Effects of Climate Change (Semper Idem)

The effects of climate change are the environmental, social, and economic changes caused by human altering of the natural ecosystem, including emissions through greenhouse gases. These effects included the shutdown of thermohaline circulation, glacial retreat, flooding, changes in agricultural productivity, the extinction of animal and plant species, among other things. The Anthropocene Climate Change is generally agreed to have started in 1975, with most environmental and social changes occurring from the 2040s-2050s. The United Nations Climate Commission declared in 2039 that the world climate is changing in two phases, the first phase from 1975-2029 were mostly small effects on weather patterns and natural events, while the second and current phase results in deadlier and more more pronounced effects, such as sea level rise, temperature changes, and heavy effects on social and economic systems.

Effects on climate change depended on region.

Prevention of Climate Change
Since the slow event of global warming and eventually climate change was discovered in the 1970s, there have been many attempts to stop, reverse, and eventually mitigate the effects of climate change.

The Mitigation Agreement, a policy enacted by most members of the United Nations in 2036, mostly focused on adapting to the impacts of climate change, while previous agreements such as the Paris Agreement and Montreal Protocol focused on stopping the problem at hand. This represented a shift of tone in climate change policy, as instead of stopping it, policymakers realized that the best way to deal with the problem was to adapt to it.

One of the main problems in combating climate change was the Haux Problem, which stated that climate change, as well as most problems of the 21st century, required international cooperation to effectively solve the problem. However, during the early 21st century, some lawmakers were unwilling to stifle economic growth to reduce carbon emissions, until climate change itself started stifling economic growth.

The first and most successful international agreement on stopping effects of human caused climate change was the Montreal Protocol in 1987, banning the use of certain harmful chemicals, helping regenerate the ozone layer and prevent ozone depletion.
