The document discusses the causes and effects of greenhouse gases and global warming, and steps that can be taken to address it. The primary cause of global warming is burning fossil fuels like oil, coal and natural gas, which releases greenhouse gases like carbon dioxide and methane into the atmosphere. This has led to increased global temperatures and rising sea levels, as well as melting glaciers. Common people can help reduce global warming by using less fossil fuels in their daily lives.

2. HIGHLIGHT THE CAUSES AND
EFFECTS OF GREENHOUSE GASES .
UNDERSTAND WHAT ALL IS GLOBAL
WARMING AND WAYS O REDUCE IT.
FURTHER STEPS TO BE TAKEN UP BY THE
COMMON PEOPLE TO PREVENT ALL THIS IN
FUTURE.

7. Global warming is the increase in the
average measured temperature of the Earth's
near-surface air and oceans since the mid-
20th century, and its projected continuation.
The average global air temperature near the
Earth's surface increased 0.74 ± 0.18 °C
(1.33 ± 0.32 °F) during the 100 years ending
in 2005.

8. •The primary human-related cause of global
warming is the burning of fossil fuels like oil,
coal, and natural gas..
•We have also put more methane, ozone, and
other greenhouse gases into the atmosphere
through industrial and agricultural production.
•We use fossil fuels every day to power our cars,
to light and heat (or cool) our homes, to
manufacture goods, and to grow food.
• CO2 – increased 30% since last industrial
revolution.
• Methane- increased by 150%

9. •The largest glacier on Mount Kenya has lost 92% of its
mass
•Sea levels have risen by 10 - 25 cm
•The thickness of sea ice in the arctic has decreased by
40%.

10. o Himalayan source of the Ganga - drying up at a rate of
40 yards a year (twice as fast as two decades ago)
o Some of these glaciers might disappear by 2030.
o In the dry summer months, the Gangotri glacier
provides up to 70 percent of the water of the Ganga.
o According to a UN climate report, the shrinking
glaciers also threaten Asia’s supply of fresh water.
