Humans are not heating up the planet as much, as quickly as would be needed to keep pace with the runaway greenhouse effect.

My husband can’t believe how cool it is out here. “Look, I’m in the tropics, and temperatures are dropping by 4 or 5 to 6 degrees per year. Maybe it was a big solar flare.” If this were actually caused by humans, a huge meteor strike might have been a big deal, but it’s not. The planet isn’t on the up-and-up. We’ve seen this exact same thing with climate change. It doesn’t make much sense to call the changes in temperatures due to greenhouse gases, when we’re seeing temperatures plummeting by 4 or 5 degrees per year. Some scientists think that warming might well be happening due to that.

“In other words, the planet is in this weird place … It’s an illusion that global warming is caused by greenhouse gases. It’s really the result of an intense Sun,”

The sun is not a greenhouse gas. There was a very nice and brief period in the 1990’s where the sun got super intense. We saw a huge increase in the amount of solar energy reaching the earth. That was a good thing for our plants and the earth’s climate. What happened? The atmosphere warmed, and as a result, the earth cooled by about 0.1C. After that, it cooled back down about 0.8C or so.

However, when the sun returns in about 15, 20, 25 years, there might be a slight cooling, causing the planet to cool back down by a little more than 0.1C. The sun is a big natural (or manmade) source of energy, but that doesn’t mean it can’t do some damage. As we saw over the past few months, those solar storms could take out power. So can the effects of global warming.

“Climate change is the worst example of anthropogenic climate change.” In the past few years, the planet has warmed up a lot. This was caused by CO2, as well it seems. It’s really hard to tell from the heat content of air. But there IS a lot of CO2. So for all to date, humans have contributed about 2/3 of the energy to the earth’s atmosphere. We humans can and will continue to play a role, but it’s been quite passive, at least compared to the energy sources described above. For some reason that just doesn’t fit with global warming. It’s an illusion.

“Climate change has been ongoing for the past twenty years. Why is it so slow? “

Oh geez. This is a good one. You’ve all been very patient so far. The IPCC had no clue as to why the climate was doing and wasn’t doing so hot last century. It had no idea about any of the “global warming.” The reason for the slow warming? Humans are not heating up the planet as much, as quickly as would be needed to keep pace with the runaway greenhouse effect. A lot of it might have to do with the large difference between the Earth’s radiative forcing (the heat trapping effect of other stars in the solar system) and the total amount of energy that the greenhouse effect can pull out of the air. But it doesn’t mean greenhouse gases don’t have any warming effect. Just that the heat trapping effect can’t be seen. All humans can do is make sure they try to take as much carbon out of the atmosphere as possible . Which is why in the past few years, people have been driving cars that are about 50 percent more efficient than they were 20 years ago (which will be done over the next decade or so), because they’re really trying.

“It is a very slow warming, and so the planet is not in a lot of trouble because it could be ice melting and the air is not being warmed.”

For a while there it looked like it might be ice melting. It’s possible. The warming might last a while, but it’s not like we don’t just need to do more to address this. The atmosphere needs to warm. It’s the earth’s core that has to warm up to bring in the planet’s carbon. Or the heat in the ocean is going to be released into the atmosphere quickly. You do think it’s warming slower as a result of that, or a “pump” in the ocean?

“People are now starting to understand that our greenhouse gas emissions are contributing to climate change, which is a positive contribution, but we don’t need to do that much to be doing some good by it. And by that, they are referring to the human effect on climate. We’re not responsible for climate change if, for example, human emissions

Astronomers hope to catch a glimpse of the elusive planet beyond Jupiter by measuring its brightness and detecting radio emissions and other clues, but they're so far away that it will take decades for them to reach their destination. However, if a hurricane is near the center of a large circulation area, where there's already a lot of activity going on, there's a good chance that we might see it move into a strong circumpolar jet.
