Negative effects of global warming essay
It's not bad "Two thousand years of published human histories say that warm periods were good for people.
- Today, the policies of most countries favor the most intensive forms of transportation such as auto and air travel , and are biased toward conventional energy over renewables, and toward new energy supplies over efficiency measures.
- Loss of animal and plant habitats.
- Cultural or heritage sites destroyed faster due to increased extremes.
Agriculture While CO2 is essential for plant growth, all agriculture depends also on steady water supplies, and climate change is likely to disrupt those supplies through floods and droughts. It has been suggested that higher latitudes — Siberia, for example — may become productive due to global warming, but the negative effects of global warming essay in Arctic and bordering territories is very poor, and the amount of sunlight reaching the ground in summer will not change because it is governed by the tilt of the earth.
Agriculture can also be disrupted by wildfires and changes in seasonal periodicity, which is already taking place, and changes to grasslands negative effects of global warming essay water supplies could impact grazing and welfare of domestic livestock.

Increased warming may also have a greater effect on countries whose climate is already near or at a temperature limit over which yields reduce or crops fail — in the tropics or sub-Sahara, for example. Health Warmer winters would mean fewer deaths, particularly among vulnerable groups like the aged. However, the same groups are also vulnerable to additional heat, and deaths attributable to heatwaves are expected to be approximately five times as negative effects of global warming essay as winter deaths prevented.
- In , the average global temperature was the third highest ever recorded, just slightly below the and averages.
- Change the time and seasons and birds are flying south for winter sooner, hibernation takes longer, and a whole series of events is set in motion for complete collapse of animal life.
- Large scale evaporation will be the major cause of droughts in many places particularly Africa.
Polar Melting While the opening of a year-round ice free Arctic passage between the Atlantic and Pacific oceans would confer some commercial benefits, these are considerably outweighed by the negatives. Detrimental effects include loss of polar bear habitat and increased mobile ice hazards to shipping.

The loss of ice albedo the reflection of heatcausing the ocean to absorb more heat, is also a positive feedback; the gloal waters increase glacier and Greenland ice cap melt, as well as raising the temperature here Arctic tundra, which then releases methane, a very potent greenhouse gas methane is also released from the sea-bed, where it is trapped in ice-crystals called clathrates. Melting of the Antarctic ice shelves is predicted to add further to sea-level rise with no benefits accruing.
Ocean Acidification A cause for considerable concern, there appear to be no benefits to the change in pH of the oceans. This process is caused by additional CO2 being absorbed in the water, and may have severe destabilising effects on the entire oceanic food-chain.
Sea Level Rise Many parts of the world are low-lying and will be severely affected by modest sea rises. Rice paddies are being inundated with salt water, which destroys the crops.
The Administration also argued that the treaty does not require developing nations to curb their emissions. Almost everyone is vulnerable to the effects of weather-related disasters, but people in poor countries face a far greater threat due to risk factors that include inadequate housing located on flood plains and steep hillsides, weak healthcare systems, and heavy economic dependence on agriculture. There is some evidence that the water in the North Atlantic seems to be growing less salty negxtive to global warming and that the conveyor belt may be slowing. But humans can move and adapt far more easily than most other species, and are unlikely to be wiped out—even by abrupt changes. Someone else might face losing her home or even life in a catastrophic weather disaster made worse by global warming. Earlier drying of effectz leading to increased forest fires in size and intensity. Another important way to act on climate change is by voting and supporting candidates who are serious about reducing greenhouse gas emissions.
Seawater is contaminating rivers as it mixes with fresh water further upstream, and aquifers are becoming polluted. Given that the IPCC did not include melt-water from the Greenland and Antarctic ice-caps negayive to uncertainties at that time, estimates of sea-level rise click feared to considerably underestimate the scale of the problem.
There are no proposed benefits to sea-level rise.

negatiive Environmental Positive effects of climate change may include greener rainforests and enhanced plant growth in the Amazon, increased vegitation in northern latitudes and possible increases in plankton biomass in some parts of the negxtive. Negative responses may include further growth of oxygen poor ocean zones, contamination or exhaustion of fresh water, increased incidence of natural fires, extensive vegetation die-off due to droughts, increased risk of coral extinction, decline in global photoplankton, changes in migration patterns of birds and animals, changes in seasonal periodicity, disruption to food chains and species loss.
Economic The economic impacts of climate change may be catastrophic, while there have been very few benefits projected at all. The Stern report made clear the overall pattern of economic distress, and while the specific numbers may be contested, the costs of climate change were far in excess of the costs of preventing it. Certain scenarios projected in the IPCC AR4 report would witness massive migration as low-lying countries were flooded.
Disruptions to global trade, transport, energy supplies and labour markets, banking and finance, investment and insurance, would all wreak havoc on the stability of both developed and developing nations.
Cultural or heritage sites destroyed faster due to increased extremes. Ocean Acidification A cause for considerable concern, there appear to be no benefits to the change in pH of the oceans. Increased precipitation in the form of rain have already been noticed in polar and sub-polar regions. What is the Kyoto Protocol and what can it do to curb climate change?
Markets would endure increased volatility and institutional investors such as pension funds and insurance companies would experience read article difficulty. Developing countries, some of which are already embroiled in military conflict, may be drawn into larger and more protracted disputes over water, energy supplies or food, all of which may disrupt economic growth at a time when developing countries are beset by more egregious manifestations of climate change.
It is widely accepted that the detrimental effects of climate change will be visited largely on the countries least equipped to adapt, socially or economically. Basic rebuttal written by GPWayne Update July Here is a related lecture-video from Denialx - Making Sense of Climate Science Denial.
And landfills release methane into the air as our garbage decomposes. With such a vast eruption in the animal kingdom, our own world becomes in danger. Sea Level Rise Many parts of the world are low-lying and will be severely affected by modest sea rises. What are some of the impacts we can expect from climate change? Effect of Effecrs Warming on Animals Essay Effect of Global Warming on Animals Essay Words 3 Pages Show More Global warming is one of the most serious problems that people all over the world are dealing with. Likewise, we do not know exactly what the impacts of climate change will be on particular countries or regions. Governments can also increase investments in public transportation and encourage development patterns that minimize sprawl. Deserts get drier leading to increased desertification.
