How do solar activity affect the earth?

Answer 1

Solar energy, direct from the sun, warms the earth. This is good, because the earth is thus warm enough for life.

In the past, before we started adding amounts of greenhouse gases to the atmosphere, there was an energy balance. Enough warmth came in, and enough escaped back out to space, to keep the temperature stable. Now, by the burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide (CO2), we are stopping some of this heat escaping to space, and the earth is warming.

Solar energy, captured on rooftops, and turned into electricity, is good for the environment and it slows global warming, because the electricity is clean, with no carbon dioxide emissions. Any electricity generated by PV panels means that less has to be generated by burning coal and oil.

A:Solar Energy does actually prevent global warming because it produces electricity without going through the process of burning fossil fuels (which is the most common reason for global warming). Not only does it generate electricity, it also:

heats water

purifies water

heats air

cooks

tells time

So all these everyday-actions can be done without burning any fossil fuels

Answer 2

The solar output is very nearly constant, with a range of variation of about 0.2%, so reproducible that it is often referred to as the "solar constant". However, sunspot activity has been shown to affect average global temperatures. Until about 1970, the cycles of sunspot activity correlated quite well with variations in global temperatures. Since 1970, greenhouse gas emissions have become much more dominant in their effect on global temperatures, and there is no longer a close relationship between sunspot activity and global temperatures.

Answer 3

Global Warming does not affect the temperature. Global Warming is the temperature -- rising!

A:It stipulates that Temperatures will globally increase; unless some Extra Huge volcanic Ash Cloud might Intervene. A:Global warming IS the average temperatures of the world. The temperature is going up. That's what global warming is.

Answer 4

Solar radiation, or the energy and heat from the sun, is the source of almost all the earth's energy. This energy warms the surface of the earth. The warmed earth then emits infrared radiation which goes up into the atmosphere. Much of this is trapped by the greenhouse gases. This makes the earth warmer, as the greenhouse gases now emit warmth in all directions, including back down to earth.

Human activity has been adding additional greenhouse gases to the atmosphere over the last 200 years, and this increase is causing an accelerated greenhouse effect which is causing global warming.

Answer 5

The sun has actually been cooling slightly over the past few decades. At the same time the earth's temperature has been rising, more rapidly than ever. This has led scientists to conclude that the sun is not causing or affecting global warming (apart from providing the warmth!).

It is the build-up of greenhouse gases in the atmosphere from the burning of fossil fuels (coal, oil and natural gas) and deforestation (cutting down trees which previously removed carbon dioxide (CO2) from the atmosphere), that is responsible for global warming.

Answer 6

No, the vacuum of space takes care of that. Nothing happening on earth can affect the sun.
