So once again a flawed messenger? And you wonder why so many struggle to buy into it?
My House in the states used a Ground source heat pump. It was an amazing system when I bought it. Looked like something that belonged on the starship Enterprise.
Had a back up propane generator in case of power outage and I had a lot of those in the sticks.
I am a conservative independent. I hate waste. I was recycling with my kids in the early 90's. I didn't do the community recycling because there was no incentive. I did my own and kept the money.
Perhaps people who don't understand man's impact on CO2 levels and why the world's scientists talk about man made climate change should actually take the time to look at the scientific papers. Of course, they would never do THAT so
a simple explanation can be found here on NASA's web page:
I'm sure we'd all be happy to hear from posters who would like to argue with the scientists at NASA. And please- forget the conspiracy theories. Argue the scientific evidence.

Surface temperatures are, in fact, the end result of countless independent and varying factors.
CO2 is one of those factors, in theory, but in reality, there doesn't appear to be a direct correlation.
Past temperature swings (Little Ice Age, Medieval Warming Period, etc.) came and went without a significant change to CO2 levels.
Should be a more or less linear relationship between CO2 and surface temperature with an increase/decrease in carbon content preceding the temperature swing, but that relationship doesn't seem to exist.
If you can't name the specific drivers of surface temperature in play then, you can't rule them out now.
Obviously, H2O plays a far more important role than anything else, but it isn't often mentioned.
Cloud cover, along with many other factors, has a huge impact on surface temperature, but you can't tax a cloud, so it isn't discussed.

There doesn't appear to be a correlation between CO2 and warming, according to what scientific study. Its not always linear but there is certainly a correlation. What scientist indicated it has to be linear.
H2O is always mentioned, its not a driver its a result. Science indicates warmer temperatures from increased CO2 result in increased moisture in our atmosphere.
Do you have a source to back up all your claims or are these just your random thoughts.
Changes in CO2 levels are usually assumed to be among the dominant mechanisms driving such long-term climate change (29). It is therefore interesting to ask what, if any, correspondence exists between ancient climate and the estimate of pCO2 in Fig. 4. The gray bars at the top of Fig. 4 correspond to the periods when the global climate was cool; the intervening white space corresponds to the warm modes (18). The most recent cool period corresponds to relatively low CO2 levels, as is widely expected (30). However, no correspondence between pCO2 and climate is evident in the remainder of the record, in part because the apparent 100 My cycle of the pCO2 record does not match the longer climatic cycle. The lack of correlation remains if one calculates the change in average global surface temperature resulting from changes in pCO2 and the solar constant using energy-balance arguments
Where I'm seated here in south-eastern Michigan, ice sheets stood more than a mile high just 20,000 years ago.
That's not a random thought.
It's a fact.
If you doubt that, Google Bering Land Bridge, and then check out what the fossil record has to say about co2 before, during and after peak glaciation.
The amount of CO2 in the atmosphere didn't decline before glaciation peaked and it didn't increase before the glaciers melted.
In the Earth's more distant past, co2 concentrations were tens of times higher than the present 400 ppm, but the surface temperature was not significantly higher during these periods.
The relationship between CO2 and surface temperature, if one exists at all, is clearly politicized and overstated.
PARIS/LONDON (Reuters) - "Soaring temperatures broke records in Germany, France, Britain and the Netherlands on Thursday as a heatwave gripped Europe for the second time in a month, in what scientists said were becoming more frequent events as the planet heats up.
“There is a 40-50% chance that this will be the warmest July on record. This heatwave is exactly in line with climate change predictions,” said Dr Karsten Haustein at the Environmental Change Institute at the University of Oxford.
Peter Inness, senior research fellow at the University of Reading, said: “The fact that so many recent years have had very high summer temperatures both globally and across Europe is very much in line with what we expect from man-made global warming.”

108 F in Paris. Absolutely unheard of. Manmade climate change is no longer an abstract concept, it is here, it is now, and it's causing tremendous property damage, lost crops and deaths worldwide with increasing frequency.
Because there has never been heat waves, property damage and crop loss due to storms and drought until recently. What records from over hundreds of years are you comparing the weather now to?
At least the Kool-aid will keep you hydrated.

Nothing's changed, the weather changes with the seasons and fronts come and go....just like it's always been. I'm predicting right now that come January, it will freeze in North Dakota.
The Earth has warmed since the end of the "little ice age" which lasted from about 1350 to 1850, a time during which glaciers advanced, crop failures increased, deaths from epidemics and plague were common and Washington crossed an ice-choked Delaware river. So, we were due for an upturn and we have gotten it.
Prior to that, we had the medieval warming period, which lasted from 800 to about 1300. This was when the Vikings were the terror of Europe and Greenland was actually green. Since this starting point, it has cooled.
So as you can see, the warming we have experienced since the end of the little ice-age is not unusual or unexpected at all. And neither is the cooling we have experienced since the medieval warming period.
It all depends on when you start your measurements.
The UK has a few days of hot weather but is not burning up, and the summer overall has been mild and cool.
The US has been mosre more effected in terms of hurricanes and many other such dangewrous weather conditions.
(Waves hand dismissively)..."Ah, that's merely weather, not climate."
This summer in much of the U.S. has been cooler than normal as well. A low of 68 deg. F in Houston, Texas, such as occurred on July 25 and 26, could well be a harbinger of an impending ice age.
While it's still early in the Atlantic hurricane season, 2019 has been mostly quiet in the tropics thus far, due in part to Saharan dust in the atmosphere which tends to inhibit tropical storm formation. 2018 was also fairly quiet, especially when compared to 2017, which was a statistical outlier for Atlantic storm seasons. 2019 has been a fairly active year for tornadoes thus far with 918, but that still falls well within historical norms. 2018 was an average year for tornado activity in the U.S, with 1,123, but a record low in fatalities (10), probably due to the fact that there were no reported EF4 or EF5 tornadoes reported in the U.S. that year.
While there is no escaping violent weather events in the U.S., there are bound to be some years that are more active than others. The overall trend of fatalities due to violent weather in the U.S. is down, due to more robust prediction and warning capabilities. To the extent that property damage from tropical storms may be increasing, the same can be easily explained by population increases (hence, more infrastructure susceptible to storm damage) along the coastlines.
More proof the planet is seeing rapid warming. Just figure all the above normal days i have had the last 8 years vs the below normal days on temps and the above normal days are 90% more.
