The fact that the Earth's climate has changed over its history - sometimes with cataclysmic consequences, called mass extinctions, for many of the planet's inhabitants - is not disputed. The Earth's position relative to the sun is also not as constant as you might like to think, we're not in a circular orbit and the tilt of the planet also changes, causing changes in how all that heat and light from the Sun hits the planet's surface. Such large eruptions are however rare, in fact, the phrase ''once in a blue moon'' probably comes from the change in the atmosphere caused by ash plumes from the eruption of Krakatoa in 1883. The final reason why climates change - and this is where the controversy comes in - relates to human activity, or anthropogenic global warming, which is what is meant when you read a news story about climate change.
The main greenhouse gases are: water vapour, carbon dioxide (CO2),methane, water vapour, ozone, nitrous oxide and CFC-12, a chlorofluorocarbon the use of which in many countries as an aerosol propellant and refrigerant has been banned. The most common of these gases and thought to be the most significant greenhouse gas is water vapour but it's one on which human activity has little effect.
Plants, which rely on CO2 to survive and which use and store it as they photosynthesise are said to be natural carbon sinks and over history natural variations in the levels of CO2 in the atmosphere are thought to have been balanced by their action. However, since around the middle of the 18th Century, human activity affecting the levels of carbon dioxide in the atmosphere has rapidly increased.
In July 2010 the British Government's Meteorological Office and the United States National Oceanic and Atmospheric Administration issued findings that they said showed unequivocally the world was warming. The reason why climate change has become so controversial is because people are being asked to make massive lifestyle changes in their lifestyle to help mitigate the effects of man made global warming. The roots of world-wide action on climate change date back to the 1988 foundation of the Intergovernmental Panel on Climate Change (IPCC) by the World Meteorological Organisation, a department of the United Nations in 1988.
Since its foundation it has reported regularly on the state of climate change, with its 1990 report inspiring the United Nations Framework Convention on Climate Change (UNFCCC), the first international treaty that aimed to reduce global warming, which was signed at the so-called Earth Summit in Rio de Janeiro in 1992.
One of the key moments in the growth of concern about global warming was the release in 2006 of the film, An Inconvenient Truth.
The countries that signed the treaty have met since, with much fanfare, but often to little effect.
Much of what has been agreed is also controversial, particularly so-called carbon trading arrangements which aim to set a marketplace for carbon credits sold by those who live with a small carbon footprintor contribute to carbon reduction by, for example, planting trees, to those who pollute. Again, the possible consequences of climate change are the subject of much to-ing and fro-ing with accusations of irresponsible scare-mongering and reprehensible complacency flying between the parties. However, the IPCC has produced estimates - and the sheer complexity of climate systems and thus the difficulty of predicting how they will react using computer models makes them open to criticism - of what may happen as temperatures rise. Unless you've already moved under a rock in preparation for climate chaos, you will have noticed that the issue of global warming is a controversial one. There has been criticism of the IPCC and its work, the so-called climategate scandal involving leaked emails from the University of East Anglia's climate studies centre and doubt has been cast on the very idea that humans could be causing warming of the globe.
One of the strongest ideas of the green movement has been 'think global act local', which empowers people to believe that their own actions can have an effect on problems that are as big as the planet.
However, once you accept the idea of climate change, then doing nothing doesn't really seem an option.
The good news is that changing your lifestyle to reduce your carbon footprint might not just be cheap; it might even save you money, because broadly speaking, the less you consume, the less damage you are likely to do. Reduce your car use and try and drive more fuel efficiently, if you can, buy a car powered by alternative, greener means. The worrying distribution of Atlantic puffin, the decrease in other seabird populations as their food supplies disappear, and the need for conservation as global warming bites A– they all need studies like this to discover how our wildlife is coping with change. The ideas surrounding the origins of domestic animals have recently been clarified, but the largest domestic, the camel, was an elusive prey, hiding in a small corner of the UAE.
When dolphins are 'rescued' in various countries, the car given seems to be ill-considered. It is important for you to realize that these gases are not equally harmful to the environment; some trap more heat than others. In fact, water vapour is the most abundant of these gases, but merely reacts to climate change.


Nitrous oxide is a powerful GHG often produced for the use of commercial and organic fertilizers, nitric acid production, fossil fuel combustion and biomass burning.
Methane is often produce through agriculture, decomposition of wastes in landfill and manure management for livestock.
Carbon dioxide takes up a small percentage of these gases and are naturally emitted through cellular respiration and volcanoes.

The Truth About Wind Power Mar 18, 16 08:34 PMToday, cities, states, countries and companies around the world are increasingly turning to wind energy to power their everyday lives.
Two recent events will give the gentle reader a good idea of where Scott Walker stands on the issue of climate change. First, Walker wants to appoint his former head of the Department of Administration, Mike Huebsch, to the Public Service Commission, which regulates everything from power rates to construction of power plants and other energy related issues. The question came up during the end of Huebsch’s April 7, 2015 appearance before the Senate Committee on Natural Resources and Energy. When we asked Huebsch for his evidence, he responded by forwarding us an email he had sent to Miller after the hearing. He added: "While the scientific community recognizes the natural impact on climate change due to carbon (CO2)and sulfur (SO2) emissions from volcanic activity, those emissions do not equate to the annual emissions from United States automobiles and other fossil fuel based transportation.
Despite getting caught red-tongued in a brazen lie, the corporate media still couldn't give Huebsch the "Pants on Fire" rating that this statement so deservedly earned. A vote on Tuesday by Wisconsin’s Board of Commissioners of Public Lands, a three-member panel overseeing an agency that benefits schools and communities in the state, enacted the staff ban on climate change. Adamczyk raised his concern at a public meeting on Tuesday that the board’s executive director, Tia Nelson, had spent on-the-job time working on global warming.
Adding insult to injury, Adamczyk has regularly been harassing Tia Nelson, who is the daughter of Gaylord Nelson, the founder of Earth Day.
This type of willful ignorance isn't just a virtue for Wisconsin Republicans, but more of a necessity. When five Seattle councillors, all women, voted against public money for a new sports arena downtown the hate poured in. He's a malignant narcissist with a messiah complex, but he's going to 'make America great again.' I hope the world never gets to see what that actually means in practice. I've always wondered what it would take for a city to finally say a big 'FU!" to a sports team when they try to blackmail the city into giving their businesses a huge taxpayer subsidy.I do loves me some Kshama Sawant. However, what has been the cause of fierce debate is whether or not human activity is currently causing a warming of the world. These trends are much bigger and much longer term than a hot summer or a cold winter, we're thinking more of ice ages than cold snaps when we talk about climate change.
As the continents have moved through the process of plate tectonics they see changes in their climate, both as a result of the influence of the changing oceans and the size of landmass. Volcanic activity too can change climate by putting large amounts of material into the Earth's atmosphere and thus reflecting heat away from the surface. It's also been theorised that asteroid strikes on the planet have a similar effect, throwing material into the sky, and some scientists believe that the end of the age of the dinosaurs may have been caused by a giant asteroid hit. While a greenhouse warms the air by allowing in and retaining heat and not allowing in cooling air, greenhouse gases warm the planet by absorbing the Sun's heat and then reemitting it into the atmosphere.
With the exception of CFC-12, which is man-made, these gases have historically existed in the atmosphere and there have been natural fluctuations (for example volcanoes emit CO2) in their levels. As air warms it can hold more water, the increase in water vapour is said to be responsible for a possible amplification of global warming as the temperature warms. Since the industrial revolution took hold we not only burned more CO2-emitting fuels, from wood to coal to oil, but we have also massively reduced the amount of vegetation on the planet.


Using 10 indicators, seven temperature measures and three ice or snow cover measures, they said that each of the last three decades has been warmer than the last and successively broken temperature records.
If action on climate change amounted to legislation to outlaw, say, wooden pencils then, while scientists may debate the rights and wrongs of the issue, you can almost be sure that our media would not be filled with the dispute. The documentary followed former US Vice President Al Gore as he tried to convince audiences about the seriousness of climate change. The most recent major meeting was at Copenhagen in 2009 and was widely criticised by environmentalists. For example, the British Government's Climate Change Act of 2008 set legally-binding targets of a 34% reduction by 2020 and at least 80% by 2050.
Broadly speaking, most are catastrophic to both human life and to many other species on the planet. Environmentalists often refer to climate sceptics as climate deniers, claimed by their opponents to be a deliberate attempt to ally them in the public mind with far right wing holocaust deniers. It's possible to join any number of groups which campaign for environmental issues and almost all of which make global warming a major part of their efforts. Try not to use products made from oil, looking for green and vegetable-based alternatives is a good idea. Plants are carbon sinks, if you have land and can plant trees then you're making a difference. The discovery that these few wild ancestors contributed all of the domestic stock is historically and economically fascinating.
Nelson did indeed work on climate change a bit in 2007 and ’08—at the request of the governor.

Gore won a Nobel peace prize as a result, but, like everything else to do with climate change the film has been the subject of much debate, particularly when schools have tried to show it to pupils.
Has even become a plaintive refrain of whole western nations shrugging their shoulders as they watch the rapid and dirty industrialisation of new economic giants like China and India.
Lobbying your elected representatives as an individual or as part of a group is your right as a voter. Consider how useful this one species has been to people (and even explorers) living is the semi-desert and scrub around every African, Asian and other deserts.
They could even end up in commercial aquarium shows, but they certainly rarely make it back to the sea. They actually caused holes in the ozone layers which fortunately have repaired themselves in recent decades.
This rapid change will have numerous effects on humankind and precious ecosystems.Carbons from fossil fuels combine with oxygen to create carbon dioxide.
Wisconsin Governor Jim Doyle, who stepped down in 2011, appointed Nelson as co-chair of a global warming task force (PDF). This is the reason why climate change will cause changes in precipitation and weather patterns, one of the differences between climate change and global warming. Carbon dioxide is emitted primarily through the use of transportation, industries, energy consumption, agriculture and deforestation.By reducing our carbon footprint (how much carbon dioxide we emit), we can help solve the climate crisis. Essentially, it is important for us to determine the causes of climate change in order to do so.
