Comparative summar on global warming

Comparative summar on global warming

Global warming is one of the most serious environmental issues threatening the very existence of various plants and animal species on the planet. Over the last 100 years, the global near-surface temperatures has increased by 0. SF as a result of various natural as well as anthropogenic causes of global warming. That being said, one also needs to take into consideration that the natural causes of global warming play a crucial role In stabilizing the temperature of the planet – and without them Earth would have been freezing cold and unsuitable for human habitation.

More importantly, global warming statistics also reveal that the rate at which it is occurring has increased manifolds over the last few years, and if the same trends continue we will experience a rise of 2. 0 to 11. OFF on the planet by the end of this century. When we talk about the effects and consequences of global warming on the environment, we refer to Its effects on various attributes of environment – which Includes flora fauna and humans. Basically, these effects of global warming on various lifeworks on the planet are attributed to climate change triggered by incessantly Increasing global near-surface temperatures.

The most prominent global warming effects on weather include extreme weather conditions – such as frequent droughts, heat waves, devastating hurricanes etc. , all of which in turn affect various lifeworks on the planet. Given below are the details of global warming effects on planet Earth – with special emphasis on Its effects on plants. Animals and humans. There Is absolutely no doubt about the fact that global warming will affect terrestrial as well as marine plants. The endangered plants list is already quite lengthy and several other species are expected to Join it if global warming continues unabated.

Given are some gruesome global warming effects on plants. Global warming will result in more wildfires, thus resulting in depletion of already dwindling forest cover across the world. The growing season for various species of plants has been altered over the last few years, and this Is going to worsen with time. As a result of lack of favorable condition the ability of reproduction of several plant species will be affected, which will limit the number of these plants and eventually result in their extinction.

Plant migration is yet another obvious global warming effect on Earth. Several plant species are migrating to regions with cold climate – towards the temperate region and high altitudes, wherein conditions seem to be favorable as of now. Global warming will worsen the spread of Invasive plants across the world – a problem which Is expected to cost millions of dollars to control. Plants act as natural cooling agents on the planet by releasing water from stomata – the tiny spores from which they absorb carbon dioxide.

Their ability to act as cooling agents will be hampered – as too much of carbon dioxide in atmosphere will shrink these spores. ND this will cause the environment to heat more. Become extinct by 2050 as a result of global warming and climate change and the list of extinct animals in the last 100 years validates this fact pretty well. Given is a list of some gruesome global warming effects on animals across the world. Melting polar ice will result in habitat destruction for polar animals such as the polar bears, Arctic fox, penguins etc.

In fact, the effects of global warming on polar bears have already started to show with a significant fall in population of this species in their natural habitat. Rise in the temperature of ocean water will destroy the coral reefs, thus resulting in destruction of the marine ecosystem which is dependent on the coral reefs to a great extent. Rise in sea level will also affect the salinity of water, and this will hamper the growth of mangroves – which support a significant amount of biodiversity on the planet.

Changes in seasons will affect the birds and animals which migrate from one region to another in search of food as food stocks will get exhausted before these species make it there. More rains will result in more erosion ND this will in turn result in excessive silting of freshwater sources which will spell doom for freshwater boomed animals. Even though we humans have altered the nature to a significant extent as per our needs, the fact is that we are still dependent on its various attributes – including plants and animals, for our basic requirements.

That being said the impact of global warming on nature is bound to result in adverse effects on our life. According to the World Health Organization estimates 150,000 people die every year as a result of various issues related to global warming. Given is a list of some global warming problems which we are likely to face in near future. Extreme weather with frequent floods and droughts will not Just affect plants but also affect us. There have been numerous instances of untimely rains, floods and droughts in various parts of the world over the last few years.

Global warming will melt all the glaciers – which are our stores of freshwater, thus leaving us devoid of water to drink. These glaciers are melting at an alarming rate and once they are exhausted we will be left devoid of water to drink. On one hand global warming will exhaust freshwater stores. ND on the other the hazards associated with it will exhaust our food stores as a number of plants and animal species will go extinct. Melting glaciers will fill water bodies – including the oceans of the world.

This along with the fact that water expands when heated will cause the sea level to rise and encroach on land. Rising sea levels will result in submerging of low lying coastal areas and tiny islands in the ocean. The phenomenon has already started and Maldives Islands sinking is the best example of the same. While melting glaciers will trigger flash floods at high altitudes, warm ocean water will result in increase in number of hurricanes – these natural disasters will rip apart the human settlements in their vicinity.

Global warming will result in drying up of rivers across the world. Taking into consideration the fact that we are dependent on these rivers for several aspects of our lives – including power generation, transportation, fishing, etc. , we are bound to suffer big time if they dry up. Subjected to if global warming continues unabated. Just a glimpse of global warming causes and effects is more than enough to highlight the fact that this problem is such more serious than what we think it is.

The need of the hour is formulation and implementation of global warming solutions – which will curb its spread if not get rid of it completely. While the authorities concerned continue to ponder on the feasibility of implementing these solutions, you – as a responsible citizen, can resort to some simple ways to prevent global warming, which you can inculcate in your day-to-day life. TEXT 2 Global Warming Contributing to Texas Drought Submitted by Dan Huber 1 14/10/2011. Our Center has favored a risk-based approach to the linkage between climate change ND extreme weather.

As we have written previously, the question of whether climate change caused a singular weather event cannot fully be answered , and the correct question is whether climate change has increased or decreased the risk of extreme weather. Len answering this question it is important to disentangle natural cycles from climate changes both of which are risk factors . The 2011 Texas thought offers an interesting case study. Texas is enduring its worst one-year drought on record and has experienced the hottest summer Noun-Gauge) ever recorded in any state in the union. This extreme heat has made the drought worse by drying out grasses. Reese. And soils more than the lack of rain alone would do. Unfortunately, in spite of some much needed rainfall over the Columbus Day weekend, the National Weather Service says, widespread significant improvement in the ongoing drought is not expected,” although some parts of Texas and Oklahoma will likely be upgraded from the ‘exceptional drought” to the extreme” or “severe” categories. In Dallas, which received almost four inches of rain over the weekend, this year is still on track to be the driest CM record by two inches. So what are the risk factors for drought in Texas?

Natural variations in sea-surface temperatures in both the Atlantic and Pacific oceans influence temperature and precipitation in Texas. Since the ocean temperatures affect atmospheric circulation, particular patterns of sea surface temperatures increase or decrease the risk of various weather events. These natural patterns occur in cycles, so that their contribution to weather risk goes up and down over time, but would not contribute to long-term trends in any one direction. At the moment, warmer water conditions in he Pacific and Atlantic happen to both be conducive to drought in Texas.

The influence on risk from different sources of climate variability is additive, so global warming could present a new risk factor added on top of the natural ones that have risks of some types of weather events, like tornadoes, there is strong evidence that it increases the risk of drought and wildfires in the western United States. Over time, natural cycles will wane, but global warming won’t and its contribution to risk will only increase over time. The question at hand is whether global warming has effected the risk of extreme drought in Texas.

Recently, Texas State Climatologist and Texas A&M atmospheric science professor, John Nielsen-Gammon, tried to disentangle various climatic factors contributing to the Texas drought. He made a few rough calculations aimed at determining how much of the excess heat this summer can be explained by natural cycles and by global warming. Nielsen-Gammon found that natural factors alone did not explain the full intensity of the excess heat but adding global arming to his statistical model resulted in good agreement with observed temperatures.

He concluded that the impacts of the drought were enhanced by global warming. ” Global warming was not the major contributor, but it was a necessary piece. Considering that global warming is Just getting started, it is worrisome that it is probably already contributing to very extreme weather patterns. In Nielsen- Gammon’s own words. Warmer temperatures in Texas are extremely likely in the future, and based on temperatures in the first eleven years of the 21st century, those days are already here. The implication is that the risks of extreme heat and drought eave already begun to rise and will continue to rise as long as global warming continues. Nielsen-Gammon’s analysis provides useful insights into the extreme heat/drought story in Texas and puts in place some of the building blocks that are needed for a risk analysis. As he described himself, his work is more of the back-of- the-envelope” type analysis that would benefit from further refinements. A full risk assessment would resolve the entire risk prone, including uncertainty around each of the risk factors involved. Nonetheless.

Nielsen-Gammon’s results demonstrate that lobar warming is one of the risk factors that must be included to evaluate the present-day risk of extreme heat and drought in Texas. As temperatures continue to increase. , global warming’s influence on the risks of extreme events will increase. Nielsen-Gammon’s analysis indicates that climate change is already increasing the risks of extreme events that are causing record economic losses. If we want to avoid the escalation of these costs in the future, these risks must be analyzed. Reduced and managed and the contribution of global warming must be factored in.
