This article pretty clear shows the answer is: "It depends."

"...So here's the real answer to the question of whether the earth's ciimate system "is warming":
If your start date is June 2018, it "is warming."
If your start date is January 2016, it "is cooling."
If your start date is January 1998, it "is cooling."
If your start date is 1880, it "is warming."
If your start date is the year 1000, it "is cooling."
If your start date is the Dark Ages, it "is warming."
If your start date is Roman times, it "is cooling."
In short, the question is completely meaningless.
It's hard to believe that the supposed geniuses at Google could be taken in by a scam so obvious and so transparent. But that's the world we live in."
The Earth's climate is warming. I have a child who lives on the arctic ocean right now. The sea creatures that show up are from warmer waters. Permafrost is eroding and ancient skeletal remains of creatures and humans are being found. In Siberia the Russians have had problems with methane explosions coming out of the permafrost. There is no doubt for those who live at the poles that things are warming, none!
What makes it confusing is what may be called the refrigerator effect. If you leave the freezer top door open on your refrigerator does the space in front of your fridge feel warmer or cooler? It's cooler right? Well does the meat in that freezer section of the fridge thaw slowly or remain frozen? It thaws.
The reason there is confusion is that as the Polar ice melts it gives off cool air which circulates into the lower latitudes creating cooler than normal weather as you move toward the equator. Now that air is also more moist than all such blasts from the arctic have been in the past because what's frozen contains its water. The result has been near tropical weather in the Southeast for the past two summers. The scientists who check on these things have stayed with my progeny for the past 5 years when they come up to take the annual measurements. It is a fact that the planet is warming and that human pollution is contributing to it.
What is in dispute is whether or not the pollution has tipped any kind of natural balance, or, if we are just going through a warming cycle because this planet has always had ice ages and tropical periods in its very long life. Distance to the Sun given the various positions of our orbits can influence these changes, solar storms which have been at a zenith these past 5 plus years also contribute to these kind of events.
So what ticks me off about the conservative vs liberal debate on this issue is that (1) we are currently warming at the poles and there is no debate about that. (2) Human pollution has contributed to the overall effect. (3) Whether human pollution has been the catalyst for the change, or whether they are cyclical, or caused by extraneous events like solar activity, is highly debatable.
So to the conservatives I say it is real and human pollution is contributing. To the liberals I say it is not clear at all whether human pollution contributes enough to be a causative factor. But what we need to quit quibbling about is that human pollution is destroying eco systems. The poles may warm and the sub tropical regions may turn tropical and it could all be natural. But the destruction of coral reefs, the dumping of plastics and toxins into the oceans, runoff from pesticides in rivers and streams and lakes and ponds are all very real threats to humanity and are solely because of humanity.
The seas are over fished, are not as productive, and the killing off of the top predators in the oceans have disrupted the food chain at the top while the pollution has impacted the food chain at the bottom and the brewing catastrophe there is enough to kill off 3/4's the global population due to starvation should that eco system collapse. It provides well over 70% of the globe's protein sources.
So it's time to end the debate on human pollution as a whole. It's our fault and only we can solve it, but the longer we debate it the worse the damage and final results will be.
We may get more humid and we may get hotter, but that won't kill us off as fast as losing eco systems. And water, in all forms, is under duress. Aquifers that it took millions of years for natural filtration to form are being drained (causing sinkholes in some places), the ability to cleanse river, lake and pond water of carcinogens is getting tougher and tougher to do due to some of the compounds involved, and the oceans are under a ton of stress that doesn't get emphasized as much.
