Climate change mitigation policies can have a large and complex impact on the socio-economic status of individuals and countries This can be both positive and negative. [299] It is important to design policies well and make them inclusive. Otherwise climate change mitigation measures can impose higher financial costs on poor households. [300]
Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
International Earth Day, celebrated annually on April 22, presents an excellent opportunity to assess the state of the planet. The year 2023 was recorded as the hottest year on record.
Their findings include several factors, and allow for natural climate change as well as man-made carbon dioxide emissions. A graph shows that up until around 1970, the variance in Earth's temperatures was largely due to inherent anomalies, but from then on there is a marked escalation, which can only be explained by human activity.
Yes, as Mann states, “climate change is a crisis, but a solvable crisis.” While Earth was created about 4.5 billion years ago, science has reported five mass extinctions during the past 50 ...
The dangers of climate change aren’t an excuse to take dangerous risks “Just because we’re desperate doesn’t suddenly make solar geoengineering a good idea, because the risks are so ...
A 2023 review study published in One Earth stated that opinion polls show that most people perceive climate change as occurring now and close by. [175] The study concluded that seeing climate change as more distant does not necessarily result in less climate action, and reducing psychological distancing does not reliably increase climate action ...
Climate engineering (or geoengineering, climate intervention [1]) is the intentional large-scale alteration of the planetary environment to counteract anthropogenic climate change. [ 2 ] [ 3 ] The term has been used as an umbrella term for both carbon dioxide removal and solar radiation modification when applied at a planetary scale.
