About Global warming, its effects on earth and human. greenhouse effect etc.

2.  Global Warming is the increase of Earth's average
surface temperature due to effect of greenhouse
gases, such as carbon dioxide emissions from
burning fossil fuels or from deforestation, which
trap heat that would otherwise escape from
Earth. This is a type of greenhouse effect.

3.  The trapping of the sun's warmth in a planet's
lower atmosphere, due to the greater
transparency of the atmosphere to visible
radiation from the sun than to infrared
radiation emitted from the planet's surface.

4.  Yes! As everyone has heard from the media,
recent years have consistently been the warmest
in hundreds and possibly thousands of years.
But that might be a temporary fluctuation, right?
To see that it probably isn't, the next graph
shows the average temperature in the Northern
Hemisphere as determined from many sources,
carefully combined, such as tree rings, corals,
human records, etc.

5.  The average temperature of the
lower troposphere has increased between 0.13
and 0.22 °C (0.23 and 0.40 °F) per decade since
1979, according to satellite temperature
measurements. Climate proxies show the
temperature to have been relatively stable over
the one or two thousand years before 1850, with
regionally varying fluctuations such as
the Medieval Warm Period and the Little Ice Age.

6.  At the outset of the talks, the expected key result was an
agreement to set a goal of limiting global warming to less
than 2 degrees Celsius (°C) compared to pre-industrial
levels. The agreement calls for zero net
anthropogenic greenhouse gas emissions to be reached
during the second half of the 21st century. In the adopted
version of the Paris Agreement,
 The parties will also "pursue efforts to" limit the
temperature increase to 1.5 °C. The 1.5 °C goal will
require zero emissions sometime between 2030 and 2050,
according to some scientists.
