From start to finish, factory farming is responsible for the abuse of land, animals, and natural resources all for the express purpose of providing cheap, unhealthy food to the large amounts of people. With rising concerns over food security and the future of our rapidly deteriorating environment, more attention has been put on the multitudinous ways factory farming contributes to these issues.
Attribution of recent climate change In this article, " climate change " means a change in climate that persists over a sustained period of time. Changes in climate may be due to natural causes, e.
Detection does not imply attribution of the detected change to a particular cause. NASA GISS The graph above shows the average of a set of temperature simulations for the 20th century black linefollowed by projected temperatures for the 21st century based on three greenhouse gas emissions scenarios colored lines.
This projection is relative to global temperatures at the end of the 20th century. Global surface temperature for the past 5. The lastyears are expanded in the lower half of the figure image credit: Physical impacts of climate change Seven of these indicators would be expected to increase in a warming world and observations show that they are, in fact, increasing.
Three would be expected to decrease and they are, in fact, decreasing. Each of the different colored lines in each panel represents an independently analyzed set of data.
The data come from many different technologies including weather stationssatellitesweather balloonsships and buoys. Some of the graphs show a positive trende.
Other graphs show a negative trend, e. Evidence of warming is also apparent in living biological systems. With medium confidence see footnote 1IPCC  concluded that human influences had contributed to an increase in heavy precipitation events at the global scale.
Projections of future changes in precipitation show overall increases in the global average, but with substantial shifts in where and how precipitation falls. Extremely hot nights have doubled in frequency. The area in which extremely hot summers are observed, has increased fold.
These changes are not explained by natural variability, and attributed by climate scientists to the influence of anthropogenic climate change. Heat waves with high humidity pose a big risk to human health while heat waves with low humidity lead to dry conditions what increase wildfires.
The mortality from extreme heat is larger than the mortality from hurricanes, lightning, tornadoes, floods, and earthquakes together  See also heat wave. Tropical cyclones At the global scale, the frequency of tropical cyclones will probably decrease or be unchanged.
Some impacts will be beneficial—e. Retreat of glaciers since A map of the change in thickness of mountain glaciers since Thinning in orange and red, thickening in blue. A map that shows ice concentration on 16 Septemberalong with the extent of the previous record low yellow line and the mid-September median extent black line setting a new record low that was 18 percent smaller than the previous record and nearly 50 percent smaller than the long-term — average.
The cryosphere is made up of areas of the Earth which are covered by snow or ice. Assuming high growth in greenhouse gas emissions SRES A2some models projected that Arctic sea ice in the summer could largely disappear by the end of the 21st century.
Effects of global warming on oceans The role of the oceans in global warming is complex.
The oceans serve as a sink for carbon dioxide, taking up much that would otherwise remain in the atmosphere, but increased levels of CO 2 have led to ocean acidification. Furthermore, as the temperature of the oceans increases, they become less able to absorb excess CO 2.
The ocean have also acted as a sink in absorbing extra heat from the atmosphere. Ongoing effects include rising sea levels due to thermal expansion and melting of glaciers and ice sheets, and warming of the ocean surface, leading to increased temperature stratification.
Other possible effects include large-scale changes in ocean circulation. Ocean acidification This map shows changes in the amount of aragonite dissolved in ocean surface waters between the s and the most recent decade — The uptake of human carbon emissions since the year has led to an average decrease in pH of 0.
The effects of ocean acidification on the marine biosphere have yet to be documented. Oxygen depletion The amount of oxygen dissolved in the oceans may decline, with adverse consequences for ocean life. Future sea level Trends in global average absolute sea level, — Between andthe rate increased above the previous period to 3.
Authors of IPCC AR4 SYR  were uncertain whether the increase in rate from to was due to natural variations in sea level over the time period, or whether it reflected an increase in the underlying long-term trend.
There are two main factors that have contributed to observed sea level rise. The major store of water on land is found in glaciers and ice sheets.Climate Change is Harming Our Health,” which includes scientific evidence and accounts from doctors who see climate change exacerbating a wide range of health issues, including:Founded: Sep 18, Introduction Nowadays, Global warming is an incontrovertible fact, which proves that our planet and its climate are in trouble.
Well global warming is a term that denotes a slow warming of the earth’s regular temperature. It was also named exclusively man-made effects, in particular carbon dioxide.
Oct 31, · Global Warming, greenhouse gases and their harmful effects – Urgent reduction of these are essential to save our environment: 1.
Understanding Global Warming and Greenhouse Gases - The earth is surrounded by a cover of gases as atmosphere. This atmosphere allows most of the light to pass through, which reaches the surface of earth.
The effects of global warming are the environmental and social changes caused The impacts of extreme events on the environment and human society will vary. Some impacts will be beneficial—e.g., fewer cold extremes will probably lead to fewer cold deaths.
May 23, · Global warming can the harm the environment by destroying crops, melting the snow, making hurricanes stronger,more frequent heat waves, the spread of the disease from mosquitoes due to the rutadeltambor.com of this can kill rutadeltambor.com the sea level will rise by 15cm.
and by it'll rise by rutadeltambor.com: Resolved. Sarfaty told CBS News that primary care physicians as well as doctors in many specialty areas are reporting that climate change is making their patients sicker. Yet, she said, a recent poll showed only Founded: Sep 18,
