On average, a 1°C change in temperature is enough to put corals at risk of bleaching and death. Based on the slope of the trendline, in how many years will global temperatures be 1°C above average? Show your work and justify your answer.

It takes 50 years to rise global temperatures to 1°Celsius.

It takes 50 years to rise global temperatures to 1°Celsius if the temperature increases per decade is 0.18 °Celsius. From 1880, global temperature increased at an average rate of 0.07°Celsius (0.13°F) per decade but due to industrial revolution the average rate in global temperature increase double i. e. 0.18°Celsius.

If global temperature increases with the rate of 0.18°Celsius per decade, it takes about more that 50 years to reach global temperature to 1°Celsius so we can conclude that 50 years is needed to rise global temperatures to 1°Celsius.

answer; the correct answer is (beta)

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
