Natural disasters are natural occurrences that result in harmful effects to both humans and the atmosphere. Humans activities trigger the natural disasters to occur. Nowadays we are told global warming causes natural disasters like floods, wildfire, hurricanes, Tornado, Droughts and typhoon. This theory states that human emissions of CO2 cause catastrophic, irreversible warming of our planet earth.
Regarding the natural disasters such as droughts, floods, and natural weather patterns have been existence in the geological record as well as since the historical record for 10,000 years. Erosion, and rising, and receding ocean levels are evident in land formation. These are not man-made emissions of CO2, but humanity plays a big part with urban heat islands causing temperature inversions which meet lowered jet stream and trade winds when there is solar flare activity putting pressure in the atmosphere for a perfect storm causing more advection, tornadoes, lightning, the wind, weather anomalies and precipitation.
Global warming is one of the biggest scientists concern. This term is used to describe increase in the earth’s temperature and this process continuously warming the earth. In the past three decades the earth’s surface has risen by about one degree Fahrenheit in the past century. For the last fifty years there is evidence that human actives cause the increase in the earth’s temperature.
Global warming is caused by a build-up of greenhouse gasses in the atmosphere which is resulted from human activities that have changed the chemical combustion of the environment and the atmosphere.The gasses realised to the environment include methane, nitrous oxide and carbon dioxide which are trapped in the earths surface.
The emissions of the greenhouse gasses is multiplying over time due to the technology growth, that has been perfected by humans like, factories which realises dangerous gasses such as carbon dioxide, methane , and nitrous oxide and ozone depleting substances such as, Per-flourocarbons, chlorofluorocarbons and Hydro-fluorocarbons.
Effects of global warming
It causes the occurance of additional pressure and meticulous illness to human health. Loss of life is direct from tremendous warmth. Warm temperatures argument water and hair pollution which harm human health in turn.
Varying climate is augmented to both rainfall and evaporation in main regions of the united states. In area with high evaporation,more soils will turn out to be drier, rivers will bear less water, and lake levels will drop than areas with rainfall which affects water resources. Lake levels and inferior river flows will damage map-reading, water quality, hydroelectric power generation and decrease water accessibility for resindential, agricultural and industrial uses.Human CO2 emmition cause natural disasters.
