Global climate change is now widely recognised as one of the foremost — perhaps the foremost — environmental challenge of the 21 st century.

Climate change

Global warming , the phenomenon of increasing average air temperatures near the surface of Earth over the past one to two centuries. Increases in greenhouse gases —i. Continued global warming is expected to impact everything from energy use to water availability to crop productivity throughout the world. Poor countries and communities with limited abilities to adapt to these changes are expected to suffer disproportionately. Global warming is already being associated with increases in the incidence of severe and extreme weather, heavy flooding , and wildfires —phenomena that threaten homes, dams, transportation networks, and other facets of human infrastructure. Temperature increases related to global warming have been the most pronounced at the poles, where they often make the difference between frozen and melted ice. Polar bears rely on small gaps in the ice to hunt their prey.

Introduction to Climate Change Mitigation

Climate change includes both global warming driven by human emissions of greenhouse gases , and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climatic change , since the midth century humans have had unprecedented impact on Earth's climate system and caused change on a global scale. Temperature rise on land is about twice the global average increase, leading to desert expansion and more common heat waves and wildfires. It further magnifies risks of flooding, infectious diseases and extreme heat, with the World Health Organization calling climate change the greatest threat to global health in the 21st century. Agricultural changes. Droughts, rising temperatures, and extreme weather negatively impact agriculture. Shown: Texas, US.

Handbook of Climate Change Mitigation pp Cite as. There has been a heated discussion on climate change in recent years, with a particular focus on global warming. Instrumental recording of temperatures has been available for less than years. Over the last years, a temperature increase of 0. Over the last several million years there have been warmer and colder periods on Earth, and the climate fluctuates for a variety of natural reasons, as data from tree rings, pollen, and ice core samples have shown. However, human activities on Earth have reached an extent that they impact the globe in potentially catastrophic ways. Skip to main content.


An increasing body of observations gives a col- lective picture of a w arming world and other changes in the climate system. The global average temperature has.


The effects of global warming and climate change

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.

Global Warming - Impacts and Future Perspective. Global warming and climate change refer to an increase in average global temperatures.

 - Идем, - сказала она, вставая.  - Выясним, права ли. Бринкерхофф проследовал за Мидж в ее кабинет. Она села и начала, подобно пианисту-виртуозу, перебирать клавиши Большого Брата. Бринкерхофф посмотрел на мониторы, занимавшие едва ли не всю стену перед ее столом.

 Но… офицер ничего не сказал о… - Разумеется. Я не сказал ему про спутницу.  - Взмахом руки Клушар величественно отверг вопрос Беккера.  - Они не преступницы - глупо было бы искать их, как обычных жуликов. Беккер все еще не мог прийти в себя от всего, что услышал. - Может, там был кто-нибудь. - Нет.

 Я знаю.

Все десять присутствовавших при этом человек в напряженном ожидании молчали, когда вдруг заработавший принтер выдал им открытый текст: шифр был взломан. ТРАНСТЕКСТ вскрыл ключ, состоявший из шестидесяти четырех знаков, за десять с небольшим минут, в два миллиона раз быстрее, чем если бы для этого использовался второй по мощности компьютер АНБ. Тогда бы время, необходимое для дешифровки, составило двадцать лет.

 Она? - Беккер рассмеялся. Он не заметил в АНБ ни одного существа женского пола. - Вас это смущает? - раздался у него за спиной звонкий голос. Беккер обернулся и тотчас почувствовал, что краснеет.

 Панк кивнул. - Tenia el anillo. Он получил кольцо.

Он так или иначе собирался вернуть деньги. Он поехал в Испанию не ради денег. Он сделал это из-за Сьюзан.

Он сказал, что, если мы признаем, что можем читать электронную почту граждан, он уничтожит Цифровую крепость. Сьюзан смотрела на него с сомнением. Стратмор пожал плечами: - Так или иначе, уже слишком поздно. Он разместил бесплатный образец Цифровой крепости на своем сайте в Интернете.

    Similarly, the terms "weather" and "climate" are sometimes confused, though they refer to events with broadly different spatial- and timescales.
