If We Start Geoengineering, There's No Going Back

When it comes to climate change, speed kills. The temperature changes that are causing heat waves, intense storms and other climate aberrations are dangerous today because they're happening so fast. The climate has indeed been as warm, and warmer even, in the past, but it reached those temperature levels over the course of thousands or millions of years — long enough for the changes to occur gradually. This time around, the climate is being altered too fast for animal and plant life to ad

What are some psychological facts that people don't know?

-
90% of people between 10–29 years sleep with their phones. It is possible to die due to a broken heart. It is called as stress cardiomyopathy. If a person sleeps a lot, then he/she is sad. Having conversation with a woman gives man improved mental strength. Intelligent people are more likely to remain faithful while in a relationship. You have a favourite song? That's because you are emotionally attached to that song. 1 in 5 people of India are mentally depressed, making it the most depressed country in the world. Most of us suffer from Phanthom Vibration syndrome. The feeling that your phone is vibrating when it's actually not. There is a gene that can cause you to be negative most of the time. It takes only 4 min. to fall in love. People who easily get distracted are more creative and tend to have more IQ. 10% of world population is left handed. The larger your signature, the larger your self esteem. The smaller your handwriting, the lesser you are open to conv...

Done By: Keerthana Sundar, Tang Xue Chun, Therese Ho, Sun Xue and Trishala At a Glance: December 25, 1642:   ·Isaac Newton born in Woolsthorpe, England. 1654:   ·Newton enrolled in the Grantham Grammar School. 1661:   ·Newton enrolled in Trinity College, Cambridge. July 1662:   ·Founding of the Royal Society. 1665:   ·Newton received his bachelor of arts from Trinity College. 1666:   ·. Newton conducted prism experiments, discovered spectrum of light, worked out his system of "fluxions," precursor of modern calculus and began to consider the idea of gravity. 1667 : Newton elected a Fellow of Trinity College. 1669:   ·Newton appointed Lucasian Chair of Mathematics at Trinity for the next thirty-four years. January 11, 1672:   ·Newton elected to the Royal Society. February 1672:   ·Newton's paper on optics and his prism experiments sent to the Society. Rivalry with Hooke began. 1670s:   ·Newton worked on the mathematics of gravitation in h...

How many solar panels are required to set up 1MW power plant?

Would you believe 150,000 panels! You asked a very open ended question. To provide a good estimate we need to make a few assumptions: 1 MW continuous ( 24 MWh / day) no other sources of energy are available operation for 3 days with heavy cloud cover the storage system will be recharges in 3 days system installed in New England (my home) able to provide 1 MW continuous even in the winter months Based on these assumptions I’ll walk you though the process. Please adjust the numbers to fit your particular situation. Step 1: Estimate solar resources We start by looking at the solar resources available at the location of interest. Based on this map the solar insolation for my home on the Southeastern Connecticut is about 2.5 kWh/m^2/day. Source:  Solar Maps | Geospatial Data Science | NREL Step 2: Estimate size of array This simple equation is all we need: Energy = η η AILS Where: η η  (Greek letter eta) = Efficiency of the solar panel.
