Global warming

What is it ?

The solar laser come on to the surface of earth and some return to upward and laser are clash with Green house layer but Co2 absorb it and back to Earth . When the so many laser are back to the Earth, They can heat the Earth. Therefore, the thaw the snow and increase sea surface with many kind of problems

What Causes Global Warming?

Greenhouse GasesCarbon Dioxide +0.9 KMethane +0.27 KOther greenhouse gases +0.4 K

Warming particlesFossil-fuel soot +0.3 K

Heat island < +0.1 K

The nuclear industry, supported by some governments, has seized on global warming as an opportunity to promote nuclear energy as a Co2-free solution to global warming.

Nuclear power for global warming

Generation of electricity by nuclear power plants is not a viable response to this crisis.

There are only two potential ways thatnuclear power could tackle global warming:

By using current nuclear power plants already online.

By building and using new nuclear power plants.

435 nuclear plants worldwide.

Today

Half of today’s plants will be too old to operate.*

(assuming 40-year lifespan)

By 2025

In reality, total operating capacity will decrease, not increase

Using current nuclear power plants to fight global warming would require an impossible increase in utilized capacity.

Nuclear Power in Japan

Reduction in plant safety, stability.

Japan Target of 88%*

“88% utilized capacity”

target is unrealistic.

Nuclear power is Nuclear power is unreliable for fighting unreliable for fighting global warmingglobal warming..

Scandals, earthquakes and accidents can Scandals, earthquakes and accidents can shut down numerous plants simultaneously.shut down numerous plants simultaneously.

New nuclear power is so costly that shifting a dollar/euro from nuclear to efficiency protects the climate four to seven times more than shifting a dollar/euro of spending from coal to nuclear.*

Nuclear power will make global warming worse.

Nuclear power — too costly to matter

Nuclear power is NOT the answer to global warming.

Reducing energy demand though conservation and efficiencyMicro power renewables
