Great parts of North Africa and Southern Africa as well as the whole Horn of Africa mainly have a hot desert climate, or a hot semi-arid climate for the wetter locations. The Sahara Desert in North Africa is the largest hot desert in the world and is one of the hottest, driest and sunniest places on Earth.
Energy in Africa is a scarcer commodity than in the developed world – annual consumption is 518 KWh in Sub-Saharan Africa, the same amount of electricity used by an individual in an Organization for Economic Cooperation and Development (OECD – example is the U.S.) country in 25 days. [12] More than 500 million people live without electricity.
Green house gases being emitted from a chimney in a natural gas and oil field in Western Iran. As of January 2021, the UNICEF website groups the following set of 20 countries as belonging to the MENA region: 'Algeria, Bahrain, Djibouti, Egypt, Iran (Islamic Republic of), Iraq, Jordan, Kuwait, Lebanon, Libya, Morocco, Oman, Qatar, Saudi Arabia, State of Palestine, Sudan, Syrian Arab Republic ...
Global human-caused greenhouse gas emissions in 2019 were equivalent to 59 billion tonnes of CO 2. Of these emissions, 75% was CO 2, 18% was methane, 4% was nitrous oxide, and 2% was fluorinated gases. [111] CO 2 emissions primarily come from burning fossil fuels to provide energy for transport, manufacturing, heating, and electricity. [5]
For a doubling of greenhouse gas concentrations, the global mean temperature would rise by about 2.5–4 °C (4.5–7.2 °F). [28] If emissions of CO 2 stopped abruptly and there was no use of negative emission technologies, the Earth's climate would not start moving back to its pre-industrial state. Temperatures would stay at the same high ...
Carbon dioxide is the main greenhouse gas resulting from human activities. It accounts for more than half of warming. Methane (CH 4) emissions have almost the same short-term impact. [5] Nitrous oxide (N 2 O) and fluorinated gases (F-gases) play a lesser role in comparison. Emissions of carbon dioxide, methane and nitrous oxide in 2023 were all ...
Contrary to what is sometimes said, greenhouse gases do not "re-emit" photons after they are absorbed. Because each molecule experiences billions of collisions per second, any energy a greenhouse gas molecule receives by absorbing a photon will be redistributed to other molecules before there is a chance for a new photon to be emitted.

Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...
