How is the CO2 data for the Keeling Curve collected and processed? What was a significant recent milestone for the Keeling Curve, as highlighted in their videos? Where can I find information on other climate indicators besides CO2 or carbon emissions, and what are two examples of such external resources they link to?
Navigate to the 'FAQs' page. Click on the article 'How are CO2 Data Processed?'. Read the article to understand the data processing methodology. Navigate to the 'Videos' page. Identify a key recent milestone mentioned in a video description. Navigate to the 'Other Climate Indicators' page. Identify two external resources that provide data on phenomena other than atmospheric CO2 or carbon emissions.
Explain that CO2 data is collected in remote locations (e.g., Mauna Loa) to avoid local influences and ensure representativeness, with continuous measurements and filtering of anomalous readings. State that a significant recent milestone was the Keeling Curve hitting 420 PPM in 2021. Confirm that the 'Other Climate Indicators' page provides information on other climate indicators. List two external resources from the 'Other Climate Indicators' page that are not focused on atmospheric CO2 or carbon emissions (e.g., NOAA Sea Level Rise Viewer, Greenland Ice Sheet Today, Argo).
