DEFINITION OF CLIMATE
Climate change can be defined as the regular pattern of weather conditions of a particular place. It can also be defined as a general attitude of feeling of an atmosphere or a situation which exists in a particular place.therefore climate change is a global phenomenon of climate transformation characterized by the change in usual climate of the planet that are especially caused by human activities.climate Change can unbalance the whole earth.
CAUSES OF CLIMATIC CHANGES
There are so many things that causes change in the climate but below are just the few major causes of the changes in climate. They are;
First,the excessive use of fossil fuels such as coal,oil and gas to generate electricity, run cars and power manufacturing and industry through emission of smokes into the atmosphere can damage the ozone layer and cause global warming.
-Secondly, deforestation;the process of cutting trees.this can cause global warming because trees help to absorb energy and store carbon dioxide and also protect the surface of the earth from the direct sun shine.
-Additionally,solar radiation,the sun is the main source of supply of energy to the earth and when there's change in the output of the sun energy can lead to climate change. When this changes occurs to the sun ,the climate becomes hotter/warmer during periods of stronger solar intensity.
-Finally, climate change can be curtailed through the use of renewable energies such as solar ,wind and geothermal etc. thereby reducing the use of fossil fuels.climate change can be reduced through energy and water efficiency I .e producing clean energy by using more efficient devices like LED lights bulbs and innovative shower system,which is less costly and important.
EFFECTS OF CLIMATE CHANGE
The following are the effects of the changes in climate. They are;
More frequent and severe weather
Higher temperatures are worsening many types of disasters, including storms, heat waves, floods, and droughts. A warmer climate creates an atmosphere that can collect, retain, and drop more water, changing weather patterns in such a way that wet areas become wetter and dry areas drier. "Extreme weather events are costing more and more," says Aliya Haq, deputy director of NRDC's Clean Power Plan initiative. "The number of billion-dollar weather disasters is expected to rise.
Higher death rates
Today's scientists point to climate change as "the biggest global health threat of the 21st century." It's a threat that impacts all of us—especially children, the elderly, low-income communities, and minorities—and in a variety of direct and indirect ways. As temperatures spike, so does the incidence of illness, emergency room visits, and death.
Rising temperatures also worsen air pollution by increasing ground level ozone, which is created when pollution from cars, factories, and other sources react to sunlight and heat. Ground-level ozone is the main component of smog, and the hotter things get, the more of it we have. Dirtier air is linked to higher hospital admission rates and higher death rates for asthmatics. It worsens the health of people suffering from cardiac or pulmonary disease. And warmer temperatures also significantly increase airborne pollen, which is bad news for those who suffer from hay fever and other allergies.
Higher wildlife extinction rates
As humans, we face a host of challenges, but we're certainly not the only ones catching heat. As land and sea undergo rapid changes, the animals that inhabit them are doomed to disappear if they don't adapt quickly enough. Some will make it, and some won't. According to the Intergovernmental Panel on Climate Change's 2014 assessment, many land, freshwater, and ocean species are shifting their geographic ranges to cooler climes or higher altitudes, in an attempt to escape warming. They're changing seasonal behaviors and traditional migration patterns, too. And yet many still face "increased extinction risk due to climate change." Indeed, a 2015 study showed that vertebrate species—animals with backbones, like fish, birds, mammals, amphibians, and reptiles—are disappearing 114 times faster than they should be, a phenomenon that has been linked to climate change, pollution, and deforestation.
More acidic oceans
The earth's marine ecosystems are under pressure as a result of climate change. Oceans are becoming more acidic, due in large part to their absorption of some of our excess emissions. As this acidification accelerates, it poses a serious threat to underwater life, particularly creatures with calcium carbonate shells or skeletons, including mollusks, crabs, and corals. This can have a huge impact on shell fisheries. Indeed, as of 2015, acidification is believed to have cost the Pacific Northwest oyster industry nearly $110 million. Coastal communities in 15 states that depend on the $1 billion nationwide annual harvest of oysters, clams, and other shelled mollusks face similar long-term economic.
It's a very important thing that we should adhere to the rules and put at least if not a stop but a serious check on our environment. The causes of the changes in climate has been explained above so a serious rule should be implemented to see that we achieve our goal of curbing the problem.
