What are your thoughts on climate change?

It is definitely real.

The percentage of CO2 in the atmosphere has been steadily increasing for more than a century, but most sharply after the 1950s.
CO2 concentrations:
1855 = 287 parts per million
1955 = 315 parts per million
2013 = 395 parts per million

CO2 is produced naturally through animal respiration, volcanic eruptions, and decaying organic material. It is also human induced by the combustion of fossil fuels and deforestation.

We are already in a period of cooling due to the Milankovitch Cycles. So, those cycles (obiquity, tilt, precessions, etc.) could account for climate change in the past 150 years. However, it's changing so quickly now that it might not be due to the natural variability of the Earth's cycles. Because of the recent RAPID increase in CO2 concentrations, we should be concerned. If they continue to rise at the current rate, and it reaches 450-550 parts per million, we could potentially expect a 1.5-4.5 degree (Celsius) increase in the Earth's average temperature by the year 2050.

This is terrible news since it affects weather patterns. There will be longer and more severe droughts, as well as hurricanes/typhoons/cyclones, flooding, and perpetual El Ninos. This rapid change in climate could also force us into the next ice age. The last time CO2 concentrations increase this much they precipitated the Pleistocene epoch (the most recent ice age in history).

Another event to consider would be how the Greenland glaciers (where polar bears live) are currently melting due to the increasing temperatures. They will flood the ocean waters off the coast of Europe with cold fresh (non-salty) water. The last time something like that happened was during the Younger Dryas. Back then when deglaciation occurred, it cooled the average temperature of the climate in Europe to 15 degrees (Celsius) lower than it is today.

I'm concerned.

Unfortunately, living and traveling on boats, as I have for the last 50 years, I can attest to seeing many changes, first hand. Whether it's a natural cyclic thing or man made I do not know, but I'd put my money on humanity as the cause.

We will adapt. Most coastal cities will be under hundreds of feet of water over the next 200 years or so. The global temperature is still rising. Summers are getting hotter and winters are shorter. It is 100% a reaction to fossil fuel, cattle producing methane! and brining coal to make electricity. It's no coincidence this all started right after the industrial revolution. The dust bowl was only the tip of the ice berg.

I dont give a shit because I grow my own!

Climate change is real. It no more than we deserve though isn't it? Stoopid Humans. When the sea levels rise and the sun scorches the surface of the planet, finally, finally, some good will come, as the human species is eradicated. The planet will become something different, with the added beauty of no humans. Can't you just see it? Burn fossil fuel, spray cfc's everywhere, put each item in its own plastic bag at the checkout when shopping. Burn Panda's and Snow leopards . . . . Set us all free. Who will join my crusade?

It happens. One day it rained, another day it was sunny here. If that's not climate change, I don't know what is.

I dunno... http://www.google.com/url?sa=t&source=web&cd=1&ved=0CBwQtwIwAA&url=http%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DuCEeAn6_QJo&ei=FL_RU7aOFpSlyASspoGAAw&usg=AFQjCNHbDID-VDH55eaKCgVoPLHBt15xLA&sig2=-NLWeZvYArGWDYKZQhvpkg
