Yes since humans have been using fossil fuels the climate has increased .0 3%. But if you look at the models that's about where it would be anyhow.

Ide love to suggest a video! As a long term botanist, I think a cool video would be about how plants are actually much smaller than what we see. The liveing (tree) organism is actually just the leaves, roots, and just a few layers of tissue below the bark. The rest is just wood, (dead mineral deposits,) serving only as a sanitary structure for the (TRUE ORGANISM) to colonize! And just like how algae MUST asists corals, micorhiza MUST be present to grow trees. 🙂hopefully it's enough to inspire the team

Learning about Earths climate is really good. It teaches us about how Earth has changed in the past and can show us about just how much Human caused Global Warming might be effecting the planet in different ways. Hopefully we can put together the climate story eventually and completely accurately see Earths climate. Until then we’re still learning but we definitely know enough to know Humans are having a negative impact on our climate.
We can curb our bad environmental habits, but we should be more concerned with a pending magnetic pole flip which will be with major storms and chaos..we have a sun coming for us as it begins to ramp up its new 11 yr cycle and with a weakened magnetic shield all ready we are needing that as news -not pointing tiny fingers at global warming, which would flip to a frozen world fast...very fast....

3:48 "because water becomes slightly acidic as it picks up CO2" ... Generally good but that one contributes to a FALSE impression. Carbonic acid is a very weak acid, we have it in our bodies, the oceans are alkaline at pH 8.11. Carbonic acid can make that water slightly less alkaline but the notion that our oceans are now acid and becoming "more acidic" is terrifying and a common falsehood being perpetuated, our oceans are basic (alkaline). Look up ocean slowing, it means the upper warmer layer can't absorb as much CO2 and has been happening for 200 years. 2013: "The oceans as a whole have a large capacity for absorbing CO2, but ocean mixing is too slow to have spread this additional CO2 deep into the ocean. As a result, ocean waters deeper than 500 meters (about 1,600 feet) have a large but still unrealized absorption capacity, said Scripps geochemist Ralph Keeling" . Also I understand the ocean floor basalt is alkaline and also a factor due to the reduced mixing now.

Even when satellite data showed that now famous ozone "hole" over the Antarctic they continued to spread misinformation and attack both the science and it's supporters. And that continued right up until ozone-friendly HFC's were created, at which point the objections to the science all magically disappeared. More recently there's been the anti-vaccine movement. There were lots of people, some of whom are (poorly regarded) scientists claiming that vaccines cause autism. Then Covid-19 happened and all of a sudden they've gone quiet. My point is that to me the climate change debate looks very similar to that of the ozone debate of the 80's. I see the same PR strategies being used against the science and I see the same anti-science mentality that the anti-vax'ers use right down to the repeated use of thoroughly debunked arguments and an almost complete lack of understanding / desire not to know. Even today there are people who think that CFC-induced ozone thinning is a scam, so if like them you're religious about this subject then there's probably nothing I can say to change your mind. Reality is always right and it will catch you out eventually. Otherwise be careful; to find the truth play both sides off against each other and remember there are firms out there that specialise in getting you to vote against your own interests.
@@loc4725 I completely agree with you. The problem with climate science is that there is currently no way to quantify the effect of CO2 concentration to the global warming. If you calculate it analytically without feedbacks, you get much much smaller equilibrium climate sensitivity (ECS) than the range asserted by IPCC. They argue with unknown positive feedbacks to justify their positions. However, even scientists don't really know how strong those feedbacks are. Furthermore, if these feedbacks were correct, the climate system would be so unstable, that it would oscillate between glacial and interglacial periods much more often (like any amplifier with feedback). Another problem I see with it is that current climate models are based on assumption, that CO2 is primary temperature driver. But they fail to reproduce the climate variability in the past. They can only reproduce the overall trend (almost without variability). There are also studies that tried to run these models with different set of assumptions (i.e. that the effect of CO2 is smaller than the effect of long term sun variability) and were much more successful in reproducing the past climate including decadal variability and trends. However, the IPCC ignores them completely, because they show that the ECS is much smaller and that the modern era warming was mostly due to sun long term variability and only 0.12 C was caused by CO2. And no, I don't "believe" that CFCs are not destroying ionosphere. And I would like to know how you came to such idea. Was it an attempt to justify your position?

Because surely most people saw that, but you gotta make sure. It's not just your right but your DUTY to spread the word about what you just saw and what you think about it. Is that right? Or is is just online where you're anonymous and behaving like that has no social consequences to you? Think about that. I gain nothing from telling my neighbor I think his nose is big, and there's a possibility I might hurt his feelings by saying that.

I suspect other people have noticed the size of his nose too, and they probably would agree it's big. -> I don't feel hypocritical at all if I don't comment on his nose in any way. Not face to face, not anonymously online. I simply don't feel the need to point it out since it's irrelevant in my interactions with him, I gain nothing positive from saying it, and he potentially takes it negatively. I feel it's the perfect opportunity for me to exercise my right to shut the f up. I don't stay up all night thinking "I'm so dumb for not letting everyone know what I think about his nose..." There is absolutely nothing dumb or hypocritical in not letting all your brain farts out. His weight is non of our business and should also be irrelevant since we're not watching an episode of America's next top model. If you want to act like an ass, you absolutely have the right to. But just because you can do something doesn't mean you should. Not saying out loud everything you think is not a form of dishonesty, it's good judgment and maturity. Refraining from saying something that might hurt someone's feelings when you gain nothing from saying it, even when that's what you think and suspect others are thinking too, is not hypocritical it's just empathic, smart and kind.
I have a few quartz crystals with what they call enhydro inclusions. This is water trapped within the quartz. One has several different enhydros so whichever way you move it you see water moving around. They are really fun to look at! I always wonder about what that water "saw" when it fell as rain!
Climate change is something that we can all come together and make a difference. I’m majoring in marine biology and I am dedicating my channel to marine life and I am hoping to make a huge difference in the future !
All things Marine thank you for your work. I know global Warming is having a negative impact on the oceans but just what exactly effect is it doing on the oceans?
There may be data point correlation between magnetic wandering and axial shift but, I don't see how magnetic pole reversal would affect global weather patterns. There is talk of magnetic field strength affecting the upper atmosphere. Mainly that solar wind, aka charged particles, and the affects it has on the upper atmosphere holding in global heat. But the reversal of magnetic north and south in and of itself wouldn't change a whole lot.
Yes and no. Yes, as in, both Carbon Dating and the analysis used for the things in the video use mass spectrometry. No, as in, C14 is an unstable nucleus, which decays over time. The isotopes used in the cited papers are stable.
I feel like rock deposits & formation have been the jist of at least 2 of the points in this video. Rock deposits, and the lack thereof, literally tell you everything about something from it's age to how things were back then etc. With some rock deposits you can even judge what the location of the earth's magnetic pole was among other things.
I feel so stupid for asking, but is it possible through bat guano or anything bat based used as fertilizer to have caused a covid 19 outbreak over just eating a bat (as is "apparently" the case) instead? Sorry for the stupid question. EDIT: had to add quotes to get my point more across
UK region is very sensitive to long term solar activity changes. Currently it is in historical minimum. If it will last longer, UK region may be cooling over time. Similar to last LIA (little ice age). But probably not so much as now we have more CO2 in the air.
It's an annual climate pattern that occurs at these days, marked by very cold temperatures for like a week. In germany they are called Eisheilige, which, directly translated, means ice saints. Don't know what causes it though. So this isn't a thing in the UK normally?
Slow, GRADUAL climate change, like that in ancient times, is pretty easy for life to adapt to. RAPID climate change, like that we are now experiencing, does not allow sufficient time for evolution to occur and adapt the animals to the new conditions.
Read "The Sixth Extinction" by Elizabeth Kolbert, it describes the impacts of the kind of rapid climate change that we can expect this century on our current CO2 emissions path: scripps.ucsd.edu/programs/keelingcurve/wp-content/plugins/sio-bluemoon/graphs/co2_800k_zoom.png These two-page Highlights from NASA, NOAA and others make our problem clear: science2017.globalchange.gov/chapter/executive-summary/ So are the risks and impacts: nca2018.globalchange.gov/ Life will come and go, but why would we want to kill off 25 - 50 percent of all currently living species during our time? That's not going to be a great thing to live through. And there is no reason for it. There are effective, fair, and beneficial solutions we could use now like citizensclimatelobby.org/basics-carbon-fee-dividend
Um, no it hasn't! I mean, "Life" as a broad term? Yeah, I guess so. But out of the 99% of all species ever that are extinct? Climate killed, like, 90%. And we killed, like, 5%.

Martini is a wino That was 12,000 years ago. We should actually be heading back into a glacial period in 10,000 to 20,000 years but humans are now causing Earth to warm
You are aware, aren't you, that the changes from Climate Change could easily explain that? Especially the changes in the ocean currents that will change the temperatures in local areas. They can easily cause lower temperatures in one area while temperatures overall still go up.
How about using real science to look at the past. At one point co2 was well over 3000 ppm and the earth was in a major ice age. IF co2 is the control knob alarmist claim, that would have been impossible.
First of all, there are multiple "control knobs" and no one has claimed that CO2 alone determines climate. Solar output is another "control knob," and it was less during the Ordovician than at present. Past studies on the Ordovician period calculated CO2 levels at 10 million year intervals. Such coarse data sampling couldn't capture data for the Ordovician ice age, which lasted only half a million years. Recent studies determined that, during the late Ordovician, rock weathering was at high levels while volcanic activity, which adds CO2 to the atmosphere, dropped. This led to CO2 levels falling below 3000 parts per million which was low enough to initiate glaciation - the growing of ice sheets. See: Young, Seth A., et al., 2009, Geology, 37 (10): 951-954.

No, you were not, stop lying. No scientist or a well educated teacher would say something like that. You know why? Because even someone with rudimentary knowledge of climate science would know the difference between naturally occurring climatic changes and man-made global warming.
And you even liked your own comment. How much more pathetic can you get?
@@ProfezorSnayp how can you tell someone liked their own comment? I have suspected people did that but no idea how to look and see.
@Eric Eveland no
@Eric Eveland Pseudoscience garbage.
He not doing well with this Quarantine
Is it just me, or did he gain a little weight, great show though
Does it matter if he did? Just enjoy the show!
@@user-mt8fl2cm7x blow me I'm entitled to a option and that's mine
It's one thing to have an opinion and another to be dumb enough to say it out loud.
@@user-mt8fl2cm7x It would be dumb and hypocritical to not say what you think. Everybody who wonders if he "took some weight" can now see there are more people who noticed it too.
@@ae693 If someone falls down on the street, do you immediately yell at everyone around "He tripped! He fell!! Did you see? You saw that too right?!" Because surely most people saw that, but you gotta make sure. It's not just your right but your DUTY to spread the word about what you just saw and what you think about it. Is that right? Or is is just online where you're anonymous and behaving like that has no social consequences to you? Think about that.
I gain nothing from telling my neighbor I think his nose is big, and there's a possibility I might hurt his feelings by saying that. I don't really know him so I don't know if that's a sore spot for him. I suspect other people have noticed the size of his nose too, and they probably would agree it's big. -> I don't feel hypocritical at all if I don't comment on his nose in any way. Not face to face, not anonymously online. I simply don't feel the need to point it out since it's irrelevant in my interactions with him, I gain nothing positive from saying it, and he potentially takes it negatively. I feel it's the perfect opportunity for me to exercise my right to shut the f up. I don't stay up all night thinking "I'm so dumb for not letting everyone know what I think about his nose..."
There is absolutely nothing dumb or hypocritical in not letting all your brain farts out. His weight is non of our business and should also be irrelevant since we're not watching an episode of America's next top model. If you want to act like an ass, you absolutely have the right to. But just because you can do something doesn't mean you should. Not saying out loud everything you think is not a form of dishonesty, it's good judgment and maturity. Refraining from saying something that might hurt someone's feelings when you gain nothing from saying it, even when that's what you think and suspect others are thinking too, is not hypocritical it's just empathic, smart and kind.
Woh, you've put on a lot of weight!
Fossilized water is one cool thing I learned today.
Lakshmi Mohan same! Love little nuggets of knowledge like that
ait until you hear about fluid inclusions.
@@TommoCarroll cool channel you have. 😊 Just subed now.
I have a few quartz crystals with what they call enhydro inclusions. This is water trapped within the quartz. One has several different enhydros so whichever way you move it you see water moving around. They are really fun to look at! I always wonder about what that water "saw" when it fell as rain!
So, what do you do for work?

Eric Eveland I have not heard of that! But I shall look into it!
All things Marine thank you for your work. I know global Warming is having a negative impact on the oceans but just what exactly effect is it doing on the oceans?
There may be data point correlation between magnetic wandering and axial shift but, I don't see how magnetic pole reversal would affect global weather patterns.
There is talk of magnetic field strength affecting the upper atmosphere. Mainly that solar wind, aka charged particles, and the affects it has on the upper atmosphere holding in global heat. But the reversal of magnetic north and south in and of itself wouldn't change a whole lot.
@Eric Eveland when calling people idiots is your only argument against something someone says then you have no argument.

Climate change and global warming are a major issues and need every nation's attention. Good Job

@Eric Eveland Both anthropogenic climate change and magnetic pole reversal are real phenomena. They also have nothing to do with each other.

@@jasper3706 or the amount of CO2 in the atmosphere.
So it's like carbon dating, which tells you how old an object is.
Yes and no.
Yes, as in, both Carbon Dating and the analysis used for the things in the video use mass spectrometry.
No, as in, C14 is an unstable nucleus, which decays over time. The isotopes used in the cited papers are stable.
I feel like rock deposits & formation have been the jist of at least 2 of the points in this video. Rock deposits, and the lack thereof, literally tell you everything about something from it's age to how things were back then etc. With some rock deposits you can even judge what the location of the earth's magnetic pole was among other things.

Similar changes happen all the time (i.e. MWP and then LIA). Only time will show how sensitive the climate really is to CO2 concentration.
Very informative video thanks a lot sir
I feel so stupid for asking, but is it possible through bat guano or anything bat based used as fertilizer to have caused a covid 19 outbreak over just eating a bat (as is "apparently" the case) instead?
Sorry for the stupid question.

Calling it guano does not change the fact that it's batshit. Crazy...

Because they don't know the location and just assume it's the right way around.

Yesterday it was 20C in the North East UK, today it was 4C with big fat hail. What on earth is going on
Some kind of... Change.... in the Climate...
Global warming.
UK region is very sensitive to long term solar activity changes. Currently it is in historical minimum. If it will last longer, UK region may be cooling over time. Similar to last LIA (little ice age). But probably not so much as now we have more CO2 in the air.
It's an annual climate pattern that occurs at these days, marked by very cold temperatures for like a week. In germany they are called Eisheilige, which, directly translated, means ice saints. Don't know what causes it though. So this isn't a thing in the UK normally?
That’s weather not climate

So early that the climate changed
Life sure has survived a lot of insane climate change over millions of years.
Slow, GRADUAL climate change, like that in ancient times, is pretty easy for life to adapt to. RAPID climate change, like that we are now experiencing, does not allow sufficient time for evolution to occur and adapt the animals to the new conditions.
Read "The Sixth Extinction" by Elizabeth Kolbert, it describes the impacts of the kind of rapid climate change that we can expect this century on our current CO2 emissions path: scripps.ucsd.edu/programs/keelingcurve/wp-content/plugins/sio-bluemoon/graphs/co2_800k_zoom.png
These two-page Highlights from NASA, NOAA and others make our problem clear: science2017.globalchange.gov/chapter/executive-summary/
So are the risks and impacts: nca2018.globalchange.gov/
Life will come and go, but why would we want to kill off 25 - 50 percent of all currently living species during our time? That's not going to be a great thing to live through.
And there is no reason for it. There are effective, fair, and beneficial solutions we could use now like citizensclimatelobby.org/basics-carbon-fee-dividend
Um, no it hasn't! I mean, "Life" as a broad term? Yeah, I guess so. But out of the 99% of all species ever that are extinct? Climate killed, like, 90%. And we killed, like, 5%.
It would be a bit tricky to claim that recent transition from Paleocene to Holocene was:
- slow;
- dooming humans.

You are aware, aren't you, that the changes from Climate Change could easily explain that? Especially the changes in the ocean currents that will change the temperatures in local areas. They can easily cause lower temperatures in one area while temperatures overall still go up.
It may be also explained by unusually low solar activity.
Global warming is, as the name implies, a global climate phenomenon.
Local cool weather is... a local weather phenomenon.
Wow, that's bat-guano crazy!
How about using real science to look at the past. At one point co2 was well over 3000 ppm and the earth was in a major ice age. IF co2 is the control knob alarmist claim, that would have been impossible.
First of all, there are multiple "control knobs" and no one has claimed that CO2 alone determines climate. Solar output is another "control knob," and it was less during the Ordovician than at present. Past studies on the Ordovician period calculated CO2 levels at 10 million year intervals. Such coarse data sampling couldn't capture data for the Ordovician ice age, which lasted only half a million years. Recent studies determined that, during the late Ordovician, rock weathering was at high levels while volcanic activity, which adds CO2 to the atmosphere, dropped. This led to CO2 levels falling below 3000 parts per million which was low enough to initiate glaciation - the growing of ice sheets. See: Young, Seth A., et al., 2009, Geology, 37 (10): 951-954.
If you had read up on climate science, you would have known that there isn't any singular "control knob".
Hiii
