@ Comp.arch -- please stop adding Water Vapor to the lead -- humans do not emit water vapor in a significant way that effects climate change. The scope of the article is emissions, not greenhouse gases which includes all greenhouse gases and greenhouse effect which describes forcing and other effects, Sadads ( talk) 20:50, 17 August 2023 (UTC)
There is no reference to support the repeated assertion that more CO2 will affect the climate. And this is the basis of the whole article Bobhisey ( talk) 12:32, 17 September 2023 (UTC)
I'm planning to remove the following: "While grey hydrogen indirectly contributes to global warming, green hydrogen has the opposite effect. Green hydrogen, in the form of hydrogen fuel cells, can reduce greenhouse gas emissions from cars and trucks by replacing fossil-based fuels, such as gasoline and diesel. [1]"
Green hydrogen does not contribute to global warming but does not have an opposite effect either, i.e. it does not lead to carbon dioxide removal. Discussion about the role of hydrogen in climate change mitigation is confusing in the context of this particular section, because this section is about emissions of H2, but the role of green hydrogen is primarily to reduce the emissions of CO2.

1. I'm not sure I understand the saying - "Natural sources of carbon dioxide are nearly 20 times greater than sources due to human activity, but over periods longer than a few years natural sources are closely balanced by natural sinks, mainly photosynthesis of carbon compounds by plants and marine plankton." 2. Can anybody help use layman language to rewrite following - "Absorption of terrestrial infrared radiation by longwave absorbing gases makes Earth a less efficient emitter. Therefore, in order for Earth to emit as much energy as is absorbed, global temperatures must increase. Thank you very much. ThomasYehYeh ( talk) 01:37, 22 January 2024 (UTC)
"In October 2022, ADNOC announced to decrease the methane emissions from oil and gas by 2025." My question is "how much" ? Thank you for the kind attention. ThomasYehYeh ( talk) 05:52, 24 January 2024 (UTC)
In section ===Generational===, can anybody help elaborate the wordings "They are less affected by climate change impacts, but have e.g. the same vote-weights for the available electoral options.", especially the portion of "the same vote-weights for the available electoral options". Thanks. ThomasYehYeh ( talk) 04:56, 26 January 2024 (UTC)
(A continuation of yesterday's discussion from the Greenhouse gas talk page.)
While technically, this article's size (31 kB, 4963 words) is still only about half of the maximum recommended size (although I am fairly sure those guidelines were developed before the mass use of excerpts like in here became a thing) I think it is too large in practical terms, because the way it transitions from one topic to another seems to lack any flow and make for a confusing layout. Worse, it then often seems to double back on itself, and repeat the same or related point in slightly different terms elsewhere.
Here's what I mean:
The measurement protocol itself: This may be via direct measurement or estimation. The four main methods are the emission factor-based method, mass balance method, predictive emissions monitoring systems, and continuous emissions monitoring systems. These methods differ in accuracy, cost, and usability. Public information from space-based measurements of carbon dioxide by Climate Trace is expected to reveal individual large plants before the 2021 United Nations Climate Change Conference.(Yes, the last sentence is obsolete now.) How many readers are really here for "time horizons" and "national account balances"? About 90% of this seems to belong in greenhouse gas monitoring and greenhouse gas inventory (ideally, we could probably purge a lot of the excessive, possibly plagiarized detail from the latter and merge it into the former, but that would take a while). This article should only have the briefest summary, and it likely belongs around the very end.
Fossil fuels (32%), again, account for most of the methane emissions including coal mining (12% of methane total), gas distribution and leakages (11%) as well as gas venting in oil production (9%).
Livestock (28%) with cattle (21%) as the dominant source, followed by buffalo (3%), sheep (2%), and goats (1.5%).
Human waste and wastewater (21%): When biomass waste in landfills and organic substances in domestic and industrial wastewater is decomposed by bacteria in anaerobic conditions, substantial amounts of methane are generated.
Rice cultivation (10%) on flooded rice fields is another agricultural source, where anaerobic decomposition of organic material produces methane.
Or indeed, basically everything in Human activities can be rewritten to go sector by sector:
The main sources of greenhouse gases due to human activity (also called carbon sources) are:
Burning fossil fuels: Burning oil, coal and gas is estimated to have emitted 37.4 billion tonnes of CO2eq in 2023. The largest single source is coal-fired power stations, with 20% of greenhouse gases (GHG) as of 2021.
Land use change (mainly deforestation in the tropics) accounts for about a quarter of total anthropogenic GHG emissions.
Livestock enteric fermentation and manure management, paddy rice farming, land use and wetland changes, man-made lakes, pipeline losses, and covered vented landfill emissions leading to higher methane
atmospheric concentrations. Many of the newer style fully vented septic systems that enhance and target the fermentation process also are sources of atmospheric methane.
Use of chlorofluorocarbons (CFCs) in refrigeration systems, and use of CFCs and halons in fire suppression systems and manufacturing processes.
Agricultural soils emit nitrous oxide (N2O) partly due to application of fertilizers.
The largest source of anthropogenic methane emissions is agriculture, closely followed by gas venting and fugitive emissions from the fossil-fuel industry. The largest agricultural methane source is livestock. Cattle (raised for both beef and milk, as well as for inedible outputs like manure and draft power) are the animal species responsible for the most emissions, representing about 65% of the livestock sector's emissions.

Hello @ RCraig09
The interesting chart at the beginning of this article seems to have contradictory captions. The one below says ‘greenhouse gas’ and the one at the top actually in the chart says ‘carbon dioxide’. Chidgk1 ( talk) 15:20, 8 April 2024 (UTC)
I've just removed this recently added text block. I am putting it below because certain statements might be salvageable but overall it reads like UN speech, not encyclopedic language. It also introduces repetition. Also, the exact source is not clear, please provide page numbers, User:BaderMS.
I've noticed that you (User:BaderMS) have recently added content in a similar fashion to a range of Wikipedia articles (I have reverted some of those additions). You seem to add one big long paragraph full of jargon and UN-type speech, with just one vague reference at the end (never with page numbers). Those paragraphs that I reverted were not written in encyclopedic and summary style. Please reconsider how you add content. It might be better to edit in small incremental steps, i.e. just a sentence or two at first, not those long paragraphs with just one ref at the end. Also ensure not to add excessive detail to high level articles, like you did at energy transition where you added detailed content (from a low quality source) on electric vehicles in China.
Here is the text block that I've removed:

In November 2023, the UNEP published the Emissions Gap Report 2023, signaling an alarming escalation in global greenhouse gas emissions that have led to a dramatic rise in extreme weather events and grave climate consequences. The progress since the Paris Agreement is noted, with a revised estimate that emissions in 2030 are expected to be 3% above 2010 levels rather than the previously anticipated 16%. However, the current trajectory is still on a collision course with a temperature increase that will likely surpass the Paris Agreement's targets. The report projects a potential global temperature rise of up to 2.9°C by the end of this century. UNEP's findings serve as a clarion call for nations, particularly the most capable and historically largest emitters, to urgently strengthen their emission reduction commitments to mitigate the risk of catastrophic climate effects.
