GLOBAL WARMING
a cause of HeatWave
 Heat waves the very known and the killer name of this year for Karachi which has taken thousands of lives .It’s not going to be wrong if I give it the name of hidden killer. People of all ages suffered the effects of a heat wave, but the ill, very young, elderly, or over weighed were affected severely. Everyone is  giving  own  views about  this  disastrous wave some NGOs ,  media and specially rangers have done their duty  greatly to provide awareness to people about how they can save there lives from these killer heat  waves but the main thing is that how these disastrous waves generate?
A Heat wave  is generally  defined  as a period of some days to weeks of abnormally hot weather. Heat waves are a dangerous to human and animal’s health causing heat stroke, heat exhaustion, cramps, other ailments and plants as well and can cause crops to fail. Numerous studies have documented that human induced climate change has increased the frequency and severity of heat waves across the globe
Which will be move by 3 different ways Radiation, conduction, and convene.These all ways are packed in one word called global warming
 Global warming is causing more heat waves. Which becomes worst killing waves for the people of Karachi and also for the some areas of other countries that taken so many precious lives in the rate of thousands really unpredictable!
scientifically it is proved that "Global warming is one of the gravest health emergencies facing humanity. It's life-threatening and it's affecting us now," Global warming is bringing more frequent and severe heat waves if a planet's atmosphere contains radioactively gases (i.e., greenhouse gases) the atmosphere radiates energy in all directions.
.A recent study shows that Global average temperatures are now about 1.4 degrees Fahrenheit (0.85 degrees Celsius) higher than before industrialisation, when countries began burning coal, oil and natural gas in buildings, factories and cars.
Global warming also causes 18% of heavy precipitation, the report finds, a figure that will increase to 40% if temperatures continue to rise.
Urban areas often experience higher temperatures during the summer, referred to as “Urban Heat Island.” This is due to buildings, roads, and other infrastructures absorbing solar energy, resulting in higher temperatures
Unfortunately, climate models indicate that an average summer in 2050 will have even more days topping 90°F if global warming continues unabated.
Heatwaves Caused By Climate Change 75% of the Time….

Now it is really important to develop a plan of protection to save precious live now it’s time to take some action , we have to save our lives by our own  by following precautions which will help to stop these heat waves in future
