9 Αυγ 2021 · Changes to the ocean, including warming, more frequent marine heatwaves, ocean acidification, and reduced oxygen levels have been clearly linked to human influence. These changes affect both ocean ecosystems and the people that rely on them, and they will continue throughout at least the rest of this century.

- Global Warming of 1.5 C
2 Οκτ 2019 · Our atmosphere seems tantalizingly close and yet mysteriously distant. The life-sustaining air we breathe envelops our planet like a pale-blue security blanket, clinging to us by the force of gravity. We see birds, planes, an ever-changing patchwork of clouds and, in some places, air pollution.
The atmosphere is vital for all life on the planet, not only humans, and for reasons other than supplying gases needed for respiration and photosynthesis. Winds also transport water into the interiors of large areas of land, which would otherwise rapidly become parched desert.
Earth’s atmosphere does many important tasks for us—it shields us from UV radiation, generates weather, and is the very air we breathe. But its ability to keep our planet warm is what makes the atmosphere so important to climate change.
18 Μαΐ 2021 · Atmospheric CO 2 levels of between 280 and 350 parts per million created the climate that let humanity build and feed the modern world. The farther we get from those levels, the more we run the risk of disturbing that balance.
21 Φεβ 2022 · In this article, we will explore how we know that the climate has changed so quickly in the last century, what carbon dioxide (CO2) has to do with climate change, and why humans are responsible for the recent increase of CO2 in the atmosphere.
Scientists have determined that carbon dioxide plays a crucial role in maintaining the stability of Earth's atmosphere. If carbon dioxide were removed, the terrestrial greenhouse effect would collapse, and Earth's surface temperature would drop significantly, by approximately 33°C (59°F).
