The problem and The
Climate- Human emission of greenhouse gases ( gases which trap
energy and responsible for heat) is not the sole determinant of temperature on
earth. Volcanic Eruption and other natural phenomenon are also
responsible for the change in Climate.
More Threatened with the
Report- The Earth Turning into Hothouse-
The report named as –“ Trajectories of the
Earth System in Anthropocene” published that the “Hothouse”
temperatures could stabilize 4 degree Celsius to 5 degree Celsius higher than
pre Industrial level. At present the Earth has 1 degree Celsius above
temperature than pre industrial level. It means that the Earth has 14 Degree
Celsius Temperature.
Scientists have warned that if global
temperature rise more than 2 Degree Celsius above Pre- Industrial Levels, It
will lead to hot house conditions, higher sea levels and making earth
inhabitable.
What is Feedbacks?
This 2 Degree rise in the earth's temperature
may trigger other Earth system process, often called ‘feedbacks’ that can drive
further warming- Even if we stop emitting greenhouse gas.
What will happen to
Earth?
 |
wildlife fire increases due to climate change
|
Hotter temperature melts down glaciers and which
further increases Oceans. This will certainly threaten the inhabitants of shore
land, coastal areas.
If the point of no return is crossed – it will create much higher
level of earth temperature than the past.
Consequences also include that Northern Hemisphere
struggles with deadly heatwaves and raging wildfires which most scientists
attribute to a man made change.
There will be a loss of methane hydrates from Oceanic floor;
weaker land and Ocean Carbon sink; Loss of Arctic Summer Sea ice and the
reduction of Antarctic Sea Ice and polar ice, which are reserves of fresh
water.
Solutions- Maximizing
the chances of avoiding ‘Hothouse’ state requires more than just reducing
greenhouse gas emission. The Improved Forest cover, agriculture and soil
management, biodiversity conservation and technologies that remove carbon di
oxide from atmosphere and store it underground should be focused area to work. People
must change their lifestyle to be better stewards of the Earth. Fossil fuels
must be replaces with low or zero emission energy sources.
Probability to Survive-
Hothouse earth is likely to be uncontrollable and dangerous to human
habitations. Rivers will flow; storms would wreak havoc on coastal communities.
And coral reefs would be eliminated. The curbing on Green House Gases will not
work alone. There are chances that even if human does something to prevent such
situation,- it may or may not work. The problem is with the slumbering attitude
of the communities. To protect environment each and every individual has to
contribute, including - governments, NGOS etc.
Even if humans made positive changes yet it is not
confirmed that hothouse conditions can be stopped.
