Global
warming is already under way. The evidence is vast and the urgency of
taking action becomes clearer with every new scientific study. Some
of the most obvious signs are visible in the Arctic, where rising
temperatures and melting ice are dramatically changing the region’s
unique landscapes and wildlife—as well as people’s lives and
livelihoods. Across the globe, other early warning signs include
melting glaciers, shifting ranges of plants and animals, and the
earlier onset of spring.
1.What
is global warming?
Global
warming is the rise in the average temperature of Earth's atmosphere
and oceans. Warming of the climate system
is
unequivocal, and scientists are more than 90% certain that it is
primarily caused by increasing concentrations of greenhouse gases
produced by human activities such as the burning of fossil fuels and
deforestation.
2.What
is the process involved in the greenhouse effect? The
greenhouse
effect
is
a process by which thermal radiation from a planetary surface is
absorbed by atmospheric greenhouse gases, and is re-radiated in all
directions. Since part of this re-radiation is back towards the
surface and the lower atmosphere, it results in an elevation of the
average surface temperature above what it would be in the absence of
the gases.
3.What
signs warn us about global warmming? Some
of the most obvious signs are visible in the Arctic, where rising
temperatures and melting ice are dramatically changing the region’s.
Across
the globe, other early warning signs include melting glaciers,
shifting ranges of plants and animals, and the earlier onset of
spring.
4.Can
you quote another term for global warming? For climate change we
should take measures, we need to improve and care for our planet.
5.Watch
the video and explain this idea: Global warming: panic or reality? Reality.
This is starting to affect our planet, and people are starting to
destroy it. I help improve our planet and destroying more than it
already is.
6.What
can we do to stop global warming? Suggest five ideas. -.Move
more bike, walk... So it contaminariem. Cars, motorcycles ... Pollute
a lot.- Recycled products.
- Use public transport more.
- When we go to buy, use bags you have already used before.
- Take advantage of daylight, heat ...
