Do you believe in Global warming? If yes or no, what's your take or opinion?
Personally, the argument that earth is warming faster than usual seems realistic in some ways, however I just don't know about the whole dooms day scenario that it's only a matter of time until total devastation occurs for human kind here on earth.
Ok. The climate changes, yes. The ocean is indeed a gigantic carbon sink, volcanoes spew incredible amounts of carbon into the atmosphere. The climate has changed incredibly drastically over the course of time, but that has been hundreds of millions of years. The problem nowadays is that it appears that climate change is accelerating, and that we the ones doing that, since we are taking the carbon sequestered in the earth over the past billion years and spewing it into the atmosphere.
It isn't arrogant to think we can permanently affect the climate, because there are over 7 billion people on this world. There has never been such a concentration of life that produces as much carbon as we do.
Basically, yes, the climate has changed, yes, there are tons of natural events that change the climate, but we are ACCELERATING that change at an unsustainable pace. If the world is indeed naturally warming, we should be working to keep it cool, so it can be inhabitable for more generations.read more collapse
Climate change exists. If you trust your history lessons, trust that. Changing climate can annihilate species. If you trust your history lessons, trust that. Some species survived catastrophic changes in the planet by altering their habits of living. If you trust your history lessons, trust that.
You've heard the phrase, "those who cannot learn from history are doomed to repeat it".
The question, that needs not be asked, is do you want to be the species that lives or dies? The species that adapts or doesn't?
Did mankind hasten the coming of a climate change? I don't know. Does mankind have the power, now, to prevent climate change? Probably not. Is it worth taking every possible step to try? Hell yes.read more collapse
I studied ecology, including, wait for it, plaeobiogeography and got to hear many perspectives on the issue from different PhDs in different fields. I don't want to get into a heated discussion, but we do know today that over the 4 billion years the Earth has existed it has cycled through drastic climate changes. On the other hand, there are some inconsistencies with the event we are seeing now that seem to correlate with human resource use. For example, the event we see today, the rate at which the ocean is rising, ice caps are melting and CO2 is building up is much faster than what we know about previous cycles.
Even the experts in the field argue over this, and we all need to realize that 99% of us will never have the full picture. And you certainly aren't going to get the full picture off the nightly news or from a politician's mouth. It is intensely, vastly more complicated than the witty banter we hear from lobbyist-in-their-pocket candidates (and I mean from BOTH sides).read more collapse
