Climate change: Major glaciers worldwide to disappear by 2050
Some of the world’s most famous glaciers, including in the Dolomites in Italy, the Yosemite and Yellowstone parks in the United States, and Mount Kilimanjaro in Tanzania, will disappear by 2050 because of global warming, whatever the temperature rise scenario, according to a UNESCO report.
The United Nations cultural agency UNESCO, which monitors some 18,600 glaciers across 50 of its World Heritage Sites, says one-third of those are set to disappear by 2050.
While the rest can be saved by keeping global temperature rise below 1.5 degrees Celsius (2.7 degrees Fahrenheit) relative to pre-industrial levels, in a business-as-usual emissions scenario, about 50 percent of these World Heritage glaciers could almost entirely disappear by 2100.
The study “shows these glaciers have been retreating at an accelerated rate since 2000 due to CO2 emissions, which are warming temperatures”, UNESCO said.
See, if you agree to pay taxes and give up your freedom and modern lifestyle we can save half of the glaciers. Which disappear during interglacial periods. And Holocene warm periods. It’s all about the fear mongering. But, hey, remember, this is all a science
Climate change forecasts more rainbows
Climate change will increase opportunities to see rainbows, according to a study led by researchers at the University of Hawai?i at M?noa. The study’s authors estimate that by 2100, the average land location on Earth will experience about 5% more days with rainbows than at the beginning of the 21st century. Northern latitudes and very high elevations, where warming is predicted to lead to less snow and more rain, will experience the greatest gains in rainbow occurrence. However, places with reduced rainfall under climate change—such as the Mediterranean—are projected to lose rainbow days.
So, more rainbows and less rainbows. How do they know?
A team including students at UH M?noa looked at photographs uploaded to Flickr, a social media platform where people share photographs. They sorted through tens of thousands of photos taken around the world, labeled with the word “rainbow,” to identify rainbows generated from the refraction of light by rain droplets.
Then, the scientists trained a rainbow prediction model based on rainbow photo locations and maps of precipitation, cloud cover and sun angle. Finally, they applied their model to predict present day and future rainbow occurrences over global land areas. The model suggests that islands are rainbow hotspots.
That’s it. That’s their scientific study. Looking at people’s photos of rainbows.
