The Nonsense of Trudeau's climate change policies

Well, thanks for the Lomborg compliment but inadequate information is a  bigger lie than no information so let's hear the rest of the "Climate Change" story:

https://rgsweather.com/2013/03/28/who-killed-spring-2013-suspect-6-climate-change/

During the time of the dinosaurs CO2 was about 4 times higher than today. So this idea carbon dioxide levels a quarter of that will destroy all life on earth is a lot of hooey. 

Are we living in the time of the dinosaurs? If you weren't aware of it, our Sun has been slowly growing hotter as time goes by, and was much cooler 250 million years ago when those dinosaurs started developing. 

The worst mass extinction since the rise of multicellular life forms gave the  dinosaurs and other reptiles their big break! Because our mammalian ancestors were also starting out at the same  time as the reptiles( and dinosaurs) during the late Permian era about 250 million years ago, until the Earth's land masses started breaking up, unleashing a chain of massive volcanic activity...like the creation of the Siberian Traps...the large volcanic balsalt flood plain that covers more than a quarter of Siberia's land mass today. At the end of the Permian, the Traps was like an open wound in Planet Earth...oozing lava slowly and gradually for one or two million years, until they became dormant again and carbon dioxide levels could fall and the remaining life after the mass extinction could go on.

The long, deadly P-T Extinction gave an early advantage to the reptiles over our mammalian ancestors at the time for unknown reasons, and had to live in the margins...most early mammals burrowing underground where it was a little safer and easier to survive the 180 million year eras of dinosaurs roaming the earth. There were two mass extinctions separating the first era of dinosaurs - Triassic, from the era known for the great sauropods - the Jurassic. And another extinction that led to the final dinosaur era - Cretaceous...where T-Rex and Triceratops battled it out on open plains. And of course, mammals wouldn't finally have their chance to be the dominant group of animals until an asteroid hit (combined with volcanic activity of the Deccan Traps...which had been caused by the runaway Indian Continent moving north and crashing into Asia. 

So, to sum it all up, a mass extinction paved the way for the rise of dinosaurs, and two major extinctions separated three eras of dinosaurs, until finally, the dinosaurs were all gone because of an asteroid hit and the forming of the Deccan Traps 63 million years ago, cleared the dinosaurs and other major reptile species (except for birds) paved the way for our mammal ancestors to finally take the stage. 

What this all should tell us is that our planet's long history is far too complicated and still too full of gaps to make simplistic then and now comparisons! 

*the gradual increase in solar output over time is why our planet's atmosphere transitioned from heat-trapping to becoming more and more heat-expelling as it first lost all of its methane and ammonia 2 billion years ago, and the first lifeforms expelling oxygen as a waste product gave rise to plants. During those microbial world times, oxygen levels rose, the last heat-trapping gas - CO2 began a long steady decline in atmospheric content that is still going on today.....until humans decide to industrialize and fuck it all up! 

And that's why you can't compare then and now over an expanse of millions of years! The earliest modern humans only came along less than 200,000 years ago. And any claims of what our climate should or should not be, need to account for how our ancestors lived and what they had to adapt to as they moved out around the world and tried to live and survive in as many places as possible.

There are many hypotheses concerning the period of the dinosaurs. People often grab one and post it as accepted fact when it suits another hypothesis they`d like to make.

All I`m saying is life was teaming during a period when Carbon Dioxide was multiple times what it is today.

That is accepted fact.

I'm not too worried about species becoming extinct. That's been happening since the world began to form life. It's been estimated that 99.9% of all species which ever existed on Earth are extinct.  I really only care about ours. 

And no one has been able to show the only proposed solution which might, possibly slow global warming (maybe!) sometime in the future is even remotely doable given the state of International politics and  cooperation.
