Where My Glaciers Are ???

The need to generate power by humans led to depletion of fossil fuels at a very faster rate . It is the main cause for the carbon-dioxide emission into the atmosphere. Humans are emitting Carbon-dioxide at a very faster rate than the absorption made by the plants and oceans.

A report from National Geographic news says that humans have caused almost all the present days planetary warming, Based on the project report submitted by 2500 scientists in 130 countries.Humans have polluted the earth to such an extent that even if the emissions are made to be stopped today, the global warming wouldn't stop all of a sudden.Desertification has been increased in many places . For example the boundaries of Thar desert and Gobi desert is been increasing day-by-day. It led to a situation of food shortages in many places.Natural disasters have become common in many parts of the earth. Millions of species are in the level of extinction because of the disturbance made to their habitat by man-made causes, Ecosystem change and Ocean acidification.Global warming causes the glaciers to melt eventually and it leads to the rise in the sea-level , which creates water shortages in the places or regions dependent on run-off for fresh water.Data clearly reveals that India has not only turned hot in the last two decades, the duration and frequency of heat waves has increased to a greater extent which caused more number of deaths.

According to scientists from Indian Institute of tropical meteorology, In India 2015, 25000 deaths were made to be recorded by the heat waves.National oceanic and atmospheric administration (NOAA) said that for 2016, till date the global average temperature was 2.07 degree Fahrenheit above 20th century average. It is the highest temperature in 18802016 . It is a record breaking term when compared to 2015 by 0.5 degree Fahrenheit.The particulate pollution from fossil- fueled power plants leads to impaired lung function , Shortness of breath , pre-mature death and many more diseases ,Usage of renewable energy is the only remedy to overcome the above situation , Where thousands of lives can be saved . Renewable energy lessen the threat to climatic change , Human health , Air- pollution , Depletion of water resources and other pollution


Yellow LED got burned, green LED didn't closed

Majenko already mentioned the reason. Maybe it's good to add that different colored LEDs (and even each type/model) should have its 'calculated' resistor.Find the forward voltage of the LED (differs per type/color), and use the following formula :E.g. if the forward voltage is 2V and you use a 5V Arduino and want 20 mA:The maximum mA you can find also in the data sheet of the LED.

Shane Greenes Gem Led to a Yankees Win Over the Orioles
caption idattachment_2265" alignaligncenter width300"Shane Greene pitching for the Trenton Thunder./captionThe 30 win by the Yankees over the Baltimore Orioles on Saturday afternoon ended their two-game losing streak. Shane Greene has now picked up a win in each of his first two major league starts, and he appears to be able give the team more starts like this because of his dominating stuff.Greene was aggressive against the dangerous Orioles lineup, which helped him leave his second start with an outstanding 1.32 ERA. He has only allowed two earned runs in his 13.1 innings pitched and hasnt allowed a hit in his first 4.2 innings in each of his first two starts.He threw 7.1 shutout innings against the Orioles, had an impressive nine strikeouts while only giving up four hits. In an interview on the field after the game, Greene said that he feels that all of his pitches were working.I felt pretty confident in everything today, Greene said. More than anything I just trusted Cervelli and threw everything with conviction. It is definitely an opportunity and Im trying to make the best of it. I like where I am at.The Orioles had runners on second and third with two outs in the fifth but Greene got a big strikeout against Nick Hundley. Cervelli said that he was throwing his sinker and slider very well.In the third inning, the Yankees scored their first run off of a double to deep right that scored Brett Gardner. Teixeira drove in his team-leading 48th run.In the seventh inning, the Yankees scored their second and third runs off of Orioles starter Chris Tillman. Kelly Johnson advanced to second with one out after a wild pitch by Tillman. Derek Jeters single to left drove in Jeter, and Jeter advanced to second on the throw. Jacoby Ellsbury hit a double near the line in right to score Jeter to give the Yankees a 30 lead. He leads the team with 20 doubles.The Yankees had nine hits in the win, highlighted by three by Brian McCann and two by Jeter. McCann is improving at the plate as he now has two multi-hit games in a row.Zelous Wheeler, who came into the game as a defense replacement, made an outstanding leaping catch at third for the first out of the ninth inning. David Robertson struck out Chris David and J.J. Hardy to record his 23rd save in 25 chances. He has a 2.76 ERA, 59 strikeouts and only 10 walks. He has recorded multiple strikeouts in seven of his last 10 appearances.Joe Girardi was impressed that Greene was able to step up with runners on base. His innings were pretty short and he got some big outs when he had to, Girardi said. He didnt walk people. He was ahead in the count and didnt beat himself.So far this season, the Yankees are in impressive 32 and 12 when they score first. They are also 64 on their current road trip, which ends tomorrow, and after going 411 in Saturdays game, have hit an impressive .304 with runners in scoring position.They are now four games behind the first place Orioles, and Chase Whitley will look to help them decrease the deficit on Sunday, which will be the last game before the All-Star break. It is important that they go into the break with momentum, and being three games out with all of the injuries to the rotation and offensive underperformance would be impressive.·RELATED QUESTIONAre green led lights legal to drive with as underbody kits?If you can buy them over the counter they must be legal
Alternatives to 311: a Citizen-led Movement for Change
311 is a toll-free, non-emergency phone number that people in many cities can call to get information about municipal services (like trash collection), make complaints (like a pothole), or report urgent problems (like a downed power line). Even in cities where a number other than 311 is used, 311 is the most recognized name for this type of phone system. In many places, 311 is now also available as a smartphone app.Residents are the natural eyes and ears of their neighborhoods, so any system that amplifies their voices straight to city hall gets a gold star from ioby. But what about those residents who want to do more than make a 30-second call to 311 when they notice something amiss on their block? What can neighbors do when they decide its not enough to make a report they also need to take some action?Were proud to introduce you to three ioby Leaders who saw opportunities for improvement where they live, and who didnt wait for someone else (even the government) to step in. While their projects are quite different in nature, they all used iobys crowdfunding platform to raise the money needed to make them happen.1) Community phone banking: A super-sized version of 311!Michalyn Easter raised almost $2,000 for her project Friends of Chelsea Greenline Advocacy Group, which gave North Memphians an official voice in the development of their neighborhoods new greenway. Following that win, Michalyn began leading a different kind of project to improve health, safety, and quality of life where she lives: a 311 phone bank group. The group meets monthly over donuts to make service requests to the city, and submits them all under the same account so they can easily track their success rate. (Last time we checked, they were sitting at an impressive 98 percent.)Michalyn says: I think the group has made some people more aware of what we can do about our surroundings. Theyre not just standing there anymore, shaking their heads and saying, Oh, the neighborhoods gone down. Together, were showing the city that they cant just take care of the wealthiest areas. In North Memphis, we pay taxes, too, and we care about our quality of life as well.

She became a crossing guard to help protect other vulnerable pedestrians from reckless drivers, and she raised money on ioby to outfit her intersection with traffic cones, roll-out speed bumps, sidewalk chalk, planters, and signage.Miss Lucille says: Its a dedication to life, for me. Its about helping those who are especially at risk the young, the elderly, the disabled cross safely, and asking them about their day as they go. I talk to them about positive things, and how good theyre doing. You have kids that come to school at 7:15 in the morning, and theyre walking in the dark. Whos watching out for them? Nobody. Im their eyes.3) Cooper/Higbee Underpass Mural & Central Ave Underpass Mural: From somebody should to why not me?!Betsy Robinson saw herself as a nurse practitioner not a community organizer or local leader. When her family moved to Memphis, she would remark to her kids about the ugly underpass walls they had to walk by to get to their neighborhood park. When she wondered aloud to a friend why someone didnt paint a couple of murals there, her friend wisely replied, So do it! Not long after, Betsy was the proud co-parent of not one but two beautiful murals that sparked media attention, employed local artists, and lifted her neighborhood up.Betsy says: I honestly never thought I would do anything like this, ever. But I went about it hoping that my kids would see that Im not just complaining about the place I live Im actually able to do something about it. I wanted them to see that we have the ability to make a change.

Evaluating Green Bonds: More Information Will Boost Investor Confidence
Financial industry experts and policymakers agree that green investing, led by the private sector, is one of the keys to protecting the environment and accelerating the transition to a sustainable low-carbon economy. The growing popularity of financial innovations like green bonds underscores how rapidly progress is being made toward those goals.But how can investors be sure a green bond is actually delivering on its promises? As the green bond market develops, credit rating firms and other industry players are offering evaluation tools to provide more and better information for investors.Green bonds work just like other corporate or government debt securities, with a set interest rate and repayment of principal over an agreed upon time frame. The key difference is that the capital raised by the bond issue is pledged to environmentally friendly ends, such as cleaner renewable energy technologies like solar and wind power; sustainable land use and construction projects; or environmentally friendly transit systems that reduce carbon emissions, for example.These financial instruments scarcely existed a decade ago, but since then the market for green bonds has grown dramatically worldwide. Moodys Investor Services estimates green bond issuance volume will nearly double to $75 billion this year, according to a report in the International Business Times.Growing investor demand also means a growing demand for reliable information about green investment vehicles and their results. The lack of a commonly accepted definition of green investing in this emerging market has made it difficult to quantify and validate the success of these projects.After all, green investors arent interested only in their bottom-line returns they also want to know their investment is having the desired environmental impact.Clear-eyed, objective analysis of green financial tools is necessary to help investors make the best decisions and gain comfort that their green investments are being used as promised. Toward that end, a number of financial sector groups are developing tools to improve reporting and assessment of green bonds. A few examples:· The International Capital Markets Association (ICMA) developed a set of Green Bond Principles to aid investors, issuers and underwriters. The principles are voluntary guidelines that recommend transparency and disclosure and promote integrity in the development of the green bond market by clarifying the approach for issuance.· Moodys Investors Services launched a green bond assessment (GBA) program in March 2016 offering a consistent, standardized and transparent framework for evaluating an issuers approach for managing, administering, and allocating proceeds to and reporting on environmental projects financed by green bonds. Since then, Moodys has assessed several green bond issuances, including its first U.S. green municipal bond for a water project in New Yorks Upper Mohawk Valley.· Likewise, Standard & Poors (S&P) Global Ratings introduced its own Green Bonds Evaluation framework in September. The S&P product assesses green bond projects based on transparency, governance and effectiveness in mitigation and adaptation.Those are just a few examples others are quickly stepping up to offer competing products. This flourishing of information signals the evolution of the still relatively young green bond market; over time, more and better metrics will help investors compare qualitative performance of bonds. Thats an important first step toward a reliable rating system for green bonds, which will boost investor confidence in this growing sector.Proponents of green finance rightly emphasize how these investments will go a long way toward building a more sustainable economy, while sparking renewed economic growth and creating new jobs. Enhanced disclosure and transparency will serve to nurture greater confidence in the potential of green finance to address some of the most pressing global challenges.Matt Donohue, Moodys senior vice president for global product management, explains that green bond market is positioned to continue growing, bolstered by improved information and reporting that helps investors to better assess the performance.We are seeing a growing number of investors, issuers and intermediaries who believe that green bonds are particularly well-suited as a source of capital to finance a transition to a low-carbon economy, Donohue says. Capital market financing needs combined with rising demand for socially responsible investments, standardization of offerings and the issuance of benchmark-sized deals that are effectively priced should increase green bond issuances for years to come.The road to a sustainable green economy isnt going to be easy. But the rise of green finance, including the introduction of innovative tools to assess the performance of green securities, is a welcome development that will help to smooth the path forward·RELATED QUESTIONYellow LED got burned, green LED didn't closedI'm expecting that the green LED should also be burned, because I think, that's the way how LED's work.LEDs get burned from excessive heat that is the result of excessive current.

One Thing You Can Learn in 2 Minutes That Will Be Useful for the Rest of Your Life
In 430 BC, the second year of the Peloponnesian War, Greek general led a fleet of over 100 ships towards the enemy island.As they were charging ahead at full speed, suddenly, a solar eclipse cast the entire fleet into darkness.Unaware of the scientific nature of this unexpected and shocking event, panic befell the soldiers and sailors. But not .He took off his black cloak, walked to the navigator of his ship, held it around his head and asked the man: Are you afraid of what you see?Looking at nothing but a piece of black cloththe man replied: No, of course not! countered: So what does it matter, if the cause of the darkness is a different one?When we dont understand something, our minds conjure the wildest, most sinister and dismal explanations. The result is fear and fear leads to bad decisions.But when we question our own perspective, we find we can often explain the fear away.Perspective is everything.The beauty in that is were free to change our perspective at any second.We can choose to try different angles of looking at any situation, to break it down into its parts, to look past it, around it or through it, until we find the perspective we need to move forward.Man does not simply exist but always decides what his existence will be, what he will become the next moment. By the same token, every human being has the freedom to change at any instant.Viktor FranklIf you pause for a moment to remember this story, itll be useful for the rest of your life.I myself first learned it from Ryan Holidays book, The Obstacle Is The Way, for which I wrote a summary here.This article started as an answer on quora.com·RELATED QUESTIONHow to make a green LED as visually bright as a 0 magnitude star?This is not a full answer, as I don't know how to compare an led with a candle, and I am not sure than the "answer" makes sense, even in rough estimate terms. Please just treat it as background and I will then delete it. Candle Study AbstractUsing CCD observations of a candle flame situated at a distance of 338 m and calibrated with observations of Vega, we show that a candle flame situated at 2.6 km (1.6 miles) is comparable in brightness to a 6th magnitude star with the spectral energy distribution of Vega. The human eye cannot detect a candle flame at 10 miles or further, as some statements on the web suggest.Wikipedia says, as you already know:A magnitude 1 star is exactly a hundred times brighter than a magnitude 6 star, as the difference of five magnitude steps corresponds to $(2.512)^5$or 100. But this does not make much sense either, especially when you go up another magnitude scale to mag 0.Comparing units of light power brings us back to the dark ages (sorry). One candlepower is the radiating power of a light with the intensity of one candle. This unit is considered obsolete as it was replaced by the candela in 1948, though it is still in common use. 1 candlepower is equal to about 0.981 candela. candelaThe standard unit for measuring the intensity of light. The candela is defined to be the luminous intensity of a light source producing single-frequency light at a frequency of 540 terahertz (THz) with a power of 1/683 watt per steradian, or 18.3988 milliwatts over a complete sphere centered at the light source.
