Climate change is nowadays a greatest threat for humanity and environment
Climate change is basically a change of weather pattern that lasts for and extended period of time it cause by many factors including biotic and abiotic factors
Global Warming- Global warming of is one of the hot topic nowadays its the main reason of climate change earth has warmed remarkably over the last hundred years global warming is the increase of earth average temperature in troposphere which results in change in global climate pattern
Some of the biotic factors are volcanic eruption, plate tectonics movement and solar radiation beside this some of the abiotic factors are exploitation of natural resources, increase in population and pollution
Climate change has divided into two main causes such as
(1) Natural causes-The climate of earth that can affect by natural factors that are external to the climate system such as changes in volcanic activity,solar output and the earth orbit around the sun
(2) Anthropogenic causes- Climate change is also caused by human activities such as burning of fossil fuels,deforestation or conversion of land for economic and agricultural activities and its the main cause of climate change due to this ozone layer which is the protective layer of earth started depleting by the increase of chlorofluorocarbons (CFC)which increase the risk of ill effects in human body and increase in global temperature also known as Global Warming
Global warming can occur by natural factors but the main cause is Anthropogenic factors cause by human being such as Deforestation and Increase in use of fossil fuels
Impacts or Effects of global warming
Due to increased in earth temperature artic and Antarctic region iceberg and glacier started melting which affect the habitat of certain fauna or animal living in this region such as Polar bear, Penguin, Orca whales and seal etc.The North section of the Larsen B iceself in Antarctica a section larger than the state of Rhode Island collapsed between January and March 2002 distintegrating at the rate that astonished scientists.According to NASA scientists the polar ice caps is Melting at alarming rate of 9 percent per decade
(2) Rise in Sea level
Rising temperature are Warming ocean which expand as the temperature increases.This thermal expansion was the main driver of global sea level rise for 75-100 years after the start of industrial revolution some examples are Submersing of low lying land of Jakarta Indonesia
(3) Change in ocean current
A new study by the University of Pennsylvania Irina Marinov and Raffaele Bernardello and colleagues from McGill University have found that recent climate change may be acting to slow down one of these conveyer belt with potentially serious consequences for the future of the planet climate example are Dead of marrine fishes
Climate change can affect species in very large number of floura and fauna including the expansion, contraction, and “migration” of habitat; increased incidence of disease and invasive species; changes in temperature, precipitation, and other environmental conditions; shifts in food availability; and failure of ecological relationships may increase in extinction of biodiversity
(5)Human health
Climate change affects human health in a variety of ways. Extreme changes in the weather and environment can increase health problems in mental and physical factors such as asthma,skin disease,head stress,diarrhea, malnutrition and malaria
(6) Climate
The main affect of global warming is climate changeMore frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and Warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people's livelihoods and communities. As climate change worsens, dangerous weather events are becoming more frequent or severe.
Steps or action that can control global warming are
(1) Planting trees
A single tree will absorb one ton of carbon dioxide over its lifetime.
(2)Use of eco-friendly products or steps
Such as reduce the use of plastic,Use of solar energy
(3)Recycle more
We can save 2,400 pounds of carbon dioxide per year by recycling just half of your household waste.
Global warming is the major challenge for our global society. There is very little doubt that global warming will change our climate in the next century. ... If implemented now, a lot of the costs and damage that could be caused by changing climate can be mitigated and save or earth from destruction.
