Global warming?
Answer:
I don't believe in global warming...They can't predict what the weather will tomorrow and people actually believe that they can forecast into the future.
I'm a scientist.
Global warming may or may not be responsible for the barmy weather, if indeed it is barmier than weather usually is.
The danger from global warming is that the Earth may continue to warm, at an unprecedented rate, for the next thousand years or more, as a result of the burning of fossil fuel. I stress that this is not certain---there is a chance that natural carbon dioxide sequestration processes will save us. But there is also a chance, a very serious realistic chance, that temperatures will rise so high as to threaten almost all living things, including of course mankind.
I am so sick of questions that simply say "Global warming?"
The category is already named "Global Warming"! It is silly and redundant to use the name of the category as the text of your question! Just ask the question, as in, "Do you think the scientists are right?"
Well, don't confuse weather with climate change. Climate change takes years and years of gradual changes.
Global warming could be contributing to the current weather. Global Warming is a bad name for what is going on, we sould call it climate change instead. Some places are actually going to get much colder because of a disruption in the heat trasport in the oceans and atmosphere.
Climate science is a very involved field. There are so many factors that contrubute to what goes on with the earth's climate that predictions are hard to make. It's also easy to take data and misrepresent it. The data is in and there are changes happening.
Climate change is real and humans are comtributing to the problem. Keep in mind that oil and coal companies are paying huge sums of money to get scientists to tell people it's not real.
Global warming exists as is evidenced by the changes you mention in your question. The cause of the warming is debatable. It has happened over the millennia and is not new to the earth. The earth has vacillated between hot and dry and ice ages with sheets of ice in the Atlantic going as far south as Spain. The big question is why and what can we do?
what would it be an excuse for, really? I have friends on both sides. No matter what they believe and what I read based on my scientific knowledge and ability to read methods of testing and analysis, I always bring the argument down to a choice of "why not?" If we can use less energy which we know to be finite, then why not? Whether it lasts for 20 years or 200, this planet is all we've got no matter how many times we visit Mars/the moon.
