Since the start of the Industrial Revolution, atmospheric CO 2 concentration have been increasing, causing global warming and ocean acidification. [12] In October 2023 the average level of CO 2 in Earth's atmosphere, adjusted for seasonal variation, was 422.17 parts per million by volume (ppm). [13]
Atmospheric carbon dioxide (CO 2) concentrations from 1958 to 2023. The Keeling Curve is a graph of the annual variation and overall accumulation of carbon dioxide in the Earth's atmosphere based on continuous measurements taken at the Mauna Loa Observatory on the island of Hawaii from 1958 to the present day.
Ocean circulation events cause this process to be variable. For example, during El Nino events there is less deep ocean upwelling, leading to lower outgassing of carbon dioxide into the atmosphere. [18] Biological processes also lead to ocean-atmosphere carbon exchange. Carbon dioxide equilibrates between the atmosphere and the ocean's surface ...
Climate 101 is a Mashable series that answers provoking and salient questions about Earth’s warming climate. The last time CO2 levels were as high as today, ocean waters drowned the lands where ...
On the current rate at which carbon dioxide and other gases are building up in the atmosphere, the world will see temperature rises well beyond 1.5C.

Topographic Map Locator map Climate change in Algeria has wide-reaching effects on the country. Algeria was not a significant contributor to climate change, [75] but, like other countries in the Middle East and North Africa (MENA) region, is expected to be among the most affected by climate change impacts.

Carbon dioxide levels have soared to 407.8 parts per million in 2018, up from 405.5 parts per million (ppm) in 2017. Carbon levels in the atmosphere ‘hit new record high’, WMO warns Skip to ...
