“Should you and I as members of the human race be preparing for doomsday brought on by the abrupt climate change, and if so, what should we be doing about it?”
...e raising of salinity concentrations there, and transporting more fresh water vapour by means of the atmosphere towards the Earth’s poles. These rapid oceanic changes suggest that the latest climate changes, including global warming, may be causing a variation in the original planetary system which normalizes evaporation and precipitation, and the rotation of fresh water around the globe. An increase of the Earth’s global water cycle can have potential effects on global precipitation patterns that run the circulation, harshness, and the regularity of storms, floods, and droughts. This would worsen the effects of Global Warming by rapidly adding more water vapour, which is already a potent, heat- trapping greenhouse gas, to the atmosphere. This may result in the continuation of the freshening of Northern Atlantic Ocean waters, to the point where ocean circulation could be disrupted, and where further climate changes may be triggered. Evaporation concentrates salt in the surface ocean, increasing evaporation rates which cause obvious spikes in surface ocean salinity levels. In turn, salinity decreases usually reflect the addition of fresh water to the ocean through precipitation and runoff from the continents. Conveyors, which are global ocean circulation systems, help to draw warm Gulf Stream waters northward in the Atlantic, pumping heat into the northern regions that drastically restrains wintertime air temperatures, especially in Europe. The global ocean circulation system, often called the Ocean Conveyor, transports heat throughout the planet. The Conveyor could slow down if the North Atlantic Ocean becomes too fresh, and this would result in the discontinuation of its sinking waters. The analysis of deep- sea sediment, ice cores, as well as other geologic evidence, have undoubtedly confirmed that the Conveyor has abruptly slowed down many times in Earth’s history. Thus, it has caused the cooling of the North Atlantic region, and has carried long- term drought conditions to other areas of the Northern Hemisphere, over periods as short as years to decades. The cooling of the North Atlantic region would delay the melting process, restrain the entry of fresh water to the North Atlantic, and the Conveyor would begin to circulate ocean waters again. Global warming and an increased water cycle would continue to bring fresh water to high latitudes, possibly enough in order to maintain a cap on the Conveyor, even if the Arctic melting ended. The Earth’s hydrological cycle is vital because of it’s near- term impacts on the Earth’s climate. "Dig the well before you are thirsty." - Chinese proverb This proverb suggests that prevention is always better than cure. This means that we should try our best to prevent the variation, and to stop the varying climatic conditions. One of the ways in which this can be achieved is by decreasing the amount of forest destruction that takes place. Trees play huge roles in the global carbon cycle, and are the largest land- based natural means of removing carbon dioxide (CO2) from the air. Trees store large amounts of CO2 in their construction. When trees are burned, the carbon locked up in their structures is released into the air in the form of CO2. Today, the miniscule world forests are unable to absorb all of the CO2 created by humans while burning fossil fuels. Another reason for the rapid increase in Global Warming is because of the population growth. Technology is partially responsible for the damage caused to the Earth’s resources, and for the unpredictable population growth. The Industrial Revolution caused a rapid increase in population growth, a soil and gas fuels were exploited for our use. There is an obvious trend between the problems of global warming and overpopulation, as the increase in levels of CO2 follows the growth in population. Today, we have an...
