Reply to James Asherman 3 yrs back Climate scientist James Hansen has suggested that we should attempt to Restrict CO2 to 350ppm, Despite the fact that for Countless a long time, organic cycles didn’t convey it higher than 300ppm:
Can you tackle A further query I've concerning the IR heat trapping capabilities of atmospheric CO2. I've an exceedingly impression oriented thoughts and here is the graphic I conjure up regarding the phenomenon.
In this article We have now grouped the countries in the eu Union given that they commonly negotiate and established targets like a collective entire body. You are able to see the information for personal EU nations from the interactive maps that observe.
Reply to James Asherman three decades back The CO2 scatters the infrared by absorbing it and reemitting in all Instructions — which happens to be what exactly the movie claims to point out. Given that many of the infrared is bounced again to your resource, it is frequently characterized as “blocking.”
In the case of greenhouse gases, the Earth’s temperature is really a equilibrium concerning just how much Power is available in compared to the amount of Vitality goes out.
This was basically the the very least contentious response. I was just pondering how everyone at Columbia would reply these counter-arguments.
Reply to John Sheppard two several years in the past There’s no fantastic back again up. The moment, it was CFC depleting ozone layer. Today, it’s CO2 blanketing the atmosphere. The nice concept would be that the entropy of the universe raises but never ever decreases.
At some time CO2 does its career of catching a sky traveling photon only to re-emit it at One more random stable angle. Presumably 50 % of these photons will arise while in the hemisphere headed back again towards the strong Earth, one other 50 % will continue Lease on in a few random skybound way. To my simple technique for imagining The online result of these interactions is zero
burned domestically, we for that reason must suitable for this trade. If we consider its domestic production (account for just about any fuel it shops as shares), incorporate any fuel it imported, and subtract any gasoline it exported, We now have an estimate of its Web use in 1900.
The obvious retort Here's a large number of actions necessary if mainstream theories are appropriate sound right whatever the character, extent, bring about and direction if weather modify. They might assistance cope which has a volcanic Winter season (e.g. that in 1816 once the Tambora eruption) and likewise the collapse of A significant meals crop. Illustrations consist of less squander, combining conservation with watchful use, restoring fish shares, increasing much less money crops, regenerative agriculture, silviculture and reducing the impression for every head and probably quantities of traditional livestock.
And Sure, extra CO2 has less of an result effect from the Troposphere. The average escape height for quanta to outer Room can only go so significant, pretty a posh density v emmissivity calc? The top in the Troposhere is 10 – 15km
But by burning these fossil fuels, human beings are including a lot additional carbon in to the environment and ocean, and also the carbon sinks don’t get the job done rapidly sufficient to wash up our mess.
Carbon dioxide emissions are the primary driver of worldwide weather improve. It can be broadly regarded that to avoid the worst impacts of weather alter, the whole world should urgently decrease emissions.
The stated greenhouse impact of CO2 is not in accordance Along with the molecular Qualities of CO2. These ought to be handled quantum mechanically. The conversation with radiation as well as intermolecular interactions are described by quantum mechanics.
