Yes well, we won't get pedantic on every square inch to km that is uninhabited.
Unless they have well measured out recording beacons in every square km?
Then I guess we just go by with what we got.
Not happy - go fund a better version.  Cheesy

It won't be till tomorrow night before I get my answer.



You do realise the error bars in homogenisation of that size? Wink

Question.
If we just had the highest CO2 levels in 800,000 years doesn't that mean we've had higher before then? Grin

It's about rates of change!

Should we have another ten billion page circle jerk about rates of change because I know you want to?

We should be getting more concerned about N20 and CH4.   N20 is up to 300 times more effective at trapping heat in the atmosphere.

Carbon dioxide is the currency of climate change and, in those terms, one tonne of methane emitted to the atmosphere (for example from livestock) is equivalent to 34 tonnes of carbon dioxide emissions. One tonne of nitrous oxide is equivalent to 298 tonnes of carbon dioxide.

They talk about CO2e for a reason and they always have....

Sorry - didn't get my answer from the Antarctic.
Was 'busy' watching Ragnarok.  Cheesy
Maybe tomorrow night.

But I will add that yes - Methane is the biggest worry and with all the Permafrost areas of Canada/Siberia releasing 'accelerating' amounts and amounts also up from the oceans...

Yes we have. But since homo sapiens have only been around for 200,000 years it's completely irrelevant

And yet -

"The last ice age transition to a warmer climate some 11,500 years ago did not include massive methane flux from marine sediments or the tundra, new research suggests. Instead, the likely source of rising levels of atmospheric methane was from tropical wetlands, authors of the new study say. "

"Atmospheric methane has increased from 750 parts per billion in the year 1750 to more than 1,800 parts per billion today -- mostly from anthropogenic sources, especially leakage from fossil fuel production, the creation of rice paddies, and cattle ranching, the researchers say."

From the same article

While this certainly is good news, the study also points at a larger role of humans in the recent methane rise, noted Edward Brook, an Oregon State University paleoclimatologist and co-author on the study

"Our findings show that natural geologic emissions of methane -- for example, leakage from oil seeps or gas deposits in the ground -- are much smaller than previously thought," Brook said. "That means that a greater percentage of the methane in the atmosphere today is due to human activities, including oil drilling, and the extraction and transport of natural gas."

The study suggests that human emissions of geologic methane may be as much as 25 percent higher than previous estimates. Although not as abundant as carbon dioxide, methane is a much more powerful greenhouse gas and therefore the rising levels are an important contributor to global warming.

So lee, do you agree with this part of the study too? Or do you just cherry pick the parts of the study that suit you?

Of course I agree it is part of the study.

Now all they have to do is prove they have identified all the methane seeps in the ocean. Wink

So you disagree with the inconvenient parts

Good to see that you are consistently inconsistent  Roll Eyes

So you agree wholeheartedly with anything that may have one tiny part that you think true?

"Scientists have shown that ocean clams and worms are releasing a significant amount of potentially harmful greenhouse gas into the atmosphere.

The team, from Cardiff University and Stockholm University, have shown that the ocean critters are producing large amounts of the strongest greenhouse gases - methane and nitrous oxides - from the bacteria in their guts.

Methane gas is making its way into the water and then finally out into the atmosphere, contributing to global warming - methane has 28 times greater warming potential than carbon dioxide.

A detailed analysis showed that around 10 per cent of total methane emissions from the Baltic Sea may be due to clams and worms."

"Co-author of the study Dr Ernest Chi Fru, from Cardiff University's School of Earth and Ocean Sciences, said: "What is puzzling is that the Baltic Sea makes up only about 0.1% of Earth's oceans, implying that globally, apparently harmless bivalve animals at the bottom of the world's oceans may in fact be contributing ridiculous amounts of greenhouse gases to the atmosphere that is unaccounted for."

And that's just from the clams and worms. The other 90%?
