Climate change has converted to a multi-faceted predicament- by- Naseem Sheikh

The most current report from the International Panel on Climate Change (IPCC) (drafted on Aug. 7, 2019) highlights the vulnerability of global food sanctuary to deviations in climate and land use. The report emphasized that adaptive strategies to reduce total carbon production and preserve natural ecosystems are humanity’s best chance at mitigating the climate emergency’s effects on food production.   The report stressed the extent of human dependency on land systems. Humans are currently using one quarter to one third of available land’s potential production capacities. Essential products that come from land use, including feed and natural energy sources such as fossil fuels, are crucial to agricultural yields and the sustainability of the food supply chain. Land degradation is a general term describing negative trends in land condition, such as loss in biological productivity and ecological value to humans, Civilization is consuming assets at an exceptional degree.

Peatlands trap carbon dioxide, even during droughts

Although peatlands make up only 3 percent of the Earth’s surface, they store one third of the soil carbon trapped in soils globally. Preserving peatlands is therefore of paramount importance for mitigating climate change, provided that these vulnerable environments are not themselves threatened by global warming. To better determine this risk, two French scientists, including Vincent Jassey, a CNRS researcher at the Laboratoire Ecologie Fontionnelle et Environnement (CNRS/Université Toulouse III—Paul Sabatier/INP Toulouse), studied carbon uptake by the two main species of moss that make up the Le Forbonnet peatland in Frasne (Jura). They discovered that when temperatures were high and also during droughts, the two Sphagnum species behaved in opposite ways: Sphagnum medium resists drought, whereas the photosynthesis of Sphagnum fallax is negatively impacted; conversely, in very hot but humid weather, photosynthesis, and thus carbon uptake, in Sphagnum fallax increases, whereas t...

Carbon dioxide: Main culprit of global warming like Methane

IS CO2 main culprit of global warming or not? Recently this is very debatable topic, one group says CO2 is a normal gas like hydrogen, nitrogen and oxygen and not a reason of recent global warming but there is group of believers that admit CO2 as culpable and I am believer of second group. To satisfies them I have a small logical reason as in our surrounding we have a large number of nutrients but not all of equal importance, few are micro and other are macro similarly their ratio in our diet matters a lot. If one exceed its normal limit cause in ill factor of body functioning. Similarly CO2 is main culprit for causing global warming due to presence of carbon which is main building block of nature and nature believes on balance of every thing. Carbon dioxide (CO2) is a slightly toxic, odourless, colourless gas with a slightly pungent, acid taste. it is currently occurring at an average concentration of about 390 parts per million by volume or 591 parts per millio...
