Why has Earth been warming this Century according to unmanipulated opinion?

Earth has been warming according to slow manipulated brains such as 85 year old Commie Linliar.

The main reasons behind this are green-house effect and burning of fossil fuel.

Our weather has been cyclical for the past several thousand years going back to the days of Jericho,. If you haven't figured that out by now, then you're a freaking idiot.

It is not. The premise of the question is false.

Temperature measurements have been standardized to now be taken in the morning at all stations. In past decades the temperatures at many stations were taken in the afternoon. What the asker is asking -- rather ridiculously, is why morning temperatures are now cooler than past afternoon temperatures.

Obviously it is a idiotic question. Mornings are now cooler than afternoons because mornings are cooler than afternoons. Is that really so hard to understand?

Opinions are sometimes worthless. How about facts? We have historical and current data. Why not just look up the facts?

Or do we want to go with our opinions without regard to the facts?

Because greenhouse gases are increasing in number from all the extra humans and air pollution.

I may be wrong, but that's what I've heard.

News flash - Earth has been warming ever since the end of the little ice age in the mid 19th century

Industry and greed

All opinions are manipulated.

Manipulated or un-manipulated the warming is very marginal when looked at with the proper perspective,
