What was the CO2 level in 2015?
401.01
In 2021, atmospheric carbon dioxide levels reached a high of 416.45 parts per million, in comparison to 1960 levels which stood at about 316.91 parts per million….
| Characteristic | Concentration in parts per million |
|---|---|
| 2016 | 404.41 |
| 2015 | 401.01 |
| 2014 | 398.87 |
| 2013 | 396.74 |
Why is the carbon dioxide level lower in September of each year?
When plants are growing, photosynthesis outweighs respiration. As a result, plants take more CO2 out of the atmosphere during the warm months when they are growing the most. This can lead to noticeably lower CO2 concentrations in the atmosphere.
Which country produced the most CO2 in 2015?
China
China is the world’s largest contributor to CO2 emissions—a trend that has steadily risen over the years. The country now produces 9.9 billion metric tons of CO2.
What is the current carbon dioxide level?
Based on preliminary analysis, the global average atmospheric carbon dioxide in 2020 was 412.5 parts per million (ppm for short), setting a new record high amount despite the economic slowdown due to the COVID-19 pandemic.
What was the average CO2 concentration last year?
419.41 ppm

| 1 Year Change | 0.63 ppm (0.15%) |
What is happening to CO2 levels year to year?
First, the annual average CO2 concentration is increasing year-on-year. This is mainly due to the burning of fossil fuels, with further contributions from deforestation. Second, as human-driven emissions have increased, the rise in CO2 has accelerated. It took over 200 years to reach a 25% increase by 1986.
What happens to CO2 levels in the winter months?
Then at night or during autumn and winter, plants reduce or even stop photosynthesising, releasing carbon dioxide back into the air. This is often called the natural carbon cycle.
How much CO2 is emitted each year?
about 43 billion tons
Tons of CO2 emitted into the atmosphere The world emits about 43 billion tons of CO2 a year (2019). Total carbon emissions from all human activities, including agriculture and land use.
What was the CO2 level in 2015 2015?
2015 Begins With CO2 Above 400 PPM Mark. The new year has only just begun, but we’ve already recorded our first days with average carbon dioxide levels above 400 parts per million, potentially leading to many months in a row above this threshold, experts say. when they jumped above 400 ppm.
When was the last time the CO2 levels were so high?
In fact, the last time the atmospheric CO₂ amounts were this high was more than 3 million years ago, when temperature was 2°–3°C (3.6°–5.4°F) higher than during the pre-industrial era, and sea level was 15–25 meters (50–80 feet) higher than today.
What’s new with carbon dioxide levels?
What’s New? The global average atmospheric carbon dioxide in 2019 was 409.8 parts per million ( ppm for short), with a range of uncertainty of plus or minus 0.1 ppm. Carbon dioxide levels today are higher than at any point in at least the past 800,000 years.
What is the modern record of atmospheric carbon dioxide levels?
The modern record of atmospheric carbon dioxide levels began with observations recorded at Mauna Loa Observatory in Hawaii. This graph shows the station’s monthly average carbon dioxide measurements since 1960 in parts per million (ppm).
