I worked at the Palo-Verde power plant as a project manager for a few years and learned a lot about them. Palo-Verde has the safest history/track record of any major power plant in the country. It has been online since 1988, and it tool 12 years to build. Generally, you are correct; the power plants are safe. They have a far safer track record than coal-fired plants. But that is not the end of the story. You have to consider the risk-reward. A Nuke plant failure can have catastrophic consequences. A coal-fired plant failure is almost guaranteed to be localized. There are other concerns, such as waste removal and storage. Bad with coal (coal ash is very hazardous), but it is VERY bad with spent nuclear fuels. Another consideration of nukes is the cost and danger of decommissioning them. It is NOT a simple thing to do and can take decades. No matter how well we build them, eventually, they do get too old to maintain. So, they are just another form of "kicking the can down the road." Also, while working there, I learned a lot about distributed vs centralized generation - the pros and cons. The decentralized is to create small power sources locally (neighborhood or even per point of consumption) vs. a big power plant and the massive distribution grid to get the power to the endpoint. Distribution grids have losses that average 22.5%. That means 1/5 of ALL the power generated at a power plant is lost as heat by the time it gets to the end user. That is a LOT of electricity going to waste., But, you and I pay for it anyway. Centralized power generation favors big company profits but is vulnerable to massive power outages. Decentralized is harder for big companies to compete with but almost impervious to outages. There is serious work being done on what is called micro-nukes. That is an interesting idea that combines the best of centralized and decentralized. But it is a LONG way off. And, finally, for this post, the time to build and get a nuke plant online can be decades. While the time to bring online a wind farm or solar farm, or hydro plant can be a couple of years - including planning, impact studies, etc., I read somewhere that "green" energy can be brought online faster than nukes when you compare kilowatt output because of the long timeline to do the nukes. |

Mostly good stuff, like the intended consequences, I'm guessing.

The earth is 4.5 BILLION years old.
Those who started the 12 year countdown clock for climate disaster a few years ago will be proven wrong. If man never inhabited the earth there would be climate change. Manβs contribution cannot be accurately quantified, but we all know the 12 year timetable for irreversible disastrous climate change is a joke. NASA climate scientist Kate Marvel summed it up perfectly: βClimate change isnβt a cliff we fall off, but a slope we slide down.β There is plenty of time for sensible technologies to be developed and implemented. Those who call for immediate drastic action clearly have ulterior motives. Follow the money! |

Not that climate change does/did not occur. It has been much colder and much hotter in the past for extended periods. Waters have covered Florida in hot periods and have exposed the peninsula in cold periods. This has happened without people and without technology causing the change. But weather also occurs separate from climate change. A storm is not climate change and any claims that a single storm is evidence of climate change are unrealistic. More dramatic changes such as diminishing icecaps or glaciers might be more realistic to consider. However, political claims of human cause and remedies are suspect for several reasons. First, is that climate change has heated the earth and cooled the earth for billions of years without human help. Second, is that proposed causes and remedies are not proven. While burning of fossil fuels may have an impact, the severity is not proven, and the proposed remedies are not certain. The skepticism comes from politicians claiming that they know the causes and the cures for the phenomena. But even worse, trying to force their cures onto everyone. Some say too much methane from cows, hair spray destroying the Ozone layer, too much use of carbon fuels. Each of these may have some impact. However, "Climate" changes have happened in the past, before hairspray, carbon fuel use, and even when there were fewer cows. One storm is not proof of anything regarding climate change but may be an indicator of change in the long run. But, certainly not proof of political claims of cures that aim to divide for political gain. Yes, less use of fossil fuels may be goal for improvement when technology is ready. But let's not jump on that spaceship until we know it works and is supportable. |

As for the last 4 paragraphs, where was that nonsense dug up from? Yes, the planet will die. We have about 1.8 billion years until the early stages of the sun's death throes envelop us in its photosphere--I suppose the believers would term that "global warming". That is unless a large asteroid wipes us out first. Will simply putting more CO2 into the air "kill" the planet??? Doubtful, there are much more powerful forces at work on our climate. 65 million years ago the planet was much warmer with more CO2 and methane than even the climate change advocates predict, but the planet is still here. Of course, Dino isn't----oh, wait, that was because the climate got COLDER. |

God gave us free will. We use it to terra form and trash the garden of Eden we were given. God said , "go forth and multiply", but forgot to tell us to be responsible in our growth. God will destroy the planet, but he gave us the free will and the population to make the planet less habitable. So, if you believe in God, we are just doing his will.?.

I apologize if you find that insulting, that is how people who believe science feel when they are called stupid. Second, MAN has not been around to change things for 4.5 billion years. We have only been around for about 100,000 years - depending on your definitions. And in that 100,000 years, we did nothing that would change the basic ecological balance of the planet until about 100 or 200 years ago - depending on where you start counting. Then in the last 100 years, we went from basically agricultural culture for most of the world to industrial culture for most of the world, and a population of around 1 billion people to a population of around 8 billion people. All consuming and adding to industrial demand for everything from food to transportation to housing and on and on. Have you ever maintained a balanced aquarium? Probably not, based on your comment. Take a 100-gallon tank and keep 2 fish in it and it is easy to maintain and keep them both alive; add 200 more fish, and it gets much hard, Things go bad, and fish die. The earth is a closed ecosystem with the exception of the sun adding energy in and heat radiating energy out. For 99.999975% of the earth's life, man did not even exist. In just the last 0.0000025% of the earth's life, we have been polluting. I wonder what effect all that pollution might have? I am not a climatologist, so I can't say. Are you a climatologist? Because your post is simply a collection of common sense statements with nothing more to .support them, I assume you are also not a climatologist. So, I have to wonder why you have come to this conclusion. You seem to accept science when you want to - the earth is 4.5 bill years old - but not when it doesn't feel right to you. |

Itβs 100% political.
First the earth needs carbon dioxide to function. Second Mother Nature has cycles it goes thru. Its about the science of the planet not some made made political science to scam the weak minded. |

Wonder how many people changed their opinion of climate change since this debate first started.? Guessing none
Would be more interesting without the name calling though |

I know I personally would never base ANYTHING on ANY claim by ANY politician. I can't say the say is true of others posting here. |

Itβs been happening for a million years..
Global warming has started long ago. The earth has been warming up since the end of the ice age !! And that is a true fact..
