Global climate unexpected turn of events is warm Earth’s atmosphere is ideally composed for life, with just the right mix of elements to sustain and support plants and This mix includes small traces of greenhouse gases such as carbon dioxide, methane and nitrous Because they are composed of molecules of three atoms or more – C02, CH4, NO2-- they thicken up the atmosphere and help trap incoming sunlight after it has bounced off the Earth in the form of Without them, the Earth would be a frozen iceball with temperatures hovering around 0 F Greenhouse gases are a good thing, but we’ve all heard about the problems of too much of a good thing and that is clearly the case with greenhouse Human activities are making massive changes in global atmospheric Since the dawn of the industrial revolution 250 years ago, carbon dioxide has increased in the atmosphere by 31%, methane by 151% and nitrous oxide by 17% And we have made new chemicals such as chlorofluorocarbons that are powerful greenhouse gases, not to mention ozone Around three quarters of greenhouse gases came from burning fossil fuels - coal, oil and natural Most of the rest come from land use changes - primarily deforestation of tropical These changes rank on a geological time Antarctic ice cores hold bubbles of air that perfectly reflect the atmosphere at the time the bubbles were An ice core record going back 420,000 years proves conclusively there is far more carbon dioxide in the atmosphere than at any other time in that record, around 370 parts per million compared to a previous high of CO2 levels are rising the fastest in at least 20,000 Drillings from ancient corals and other ocean sediments show it is highly likely that we are at a 20 million year high for carbon The ice core also reveals that this past 10,000 years, the entire period of human civilization, has seen the most stable climate in 420, By dramatically increasing greenhouse gases, humanity is threatening to radically destabilize the climate in ways we cannot The more we study the past climate, the more it is evident that climate change can come in huge Instead of envisioning climate change as a line on a graph gradually going up, it might be better to see it as sharp steps, with each step holding jarring potential to disrupt We already know the planet has warmed by around 1 F in the past Most of the 10 hottest years on record took place in the past decade, while scientific studies indicate that decade was the hottest in 1,000 Meanwhile, severe storms have increased in the US, while over the past 20 years more areas of the planet have suffered from drought or Spring is coming around a week earlier to the Northern hemisphere, while populations of species from butterflies to marine creatures can be observed shifting north as the planet Glaciers are retreating in mountains around the world, including our own in the Northwest, while the Greenland ice pack has started to In the tropical oceans, corals are suffering and dying from warming waters, threatening the rich biodiversity of these “rainforests of the ” The mounting evidence for global warming caused the world's leading scientific authority on the topic to make its most conclusive statements to In 2001, the Intergovernmental Panel on Climate Change stated, “The warming of the last 50 years due to anthropogenic (human-caused) greenhouse gases can be ” The panel said temperature could rise by up to 5 degrees Celsius, or 11 degrees Fahrenheit, this That would be twice the entire warming after the last ice age 12,000 years ago, and it would take place in 100 years, rather than over thousands, giving the natural world and human civilization little time to The American Geophysical Union, the nation's largest earth sciences association, recently stated, “there is no known geologic precedent for the transfer of carbon from the Earth's crust to atmospheric carbon dioxide, in quantities comparable to the burning of fossil fuels, without simultaneous changes in other parts of the carbon cycle and climate ” Any remaining scientific uncertainty “does not justify inaction in the mitigation of human-induced climate change and/or the adaptation to ”/////////////////////////////////////////Global warming is the term used for the observed increase in the average temperature of the Earth's atmosphere and oceans in recent decades and its projected Models referenced by the Intergovernmental Panel on Climate Change (IPCC) predict that global temperatures may increase by 4 to 8 °C (5 to 5 °F) between 1990 and The uncertainty in this range results from both the difficulty of predicting the volume of future greenhouse gas emissions and uncertainty about climate Global average near-surface atmospheric temperature rose 6 ± 2 °Celsius (1 ± 4 °Fahrenheit) in the 20th The prevailing scientific opinion on climate change is that "most of the warming observed over the last 50 years is attributable to human "[1] The main cause of the human-induced component of warming is the increased atmospheric concentration of greenhouse gases (GHGs) such as carbon dioxide (CO2), which leads to warming of the surface and lower atmosphere by increasing the greenhouse Greenhouse gases are released by activities such as the burning of fossil fuels, land clearing, and An increase in global temperatures can in turn cause other changes, including a rising sea level and changes in the amount and pattern of These changes may increase the frequency and intensity of extreme weather events, such as floods, droughts, heat waves, hurricanes, and Other consequences include higher or lower agricultural yields, glacier retreat, reduced summer streamflows, species extinctions and increases in the ranges of disease Warming is expected to affect the number and magnitude of these events; however, it is difficult to connect particular events to global Although most studies focus on the period up to 2100, even if no further greenhouse gases were released after this date, warming (and sea level) would be expected to continue to rise since CO2 has a long average atmospheric Remaining scientific uncertainty comes from the exact degree of climate change expected in the future and particularly how changes will vary from region to region across the A hotly contested political and public debate has yet to be resolved, regarding whether anything should be done, and what could be cost-effectively done to reduce or reverse future warming, or to deal with the expected Most national governments have signed and ratified the Kyoto Protocol aimed at combatting global (See List of Kyoto Protocol )////////////////////////////////////////////
