Climate change otherwise known as global warming has been an ongoing issue for decades. Beginning in the 19th century, climate change has increasingly affected Earth and its atmosphere. Rising levels of carbon dioxide are warming the Earth’s atmosphere causing rising sea-levels, melting snow and ice, extreme fires and droughts, and intense rainfall and floods. Climate change has and will continue to affect food production, availability of water, and can add to many health risks in humans and animals. In fact, in an article by Justin Gillis titled, “Scientists Warn of Perilous Climate Shift Within Decades, Not Centuries” he focuses on a paper written by former NASA climate scientist, James E. Hansen, explaining the effects of climate change
This makes it difficult to maintain carbon dioxide concentrations and the greenhouse effect occurs, increasing world temperatures and altering weather patterns. Deforestation of the Amazon accounted for 1.5 % of the increase in carbon dioxide levels since the mid 19th century. Also, sea levels rise, and polar ice caps melt, causing habitat loss and catastrophic calamities in the
Ecosystems are already showing negative impacts under current levels of climate change. This essay will argue that climate change is a huge threat to biodiversity and will also focus on the natural cycle and the modern day cycle change. Firstly, it will define and discuss the natural climate change cycle. Then secondly, it will analyse the effects of human activities on the climate that are rapidly changing it. Finally, it will examine the effect climate change had the now extinct Golden Toad.
A combination of climate change, pollution and search for natural resources is threatening the fragile species and ecosystems within the Arctic region. Over the last two centuries the world's global mean temperature has increased by 0.6 degrees, noting this continuous change in global temperatures is too accelerated for the natural environment to adapt to. Much of this change in global temperatures is the result of c02 emissions being released into the atmosphere. Currently, 80% of the world's growing energy demands are met by the burning of fossil fuels which emit astonishing amounts of c02 into our atmosphere (3). As the name suggests, climate change references the change of the climate, unfortunately this is not limited to the fragile systems of
There are many things that happen during climate change. The oceans are warming leaving the glaciers to melt, and overall the world’s natural state is disappearing. If that wasn’t enough, the population is constantly growing. ‘Human activity is causing irreversible harm to the climate system and environment’ so it should be up to each human to help to combat it and adapt to it. (Cao, 2008).
This is changing the natural systems that take place in our atmosphere. When all these extra gases are released, carbon dioxide stars to accumulate in the atmosphere. Climate change is a global issue because when the temperature of the Earth changes even very slightly, it can cause droughts and our crops can die. This is affecting our food supply. Also, when water levels rise even slightly, it can be very destructive for
Extinction provides the human species with a different perspective. Research in the field, uncovers possible factors causing the destruction. With this knowledge, the human ascertains how to avoid extinction and how to well upkeep earth. In Twilight of the Mammoths; Overview of Overkill Martin argued that radiocarbon and other geological methods of dating proves through a correlation that human migration caused the extinction of species during the Quaternary period. The "overkill" effect of humans instigated an ecological shock misbalancing the equilibrium.
Due to pollution, air quality is already poor. The deficiency of all of these factors will inevitably affect humans negatively. In order to protect the pollinators, the environment, and mankind, we must reformulate pesticides or cease the use of them altogether. Dr. Fairbrother, a renowned scientist and former member of the Environmental Protection Agency, noted that commercial bee-keeping companies reported losses of up to ninety percent of their colonies in 2006 (719). Scientists are blaming the losses on Colony Collapse Disorder.
It occurs due to rise in global warming which occurs due to increase in temperature of atmosphere by burning of fossils fuels and release of harmful gases by industries. Climate change has various harmful effects but not limited to melting of polar ice, changes in seasons, occurrence of new diseases, frequent occurrence of floods and change in overall weather scenario. • Loss of Biodiversity: Human activity is leading to the extinction of species and habitants and loss of bio-diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Balance of natural processes like pollution is crucial to the survival population is decimating.
Deforestation is quickly becoming one of the biggest environmental problems in the world. Deforestation is often done by humans for land development, roads and railroads, and other economic reasons. Around eighteen million acres of forest is lost each year, causing serious repercussions. We should reduce tropical deforestation because it causes the extinction of species, soil erosion, and climate change. One of the leading causes of extinction is deforestation.
