<p>China has stepped up its efforts to keep the Paris agreement in place following the U.S. withdrawal. The EU and China issued a joint statement underscoring their commitments to the Paris accord to combat climate change. China pledged to bring its carbon emissions to a peak by 2030 or earlier as part of a joint pledge made with the U.S. ahead of the 2015 Paris talks. A U.S. withdrawal puts less pressure on China to bring its emissions peak earlier, but in recent years China has sought to dominate the clean energy market.

<p>Norway's sovereign wealth fund will ask the banks in which it has invested to disclose how their lending contributes to greenhouse gas emissions. The fund has in the past measured the carbon footprint of its investments in equities and bonds, and now is pushing companies to disclose both their carbon emissions and their plans to handle the risk of climate change. The fund does not plan to change how it decides to invest in the U.S., which accounted for nearly 40% of its investments in 2016.

<p>Electric fences have been used to prevent human/elephant confrontation as development encroaches on traditional elephant habitats. But elephants are intelligent and soon discover that their tusks do not conduct electricity, allowing them to escape. Alexander Vipond of the&nbsp;Knysna Elephant Park&nbsp;in South Africa invented a simple device, nicknamed “tusk braces,” to discourage elephants from cutting fence wires. The tusk brace is basically a wire fit onto the length of the top of the tusk that turns the tusk into a conductor.
