much sunlight makes it
into the lower atmosphere and can reflect, buffer or trap in heat.

sunlight going
into the ocean by as
much as 10 percent.»
Sunlight and toxins do
much of the damage, but the biggest culprit may be highly reactive byproducts created as cells use oxygen to turn sugar
into energy.
It heats up in
sunlight like most other compounds, but it does not radiate its heat
into its surroundings as
much.
Cells can be made more cheaply using noncrystalline, amorphous semiconductors, but they are
much less efficient at turning
sunlight into electricity.

into the sun
much or live in climates where there isn't
much sunlight.

into a new office space that does not get
much sunlight.

into the house at different angles, the leaves change (as
much as they can in this climate), and I get to bake with all my favorite ingredients.
One night, as a child, after witnessing a vampire kill his mother but somehow not turn her
into a vampire (vampires don't fear the
sunlight in this one, either, or at least fear it only as
much as Edgar Winter does), Abe embarks on a vengeance - crusade aided by vampire hunter - trainer Henry (Dominic Cooper).
Our domestic dogs have moved
into our homes and sadly,
much like us, they do not get near enough exposure to
sunlight and its healing and life promoting benefits.
For example, if the Earth got cold enough, the encroachment of snow and ice toward low latitudes (where they have more
sunlight to reflect per unit area), depending on the meridional temperature gradient, could become a runaway feedback — any little forcing that causes some cooling will cause an expansion of snow and ice toward lower latitudes sufficient to cause so
much cooling that the process never reaches a new equilibrium — until the snow and ice reach the equator from both sides, at which point there is no more area for snow and ice to expand
into.
If you put more CO2, say,
into the stratosphere then that doesn't change how
much sunlight reaches the Earth's surface
much and the surface warms up as
much as before.

sunlight hits the
much darker open water, only 6 percent is reflected back
into space and 94 percent is converted
into heat.
The other kind of geoengineering tries to reflect
sunlight back
into space before it has a chance to heat the Earth,
much as putting up an umbrella at the beach keeps you cool by blocking the sun.
For example, solar photovoltaic (PV) cells convert
sunlight directly
into energy that people can use,
much like bioenergy, but with greater efficiency and less water use.
The results, which appear in a paper titled «Spatially Explicit Life Cycle Assessment of Sun - to - Wheels Transportation Pathways in the U.S.» and published in the Dec. 26 issue of the journal Environmental Science & Technology, showed photovoltaics (PV) to be
much more efficient than biomass at turning
sunlight into energy to fuel a car.
But
much stronger albedo effects (a measure of how
much sunlight is simply reflected back out
into space) might be generated by the high winds of the glacial era, giving 10 °C temperature changes rather than the 1 °C excursion of the Little Ice Age.
How do we convert
sunlight into energy
much more efficiently than solar panels do today?
Going forward, new solar installations are widely expected to grow at a
much slower pace than in previous years, due to tariffs that President Donald Trump imposed in January on imported solar panels and cells, the devices inside the panels that convert
sunlight into electricity.
When
sunlight strikes ice and snow, most of it is reflected back
into space, but if it instead strikes land or open water, then
much of the energy in the light is absorbed and converted
