Research into this topic is fairly new, with very few studies published before 2009, but has gained increasing attention in recent years. The majority of studies show that a global transition to 100% renewable energy across all sectors – power, heat, transport and industry – is feasible and economically viable.
Not sure what you’re basing this grand assertion that most studies show the transition is feasible and economically viable. For every study that shows this, I can find you one that shows the opposite. In fact, as you admit, this is a new research topic with a lot of unknowns, and we are in a middle of a global crisis that threatens our whole civilization. Using proven technologies that are known to work seems like a far better thing to do than to experiment in a middle of a crisis.
That’s a valid point. There is no consensus yet. But what’s the worst that would happen if we can’t achieved this goal in Germany, when we try? We will buy french nuclear power again. But what happens when it works out? Germany will be climate neutral and will be independent of nuclear power. No fission material is required, no uranium mining will be required for power production. So there’s the possibility to mitigate the negative impact of uranium mining, while getting rid of the dangers of nuclear power plants and not creating more nuclear waste for future generations to take care of. IMHO that’s a great opportunity that we should seize.
The worst that will happen is that our civilization collapses because we failed to transition away from the use of fossil fuels. Buying energy from France is the best case scenario, using more coal and other dirty fuels if the transition fails is another very likely scenario. And once again, I’ll note that there are alternatives to uranium such as thorium. The only reason uranium is used traditionally is because it doubles up as weapons material. Thorium reactors are cheaper, safer, and don’t require water cooling. Why not explore all options, and find a mix of solutions that work reliably. In a situation where there are many unknowns, it’s generally best not to put all the eggs in one basket.
Fossil fuel is IMHO no alternative and will only play a minimal role after 2038. Most of the countries, that have pledged to become climate neutral by 2050 will build new nuclear reactors to achieve this. So there will probably be enough energy to go around and Germany can buy such energy if the transition to 100% renewables did not work out as planned. But if it works out we will have a viable way to produce energy in climate neutral way without the hazards that accompany nuclear power production. If this can be proved to work, other countries would be able to emulate this strategy. IMHO this is an opportunity we can not let go to waste.
Every technology has pros and cons. The rational thing to do is to weigh those against each other instead of simply pointing out what the negatives are. Meanwhile, there are also CO2 emissions involved in producing solar panels or wind turbines.
The reality is that majority of western countries continue to miss their pledges to transition from fossil fuels. Given past precedent, I would bet against Germany accomplishing its stated goals by 2038. IMHO gambling with the fate of humanity for ideological reasons is unethical.

Hers an interesting article on the dangers of Thorium reactors, including nuclear proliferation concerns: https://www.nature.com/articles/492031a
Here’s an article detailing why nuclear power production is not climate neutral. There a lot of CO2 emissions involved in nuclear power production: https://www.dw.com/en/fact-check-is-nuclear-energy-good-for-the-climate/a-59853315
