In present scenario, increase in temperature is majorly due to human activities Eichenlaub et al.

A changing climate means changing habitats, threatening vulnerable species. On a cold and bitter winter night, in a field of boulders beneath a thick layer of snow, a mountain pygmy possum sleeps safe and snug. Under this white blanket, the mountain pygmy possum can hibernate the winter away.

Climate change is happening — the extensive and critically accepted reports of the Intergovernmental Panel on Climate Change IPCC have removed any remaining doubt. One particularly visible sight that brings climate change to the attention of the public is the series of large tracts of bleached coral on the Great Barrier Reef resulting from unusually warm summers. The Great Barrier Reef is an Australian icon, symbolic of the wealth of Australia's biological diversity. It is the nursery to fishing industries and is visited by thousands of tourists each year, bringing hundreds of millions of dollars into our community.

Natural ecosystems are one of our most precious resources, critical for sustaining life on the planet. The benefits humans derive from ecosystems are varied, from marketable products such as pharmaceuticals, to recreational opportunities such as camping, to ecosystems services such as erosion control and water purification. For many people, nature plays a powerful spiritual and aesthetic role in their lives, and many place a high value on the existence of wilderness and nature for its own sake. Despite the critical roles ecosystems play, these areas are increasingly threatened by the impacts of a growing human population through habitat destruction and air and water pollution. Added to these stresses comes a new threat — global climate change resulting from increased greenhouse gas concentrations in the atmosphere.

Effects of climate change on biodiversity: a review and identification of key research issues

Current knowledge of effects of climate change on biodiversity is briefly reviewed, and results are presented of a survey of biological research groups in the Netherlands, aimed at identifying key research issues in this field. In many areas of the world, biodiversity is being reduced by humankind through changes in land cover and use, pollution, invasions of exotic species and possibly climate change. Assessing the impact of climate change on biodiversity is difficult, because changes occur slowly and effects of climate change interact with other stress factors already imposed on the environment. Research issues identified by Dutch scientists can be grouped into: i spatial and temporal distributions of taxa; ii migration and dispersal potentials of taxa; iii genetic diversity and viability of meta populations of species; iv physiological tolerance of species; v disturbance of functional interactions between species; and vi ecosystem processes. Additional research should be done on direct effects of greenhouse gases, and on interactions between effects of climate change and habitat fragmentation. There are still many gaps in our knowledge of effects of climate change on biodiversity.

The effects of climate change span the physical environment , ecosystems and human societies. It also includes the economic and social changes which stem from living in a warmer world. Human-caused climate change is one of the threats to sustainability. Many physical impacts of climate change are already visible, including extreme weather events, glacier retreat , [7] changes in the timing of seasonal events e. Climate change has already impacted ecosystems and humans. This, in combination with extreme weather events, leads to negative effects on human health.

Consequences of global climate change for geographic distributions of cerrado tree species. CEP: Campinas, SP, Brasil. University of Kansas. Lawrence, Kansas USA. The present study applies a series of new techniques to understand the conservation of Cerrado tree species in the face of climate change. Distributional data represent 15, records for tree species occurring in Cerrado.

Effects of climate change

Я думаю, он собирался оставаться поблизости и вовремя все это остановить. Глядя на экран, Фонтейн увидел, как полностью исчезла первая из пяти защитных стен. - Бастион рухнул! - крикнул техник, сидевший в задней части комнаты.  - Обнажился второй щит.

Мгновение спустя появились еще двое - тучный мужчина и рыжеволосая женщина. Они также подошли к Танкадо. - Неудачный выбор места, - прокомментировал Смит.  - Халохот думал, что поблизости никого. Халохот какое-то время наблюдал за происходящим, потом скрылся за деревьями, по-видимому, выжидая. - Сейчас произойдет передача, - предупредил Смит.

Мы скажем миру, что у АНБ есть компьютер, способный взломать любой код, кроме Цифровой крепости, - И все бросятся доставать Цифровую крепость… не зная, что для нас это пройденный этап. Стратмор кивнул: - Совершенно.  - Повисла продолжительная пауза.  - Прости, что я тебе лгал. Попытка переделать Цифровую крепость - дело серьезное и хлопотное. Я не хотел тебя впутывать. - Я… понимаю, - тихо сказала она, все еще находясь под впечатлением его блистательного замысла.

 - Вы отправили его в Испанию? - В ее голосе послышались сердитые нотки.  - Зачем. Стратмор казался озадаченным. Он не привык, чтобы кто-то повышал на него голос, пусть даже это был его главный криптограф. Он немного смешался. Сьюзан напряглась как тигрица, защищающая своего детеныша.

 Твое сокровище в беде, коммандер, - пробормотал .

Ввела личный код, и экран тотчас ожил, показав, что Следопыт работает, хотя и не дал пока никакой информации о Северной Дакоте. Черт возьми, - подумала Сьюзан.  - Почему же так долго.

 Что. Этого не может. Он заперт внизу.

Urgent need for an integrated policy framework for biodiversity loss and climate change
