A model of Global Climate Change driven by the impact of Carbon Dioxide on the Greenhouse Effect. This model contains a physical model of energy inflows ☀️ and outflows from the Earth (primary source). And a simple model of carbon dioxide sources and sinks in the atmosphere (primary source).

The energy model assumes inflowing short-wave solar radiation that does not interact with the atmosphere. A fraction of this is reflected immediately (e.g. by snow and ice cover). The remaining is absorbed 🌎 and re-radiated as long-wave infrared which can be captured by the atmosphere ☁️. The fraction captured by the atmosphere is related to the level of Carbon Dioxide in the atmosphere.

This model tracks Carbon Dioxide emissions from burning fossil fuels 🏭 and land use changes 🚜 (e.g. deforestation). It also tracks removal of Carbon Dioxide from the atmosphere into a land sink 🌲 (e.g. vegetation) and the an ocean sink 🏖.

🧪 Experiment with different levels of emissions to see their impact on global average temperatures. You can also compare predicted temperatures and Carbon Dioxide levels to historical data.

Climate Politics Neoliberlaism
In fairness it is not just the Republican Party that believes in Neoliberalism, but it seems to adhere to the most puritan form of it. The principal tenets of Neoliberalism, free and unfettered markets and tight fiscal control are diametrically opposed to what is needed to fight climate change and its effects. Such policies involve massive fiscal spending and government investment in new infrastructure and renewable energy.  They  also involve wide ranging regulation of the private sector,  especially restrictions on the fossil fuel industry. Accepting the reality of man-made climate change and the policies needed to counter it really amounts to admitting that Neoliberalism has failed. The CLD tries to illustrate the self-reinforcing dynamic that may have led the leaders of the Republican Party to deny climate change. Of course, there are also other factors involved, such as party loyalty, internal pressure to conform, cognitive dissonance and probably many more. Please also have a look at Insight 66858 which is related to this subject.

As general population is composed of 85% with an education level of a 12 grader or less (a 17 year old), a simple block of components concerning the health of the planet needs to be broken down into simple blocks.
Perhaps this picture will show the basics on which to vote for a sustained healthy future
Democracy is only as good as the ability of the voters to FULLY understand the implications of the policies on which they vote., both context and the various perspectives.   National voting of unqualified voters on specific policy issues is the sign of corrupt manipulation.
