Episode 26: Carbon sequestration

Send a textIn this episode of the podcast, I have talked about "Carbon sequestration".Topics:What is Carbon sequestration?Oceanic Carbon sequestrationGeologic Carbon sequestrationTerrestrial Carbon sequestrationCarbon Sources and Carbon SinksClimate Change MitigationCarbon sequestration in grasslandsCarbon sequestration in soilsAdditional Info: Human induced carbon pools are characterized with Carbon capture and storage (CCS) technology. Carbon capture and storage is a combination of technologies and techniques that enable the capture of CO2 from fuel combustion or industrial processes. Then transportation of CO2 is being done through pipelines, CO2 is stored underground in depleted oil and gas fields and deep saline formations. CCS can, therefore, have a unique and imperative role to play in a sustainable low-carbon economy.  This is caused primarily by increases in “greenhouse” gases such as Carbon Dioxide (CO2).   Small changes in the average temperature of earth so far, can transform into large in coming hundred years. Moreover, these climatic changes will have great potential to create negative impacts on environment and mankind. Therefore, it is essential to mitigate climate change for advance minimization of its dangerous impacts. Current evidence suggests that to avoid the worst impacts of climate change, we should aim to limit the global average temperature rise to 2°C (35.6°F), not beyond that. This requires to undertake immediate reduction in global greenhouse gas emissions in all the sectors.  All extra carbon dioxide in the atmosphere is increasing the overall temperature of earth on day-to-day basis, causing global warming. It is changing climate in unpredictable ways, from floods and hurricanes to heat waves and droughts. To try and reduce the risk of global warming and extreme weather events, It is required to reduce the amount of how much fossil fuel we are burning. This isn't an easy process. In the 1997 Kyoto Protocol, it was decided that carbon emission in the atmosphere will be reduced by 5% below 1990 levels between 2008 and 2012. Several measures can be found out to reduce carbon from the atmosphere and thus to reduce adverse impacts of climate change. One of the measure is carbon sequestration, which is cheap and simple as well as costly and complex. That is natural carbon sequestration and geological carbon sequestration.   Carbon farming is a name for a variety of agricultural methods aimed at sequestering atmospheric carbon into the soil and in crop roots, wood and leaves. Increasing soil's carbon content can aid plant growth, increase soil organic matter (improving agricultural yield), improve soil water retention capacity and reduce fertilizer use (and the accompanying emissions of greenhouse gas nitrous oxide (N2O). As of 2016, variants of carbon farming reached hundreds of millions of hectares globally, of the nearly 5 billion hectares (1.2×1010 acres) of world farmland. Soils can contain up to five per cent carbon by weight, including decomposing plant and animal matter and biochar.  The use of the technology would add an additional 1–5 cents of cost per kilowatt hour, according to estimate made by the Intergovernmental Panel on Climate Change. The financial costs of modern coal technology would nearly double if use of CCS technology were to be required by regulation.   Twitter: https://twitter.com/realyashnegiEmaBuzzsprout - Let's get your podcast launched!Start for FREEDisclaimer: This post contains affiliate links.
