Actually, Steve, fossil fuels contribute to the CO2 burden and particles, which is supposed to filter damaging UV rays. Warmer air does not mean more intense sun radiation.
'More diversified nutrients', explanation= Any dietary regime, vegan, vegetarian, omnivore, carnivore, may be deficient in some nutrients. So, a diet based solely on fruit, like the fruitarians do, can be very, very unhealthy after a short while. Fruit and vegetables are not enough. Fruit, vegetables, nuts, legumes, cereals, start being ore diversified. Adding something more ntrient like Tofu, soy protein, dairy products, may be very advantageous to health.
Fruit and vegetables alone are not enough. That's why the lessons insist on a diversified vegetarian diet with many nutrients. They do not recommend meat nor fish though.
Again on fossil fuels, the Gemini AI sums it up nicely.
Yes, fossil fuels significantly contribute to increased atmospheric particles, and these particles can influence solar radiation. Here's a breakdown:
Particle Emissions:
Burning fossil fuels, such as coal, oil, and natural gas, releases various particles into the atmosphere. These include:
Sulfate aerosols
Black carbon (soot)
Other particulate matter
These particles are collectively known as aerosols.
Effects on Solar Radiation:
Reflecting Sunlight: Some aerosols, particularly sulfate aerosols, have a cooling effect. They can reflect incoming sunlight back into space, thus reducing the amount of solar radiation that reaches the Earth's surface.
Affecting Clouds: Aerosols can also influence cloud formation. They can act as cloud condensation nuclei, which can alter cloud properties, such as their reflectivity and lifespan. This can also affect how much solar radiation reaches the earth.
Black Carbon's Role: Conversely, black carbon absorbs sunlight, which can have a warming effect. When black carbon settles on snow and ice, it reduces their reflectivity, leading to increased absorption of solar radiation and accelerated melting.
Net Effect:
While some aerosols have a cooling effect, the overall impact of fossil fuel combustion is a warming of the planet due to the release of greenhouse gases, primarily carbon dioxide.
The cooling effect of aerosols is relatively short-lived compared to the long-lasting warming effect of greenhouse gases.
In essence, fossil fuels do contribute to increased atmospheric particles, which can have localized and temporary effects on solar radiation.
However, the dominant and long-term effect of fossil fuel combustion is global warming due to the release of greenhouse gases.
