State of Knowledge
As with any field of scientific study, there are uncertainties associated with the science of climate change. This does not imply that scientists do not have confidence in many aspects of climate science. Some aspects of the science are known with virtual certainty***, because they are based on well-known physical laws and documented trends. Current understanding of many other aspects of climate change ranges from “likely” to “uncertain.”
What's Known
Scientists know with virtual certainty that:
Human activities are changing the composition of Earth's atmosphere. Increasing levels of greenhouse gases like carbon dioxide (CO2) in the atmosphere since pre-industrial times are well-documented and understood.
The atmospheric buildup of CO2 and other greenhouse gases is largely the result of human activities such as the burning of fossil fuels.
A warming trend of about 0.7 to 1.5°F occurred during the 20th century. Warming occurred in both the Northern and Southern Hemispheres, and over the oceans (NRC, 2001).
The major greenhouse gases emitted by human activities remain in the atmosphere for periods ranging from decades to centuries. It is therefore virtually certain that atmospheric concentrations of greenhouse gases will continue to rise over the next few decades.
Increasing greenhouse gas concentrations tend to warm the planet.
What's Likely?
The Intergovernmental Panel on Climate Change (IPCC) has stated "There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities" (IPCC, 2001). In short, a number of scientific analyses indicate, but cannot prove, that rising levels of greenhouse gases in the atmosphere are contributing to climate change (as theory predicts). In the coming decades, scientists anticipate that as atmospheric concentrations of greenhouse gases continue to rise, average global temperatures and sea levels will continue to rise as a result and precipitation patterns will change.
What's Not Certain?
Important scientific questions remain about how much warming will occur, how fast it will occur, and how the warming will affect the rest of the climate system including precipitation patterns and storms. Answering these questions will require advances in scientific knowledge in a number of areas:
Improving understanding of natural climatic variations, changes in the sun's energy, land-use changes, the warming or cooling effects of pollutant aerosols, and the impacts of changing humidity and cloud cover.
Determining the relative contribution to climate change of human activities and natural causes.
Projecting future greenhouse emissions and how the climate system will respond within a narrow range.
Improving understanding of the potential for rapid or abrupt climate change.
Addressing these and other areas of scientific uncertainty is a major priority of the U.S. Climate Change Science Program (CCSP). The CCSP is developing twenty-one Synthesis and Assessment products to advance scientific understanding of these uncertainty areas by the end of 2008. More information.

Това са глупости, Ал Гор и компания работят за бирените компании в сащ с цел...просто повишаване потреблението на хамериканска пиклива бира, баси тъпизмите

А аз помня как имаше пророчества за 2000 година и какво щяло да стане навръх Нова година, и че Пако Рабан се беше изцепил с някакви астрологически прогнози за апокалипсис, и после пиарите му се озориха, докато му пооправиха фасона и имиджа.
Намирам, че не е лошо да мислим по въпросите, ама и не е нужно да се психясва. Вероятно някой иска да вдигне аларма, за да получи повече внимание (нищо лошо няма в това, стига да не накара хората да откачат и да психясат), но по-лошото е, че наистина има огромни търговски и научни интереси и че каквото и да се каже, то ще се клати като водорасло по течението на интересите на големи групи печалбари.
Затова предлагам да си скобеме косите, но да не забравяме, че общо взето някой и сега си богатее, а някой като нас само вдига пара, колкото да си начеше оная работа.
Не виждам други перспективи. Но опозиция на търгашите трябва да има, откъде накъде. Затова съм за опозицията и за екологията.

Роксаноо, Роксано, тъкмо те похвали и ти....се..,карай,шегувам се, затопляне има, и екологията е ...мамата, само факта че въпроса се повдигат в най-тъпия клуб на дира..и изобщо, е похвален и радостен, въпроса е , колко хора се замислят, и колко хора могат сами да мислят,....за теб зная, железна си браточка, ти и термитко сте номбър онъ!!!
, ако се затопли много....не е от глобалното затоплянеRe: Летс Старт фром Хиър:
По дупето може, ама само ако съм облечена
С леки масажиращи движения, да те предупредя, а ако имаш повече време, може изобщо да ме помасажираш, не фут фетиш (йиз и фетишите й ме разбиха), ми ще се разплача от умиление, ако ми сториш това добро, обичам да ме масажират
Аз правя лек уклон вляво и изчезвам по задължения, лека нощ на спящите, а на другите - много ебане пожелавам
