Climate Change a Real concern

Climate change is my major concern than the data privacy,due to the human activity the earth had lost everything from its resources to the biodiversity.We need to act faster on the climate change than any.we need to make laws for the protection of environment.There is no option called planet 2.I have seen a real face of climate change in recent years,there is a clear evidence of climate change.

The Earth’s climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.

There has been a great deal of incontrovertible evidence of climate change that simply can’t be ignored any longer.

The world has been gradually changing for the past years and most of these changes, unfortunately, are not even good changes at all.

On the contrary, the effects of climate change will be devastating to the human race along with every other species on the planet.

Rising Temperatures

  • The ten hottest years ever recorded all took place since 1998, with the hottest one of all being 2016.
  • Clearly, the rising of the global temperature is strong evidence of climate change. Since the 1880s, it has been noted that the Earth is continuously warming up, most of which took place in the 1970s. During the 2000s, decline of the solar output happened, which resulted to a unique deep solar from 2007–2009. Up to now, the Earth’s temperature is still rising.
  • The increasing temperature of the oceans is also an evidence of climate change. Experts noted that the oceans are absorbing the sun’s heat in an increasing rate. Warming has increased since the year 1969 wherein the oceans showed warming at 0.302 degrees Fahrenheit. Incidentally, the increase in carbon dioxide in oceans has also led to ocean acidification.

Melting of Glaciers and Polar Ice Caps

  • The ice sheets, particularly those in Greenland and in the Antarctic, are quickly melting. In fact, the melting of glaciers happening around the world is actually worse than what scientists had predicted just a few years ago.
  • The withdrawal of the glacial formations in several parts of the Earth, particularly those in the Himalayas, Africa, Alps, Andes, Alaska, and Rockies as a reaction to the twentieth century global warming is yet another evidence of climate change. Since 1966, the reduction of the snow cover has already reached the extent of about 10%.

Floods

 In 2018 Kerala received heavy Monsoon rainfall, which was about 116% more than the usual rain fall in Kerala, on the mid-evening of 8 August, resulting in dams filling to their maximum capacities; in the first 48 hours of rainfall the state received 310 mm (12 in) of rain. Almost all dams had been opened since the water level had risen close to overflow level due to heavy rainfall, flooding local low-lying areas. For the first time in the state’s history, 35 of its 54 dams had been opened. The deluge has been considered an impact of the global warming.Its not just only Kerala is effected there are many stories need to speak which is an effect of climate change.

Solutions for Climate Change:

Forego Fossil Fuels — The first challenge is eliminating the burning coal, oil and, eventually, natural gas. This is perhaps the most daunting challenge as denizens of richer nations literally eat, wear, work, play and even sleep on the products made from such fossilized sunshine. And citizens of developing nations want and arguably deserve the same comforts, which are largely thanks to the energy stored in such fuels.

Oil is the lubricant of the global economy, hidden inside such ubiquitous items as plastic and corn, and fundamental to the transportation of both consumers and goods. Coal is the substrate, supplying roughly half of the electricity used in the U.S. and nearly that much worldwide — a percentage that is likely to grow, according to the International Energy Agency. There are no perfect solutions for reducing dependence on fossil fuels (for example, carbon neutral biofuels can drive up the price of food and lead to forest destruction, and while nuclear power does not emit greenhouse gases, it does produce radioactive waste), but every bit counts.

Purchasing energy-efficient gadgets can also save both energy and money — and thus prevent more greenhouse gas emissions. To take but one example, efficient battery chargers could save more than one billion kilowatt-hours of electricity — $100 million at today’s electricity prices — and thus prevent the release of more than one million metric tons of greenhouse gases.

Swapping old incandescent lightbulbs for more efficient replacements, such as compact fluorescents (warning: these lightbulbs contain mercury and must be properly disposed of at the end of their long life), would save billions of kilowatt-hours. In fact, according to the EPA, replacing just one incandescent lightbulb in every American home would save enough energy to provide electricity to three million American homes.

Future Fuels — Replacing fossil fuels may prove the great challenge of the 21st century. Many contenders exist, ranging from ethanol derived from crops to hydrogen electrolyzed out of water, but all of them have some drawbacks, too, and none are immediately available at the scale needed.

Biofuels can have a host of negative impacts, from driving up food prices to sucking up more energy than they produce. Hydrogen must be created, requiring either reforming natural gas or electricity to crack water molecules. Biodiesel hybrid electric vehicles (that can plug into the grid overnight) may offer the best transportation solution in the short term, given the energy density of diesel and the carbon neutral ramifications of fuel from plants as well as the emissions of electric engines. A recent study found that the present amount of electricity generation in the U.S. could provide enough energy for the country’s entire fleet of automobiles to switch to plug-in hybrids, reducing greenhouse gas emissions in the process.

But plug-in hybrids would still rely on electricity, now predominantly generated by burning dirty coal. Massive investment in low-emission energy generation, whether solar-thermal power or nuclear fission, would be required to radically reduce greenhouse gas emissions. And even more speculative energy sources — hyperefficient photovoltaic cells, solar energy stations in orbit or even fusion — may ultimately be required.

The solutions above offer the outline of a plan to personally avoid contributing to global warming. But should such individual and national efforts fail, there is another, potentially desperate solution:

Experiment Earth — Climate change represents humanity’s first planetwide experiment. But, if all else fails, it may not be the last. So-called geoengineering, radical interventions to either block sunlight or reduce greenhouse gases, is a potential last resort for addressing the challenge of climate change.

Among the ideas: releasing sulfate particles in the air to mimic the cooling effects of a massive volcanic eruption; placing millions of small mirrors or lenses in space to deflect sunlight; covering portions of the planet with reflective films to bounce sunlight back into space; fertilizing the oceans with iron or other nutrients to enable plankton to absorb more carbon; and increasing cloud cover or the reflectivity of clouds that already form.

All may have unintended consequences, making the solution worse than the original problem. But it is clear that at least some form of geoengineering will likely be required: capturing carbon dioxide before it is released and storing it in some fashion, either deep beneath the earth, at the bottom of the ocean or in carbonate minerals. Such carbon capture and storage is critical to any serious effort to combat climate change.

Stop Cutting Down Trees — Every year, 33 million acres of forests are cut down. Timber harvesting in the tropics alone contributes 1.5 billion metric tons of carbon to the atmosphere. That represents 20 percent of human-made greenhouse gas emissions and a source that could be avoided relatively easily.

Improved agricultural practices along with paper recycling and forest management — balancing the amount of wood taken out with the amount of new trees growing — could quickly eliminate this significant chunk of emissions.

And when purchasing wood products, such as furniture or flooring, buy used goods or, failing that, wood certified to have been sustainably harvested. The Amazon and other forests are not just the lungs of the earth, they may also be humanity’s best short-term hope for limiting climate change.

In response to climate change, land is key. Today, agriculture, forestry, and other land uses account for roughly a quarter of global greenhouse-gas emissions. But adopting sustainable land management strategies could provide more than one-third of the near-term emission reductions needed to keep warming well below the target — 2°C above pre-industrial levels — set by the Paris climate agreement.

Conservation organizations like mine have long been working to balance the interaction between people and nature. But only recently have we fully grasped just how important land-use management is in addressing climate change. With the development of remote sensing, artificial intelligence, and biogeochemical modeling, we can better forecast outcomes, and develop strategies to manage and minimize adverse consequences.

Some of the most promising ways to mitigate climate change are what we call “natural climate solutions”: the conservation, restoration, and improved management of land, in order to increase carbon storage or avoid greenhouse-gas emissions in landscapes worldwide.

In 2016, the world witnessed a dramatic 51% increase in forest loss, equivalent to an area about the size of New Zealand. We need to buck this trend now, and help the world realize that land-use planning is not simply a conservation story.

Some countries are moving in the right direction. The Indian government, for example, has set aside $6 billion for states to invest in forest restoration. In Indonesia, the government created a dedicated agency to protect and restore peatlands, bogs, and swamp-like ecosystems that have immense CO2 storage capabilities.

But they are the exceptions. Of the 160 countries that committed to implementing the Paris climate agreement, only 36 have specified land-use management in their emissions-reduction strategies.

Overcoming inertia will not be easy. Forests, farms, and coasts vary in size, type, and accessibility. Moreover, the lives of hundreds of millions of people are tied to these ecosystems, and projects that restore forest cover or improve soil health require focused planning, a massive undertaking for many governments.

One way to get things moving, especially in the agricultural sector, would be to remove or redirect subsidies that encourage excessive consumption of fertilizers, water, or energy in food production. As Indian government officials reminded their peers during a World Trade Organization meeting earlier this year, meaningful agricultural reforms can begin only when rich countries reduce the “disproportionately large” subsidies they give their own farmers.

we need to conserve water for tomorrow every drop counts,i believe Micro irrigation could save water consumption for agriculture.

Advantages of Micro Irrigation Systems : More crop for every drop, early maturity, better quality & higher yield. Ideal for terrain with problematic soils & water. Saves labor cost. Yield increase up to 230%. Saves water up to 70%.
