Reply to James Asherman three many years ago Climate scientist James Hansen has advised that we should seek to limit CO2 to 350ppm, Whilst for Many many years, pure cycles didn’t provide it higher than 300ppm:
2 many years ago The post discusses why water inside the atmosphere isn't answerable for world wide warming. I'm considering your thoughts on the opposite question: could rising the amount of drinking water during the environment interesting the Earth?
While most h2o drops out of your atmosphere as rain there remains to be major volumes of water in air across the globe where by the temperature is previously mentioned the dew issue.
Reply to Zagzigger 3 yrs ago Neither John Kerry or any person else is suggesting that we remove all CO2 with the ambiance (which happens to be neither probable or desirable). If you study the quotation above cautiously you'll Be aware it suggests “Web zero”, which implies getting to The purpose wherever our CO2 emmissions are no longer raising the CO2 focus within the environment.
Reply to Chase two many years back Yes, but it really reflects back again much more infrared than it does noticeable mild. Hence the noticeable light-weight can reach the earth and turn to heat. Portion of the heat which would previously escape as infrared has become trapped.
But as soon as the tube is filled with carbon dioxide, the infrared graphic on the flame disappears, since the CO2 during the tube absorbs and scatters the warmth from your candle in all directions, and therefore blurs out the picture on the candle. There are several video clips with the experiment on line, including this one:
Keeping up with the most recent weather rules is difficult. So Permit’s make it easy. Check out the table below from our most recent book: The 2024 Guideline to U.
Reply to Barton Paul Levenson two yrs back . . . it doesn’t replicate to the bottom whatsoever. Just about the entire terrestrial IR is captured by CO2. For the same motive, practically each of the terrestrial IR which can be absorbed by CO2 is absorbed in just 15m of the bottom.
The map displays significant inequalities of contribution the world over. The United states has emitted by far the most thus far: close to a quarter of all historic CO2: 2 times that of China which can be the next most significant contributor.
There's also corporations that assist to establish companies and score them for ESG (Environmental, Social, and Governance) or socially dependable buyers like Sustainalytics or MSCI. Every investor, firm, and government need to choose for by themselves what matches their plans. This is where the need for metrics and standardization results in being essential.
Reply to Raafter 2 many years back As talked about over, visible gentle coming with the sun passes the CO2 molecules without interaction. On achieving the ground several of the obvious gentle is re-radiated from the bottom as infra-crimson radiation, which does interact with CO2.
two years in the past The runaway Greenhouse impact on Venus just isn't authentic. It goes as follows: In the cosmic bombardment; in the event the planets were being molten rock, Venus and Earth gained water through millions of meteorites which were continually crashing in to the planets. On Venus, being Significantly closer to your Sunlight, h2o never ever obtained the chance to condensate to h2o. So each of the h2o obtained, crafted up as vapor from the beginning. The stress saved escalating whilst it obtained additional water right until the level we see nowadays. It never got a chance to sort oceans and rivers.

All I’m saying is the aircraft fact that if any person is concerned about reducing anthropogenic global warming consequences, the very best method is to test to reduce waste heat.
