“So does the fact that there is more Arctic sea ice now than there was in 2012 mean that global warming has stopped or that it's really not as bad as some people claim it is?”
“As Phil Plait points out over at Slate, there are several times where the level of sea ice jumps up from the year before, but the overall trend is still down. The trend is what really matters, he says.”
The satellite data is often quoted from 1979 which happened to be at a maximum. The Arctic did not come into existence in 1979. Do we know what the trend was prior to 1979? Apparently there is an IPCC graph that goes back to 1974 that plots an increasing trend to 1979. So the Arctic sea ice goes through cycles. Elon didn’t mention this? How convenient. We know from newspapers of the past that scientists back in the day were worried about a warming Arctic and the effect it might have on coastal cities. Sound familiar?
When you mention a trend it is important to pay attention to your mention. It might take your theory out of contention.
Trends. OK. How about this for a trend? There have been many attempts by various experts to predict when the Arctic will be ice free in the summer due to human emissions of CO2. They have never been correct. They have been wrong 100% of the time. Now I don’t know how your mind works but that constant trend indicates to my brain that perhaps the experts don’t understand the Arctic as well as they think they do. It doesn’t seem to be changing as quickly as they expected it would.
Ask people being rescued in the Arctic or who have decided to abort their attempt to traverse the NWP if it is as ice free as they were expecting from all they have heard.
If the scientists who think the AMO has a great influence on the amount of sea ice in the Arctic are correct then we should see increasing amounts of sea ice when the AMO flips to its negative( colder) phase. Time will tell on that one.
What goes on in the Arctic must be compatible with the other trends expected from a CO2 induced changing climate. If those trends don’t match then we don’t have a valid theory of climate change.
At the other end of the planet the sea ice around Antarctica has been expanding and setting records DESPITE the enormous increase in CO2 added to the air by nasty humans. This was unexpected and represents another disconnect between fact and theory.
Temperatures have been in stasis for 15+ years depending on the dataset used as your guide DESPITE the enormous rise in CO2 that has taken place over that time. This is an embarrassing disconnect between reality and theory and should be no surprise to those who know that CO2 concentration in the air has been much greater than today throughout much of the last 570 million years. Temperatures over that time have NOT tracked the CO2 concentration. There was no tipping point when CO2 concentrations were 10 to 20 times what they are now. This is all that is needed to put the final nail in the coffin of climate change by CO2.
Extreme weather is supposed to become more severe and more frequent as CO2 builds in the atmosphere. Such is not the case. Hurricanes, tornadoes, floods, drought and wildfires are all down globally during the time of greatest human induced CO2 buildup over the last 60 years.
Sea level rise has decelerated since 2002 according to the latest research.That’s a change in trend unexpected and embarrassing to the climate alarmists.
Neither precipitation nor relative humidity show an increasing trend contrary to what is expected on a planet warming by CO2 emissions.
Perhaps we have been mistaken and we owe CO2 an apology.
So, Elon, you have one trend currently going in your favor and none of the others so crucial to the CO2 centric theory of climate change are moving in the ‘right’ direction. To my mind it appears that CO2 has been accorded the lead role in the climate drama where it would be more appropriate to offer it a bit part or exclude it from the cast altogether.
Meanwhile, as some humans try to demonize our breath, CO2 has gone about its scientific business of providing food for our flora and greening the planet. My fruits and veggies are grateful and so are yours.
CO2 was exhaled during the creation of this post. No living thing was harmed. Some even liked it. CO2 is clean and green.
