New interactive maps from NOAA show you how your region's vegetation has shifted due to climate change.
The maps are based off of the official U.S. Climate Normal, which are updated every 10 years and last updated in 2010. By averaging the coldest days each year for the 30-year window and sorting those averages into 10-degree Fahrenheit "planting zone" bins, they were able to make a continuous map with similar minimum temperatures between the two time periods.
This map shows the planting zones between 1971 and 2000.
This map shows the planting zones between 1981 and 2010.
As a whole it may not look like much has changed. But, when you zoom in on your region, you'll see that those slight changes made a huge difference. The 1970s was an unusually cool decade, while the 10 year period between 2001 and 2010 was the warmest ever recorded, causing for drastic shifts. For this reason, according to NOAA, planting zones have shifted northward and upward in elevation in many parts of the country, because warming winter nights are allowing plants to migrate. This is evident in the third map, which shows shifts in planting zones:
By basing it off of winter averages, we know that plants that used to survive in the region, may no longer make it in these changing times. Some plants need a long enough winter to go into dormancy and return in the spring to flower while other plants can't survive at all in sub-freezing temperatures. Climate.gov said these changes are also causing longer and more severe wildfire seasons, and allowing pests to thrive and spread to what used to be colder regions. Overall, this could be having adverse effects on pollination patterns, the food chain and ultimately the biodiversity of any given region.
"Species, including many iconic species, may disappear from regions where they have been prevalent or become extinct, altering some regions so much that their mix of plant and animal life will become almost unrecognizable," reported the Third National Climate Assessment in 2014.
These new "climate normals" can help people know exactly what to plant to ensure their garden is a healthy environment for native species.
Sweden's reindeer have a problem. In winter, they feed on lichens buried beneath the snow. But the climate crisis is making this difficult. Warmer temperatures mean moisture sometimes falls as rain instead of snow. When the air refreezes, a layer of ice forms between the reindeer and their meal, forcing them to wander further in search of ideal conditions. And sometimes, this means crossing busy roads.

A chance discovery of a beautifully preserved fossil in the desert landscape of Morocco has solved one of the great mysteries of biology and paleontology: how starfish evolved their arms.

<h2></h2><p>Although starfish might appear very robust animals, they are typically made up of lots of hard parts attached by ligaments and soft tissue which, upon death, quickly degrade. This means we rely on places like the Fezouata formations to provide snapshots of their evolution.</p><p>The starfish fossil record is patchy, especially at the critical time when many of these animal groups first appeared. Sorting out how each of the various types of ancient starfish relate to each other is like putting a puzzle together when many of the parts are missing.</p><h2>The Oldest Starfish</h2><p><em><a href="https://www.biorxiv.org/content/10.1101/216101v1.full.pdf" target="_blank" rel="noopener noreferrer">Cantabrigiaster</a></em> is the most primitive starfish-like animal to be discovered in the fossil record. It was discovered in 2003, but it has taken over 17 years to work out its true significance.</p><p>What makes <em>Cantabrigiaster</em> unique is that it lacks almost all the characteristics we find in brittle stars and starfish.</p><p>Starfish and brittle stars belong to the family Asterozoa. Their ancestors, the Somasteroids were especially fragile - before <em>Cantabrigiaster</em> we only had a handful of specimens. The celebrated Moroccan paleontologist Mohamed <a href="https://doi.org/10.1016/j.palaeo.2016.06.041" target="_blank" rel="noopener noreferrer">Ben Moula</a> and his local team was instrumental in discovering <a href="https://www.sciencedirect.com/science/article/abs/pii/S0031018216302334?via%3Dihub" target="_blank" rel="noopener noreferrer">these amazing fossils</a> near the town of Zagora, in Morocco.</p><h2>The Breakthrough</h2><p>Our breakthrough moment came when I compared the arms of <em>Cantabrigiaster</em> with those of modern sea lilles, filter feeders with long feathery arms that tend to be attached to the sea floor by a stem or stalk.</p><p>The striking similarity between these modern filter feeders and the ancient starfish led our team from the University of Cambridge and Harvard University to create a new analysis. We applied a biological model to the features of all the current early Asterozoa fossils in existence, along with a sample of their closest relatives.</p>Cantabrigiaster is the most primitive starfish-like animal to be discovered in the fossil record.

<p>Our results demonstrate <em>Cantabrigiaster</em> is the most primitive of all the Asterozoa, and most likely evolved from ancient animals called crinoids that lived 250 million years before dinosaurs. The five arms of starfish are a relic left over from these ancestors. In the case of <em>Cantabrigiaster</em>, and its starfish descendants, it evolved by flipping upside-down so its arms are face down on the sediment to feed.</p><p>Although we sampled a relatively small numbers of those ancestors, one of the unexpected outcomes was it provided an idea of how they could be related to each other. Paleontologists studying echinoderms are often lost in detail as all the different groups are so radically different from each other, so it is hard to tell which evolved first.</p>President Joe Biden officially took office Wednesday, and immediately set to work reversing some of former President Donald Trump's environmental policies.

In many schools, the study of climate change is limited to the science. But at the University of Minnesota, Twin Cities, students in one class also learn how to take climate action.
