of carbon dioxide and heat by the oceans, but would that be enough?
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
Renewable energy such as those from wind, tides and solar typically have higher production cost compared to electricity from oil, coal and gas, with coal being the cheapest fuel source for conventional power plants. With the emphasis on reducing air pollutants from fossil fuel fired power stations and the importance of lowering carbon dioxide emissions … More Overabundance of renewable energy and the removal of feed-in tariffs
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
