Stretch ... just out of curiosity, if there are 1000 scientists whose career is studykng global warming, the cause and effect, and also man's participation, are they split like 55/45 that man's participation has a big impact vs those who believe this is a course of nature. Is the data pretty split on eaxh side of the discussion ?
It’s hard:
Here's a comparison of total carbon output for the top 10 carbon-emitting countries, along with an indication of whether their carbon output has been increasing or decreasing based on recent data:
### Top 10 Carbon Emitting Countries by Total Carbon Output:
1. **China**:
- **Total Emissions**: Approximately 11-12.6 Gt CO₂ per year.
- **Trend**: **Increasing**. Despite pledges for cleaner energy, China's emissions have been on an upward trajectory, with industrial and power generation activities being major contributors. However, recent years have shown some stabilization or slight decrease due to policy changes and renewable energy investments.[](https://worldpopulationreview.com/country-rankings/carbon-footprint-by-country)[](https://www.visualcapitalist.com/carbon-emissions-by-country-2022/)[](https://edgar.jrc.ec.europa.eu/report_2022)
2. **United States**:
- **Total Emissions**: Roughly 4.5-5.1 Gt CO₂ per year.
- **Trend**: **Decreasing**. The U.S. has experienced a reduction in emissions, thanks to a shift towards natural gas, renewable energy, and efficiency improvements, although there have been fluctuations.[](https://worldpopulationreview.com/country-rankings/carbon-footprint-by-country)[](https://www.iea.org/reports/co2-emissions-in-2022)
3. **India**:
- **Total Emissions**: About 2.7-3.1 Gt CO₂ per year.
- **Trend**: **Increasing**. India's emissions are growing due to rapid industrial growth, urbanization, and increased energy demand, predominantly from coal.[](https://worldpopulationreview.com/country-rankings/carbon-footprint-by-country)[](https://www.visualcapitalist.com/carbon-emissions-by-country-2022/)[](https://edgar.jrc.ec.europa.eu/report_2022)
4. **Russia**:
- **Total Emissions**: Approximately 1.7-2.2 Gt CO₂ per year.
- **Trend**: **Slightly Increasing**. While there have been fluctuations, overall emissions have seen a slight increase, with energy production being a significant factor.[](https://worldpopulationreview.com/country-rankings/carbon-footprint-by-country)[](https://edgar.jrc.ec.europa.eu/report_2022)
5. **Japan**:
- **Total Emissions**: Around 1-1.1 Gt CO₂ per year.
- **Trend**: **Stable to Decreasing**. Japan has had a relatively stable output, with some decreases attributed to energy efficiency and a shift towards renewables, though there are challenges due to nuclear energy phase-out.[](https://worldpopulationreview.com/country-rankings/carbon-footprint-by-country)[](https://edgar.jrc.ec.europa.eu/report_2022)
6. **Indonesia**:
- **Total Emissions**: About 0.7-0.9 Gt CO₂ per year.
- **Trend**: **Increasing**. With deforestation and coal power expansion, Indonesia's emissions have been on an upward trend.[](https://worldpopulationreview.com/country-rankings/carbon-footprint-by-country)[](https://www.visualcapitalist.com/carbon-emissions-by-country-2022/)
7. **Iran**:
- **Total Emissions**: Roughly 0.7-0.9 Gt CO₂ per year.
- **Trend**: **Increasing**. Due to oil and gas production, Iran's emissions have been increasing, though economic sanctions might influence this.[](https://worldpopulationreview.com/country-rankings/carbon-footprint-by-country)[](https://www.visualcapitalist.com/carbon-emissions-by-country-2022/)
8. **Germany**:
- **Total Emissions**: Approximately 0.6-0.7 Gt CO₂ per year.
- **Trend**: **Decreasing**. Germany has been reducing emissions through coal phase-out and increasing renewable energy use, though the pace has varied.[](https://worldpopulationreview.com/country-rankings/carbon-footprint-by-country)[](https://edgar.jrc.ec.europa.eu/report_2022)
9. **South Korea**:
- **Total Emissions**: Around 0.6-0.7 Gt CO₂ per year.
- **Trend**: **Increasing**. With industrial growth and reliance on coal and gas for energy, emissions are generally increasing.[](https://worldpopulationreview.com/country-rankings/carbon-footprint-by-country)[](https://www.visualcapitalist.com/carbon-emissions-by-country-2022/)
10. **Saudi Arabia**:
- **Total Emissions**: About 0.6-0.7 Gt CO₂ per year.
- **Trend**: **Stable to Increasing**. Given its role in oil production, emissions are significant and have been stable or slightly increasing.[](https://worldpopulationreview.com/country-rankings/carbon-footprint-by-country)[](https://www.visualcapitalist.com/carbon-emissions-by-country-2022/)
**Notes:**
- The trends are based on recent data and general patterns but can change with new policies, economic conditions, or technological advancements.
- The emissions data provided are from sources like the International Energy Agency (IEA), various web resources, and posts on X, which might have slight variations year by year or due to different methodologies in calculating emissions.
- These trends can be influenced by short-term factors like economic downturns, policy changes, or global events such as pandemics, which can cause temporary decreases in emissions.
