Climate change is a terrible problem, and it absolutely needs to be solved. It deserves to be a huge priorityBill Gates.

The temperature of Bengaluru is rising. Maharashtra is facing drought. Glaciers of Arctic and Antarctica are undergoing reduction. European countries are going to face flood like situation by 2020. Sea levels will rise. World will become frost free. Why it is happening? One place is very cool and the other place is too hot. Why?

Is Earth moving towards the end?
The climate of Earth is changing. Global Warming has threatened the whole sphere and the effects are likely to be significant. We can feel the change but we are quiet. According to NASA, climate change is messing up with the movement of Earth. Before 2000, Earth’s spin axis was drifting toward Canada (left globe). Climate change-driven ice loss in Greenland, Antarctica and elsewhere is pulling the direction of drift eastward.

Many such changes are being observed by the scientists happening around the globe.

Who is responsible?

“Social Animal”- the most intelligent creature on Earth is blamable. Human race is very fond of development. Doesn’t matter, how it comes? Scientists claim that there’s 90 per cent probability that human activities over the past 50 years have warmed our planet. An industrial effluent like Carbon dioxide is the major ingredient of greenhouse gas which is damaging the nature continuously. Further, the Chlorofluorocarbons (CFC’s) used in air conditioners and refrigerator is primarily responsible for the depletion of ‘ozone layer’. Ozone layer is the protection layer around the Earth which reflects back the ultra violet rays from the sun.

What would be the consequences?

  • Rising Temperature: Green House gases from power plants, Vehicle exhaust, and deforestation are mainly responsible for the increment in temperature. Scientists project that if emissions of greenhouse gas are not reduced, we can see increment of 3 to 10 degrees Fahrenheit by the end of century. One degree is enough to change the whole climatic conditions on Earth. 

 

  • Shifting of Vegetation: As the temperature of Earth will rise, it will tend to change the pattern of rainfall and snowfall. Trees and plants will adapt the Polar and Mountain Regions. Temperature of a place is an important condition for vegetation.

 

  • Irreversible Extinction: Due to severe change in climatic conditions, the wildlife will be unable to adjust with the conditions. Experts claim that 25% of Earth species could be headed for extinction due to climate change.

 

  • Rising Waters: With Earth heating up day by day, the waters in ocean and sea will rise resulting in submerging of lands. According to the report prepared by group of ecologists led by Dr. M Zafar-ul Islam, “The Indian sub-continent may lose close to 14,000 sq. km of land with the rise of 1 meter of sea level”.

 

  • Flood and Drought situation: The rise in temperature increases the risk of drought situation. Due to climate change there will be increase in summer time and decrease in spring and rainy season. Land affected by drought is more vulnerable to floods during rainy seasons. These can have an adverse effect on human health. Asia and Africa are already facing this situation. Presently Indian state, Maharashtra is facing drought.

 

  • Human Health: Due to rising temperature, people are dying of heat-related illness. Scientists have linked deadly heat waves to climate change and warn more to come. Several Bacteria, microbes and insects are finding suitable condition to breed in places which were too cool for them to adapt. In 2015, more than 2500 people died in India due to Heat stroke.

What more climate change can do? Low yield in crops are forcing millions of people to starve.

What we can do?

We cannot stop the climate change suddenly. Rather, we can slow down the change happening in nature.

Some of the conscious efforts which we can contribute are:-

  • Use less Energy:
  1. Turn OFF the appliances at home, when not in use.
  2. The energy efficient appliances can help in saving bills as well as reducing Carbon emissions.
  • Be Eco-friendly:
  1. Don’t use flights. Use a train or alternative transport.
  2. Minimize the shopping trips. Try to make a list and buy all at a time.
  3. Walk to small distances rather than using a vehicle.
  • Change your habits:
  1. Use public transports or pool a car.
  2. Shut down computer rather logging off.
  3. Spread your good habits.
  • Consume less Non-Veg:

According to a report published by Worldwatch Institute, 51 percent or more of global greenhouse gas emissions are caused by animal agriculture. So we can consume less meat, egg and dairy products to prevent global warming.

  • Teach your next generation:

It’s very important to educate the coming generation about the current situation of environment. So, pass on your habits to them so that they don’t repeat the same mistake.

Our Earth needs our attention. We still have time.

    Climate change … yes indeed earth is in danger. i guess that’s the reason people r now searching for a new planet .

    Indeed earth is in danger ..Thtat’s the reason we are now shifting our gears to different planet

    Danger is due to human activities. There should be some initiatives taken by us to reduce or compensate whatever harm we’ve done to our planet

Skyscrapers May Have Made The Impact Of Hurricane Harvey Worse: Study

The scientists projected future warming and found future versions of the same storms would be significantly wetter and stronger.

Humans helped make recent devastating U.S. hurricanes wetter but in different ways, two new studies find.

Hurricane Harvey snagged on the skyscrapers of Houston, causing it to slow and dump more rain than it normally would, one study found. The city’s massive amounts of paving had an even bigger impact by reducing drainage. Land development in the metro area, on average, increased the chances of extreme flooding by 21 times, study authors said.

A second study looked at last year’s major Hurricanes Maria and Irma and 2005’s deadly Katrina and used computer simulations to see what would have happened if there had been no human-caused global warming. The study found that climate change significantly increased rainfall from those three storms, but did not boost their wind speed.

Both studies are in Wednesday’s journal Nature.

Houston was a literal drag on Harvey as it sloshed through, with the storm getting tripped up by the skyscrapers, said study co-author Gabriele Villarini, a civil and environmental engineering professor at the University of Iowa.

Co-author Gabe Vecchi, a climate scientist at Princeton University, said that forced the storm to move up higher, causing more concentrated rain over Houston and slowing, which also made more rain.

He compared it to a river running over rocks, creating bubbles.

“That’s sort of what’s going on here,” he said.

This effect is dwarfed, though, by the paving and building that don’t allow water to sink into the ground, Vecchi said.

Harvey’s record rainfall reached 5 feet in one spot near Houston. The scientists used computer simulations to see the effects of urbanization. In parts of the Houston metro area, the effects of development ranged from a 10 percent higher risk of extreme flooding in the less developed northwest to nearly 92 times the risk in the northeast, they reported.

That’s on top of the unique weather patterns that made Harvey slow down and stall and climate change which brought more water into the storm, Vecchi said.

MIT hurricane and climate expert Kerry Emanuel, who wasn’t part of the study, called the Harvey study “a real advance in our understanding of hurricane impacts on urban areas.”

But Texas state climatologist John Nielsen-Gammon wasn’t convinced. He said the team used generic shapes instead of the actual Houston skyline. He said the storm’s wind speeds may have slowed, but that’s different from the storm’s forward movement slowing.

The other study in Nature looked at a variety of historical damaging storms and tried to calculate past and future effects of climate change. In three cases, the scientists simulated the storms without the changes in the climate from greenhouse gases, showing that global warming increased rainfall 8.9 percent in Hurricane Maria , 6.3 percent in Hurricane Irma and 8.7 percent in Hurricane Katrina .

Maria hit Puerto and Rico and other parts of the Caribbean. Irma hit the Caribbean and Florida, while Katrina struck New Orleans and the Gulf Coast.

In Maria’s case, a warming climate concentrated heavier rain in the center of the storm and reduced it on the edges, said co-author Michael Wehner, a climate scientist at the Lawrence Berkeley National Laboratory.

For 15 storms, which included the devastating Typhoon Haiyan , the potent Gilbert and 1992’s Hurricane Andrew , the scientists projected future warming and found future versions of the same storms would be significantly wetter and stronger.

“We are beginning to see a climate change influence emerge on tropical cyclones and that’s coming out as rainfall,” said study lead author Christina Patricola, an atmospheric scientist at the national lab.

Although replicating a storm in a different climate is difficult and can’t account for certain changes, this work bolsters science understanding of how climate change alters hurricanes, Emanuel said. (VOA)
