    Absolutely understandable. Maybe there is some easy tool around, but I see some potential problems.

    Questions such as “Is this zone habitable in 2035” or “Will this area be ocean in 2050” are extremely hard to answer with our current knowledge and available data. As you probably know, climate scientists speak of probabilities, as projections e.g.for temperature are highly uncertain, especially in the more far away future. If there is a tool answering such questions, you probably can’t trust it. Then, you will likely not get a one does it all tool, as the questions OP asked are highly specific. All in all the matter is very complex and there are no easy answer. You need some kind of motivation to gather a certain amount of background knowledge about the topic.

    I think what comes closest to what OP wants is downloading model results from largely accepted climate models such as CMIP6. They usually come in special file formats that can efficiently store geospatial time series, such as netCDF or HDF5. There are tools like Panoply where you can do some very nice visualisations. You do not need to code neither is the software very complex. QGIS and ArcGIS are overkill here, as you would not want to do spatial analysis but only visualize.

    The work you would need to do is 1) understanding what you want - there is not a single result, instead you have climate projections under several different scenarios, model assumptions, input data etc. You need to figure out what to choose. 2) Have a decent feeling of geospatial visualization techniques. Cartography is a complex field, and correctly visualizing data is pretty hard.

    I am sorry I cannot provide easy solution. WhatI can offer is helping to acquire data if you what you want and also I can give technical support on visualization software. Maybe also give you some guidelines on how to interpret a figure.

    A small add-on:

    Usually, plants get most their nutrients from the soil, most importantly nitrogen (but also P, K and some others).

    In some locations, such as swamps or very sandy soils, there is not a lot of nutrients for the plants to get and these “nutrient-poor” soils are usually those where carnivorous plants live. They simply get the nutrients from insects, which consist of yummy proteins made of nitrogen.

    So basically one should not really wonder why carnivorous plants need sunlight, is has not much to do with mineral nutrients in the soil. Plants do photosynthesis by taking up CO2 from the air and using energy from the sunlight in order to produce C6H12O6, Glucose. And I guess this is also what the japanese orchid steals from the fungi - sugar.

    Of course these processes do not work completely independent from each other. But Glucose, the product of photosynthesis, is not really considered a nutrient, that would be carbon.
