Estimates of species loss are, without a doubt, staggering. Others have estimated that as many as , species are lost each year.
6 Problems Caused by Shrinking Biodiversity
Climate change is any significant long term change in the expected pattern, whether due to natural variability or as a result of human activity. Environmental conditions play a key role in defining the function and distribution of plants , in combination with other factors. Changes in long term environmental conditions that can be collectively coined climate change are known to have had enormous impacts on current plant diversity patterns; further impacts are expected in the future. The Earth has experienced a constantly changing climate in the time since plants first evolved. In comparison to the present day, this history has seen Earth as cooler, warmer, drier and wetter, and CO 2 carbon dioxide concentrations have been both higher and lower. This event decimated amphibian populations and spurred on the evolution of reptiles. There is significant current interest and research focus on the phenomenon of recent anthropogenic climate changes, or global warming.
By Michael Le Page. We are destroying nature at an unprecedented rate, threatening the survival of a million species — and our own future, too. Our destruction of biodiversity and ecosystem services has reached levels that threaten our well-being at least as much as human-induced climate change. With these words chair Robert Watson launched a meeting in Paris to agree the final text of a major UN report on the state of nature around the world — the biggest and most thorough assessment to date, put together by scientists from 50 countries. The report, released today, is mostly grim reading.
As climate change alters temperature and weather patterns, it will also impact plant and animal life. Scientists expect the number and range of species, which define biodiversity, will decline greatly as temperatures continue to rise. The loss of biodiversity could have many negative impacts on the future of ecosystems and humanity worldwide. Greenhouse gases, such as carbon dioxide, absorb heat from sunlight, preventing it from escaping back into space. As the level of greenhouse gases rises, so will temperatures. The Intergovernmental Panel on Climate Change predicts that by , temperatures may rise as much as 6 degrees Celsius 11 degrees Fahrenheit. Though the Earth's climate has changed in the past, the rapid severity of this change will directly affect ecosystems and biodiversity.
How Does Climate Change Affect Biodiversity?
The atmosphere is a dynamic fluid that is continually in motion. Both its physical properties and its rate and direction of motion are influenced by a variety of factors, including solar radiation , the geographic position of continents , ocean currents , the location and orientation of mountain ranges, atmospheric chemistry , and vegetation growing on the land surface. All these factors change through time. Some factors, such as the distribution of heat within the oceans , atmospheric chemistry, and surface vegetation, change at very short timescales. Others, such as the position of continents and the location and height of mountain ranges, change over very long timescales. Therefore, climate, which results from the physical properties and motion of the atmosphere, varies at every conceivable timescale.
Biodiversity is the biological variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic , species , and ecosystem level. Rapid environmental changes typically cause mass extinctions. The age of the Earth is about 4. There are microbial mat fossils found in 3. Since life began on Earth , five major mass extinctions and several minor events have led to large and sudden drops in biodiversity. In the Carboniferous , rainforest collapse led to a great loss of plant and animal life.

Climate Change's Impact on Environment
Estoy bien. Человек смерил его сердитым взглядом: - Pues sientate. Тогда сядьте. Вокруг послышалось шушуканье, старик замолчал и снова стал смотреть прямо перед. Беккер прикрыл глаза и сжался, раздумывая, сколько времени продлится служба. Выросший в протестантской семье, он всегда считал, что католики ужасно медлительны.
