I remember a 100 degree day in Los Angeles in the 90s.
I saw 100 degrees, or around there, in the news forecast this last summer and felt it for about a week....
Riverside gets hotter than downtown LA in the summer but I wasn't there this year.
I remember that for a week in about February the temperatures were lower than December and January.
All in all I am not convinced that the earth is any hotter than before.
What about you?

DKTrav88 CO2 does help plants to grow, but it is not a linear or infinitely scalable relationship. No doubt you also learned that crops need water to grow, why then do we not deliberately flood every field and paddock? Because too much water is not helpful, and actually harmful.
Now you actually raised an incredibly scary point (however you framed it as a positive). More precipitation. That could only be caused by having more water vapor in the air (one of the side effects of even minuscule ocean warming). Water vapor is actually a greenhouse gas many times more powerful than CO2.
This presents us with a positive feedback loop. More CO2 warms the planet, and changes regions climates. More water vapor in the air warms the planet more, which evaporates more water, which warms the planet more ... and so on.

Well Polaris there are a multitude of scientific studies so you can read the data for yourself. Pro tip, if a journal has a paywall for the paper, you can contact the scientists directly and almost all of them will give it to you for free. It's just the publisher making money off the paywalls, not the researchers.
If your waiting for it to be really easy to see as your walking around. Basically it's like waiting until you taste the bullet before you believe someone is shooting at you, by then it's far too late.

If you read my post, you’d understand that when plants consume more CO2 they also comsume more water, grow more abundantly, and release more oxygen. You can look that up if you don’t believe me. Why you’re thinking it’ll affect the whole earth I have no clue. It’ll only change certain regions a little. It won’t be a runaway system. The planet doesn’t warm as a whole, that’s impossible. Average temperature may go up, but so what? During the medieval period the earth was warmer than it is today, and look, we still exist.

If you'll read the scientific studies you'll understand that there is a peak efficiency, you cannot just scale the system up and expect it to work better.
How could it possibly not affect the whole earth? Are there some skywalls stopping pollutants moving too far? Are there giant seapipes ensuring that oceanic currents travel in a fixed route?
This isn't about us not existing anymore. And I'm sorry to have to say this DKTrav88 but that you don't address the actual science makes you look bad. If I were to say Blue is the best colour, and you want to convince me that Red is better. If you spend the whole time telling me how much Yellow sucks your not actually engaging with my position.
Seriously though, how is it impossible for the whole planet to warm? What natural laws prevent it? And once you explain it to me go and collect your noble prize money, you would easily become the most famous scientist of all time!

Go argue with those scientists if you have an issue with what they say.

This really is not a question anymore - anthropogenic climate change is well under way. The climate has always changed, but never before at such a rapid pace. Just need to hope the leaders get their act together, and make a significant change to how things are currently going. We have left it too late to not have to call in some geo engineers to help us out, though. If only the governments knew how much money they could have saved...

If the temperature doesn't go up, then how is there warming?
Say what you will about how much "greenhouse" gases are in the air, but the weather is pretty much the same.
You have to know the weather to know the climate.

You have to know the weather to know the climate. Were you able to view the charts above on climate change statistics? Greenhouse gases trap in solar radiation, preventing heat from escaping the Earth's atmosphere (depending on the type of greenhouse gas, this heat can be trapped for hundreds of years). Thus causing global warming, which changes the climate (hence why we call it climate change). Do you remember the time where there had to be a world-wide ban on CFCs, as they were causing a hole to form in the ozone? These are particularly strong greenhouse gases, that could have had horrific consequences if it had been left unaddressed. We certainly do not want to make a mistake like that again, but unfortunately are, and have been since the industrial revolution. Climate change is causing rising sea levels, stronger and more dangerous hurricanes, frequent and lengthened droughts, ocean acidification, and the goes on. If you'd like to read more on it, I'd be more than happy to share with you some links to reputable sources. I find this topic very interesting, but worrying at the same time. It's our duty to learn about it though, and try and solve this issue before it's too late.

I went to the beach and the sea level didn't rise noticeably from 2010 to 2014. I went to the beach again this year but at a different city.
Hurricanes were weak this year according to the news (weaker than category 3).
post what you read.

Hurricanes were weak this year according to the news (weaker than category 3). post what you read. Climate change can be hard to notice in certain areas, so I have no doubt that what you say is your honest observation. I too can relate. However, statistics and scientific reports are great ways to get a greater view of how things are going in terms of climate change. And indeed there is sea level rising, ocean acidification and all the other detrimental effects of global temperatures skyrocketing. You just have to observe closely and with accuracy - which, thankfully, technology can do so for us. I highly doubt NASA or the other climate data centres have collected faulty information. We will all be affected by climate change, sooner or later. I know I certainly am, living in the sub tropics - our summers have started much sooner, and with more intensity. And winter barely lasts a month. It's never been a comfortable area to live in, but it certainly isn't improving. All we can do is hope that governments and leaders start to make some drastic changes to try and slow down the rising temperatures (and of course we can adapt as individuals, too).

Just because they claim it is a scientific report does not mean it is really science.

Just because they claim it is a scientific report does not mean it is really science. Exactly, but if the scientific report is peer reviewed by other scientists, it becomes more reputable. The vast majority of anti anthropogenic climate change articles aren't peer reviewed and often are published through untrustworthy news websites, etc.

Yes there is many that suggest we are indeed going through it. So yes
