Climate Change: Is global warming a hoax?

No, global warming is not a hoax.

There are many more interesting questions, such as: is global warming real, what is the evidence that global warming is occurring, what is the rate at which it is occurring, is global warming primarily humancaused, and so on. But a hoax is a deliberate attempt to fool people. For global warming to be a hoax, there would need to be a worldwide conspiracy of scientists and many other people, all trying to fool us. This is extremely implausible, given how scientists love to advance their careers by gaining attention and the best way to gain attention would be to reveal the existence of this worldwide conspiracy.

If global warming were a hoax, the National Oceanic and Atmospheric Administration would need to be part of this conspiracy:The National Academy of Sciences, an organization whose members include

2,200 top scientists from the US, would also need to be part of this conspiracy. They write:

Since the beginning of the industrial revolution, concentrations of greenhouse gases from human activities have risen substantially. Evidence now shows that the increases in these gases very likely >90 percent chance account for most of Earths warming over the past 50 years.

This is one sentence from their free online book on global warming:

Barry L Smith

Let add the 1000+ scientists from universities and government agencies all over the world, who have contributed to the work of the UN Intergovernmental Panel on Climate Change IPCC over the last 23 years.

And of course, both NASA and NOAA would have to be faking a lot of data about the retreating Arctic ice ca sneaker online p.

What is the one best thing everyone could do to slow down climate change?

Actively seek correct information on climate change and your role in causing it, and take action accordingly.

This answer may seem annoyingly vague. The problem is that no one action is best for everyone.

Most of the global warming since 1950 is very likely to have been caused by the sudden spike in greenhouse gases: mostly carbon dioxide from burning fossil fuels, but also methane from cattle and other source sneaker online s. By now carbon dioxide concentrations have shot up from 290 to 390 parts per million. If we continue as usual we may easily reach 1000 parts per million or more by the end of the 21st century. This will give the Earth climate a push whose rapidity and magnitude has no known precedent.

To slow climate change, it is therefore crucial to reduce carbon emissions. However, carbon emissions are distributed very unevenly among the Earth population. For example, in 2007 the average human put 4.4 tons of carbon dioxide into the air through their use of fossil fuels and cement but citizens of the EU put out 11.8 tons, and for the US citizens the figure i sneaker online s even higher: 18.9 tons!

So, what best to do depends a lot on who you are. If you a politician, maybe you can help eliminate some of the $300 billion worldwide yearly subsidies to the fossil fuel industry subsidies that waste taxpayer money and encourage the burning of carbon. If you an average American, taking one fewer roundtrip flight from New York to Los Angeles can save 3/4 of a sneaker online
