HTML-код
- Опубликовано: 21 июл 2015
- This symposium presents varied perspectives from earth scientists, ecologists, and paleoanthropologists on how climate may have shaped human evolution, as well as the prospects for the future of world climate, ecosystems, and our species. Elizabeth Hadly begins with a discussion about A Tipping Point: Using the Past to Forecast Our Future, followed by Naomi Oreskes on Human Impacts: Will We Survive the Future?, and Veerabhadran Ramanathan on Climate Change Mitigation: In Pursuit of the Common Good. Recorded on 05/15/2015. [7/2015] [Show ID: 29685]

Science and technology continue to change our lives. University of California scientists are tackling the important questions like climate change, evolution, oceanography, neuroscience and the potential of stem cells.
UCTV is the broadcast and online media platform of the University of California, featuring programming from its ten campuses, three national labs and affiliated research institutions. UCTV explores a broad spectrum of subjects for a general audience, including science, health and medicine, public affairs, humanities, arts and music, business, education, and agriculture. Launched in January 2000, UCTV embraces the core missions of the University of California -- teaching, research, and public service - by providing quality, in-depth television far beyond the campus borders to inquisitive viewers around the world.

I thought that everyone knew armadillos carried leprosy. Sometimes I'm shocked at just how country I am.
Go to 37:17 if you want to avoid highschool power-point presentations and get (some) hard data.
You're wellcome.
Thanks
The first professor has a nice presentation, it's the second that simply throws text into powerpoint. The third one is of course the best .
Thanks
Models are not data (Rory Tennes), but it is damned hard to make sense of data without a model, because data do not tell you what is cause and what is effect. Granted, a model will not tell you reliably about the future unless you include all the relevant causes you haven't yet thought of. Ay, there's the rub.
Give people more money to live on and population decreases. Education is nice, too, but we don't have that time.
maybe rural electricity was a bad idea.
I'm glad to see the comments section is more measured and calm than the lecturers.
Nuclear might not be perfect, but it would solve a lot of energy problems. Why don't the scientists want to do that?
The nodels predicting temperature rise looks suspiciously like Mann's infamous "Hockey Schtick"!
These presenters all talk about the recent climate change as if it did not exist in the past! What about the historically evident shifts in climate that led to the major changes of whole ecosystems proven through the geological records based on drill cores? The shifts in temperature must have been much larger than the 2 degree Celsius! Our recent societies make the assumption that the climate was always as stable as during the last 500 to 1500 years but the sediment layers show a much higher variability before that time even without the impact of human activity. Statistical correlations do not always tell the whole story and all three presenters appear much too emotionally involved as to be factual.
armadillos just get it in their ears
Hadly's portion (first speaker) was interesting... so humans are causing climate change that will bring on a mass extinction event, yet the most recent examples of extreme climate change did not cause extinctions as much as human hunting? Sounds like she thinks humans are the problem, not climate change. Any time a speaker has the disposition of someone performing a drug abuse intervention I roll my eyes and say "yeah you're right, It's up to me to stop human progress around the world. I'll get right on that."
Humans ARE NOT causing climate change. The climate changes constantly on its own and humans are along for the ride. As for the extinction event 12.9kya that eliminated the Clovis culture along with the other megafauna, humans are totally along for the ride. And so are we...
I'm near certain she isn't right about population growth... from what I've seen the birth rate is falling quite a bit faster than people expect. So, that in itself is at least good news, but the situation for the climate is still 'critical!'
China has recently raised the number of children they allow from two to three. The “one child” rule was abandoned at least ten years ago. It has more men than women because of the old policy. Sons were supposed to take care of their parents.
@@conniead5206 You don't even know your "basic" facts... this is a regime, which is torturing people by the "100 000s!" No, China had a 'one' child policy. Try "growing up" and doing your research please, 'before' you comment?
Thank you so much for sharing. We might weigh/revise our historically vehement stance on "invasive species" to expand and include effects on the genetic mosaic of a geographic area. By increasing biodiversity, we increase the diversity of species assemblages/ecosystems., increase the variability of biological/taphonomic weathering processes, influence weather (relative humidity, soil com[position and characteristics, the list goes on. Should introduced species that play a complementary role (or even one of momentary disturbance be fought? Or channeled to produce adaptive goals that compromise our necessary environmental demands with realities we have yet to fathom or understand, let alone control. Thank you for stimulating so many exciting and essential questions and sharing them with us.
Thanks much!
I remember the years 95'-2001' being some of the most bizarre in my childhood. Historic flooding and then drought in 2007ish I think?
Third Speaker - Thank you for your insight/visual/descrription regarding the water vapor feedback loop. I think of a steam bubble expanding around a nucleus to popping.
The fact is the world's over populated. Each country should really just be living in balance with the amount of sustainable resources it has. No sucking of groundwater
Every living thing is naked
my surname is carta
I am a South American doctor. Armadillos are NOT a public health issue here!
Does this lady really not get that there "WILL" not be 455billion people on the planet in 2250? What is she doing at Stanford then? ....If she can't guess herself ...maybe she should call the local elementary school... or if she needs an academic to believe it: call Westpoint! Unbelievable how stupid a college education can make people!
Also all countries globally are now facing declining birth rate, for e.g jamaica a developing country, the birth rate is so low here and no one seem to care. Human population from hence forth is wolly dependent on the prominent idealogy of the day. Feminisn is gonna kill us all.
A bit disappointing, lots of fear mongering instead of science
I am sure they will spoon feed you some "calming soothing science" soon... you just keep your head in the sand and wait.
Please stay in California and not pollute the rest of America.
This lady needs to go get a real job
Ew, yuck. Climate alarmist narrative!

Wow. Evolutionist all seems to push this idea for an homgenus future.

What a bunch of boring 30 year gargling fantasy. It has long since board me to death. The world has ended so many times in the kast 25 years nobody notced.
