Carbon budget and carbon inventory: can we still use fossil fuels?

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?

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

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

Climate sensitivity and how close are we to dangerous anthropogenic interference in climate change?

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?

Absorption of carbon dioxide and heat by the oceans, but would that be enough?

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?
