The Gateway Belief Model, which models the thought that communicating scientific consensus will impact belief in climate change and produce support for action. Most climate communication and research within the field is concerned with (1) the mechanisms related to the public's understanding/awareness of and perception of climate change which are intertwined with (2) personal cultural values ...
These numbers show that awareness of global warming was increasing in the United States. [306] A Gallup poll showed that 62% of Americans believe that the effects of global warming were happening in 2017. [307] In 2019, Gallup poll found that one-third of Americans blame unusual winter temperatures on climate change. [308]
Increased rainfall and the melting of ice due to global warming dilutes the salty surface water, and warming further decreases its density. The lighter water is less able to sink, slowing down the circulation. [13] Theory, simplified models, and reconstructions of abrupt changes in the past suggest the AMOC has a tipping point.
Due to its high climate variability and rainfed agriculture, Central Africa is expected to experience longer and more frequent heatwaves as well as an increase in wet extremes. [84] The global mean temperature in this region is to increase by 1.5 °C to 2 °C. [85] The carbon dioxide-absorbing capacity of forests in the Congo Basin have ...
As of 2021, based on information from 48 national climate plans, which represent 40% of the parties to the Paris Agreement, estimated total greenhouse gas emissions will be 0.5% lower compared to 2010 levels, below the 45% or 25% reduction goals to limit global warming to 1.5 °C or 2 °C, respectively.
[32] [33]: 1057 In some tropical and subtropical regions of the world, there will probably be less rain due to global warming. This will make them more prone to drought. Droughts are set to worsen in many regions of the world. These include Central America, the Amazon and south-western South America. They also include West and Southern Africa.
According to a 2015 journal article based on a literature review of thousands of articles related to over two hundred studies covering the period from 1980 to 2014, there was an increase in public awareness of climate change in the 1980s and early 1990s, followed by a period of growing concern— mixed with the rise of conflicting positions—in the later 1990s and early 2000s.
As a result, the country drew the admiration of many newly independent states in Africa. The adoption of the Ethiopian national colours by many Pan-African entities is a consequence of this. The first African state to adopt a gold, red and green flag upon independence was Ghana in 1957, designed by Theodosia Okoh .
