Global warming, so confusing, help me understand.

A shift in the polar vortex could bring a blast of Arctic air to millions of Americans in the second half of March, forecasters have warned.

The polar vortex usually keeps cold Arctic air confined above the North Pole, but experts believe it is starting to shift and stretch. That disruption could create the conditions for springtime snow and storms in the central and eastern U.S., according to a statement released by weather website.

The polar vortex isn’t just a term for winter weather—it’s a significant force that could shape the future of our planet’s climate

I am skeptic about global warming. When the COVID period kept cars off the roads the temps went up from what I understand. No "smog" to provide a layer of insulation from the sun.

Climate change I can agree with.

The earth does not perfectly spin without some wobble. That insignificant measure of wobble can change the axis.
The axis change creates the changing of the climate.

I am not a scientist but, I did stay at the Holiday Inn last night.

Yea everyone knows the climate changes, it has gone through ice ages. The question is, how much effect, if any, do we have and if that effect is positive, negative, or neutral overall. Also if there are positive ways we can effect the climate on purpose. What I never hear is what the optimal climate is. Any change must be bad as if right now we are in optimal climate.

Bingo! The alarmists never answer the question.

Stop blaming on Global warming.
Weather changes throughout time. Live with it.

Perplexity AI:

"The Earth’s future temperature trajectory depends heavily on greenhouse gas emissions and mitigation efforts. Based on the most recent scientific research:
Warming Projections for the Next 50 Years (by 2075)
• Baseline Trend: Global temperatures have been increasing at a rate of approximately 0.18°C per decade since 1970, which suggests a warming of about 0.9°C by 2075 if this trend continues unchanged.
• High-Emission Scenarios: If emissions continue to rise rapidly, models project warming of at least 2.7°F (1.5°C) to as much as 8.6°F (4.8°C) by the end of the century, with significant warming likely occurring by mid-century.
• Mitigation Scenarios: Aggressive reductions in emissions could limit warming, but even under optimistic scenarios, some warming is expected due to existing greenhouse gases.
Warming Projections for the Next 100 Years (by 2125)
• High-Emission Scenarios: If emissions remain unchecked, global temperatures could rise by at least 5°F (2.8°C) and possibly up to 10.2°F (5.7°C) above pre-industrial levels by the end of the century.
• Moderate Emissions Decline: If emissions begin to decline significantly by 2050, warming could still reach between 2.4°F (1.3°C) and 5.9°F (3.3°C) by the century’s end."


A warmer Oregon would be a good thing. Cultivating wine is more profitable than growing grass seed.

r winter weather—it’s a significant force that could shape the future of our planet’s climate

zzzzz. Just because no one called it the "Polar Vortex" doesn't mean it hasn't been around a long time. When in High School we got a 14" snow storm, March1968. Record still stands. During the depression it was not only hot summers but it was cold winters. On 11-11-1911, a blue norther came through the Midwest deep into Texas and Oklahoma setting record lows and highs on the same day.

The stratospheric vortex's SSWs were discovered in 1952 with radiosonde observations at altitudes higher than 20 km. The tropospheric polar vortex was mentioned frequently in the news and weather media in the cold North American winter of 2013–2014, popularizing the term as an explanation of very cold temperatures.​

That means the IPCC (Intergovernmental Panel on Climate Change) is full of **** then and they are the ones writing the book, right? The Representative Concentration Pathway (RCP) 8.5 is a climate change scenario that assumes the world continues to burn fossil fuels at the current rate but with no environmental controls and all new plants basically coal fired. It is not only a worst-case scenario, but the IPCC says that it is not even a possibility. The RCP 8.5 is triple the current level. (RCP means there is 8.5 watts of heat for each square meter of earth, again that is 3x the current amount. And finally, even if we reached RCP 8.5 there is no guarantee that the models claiming the doomsday "tipping point" would come true. It is speculation that it would. PS- The world has been about that temperature before, the polar caps were melted and the world did not end.

With no tax credits the whole industry kind of dies. The issue has never been about climate change it was just a big government scheme to force things on people under the guises of fear. Notice nobody's talking anymore about the new green deal or how we're all going to die in 12 years... lol
