There were a myriad of differences between Great Britain and her American colonies in the seventeenth and eighteenth centuries, but these differences can be divided into three basic categories: economic, social, and political.

Climate change would increase the frequency of powerful storms. Climate change, or global warming, is caused by burning fossil fuels such as coal, oil and gas, which release greenhouse gases like carbon dioxide and methane into the Earth's atmosphere and oceans. That has raised the global temperature and also worsened climate and weather disasters around the world, the U.N. has said. (61 words )

Sea-level rise is caused primarily by two factors related to global warming: added water from melting ice sheets and glaciers and the expansion of sea water as it warms. Within just a few decades, hundreds of thousands of homes on the US coast will be flooded. In fact, by the end of the century, 6 feet of ocean-level rise would redraw the coastline of southern Florida. (66 words )

In the US alone, 13 million people could be forced to relocate due to rising sea levels by 2100. As a result, cities throughout the country will grapple with new populations. Effects could include more competition for jobs, increased housing prices, and more pressure on infrastructure networks. "Sea level rise will affect every county in the US, including inland areas," said Dilkina. (62 words )

Scientists have discovered Earth's oldest asteroid strike occurred at Yarrabubba, in outback Western Australia, and coincided with the end of a global deep freeze known as a Snowball Earth.

With enough user data, future AI could eventually create a fully-customized partner for you in virtual reality — one that checks all your "boxes".

Human waste is a rich source of organisms called bacteriophages — known as "hunt and kill viruses" for their ability to bind to bacteria and destroy them.

Team members did not speak to reporters, although some waved and took pictures of the media from the bus as it departed.
