Since when is Hawking a Climate Scientist ? When and where did he get this degree ?

Here is an episode of cosmos: a spacetime odyssee, about this very subject:



Degrasse discusses our nearest neighboring planet Venus and its climate, the climate change on Earth and if it is caused by humans.

My position on this...

If we as a species CAN control the climate, then we most certainly SHOULD.

We live on a planet that cycles from hot to frozen and back again.

If it is within our power to change that, then we would be stupid not to.

As far as climate change goes, I do believe it is real, but as to what extent is it caused by us humans is debatable.


Personally, I don't believe it is debatable, we have most certainly contributed causally to environmental warming across the planet through our fossil fuel burning and dependence. Quite simply, 300 years of our fossil fuel burning has put into the atmosphere trillions of tons of CO2 that would not be there from natural causes alone. Volcanoes, and natural forest fires caused by lightning strikes, for instance, do not in themselves put the amount of CO2 into the atmosphere that pushes the planet into warming or cooling trends in the way we are seeing, nor do they cause permafrosts to melt and release gargantuan amounts of methane from tundra and ocean floors.

If a caldera should erupt and continue to erupt for a certain length of time, then yes, it could cause a short cooling trend of a few years, but what we are experiencing is a continual rising warming trend, year-on-year. Never in our species existence has there ever been the amount of CO2 in the atmosphere as there is today, and there is no abatement to its continual input. Our fossil fuel burning is additional to natural CO2 production. Mechanisms around the planet are quite able to cope with natural production of CO2 that finds its way into the various layers of the atmosphere. Natural CO2 is taken out of the atmosphere into natural CO2 sinks where it gets stored or used and turned back into oxygen, Natural production of CO2 does not overwhelm the mechanisms the planet has for dealing with it, even though environmental pockets around the planet may suffer, and cause hardships to life forms in those local environments.

However, the amount of CO2 we have added to the planet through our fossil fuel burning has to be factored in, and we discover that our CO2 addition tips the scales, not only because of the amount we produce, but also because our continued input of CO2 in ever greater amounts does not allow for any relief to the natural mechanisms dealing with it...we have saturated the carbon sinks, and there is nowhere else for the carbon to go, so it remains in the atmosphere, trapping the heat of the sun within the narrow spectrum between terra firma and the sky, and because it is there, warming is the result.

The warming rises and eventually triggers feed-back loop mechanisms and cause runaway effects that themselves act as causes to other effects, and all are detrimental to the stability of our environments, and their ability to sustain us comfortably. The real issue about global warming and climate disruption is about environment, because the environment is what provides us with our food and the air we breathe, and for the last 300 years we have been polluting them to such an extent that there are now areas around the planet that are not fit for many life forms habitation, including that of our own species.

Over the coming years, the effects are going to worsen, and all we can do is to mitigate the impact of them, we cannot stop it now. Even if we were to reduce our CO2 input the next 40 years will still see a rise in effects, as it takes that long for the effects to be felt. It's not about 'saving the planet', that's a misnomer, the planet will be what it always has been...a planet, regardless of the climate. Environments around the planet will be hit and become quite uncomfortable. Our problems are going to become compounded by many issues, natural and social and cultural and ideological, all of which we are seeing today.

God people forget how warm it may or may not get .
Start with the great barrier reef 25% DEAD bleached DEAD and dieing fast mostly from pollution RUN off factory and farm . Now that area is a Major Fish spawning ground a Major food source for much of the 7 billion people .
It dies we die . But lets not stop there the gulf of mexico is on the verge of total collapse .
3 dead zones and pollution is so bad even here were i live the alge is off the charts and fish are dieing .
It is happing all over the world .
WE Earth needs the. oceans without them you wont be worried about the heat .
www.google.com...
click THAT LINK AND TELL ME MAN IS NOT EFFECTING HIS ENVIRONMENT AND TO THE POINT WERE EXTINCTION IS A FACT .
this is our legacy so much garbage the worlds animals chock on it .
200 years agaio 10 million buffalo now a hand full ( Africa was teaming with animals now most on the verge of extinction over 100 species goin extinct every day .
and your worried about 1000 years from now ? your grandchildren will be chocking to death with teh filth we have made

The military is concerned about climate change.

www.scientificamerican.com...

www.military.com...

So who do you believe?



The military and Hawkings plus other reputable scientist... or...the fossil fuel industry and their paid for scientist?

of course the right wing will side with the energy companies and when Florida is under water...whine ...."why didn't someone warn us"


When the military gets involved and claims something, history proves it to be the direct opposite.

Hawkings is a crazy imbecile who used to be smart about math. Not political money making schemes for a-holes and pieces of crap like Al Gore.

Any scientists who get their funding federally are all suspect and by definition are far from credible. As they have already proven OVER AND OVER again.

And even if everyone accepted it? What actions are going to stop it from happening, wishful thinking on the part of those who believe this crap? When there is a problem, governments that know how to fix things do that first, and then everyone says "Good Job!"
Now for some reason they want to do it backwards? Get everyone to believe it's real first, then they will tell us how it's going to be fixed?
Right now the solution seems to be to just get all populations of people to believe it is real, and that it can be fixed, without providing any actual solution.
LOL

Global warming killed the buffalo?

And you might want to do some throrough research on the great barrier reef instead of listening to the Main Scream headlines, it's not as bad as you think.

As the global warming bubble deflates, another one will inflate. The next one I expect is ocean acidification. Should be good for a couple years before it too gets debunked. (not that it already hasn't).


As far as extinctions go, it's not global warming and C02 doing it, so get off that track.

Humans have shrunk the habitats of many life forms, through unsustainable agriculture, fishing or hunting. And it is going to get even worse. Global warming is said to be threatening thousands of animal and plant species with extinction. That, at least, is what the Intergovernmental Panel on Climate Change (IPCC) has been predicting for years.

But the UN climate body now says it is no longer so certain. The second part of the IPCC's new assessment report is due to be presented next Monday in Yokohama, Japan. On the one hand, a classified draft of the report notes that a further "increased extinction risk for a substantial number of species during and beyond the 21st century" is to be expected. On the other hand, the IPCC admits that there is no evidence climate change has led to even a single species becoming extinct thus far.

You curtail it before it reaches a point of cascade, somewhere north of 400ppb.

C02 is currently at 400 parts per million. If you don't know the difference between parts per billion and parts per billion, your opinion really doesn't mean much.

Pulling out of the Paris agreements does not mean we go rampantly ignorant about pollution and climate change. There are many controls that will stay in place and perhaps get more stringent. It is an application of the 80/20 rule. Concentrate on the 20% that contributes to 80% of the problems. Make it manageable without hurting industries that are in the contributing minutia.

Really, how much can CO2 actually do?

CO2 makes up only 0.04% of the atmosphere. That is the tinniest amount and yet it magically traps all of this heat ... all by itself.

Nonsense.

So is man made global warming.

The Planet has been getting warmer for the last 18,000 years and it is supposed to do that. It is cyclical in nature.

Winter is coming. That is the only reality.

Steven hawken is trying to remain relevant after his black hole theory tanked. Hes a paid shill.
