„There is nothing more dangerous to science than blind passion. - Given support from someone in power, it can lead to suppression of true science and, since science is now a matter of state importance, to inflicting great injury on the country.“ Nikolai Nikolyewitsch Semyonow (Nobel Prize in Chemistry 1956): Science Does Not Tolerate Subjectivism, Science and Life, 1965

I believe in climate change ... it happens 4 times a year in most of the world.... just saying. Real fluctuations are driven mostly by solar and Milankovitch cycles. We humans actually can affect the local effects by planting trees to mitigate erosion and protect water sources. It is thought in some circles the mini ice age in Medieval Europe was mitigated by burning more coal and wood, but I do not know how true that is. I noticed during the "covid" panic that the temperature and air quality improved within a month. So from that I think we can say a shift to electric vehicles and better battery manufacturing will help. So will planting more trees. We already have a robust and active tree farming industry so we can expand it to help cycle and control the carbon dioxide levels. As for this so called carbon sequestration currently in vogue, every living thing on Earth contains carbon. It is a part of life. Locking it into non-cyclic sources can only harm the environment. Trees, plankton, chalk and limestone formations, and reefs are all natural ways of taking care of excess CO2 and they work millions of times better than any man made attempt. For millions of years longer than we have been here. Just saying.

I just finished watching something about old DNA found in soil and the fact that oceans were way warmer than today... food for thought. We may have evidence there's a human made warming, but we also have evidence saying the climate was warmer in the past, among other things that contradict the climate catastrophe theory.

Stop CO2 fully... The other Shoe 👠....look up the sensitivity of CO2 as a Greenhouse Gas. Ratio the more CO2 the less the effect in the Atmosphere as a WARMING AGENT. The Current Global Temperature 🌡️ about 14.2 degrees. 418 ppm CO2. During the Dinosaurs Reign 3,000 to 6,000 ppm CO2. Between 25 to 30 degrees Celsius. 18,500 years ago..... 8 Degrees. CO2 about 160 ppm.

The climate has been warmer in the past several times, the issue is the rate of warming you daftie

ANARTIC ICE CORES TELL US THAT FIRST IT GET WARMER THEN CO2 INCREASES .

ANARTIC ICE CORES TELL US IT GOES EITHER WAY

[@rps1689]

Anyone in science knows how temperatures can rise and fall independently regardless of the CO2 levels, but there is a strong correlation between rapidly rising atmospheric CO2 and rising temperatures. It's one of the most widely accepted rules in geological history. What we have seen in the last 200 years is an incredibly rapid increase in geological time; in geological time, 200 years is practically tomorrow. To give you an idea, the current observed global warming is happening twenty times faster than any natural climate change visible in the paleoclimatic record; i.e., faster than it occurs naturally in the geological record.

Oh i also need to see this highway that just melted away….. given that most of us know what highways are made of and what the process is in making it.

There is no "Climate Crisis", and if there is..... then give me proof? Open the door, walk outside and breathe deeply, smile, and then take a kid fishing :)

“Is there any other reasonable explanation”, yes there is and you scoff at it. The sun. “Brightness” is not the only way the sun contributes to our climate. All ipcc data drastically undervalues the sun’s impact. She shows her ignorance/bias, “the sun isn’t getting any brighter”. Do yourselves a favor, go look at the reasonable theories presented by SuspiciousObservers and give it HONEST consideration.

True. Miami was supposed to be under water 30 years ago. Same with some of the islands that are only a few feet above sea level and are still here.....

@@robertbrowning7556 No such claim nor prediction was made by mainstream climate science.

[@rps1689]

Name one from mainstream climate science. The notion that all mainstream climate science predictions have not materialized (in the words of “skeptics” - “all the predictions have been wrong” is not only inaccurate, but it is one of the most stale and tired talking points from the organized opposition to climate science. Some of the things that were predicted by main stream climate science that materialized: Planet greening, global average surface temperature will rise due to added greenhouse gases, nuisance flooding in low lying cities will get more frequent, sea level rise will accelerate due to thermal expansion and land ice melt, CO2 fertilization, agricultural hardiness zones and wild species ranges moving poleward, the Arctic warming faster than the equator, the stratosphere cools while the troposphere warms, marginal farmland going out of production, causing refugee flows and political instability, increased rate of species extinction, tropical pest species invading the subtropics. Subtropical pests invading temperate zones, and permafrost melting. More predictions are still on track.

@@bondo6506 Fact is CO2 is not only a life giver, it is also a waste product from fossil fuels that has made some ecosystems, agricultural zones, and feeding grounds we depend on not adaptable enough to the current climate change trend.

It's like saying if we had a hot day tomorrow or a thunderstorm. Your basically asking people to make that stop. Which is a joke. Things will be fine when people leave it alone. Trying to intervene in nature. If people die than it supposed to happen. You can't stop it. It's like final destination. It will happen anyway.

"Zero" No thanks.

[@johnjrgensen701]

Really fine talk, Thanks Corinne. I wonder where the other half of the talk is? Is it coming soon? NASA and IPCC tell us that even a complete stop for CO2e release, will be too little too late. So what is the other half? Our climate has 2 main drivers. The greenhouse gases and the water cycles. Water cycles is said to control 90% of the heatbalance of the blue planet... Simply by looking into this area, we will empower ourselves to act, you and me in our own local community... It will work from day one, most where drought is a problem. Look to M. Kravcik "A new water paradigm" for more info...

The hypothesis has been tested? Wow she can travel in time….. Hmmm, why is it the Models she cuddles nightly haven’t gotten the future years correct NOR even the past years. She surely puts a lot of confidence in computers and software, despite their overtly high error rates. But despite all that, the real high to climb is FORCING the billions of poor people that want NOT to be poor and fossil fuels is unfortunately today, the only dense and fairly cheap source of power and like it or not, that is a fact. Who are we to tell or attempt to force the poor of the world not to do as we have done and still do? That’s pure Hubris if I have ever saw it.

Every year I think 'where are our thorium reactors? Why do we put so much effort in half-baked solutions like windturbines?'

Because every nutcase scientist and inventor who is ready to go public with their zero point energy device, suddenly feels the urge to kill themselves, die in freak boating accidents, are beaten to death in an airport parking lot, or just suddenly disappear.
