New Interactive Map Highlights Effects of Sea Level Rise
By Kristy Dahl
Last week, the Union of Concerned Scientists released a report showing sea level rise could bring disruptive levels of flooding to nearly 670 coastal communities in the U.S. by the end of the century.
Along with the report, UCS published an interactive map tool that lets you explore when and where chronic flooding–defined as 26 floods per year or more–will force communities to make hard choices. It also highlights the importance of acting quickly to curtail our carbon emissions and using the coming years wisely.
Here are a few ways to use this tool:
1. Explore the expansion of chronically inundated areas.
Sea level rise will expand the zone that floods 26 times per year or more. Within the "Chronic Inundation Area" tab, you can see how that zone expands over time for any coastal area in the lower 48 and for two different sea level rise scenarios (moderate and fast).
2. Explore which communities join the ranks of the chronically inundated.
We define a chronically inundated community as one where 10 percent or more of the usable land is flooding 26 times per year or more. With a fast sea level rise scenario, about half of all oceanfront communities in the lower 48 would qualify as chronically inundated. Check out the "Communities at Risk" tab to see if your community is one of them.
3. Visualize the power of our emissions choices.
Drastically reducing global carbon emissions with the aim of capping future warming to less than two degrees Celsius above pre-industrial levels–the primary goal of the Paris agreement–could prevent chronic inundation in hundreds of U.S. communities. Explore the "Our Climate Choices" tab to see the communities that would benefit from swift emissions reductions.
4. Learn how to use this time wisely.
Our country must use the limited window of time before chronic inundation sets in for hundreds of communities, and plan and prepare with a science-based approach that prioritizes equitable outcomes. Explore our "Preparing for Impacts" tab and consider the federal and state-level policies and resources that can help communities understand their risks, assess their choices, and implement adaptation plans. This tab captures how we can use the diminishing response time wisely.

At first glance, you wouldn't think avocados and almonds could harm bees; but a closer look at how these popular crops are produced reveals their potentially detrimental effect on pollinators.
Migratory beekeeping involves trucking millions of bees across the U.S. to pollinate different crops, including avocados and almonds. Timothy Paule II / Pexels / CC0<p>According to <a href="https://www.fromthegrapevine.com/israeli-kitchen/beekeeping-how-to-keep-bees" target="_blank">From the Grapevine</a>, American avocados also fully depend on bees' pollination to produce fruit, so farmers have turned to migratory beekeeping as well to fill the void left by wild populations.</p><p>U.S. farmers have become reliant upon the practice, but migratory beekeeping has been called exploitative and harmful to bees. <a href="https://www.cnn.com/2019/05/10/health/avocado-almond-vegan-partner/index.html" target="_blank">CNN</a> reported that commercial beekeeping may injure or kill bees and that transporting them to pollinate crops appears to negatively affect their health and lifespan. Because the honeybees are forced to gather pollen and nectar from a single, monoculture crop — the one they've been brought in to pollinate — they are deprived of their normal diet, which is more diverse and nourishing as it's comprised of a variety of pollens and nectars, Scientific American reported.</p><p>Scientific American added how getting shuttled from crop to crop and field to field across the country boomerangs the bees between feast and famine, especially once the blooms they were brought in to fertilize end.</p><p>Plus, the artificial mass influx of bees guarantees spreading viruses, mites and fungi between the insects as they collide in midair and crawl over each other in their hives, Scientific American reported. According to CNN, some researchers argue that this explains why so many bees die each winter, and even why entire hives suddenly die off in a phenomenon called colony collapse disorder.</p>
Avocado and almond crops depend on bees for proper pollination.

Many have opted to salvage what partial colonies survive and move away from agricultural areas.</p><p>The future of pollinators and the crops they help create is uncertain. According to the United Nations, nearly half of insect pollinators, particularly bees and butterflies, risk global extinction, Phys.org reported. Their decline already has cascading consequences for the economy and beyond. Roughly 1.4 billion jobs and three-quarters of all crops around the world depend on bees and other pollinators for free fertilization services worth billions of dollars, Phys.org noted. Losing wild and native bees could <a href="https://www.ecowatch.com/wild-bees-crop-shortage-2646849232.html" target="_self">trigger food security issues</a>.</p><p>Salazar, the beekeeper, warned Phys.org, "The bee is a bioindicator. If bees are dying, what other insects beneficial to the environment... are dying?"</p>

Australia is one of the most biodiverse countries in the world. It is home to more than 7% of all the world's plant and animal species, many of which are endemic. One such species, the Pharohylaeus lactiferus bee, was recently rediscovered after spending nearly 100 years out of sight from humans.
Scientists have newly photographed three species of shark that can glow in the dark, according to a study published in Frontiers in Marine Science last month.
