Will the 2019-nCoV virus disappear in warm weather?

The novel coronavirus causing COVID-19 is unlikely to disappear with warm weather.

French researchers have just done an experiment and found that only temperatures higher than on an extremely hot summer day could kill the 2019-nCoV virus. Researchers at Aix-Marseille University “cooked” the virus for different periods of times and at different temperatures. They found that either 1 hour at 60 ℃ or 15 minutes at 92 ℃ was the best method to inactivate the virus.

Does this mean we have to expect the same levels of infections in the summer?
Scientists can’t give a definite answer. Although earlier varieties of coronaviruses proved to be seasonal, currently we have a highly susceptible population that has not developed the necessary immunity yet. Chinese scientists, on the other hand, have developed a model suggesting that higher temperatures AND high humidity can slow the transmission of the virus.

Here is the current state of science on a Sparrho pinboard. NB: The pinboard contains research papers that have not been peer-reviewed yet, meaning that they have not gone through the standard scientific validation process yet.
