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

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

Faster than estimated retreat of glaciers on the East Antarctic Ice Sheet

Feature article in Nature, Vol. 544, Issue 7649, 13 April 2017, pp. 152-154, “The threat beneath Antarctica”   Summary of article: Although the retreat of glaciers on the West Antarctic Ice Sheet is commonly thought to be faster than those on the larger East Antarctic Ice Sheet, new observations have showed that Totten glacier on … More Faster than estimated retreat of glaciers on the East Antarctic Ice Sheet

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?

Setting a price on carbon for implementing a carbon tax or a cap and trade system for controlling carbon dioxide emissions

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

Understanding past climate from bubbles trapped in ice cores

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
