Renewable energy are energy resources whose use can be sustained over a long period of time. Most renewable source of energy are clean and emit little to no pollution.
Renewable energy are usually not easily depleted. They are known to:
decrease reliance on fossil fuels because they offer an alternate source of energy.
improve air quality because the produce little to no emission to the environment compared to the use of fossil fuels.
reduce habitat destruction in that they do not affect or alter the environment in any way. Global warming is one of the leading cause of climate change which significantly leads to habitat destruction.
the use of renewable resources can lead to reduction in health problems because the environment becomes healthier.
reduction in pollution owing to the cut in the use of fossil fuels.
Climate oscillation or climate cycles are a recurring oscillation within the global or regional climates and their fluctuations produce varying climatic cells and pressures often occurring on an interannual and multi annular basis.
On a decadal and millennium timescales.Current examples of the ENSO, Pacific oscillation, Antarctica, and arctic oscillation. like ENSO is characterized by flooding and drought conditions and the distribution of extreme conditions in the form of heat and cold waves.
Other cycles like the Piora oscillation, Little ice age, medieval warm period, retreating of glaciers and warming of the planet. All these cycles move on earth from the equator to tropics to temperate to polar areas and the continuous warming and cooling periods have altered the rate of spreading of the seafloor and oceanic basin.
Present warming has drastically created a major change in the evolution of species causing extinction and quick decomposition of resources. The release of carbon and methane gases over these years have raised the greenhouse effect at alarming rates.
