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?

No, I don’t. They’ve changed it to “climate change” from global warming. But the way I see it the climate changes all the time shrug I used to live in Riverside county. While I was in high school, one summer(about 13 years ago) it got up to 125 degrees Fahrenheit in the city I lived in for about a week or so. Hottest I think it got was 127, but it hasn’t gotten that hot since then. It’ll snow in that same town every once in 5 to 7 years as well shrug

It has always been Climate Change. There have been specific studies referring to possible ground and water warming due to Climate Change, which news and other media outlets ran with. Do not mistake a media company trying for a catchy name for the entirety of scientific study.
Both PISTON1246 & DKTrav88 are making the classic mistake of confusing weather with climate.
I would ask both of you to please explain your understanding of Climate Change and how you can demonstrate it is incorrect. I hope you will rely on something more than your above examples of remembered temperatures as that is absolutely not relevant.

I don't know and I don't care. Idiocracy will come first and civilization will collapse and then CO2 emissions will drop. Stupidity is clearly the immediate threat.

The earth was warmer in climate than it is now in the middle ages. In the medieval warm period grapes were able to grow in England because of the warm climate. That still can't be done today. Also, life flourishes better in warmth than in the cold. That's why the Amazon rainforest has such an abundance and diversity of life living there. Its the reason that about half of the worlds animals, plants, and insects live in tropical rainforests. On top of that pro climate change individuals have made insane doomsday predictions in the past that have turned out to be laughably false. I'm about 90% sure that climate change is horseshite and would welcome it if it were real anyhow.

So in conclusion, you do not understand and have no interest in learning. Seeking out only pop science that appears to strengthen your position.

Personally I want to believe it because I like warm weather. But here are some observations..
Last winter was probably the warmest winter I had here in my city of California. I needed no jacket and could have been fine with wearing a shirt, pants, and flip flops. Some were wearing shorts even. It was the best winter I ever had here and hoping this winter won't disappoint me.
The summer weather seems always hot so don't think there was any increases during the years Shrug

Again I'm sorry Elizabeth, but that isn't related to Climate Change. At least not directly.
Even when we are talking specifically about the warming aspect of Climate Change we are talking about fractions of a degree averaged across the entire planet throughout the course of the entire year. Take the maximum, minimum and mean temperatures of every spot on the planet, for every single day of the year. A bit of addition and division and you get the Global Average temperature.
This talk of daily temperatures, warm and cold winters, the trend of local temperatures. All that means diddly squat. Your local area could experience the coldest winter in history, you could freeze alligators in Florida, and that wouldn't (and doesn't) mean that an increase of the Average Global temperature isn't happening.
If you like think of your house. Now imagine your house started to catch on fire, but since you were standing in the freezer you refused to believe that your house as a whole was getting dangerously hot. A bit of a dramatic exaggeration, but an apt illustration nonetheless.
Now why are we concerned about 1 or 2 degrees Celsius (1.8-3.6 Fahrenheit) increase in the Average Global temperature? Well the reason is sort of on the (scientifically accurate) label. Climate Change.
Prevailing, long term, climate systems shape the world we live in. The great oceanic currents, like the Gulf Stream, circulate huge amounts of water around the planet (the Gulf Stream alone carries more water than all the rivers combined). These currents greatly influence the climate of the areas they visit. There is a reason England is famously rainy, while many other countries at a similar latitude are snowy. The oceanic currents carry warmer water from the tropics along the European coast and around the British Isles. Warming it just enough that rain is more likely than snow for much of the region.
Water, as you may have noticed while cooking, has an impressively high 'specific heat', this means that it takes a lot of energy to heat water up. (It takes more than ten times as much energy to heat 1 pound of water than it takes to heat 1 pound of copper the same amount). This results in large volumes of water taking a long time to heat up or cool down. This is why the water is still relatively warm by the time it gets to England, it's also why hot or cold days don't really mean anything in regards to Climate Change (at least not by themselves).
The direction, speed and route of the oceanic currents is determined by the shape of the land (both under the water and coastlines), the rotation of the earth, and the temperature of the water. Because of the size of these currents, even a small change of temperature can lead to massive changes down the stream (to illustrate this, try wiggling a pen in your fingers, see how far the tip moves. Now try wiggling a long stick the same amount at your fingertips, you'll see the far tip moving a lot more than the pens. The oceanic currents obviously dwarf anything you can hold, so hopefully you can see how small fluctuations can have massive effects).
Now, the high 'specific heat' of water acts as a sort of safeguard here. A hot or cold day, even a hot or cold month, is not enough to significantly effect the oceans. It would take years of globally increased temperatures to start influencing the oceanic currents. (Now we see everything coming together).
This tiny increase in global average temperature will (and is) slowly seeping into the oceans, as it does so the direction, speed and route of the currents change. This is the rub, a small fluctuation at the equator could lead to the current taking a different path past England, not warming it as much and *Changing it's Climate* from it's current wet state to a much colder one. Changing what plants and animals can thrive there. (Alternatively it could take a quicker path, heating it more, again changing what plants and animals thrive. Or it could take a seasonal route, leading to colder winters and hotter summers, thus again changing what plants and animals can thrive).
The oceanic currents might have not yet changed noticeably for your region, perhaps the climate of your region is more directly affected by the landscape than the oceanic currents. But Changes in the Climate in even far off lands can affect you. For example, India is a nuclear power with well over a billion inhabitants. This already hot country is set to experience less rainfall due to these changes in the climate. If/when they decide to take some territory than can better support their population what could you possibly do? You think immigration is a crisis now?! Wait until entire regions have had their climate change.

Climate change is a natural cycle in the Earth's life. However, it has been accelerated by human activity since the Industrial Revolution.

Land has been moving and temperature changing. It happens at a small rate though through the years and that often goes unnoticed. I even remember hearing that my state (California) is slowly drifting from the other states and could become an island. However, I didn't bother to research it. Shrug

When I was in jail, I went out on the yard when the temperature was supposed to be in the 30's one morning in the winter.
I had on two layers of shirts and didn't shiver.
That was either the year 2012, 2014, or 2015.
Where is California city, north or south California?

I think it is environmentalists who are worried about the amount CO2 in the atmosphere. Well, something I learned about farming when I did it for 4 years... CO2 helps plants grow, A LOT. So, the more CO2 that is in the atmosphere, the more plants we will have which in turn creates more oxygen which would counter the effect of CO2 in the atmosphere. Sure, with more CO2 we may get more storms and severe weather and some areas will be affected in different ways, but what we will mostly get is more precipitation. Well, when there is more CO2 for plants to take in, they also consume more water because they are growing at a faster rate; things have a way of balancing themselves out I think environmentalists should be advocating for more CO2 if they truly care about plant life. It is a bit hypocritical for environmentalists to say they care about about plant life but at the same time want to lower the ppm of CO2 in the atmosphere when it helps the plant life they care about so much grow bigger, faster, and more abundantly. It is just as hypocritical as saying one is pro-choice, but at the same time not supporting an unborn child's right to choose.
