Where My Glaciers Are ???

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.
