Just To Let You All Know... Laki's big sister is threatening to erupt. Here's the current activity, as of 7:12 Iceland time: Iceland evacuates area near Bardarbunga volcano I also wonder if many of the quakes that have plagued areas of the world has anything to do with the moon being it's closest to earth at this time.
Interesting info..and scary. But this post will go nowhere. There's nothing in it that the liberals can use to condemn mankind for their reckless ways. It has to have a 'hook' and a viable target group to attack. Something that that target group can be regulated for.
Hmmm,... A very cold season will come after such an event, though. That will allow them to forget about their claims of Global Warming for a while.
No doubt a large volcanic eruption would significantly lower global temperature, just as Mt Pinatubo did in 1991, but the effects will only last a few years while CO2 remains in the atmosphere for about a century.
Not according to climate models however which all over tune volcanic eruptions do CO2 can have a larger net forcing. According to the modrls BEST used to discount the 17th and 28th century cooling Pinatubo should have sent us into an ice age.
Here are results of the BEST models you mentioned and Mt Pinatubo appears to fall right in line with observed temperatures.
pinatubo being a small insignificant pop compared to tambora...unless the volcanic eruption is massive and sustained like the siberian or deccan traps the effects while noticeable are short term...
Actually if you look at your graph with a skeptical mind it proves my point. All the pre mid 19th century eruptions are modeled. Its largely model output saying what the eruptions did to global temperature. They know that the era was exceptionally cold so they have modeled the response to a volcanic eruption to fit their theory of high CO2 sensitivity. The problem is look at the timing. They are blaming a volcanoes for causing coolings that started before the volcanoes blew. Sure a first look statistical glance might show a good enough correlation but once you realize that volcanoes appear to be traveling back in time it becomes a joke. Using the volcanoes as an excuse for the cold period allows them to keep the climate sensitivity of CO2 very high. If they modeled the climate response to a volcanic eruption more realistically they would have to lower the CO2 sensitivity. Tambora was no doubt a powerful eruption but I doubt that it has the ability to time travel and cause a cooling 2 decades before the eruption occurred.
Who has wondered at all the noise being made over a small change to temperatures over 150 years of time? I for one, am pleased we are leaving an ice age. Remember when the Great Lakes were a glacier? I wonder why the boys at climate alarm, inc don't discuss this has been the history of earth. Ice melts, things like the Great lakes are left behind. There is no particular reason to blame humans.
Tambora was a major eruption no doubt but look at how they model Laki. Look it up. Laki wasn't that significant. It was way lower on the significance scale than Krakatoa yet they model it as having an effect almost as strong as Tambora which was an order of magnitude more powerful. The difference is that there is very little data for Laki so BEST can model its effect as what ever they need to fit their theory. Krakatoa on the other hand is more bound by hard data.
You inferred all of that from just this graph? Did know that there was another large volcanic eruption around 1809? Since the graph shows an onset of cooling around 1810, not the two decades before Mount Tambora you claim, your temporal cooling argument goes up in smoke, so to speak.
Mount Tambora was a significant eruption but it only lasted a few days. Mount Laki on the other hand erupted over an eight month period. We know how to model it because we can measure the amount of SO2 it added to the atmosphere.
Its not the length its the km^3 of volume ejected. - - - Updated - - - No the graph shows an onset of cooling in the late 17th century. Cooling does not start when you pass the mean.
the temperature sweet spot that life has evolved in is very tiny, a few degrees is significant... you need to believe in magic and deny all the laws of physics and chemistry if you think humans can't alter the environment...for every action there MUST be a reaction, and humanities contribution to the atmosphere must have an effect it's impossible for it not to...unless you believe in magic...
No you have looked at too many smoothed graphs by alarmists where they give you a 300 year average and expect you to foolishly accept that it is the same resolution as present day temperature readings. Past climate is actually quite chaotic. Even in the Holocene we see massive swings in temperature over a time span of just a few decades. While we lose resolution the further back in time we go its safe to assume that that same chaotic swings we see in the Holocene are true for all time periods.
If you only look at the volume of rock and lava ejected, then Tambora was much larger than Laki. But when you look at the amount of SO2, which is more significant to climate change, they are roughly equal. But they aren't blaming volcanos for the late 17th century cooling trend, just the sudden 1°C drops around 1783, 1810 and 1815. Before the 1800's, gradual cooling was the norm as the current interglacial leads into the next glacial period.
So instead you focus on the variability found in just one location? Sorry, but there is a reason climate is averaged over the entire globe and over 30 year periods. The temperature in one location can vary about 10 °C over the course of a day and about 30 °C over the course of the year. But when you consider that while temperatures are rising on the day side they're falling on the night side, and while one hemisphere warms during the summer while the other hemisphere cools during winter, you'll see that the average doesn't really change that much.
The oxygen isotope ratio in an ice core is representative of the temperature gradient of entire water cycle from point of evaporation to point of precipitation they are in not a regional proxy. It doesn't surprise me that you don't know the first thing about the physics of what you are talking about.
Again it doesn't surprise me that you don't know the first thing about the physics. SO2 is not a well mixed gas in the troposphere. Or have you forgotten how so many global coolest like Dr. Schneider were able to take a mulligan on global cooling. Without the eruption to push the SO2 in the stratosphere where it can mix it will not have a significant global effect. As you said Laki was a slow out-gassing over 8 months.
If ice cores are a global and not regional temperature proxy, wouldn't we see the same temperatures at both poles? Why am I not surprised that you think you know more that climate scientists. Of course the oxygen isotope ratio is dependent on evaporation and precipitation, that's what makes it such a useful proxy for temperature.
thats why they changed to climate change to cover all the bases....but i haven't checked my email today to see if there is a new name for it ...oh crap i got a blue screen..now i lost my emails.....
Don't be ridiculous.... Go to the worldwide earthquake site in real time.. Its NOT a liberal issue.. Its a geological one.
Once again, it's not me you're arguing against but rather the climate science I quote. Scientists have been studying the effect of volcanoes on climate for decades so nothing you say here is news. While Laki wasn't able to push SO2 into the stratosphere like Tambora, the extent of those emissions over 8 months allowed for more than enough mixing to significantly lower temperatures. The same effects were observed during the Mount Agung eruption from 1963 to 1964.
You should probably do some research on who was behind the supposed name change. Spoiler, it wasn't the scientists. They've been using both terms all along because they mean different things.
Both terms AT THE SAME TIME!!!! i can imagine thousands of denier brains exploding everywhere with that mind blowing concept.... sometimes I miss those past days when they blamed it on the sun, or a Al gore and Margret Thatcher socialist conspiracy to steal our money...
