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.

    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

‘Carbon Removal’ An Urgent Priority To Stop Climate Change

World Resources Institute, is ensuring both emissions cuts and carbon removal efforts move ahead fast enough to ward off the worst anticipated impacts of climate change.

With climate-changing emissions still inching higher — and resulting threats from extreme weather surging — sucking greenhouse gases out of the atmosphere must become an urgent priority, backers of “carbon removal” efforts say.

“The math is quite simple,” Manish Bapna, executive vice president of the Washington-based World Resources Institute, told a panel discussion on the fledgling approach this week.
If the world overshoots the temperature goals set in the 2015 Paris Agreement on climate change, as looks increasingly likely, “carbon removal gets us back on track,” he said.

“The first imperative is to reduce emissions as quickly and deeply as possible,” Bapna said. “But there is now a second imperative… to remove carbon dioxide from the atmosphere at a large scale.”

Proposals to suck carbon out of the atmosphere range from planting many more trees, which absorb carbon dioxide to grow, to installing devices that capture carbon directly from the air.
Changing farming practices to store more carbon in soils, or producing energy by growing trees or crops, burning them and pumping underground the carbon released also could play a role, scientists say.

Interest in carbon removal technologies is growing, not least because countries from Britain to the United States have included some of them in their plans to curb climate change.
They also feature in a report, due out next month, by the world’s leading climate scientists, who say governments may have to find ways to extract vast amounts of carbon from the air if warming overshoots the lower Paris pact limit of 1.5 degrees Celsius (2.7 Fahrenheit). That overshoot is expected to happen by about 2040, according to a draft copy of the report.

“Carbon removal is really about creating options,” said Kelly Levin, a senior associate at the World Resources Institute. “If you fast forward 20 or 30 years, we want to keep options open.”

Growing urgency

The surging scale of losses to extreme weather — including the storms that smashed into the eastern United States and the Philippines this month — means more people now believe climate change needs to be curbed, said Klaus Lackner, director of the U.S.-based Center for Negative Carbon Emissions.

“I believe we are at a turning point where people are starting to see the problem needs to be solved,” said Lackner, a proponent of technology to capture carbon from the air.

Right now, the costs of carbon removal may be too high but as climate impacts worsen “eventually it will hurt, and then we will pay whatever it takes,” he predicted.

“Show me technologies that didn’t get six times cheaper in a decade when they were actually used,” he added.

Carbon removal faces many other challenges including low government spending, competition for land, and a need to move faster than finance and technology may allow, experts admitted.
For instance, capturing carbon dioxide directly from the air, while possible, also requires a lot of energy, said James Mulligan, a World Resources Institute researcher on carbon removal.

Capturing just 15 percent of U.S. annual emissions would use 7 percent of projected U.S. energy production in 2050, he said.

Avoiding the worst

Farming differently to store more carbon in soils, by comparison, could be cheaper and provide extra benefits, boosting harvests, water conservation and wildlife habitats, said Betsy Taylor, president of consulting firm Breakthrough Strategies and Solutions.

“This pathway is the most affordable, technologically ready and it is a no-regrets option,” particularly as about a third of the world’s soils are now considered degraded, she said.

Experimenting with carbon removal deserves “a newfound sense of urgency” not least because more intrusive “geoengineering” ideas, such as blocking some of the sun’s rays from reaching the planet, are “coming down the pike,” she said.
But getting millions of farmers and ranchers to alter how they work would require significant investment — and monitoring carbon reductions from soil use remains an inexact science, experts admitted.

Most carbon removal technologies would get the world only a fraction of the way to solving its climate problem, they said — and the prospect of having the technologies available might be seized as an excuse to stall action to cut emissions.

“We need to be clear-eyed about the challenges,” Mulligan said.
The key, said Levin of the World Resources Institute, is ensuring both emissions cuts and carbon removal efforts move ahead fast enough to ward off the worst anticipated impacts of climate change, from worsening hunger to extreme heatwaves.
“If you look at the science, we have to pull out all the stops on mitigation and carbon removal at a scale that is completely unprecedented,” she said. (VOA)
