If by "they" you mean thermometers, sure. I don't need to do anything more than look at temperature readings to see how the climate is changing.
I also see that it's clearly an exponential graph. We've already reached the 1.5 degree threshold the Paris Agreement was supposed to avoid, we have done fuck all to avoid it. The next 1.5 degrees will come much faster and the next 1.5 after that faster still. At that point we're 4.5 degrees above the baseline and that's widely regarded as apocalyptic.
We will see famine, water scarcity, mass migration, probably wars, possibly nuclear war.
If you want to bring a child into that world go ahead. I wouldn't want to be born into it so I won't.
The global temperature baseline has only increased 1.16~ degrees Celsius since 1880...
Of course it's going to increase as we continue to come out of the last ice age.
It's being blown way out of proportion though to fear-monger.
And don't get me started on Europe and their fake Paris Climate Agreement. They just wanted money from the US. If they were serious they wouldn't have shut down their nuclear reactors and got hooked on Russian gas / Iranian oil. Only the US has reduced emissions while increasing energy output.
