Question

Selection of project global warming information

Answer 1

Many people and governments are already working hard to cut greenhouse gases, and everyone can help.

Researchers Stephen Pacala and Robert Socolow at Princeton University have suggested one approach that they call “stabilization wedges.” This means reducing GHG emissions from a variety of sources with technologies available in the next few decades, rather than relying on an enormous change in a single area.  They suggest 7 wedges that could each reduce emissions, and all of them together could hold emissions at approximately current levels for the next 50 years, putting us on a potential path to stabilize around 500 ppm.

There are many possible wedges, including improvements to energy efficiency and vehicle fuel economy (so less energy has to be produced), and increases in wind and solar power, hydrogen produced from renewable sources, biofuels (produced from crops), natural gas, and nuclear power.  There is also the potential to capture the carbon dioxide emitted from fossil fuels and store it underground—a process called “carbon sequestration.”

In addition to reducing the gases we emit to the atmosphere, we can also increase the amount of gases we take out of the atmosphere.  Plants and trees absorb CO2 as they grow, “sequestering” carbon naturally.  Increasing forestlands and making changes to the way we farm could increase the amount of carbon we’re storing.

Some of these technologies have drawbacks, and different communities will make different decisions about how to power their lives, but the good news is that there are a variety of options to put us on a path toward a stable climate.

Information regarding Global Warming

• Global Warming is an increase in the earth's atmospheric temperatures widely due to an increase in the greenhouse effect resulting especially from pollution.
• Global warming is melting of ice from poles because of the increase in the extent of carbon dioxide. If due to global warming all the ice from our poles melt into water, the water level on earth increases and submerge the land.
• Another major cause of global warming is deforestation.
• Sea levels are expected to rise between 7 and 23 inches (18 and 59 centimetres) by the end of the century, and continued melting at the poles could add between 4 and 8 inches (10 to 20 centimetres).
• Less fresh water will be available.
• Species that depend on one another may become out of sync. For example, plants could bloom earlier than their pollinating insects become active.
• Natural calamities and disaster would occur at lesser frequencies and with more destructive power. Hurricanes and other storms are likely to become stronger.
• Severe heat waves would lead to death of millions of people all around the world.
• While the idea of swimming in a warmer ocean is pleasant to most human beings, increasing ocean temperatures could cause serious ecological damage.
