Alona [7]

Answer:

$T = 3.23 \times 10^{-83}$

Explanation:

thickness of aerosol layer is 2.5 km

zenith angle is 40 degree

we know that

$\tau = \epsilon_{ext} . h$

where

$\epsilon_{ext} = N.\sigma_{ext}$

$\epsilon_{ext}$ is extinction coefficient

$\sigma_{ext}$ extiction cross section

N = Concentration

$\sigma_{ext} = (2.5 + 0.45)\times 10^{-12} m^2$

$= 2.95 \times 10^{-12} m^2$

$\epsilon_{ext} = 2\times 10^7 \times 2.95 \times 10^{-12} m^2 \times m^{-3}$

$= 5.9 \times 10^{-5} m^{1}$

$\tau = 5.9 \times 10^{-5} m^{-1} \times 2.5\times 10^3 m$

$= 14.75\times 10^{-2}$

transimiitance $T = e^{\frac{-\tau}{\mu}}$

$T = e^{\frac{- 14.75 \times 10^{-2}}{cos 40}}$

$T = 3.23 \times 10^{-83}$

Much debate has occurred between people who say climate change is a hoax and should not be addressed and people who say climate

Oksi-84 [34.3K]

Answer:

My thoughts as below.

Explanation:

Climate change s the process of changes in the level of global sea level and climatic weather patterns around the world that affects the entire ecosystem and carrying capacity of the earth hence, the climate has become such a great phenomenon and the need to address this is quite large.

climate change includes the depletion of ozone that is natural gas that encircles and protects the earth from the harmful effects of the sun and solar activity. We, humans, have destroyed the sustainable fashion of the planet to protect itself at the time of any violent catastrophes.

The grave threat of climate is being realized currently due to the face the climate now is getting out of the hands of the people and this is evident in form of flooding that occurs every tear massive depletion of natural resources and emissions of greenhouse gases.

And the continuous release of harmful gases on earth and the depletion of resources that are needed for the future of the planet is causing many humans to think of living on the moon and other earth-like planets.
