Climate change in Algeria has wide-reaching effects on the country. Algeria was not a significant contributor to climate change,[1] 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.[2] Because a large part of the country is in already hot and arid geographies, including part of the Sahara, already strong heat and water resource access challenges are expected to get worse.[1] As early as 2014, scientists were attributing extreme heat waves to climate change in Algeria.[1] Algeria was ranked 46th of countries in the 2020 Climate Change Performance Index.[3]
