Question

State five reasons for rise of temprature and three step to reduse it.

Answer 1

Answer:

Variations in the sun's energy reaching Earth

Changes in the reflectivity of Earth’s atmosphere and surface

Changes in the greenhouse effect, which affects the amount of heat retained by Earth’s atmosphere

Answer 2

Answer:

CAUSES: Burning coal, oil and gas produces carbon dioxide and nitrous oxide.

Cutting down forests (deforestation). Trees help to regulate the climate by absorbing CO2 from the atmosphere. So when they are cut down, that beneficial effect is lost and the carbon stored in the trees is released into the atmosphere, adding to the greenhouse effect.

Increasing livestock farming. Cows and sheep produce large amounts of methane when they digest their food.

Fertilisers containing nitrogen produce nitrous oxide emissions.

Fluorinated gases produce a very strong warming effect, up to 23 000 times greater than CO2. Thankfully these are released in smaller quantities and are being phased down by EU regulation.

WAYS TO REDUCE:

Take public transport, walk, or ride your bike.

Change to energy-efficient light bulbs, and unplug things when you're not using them.

Eat less meat( Become Vegans).
