Last Sunday, Vaniel, Christella Coeur-Aimable and I talked about current consequences of climate changes, particularly on deforested environment in Part I of our radio talk show on www.haimusique.com
One of the intelligent ways to comprehend the problematic of climate changes is by concurring that the earth is undergoing that phenomenon, by searching for the causes, identifying health effects associated with it (among others) and seeking ways to deal with it; while taking comprehensive and sustainable actions to minimize future outcomes on human and other ecological populations.
Pictures taken within the last 30 years illustrate a significant reduction of the polar ice cap, an increase of the globe's temperature (global warming)along with an average of the sea level. As a natural phenomenon, climate changes have recently been accelerated and its change in atmospheric compositions are widely thought to be due to human activities.
We (Vaniel, Kris and I) talked about the three major factors that influence the earth's climate more than all others combined: the sun, the atmosphere and the ocean. (Although we had some translation difficulties), we analyzed the contribution of the greenhouse gases towards the "global warming potential". Of course CO2 is identified as a "weak greenhouse gas" but the amount releases into the atmosphere through fossil fuel combustion (about 82% of all greenhouse gases) makes it one of the most "dangerous" enemy of the globe.
In the Haitian context, we analyzed the outcomes of deforestation towards the immediate effects of climate changes in that environment. The lost of "canopy cover" and "rhizomatous biomass" are directly correlated with an increase in "water velocity" (rivers, tributaries, chanels, etc.), in lost of cultivable soil, wildlife habitat, an increase of erosion, sedimentation, among others.
In Part II (next Sunday), we will focus on health impacts and ways to deal with climate changes.
