Rising Sea Levels

One of the most significant challenges related to global climate change is rising sea levels. Since the beginning of the 20th-century, sea levels have gradually risen by 16 - 21 cm (6.3 - 8.3 in).

The rise in sea levels has also accelerated over time due to thermal expansion (the change in the volume and area of matter due to increased temperatures) and the melting of ice sheets and arctic glaciers.

Researchers have calculated that arctic sea ice has declined by 10% in the last 10 years. In addition to rising sea levels, this has altered the circulation of the Atlantic Ocean, destroying fisheries in northern countries and creating massive storms and hurricanes.

Coastlines around the world remain susceptible to flooding. Some at-risk coasts include the Miami shore, Rio de Janeiro, Osaka and Shanghai. The Egyptian city, Alexandria, faces a particular threat as much of its population exists in low lying coastal areas, which will likely be inundated within the next decade.

Our best hope for limiting the increase in sea levels is to reduce our carbon footprint. Initiatives in renewable energy and efficient power are critical components in reaching our emission goals.

The Beauty of Illustration in an Age of Photography

You may associate nature and medical illustration with dusty old tomes, but it's more relevant and beautiful than ever. In a world that's getting more complicated and where technical knowledge can make or break careers, precise and informative illustration is more critical than ever.

Illustration can show the unseen and explain the unclear. Think about a photograph of internal human anatomy. Even if it is a high resolution, super sharp image, it may still be difficult to decipher. A science or medical illustration, on the other hand, can show each anatomical part in a different color, label it, and indicate its function. Unimportant details can be left out and critical information highlighted.

In many cases, a photograph can't display the same level of detail as a well-designed illustration. Volcanos are spectacular on the outside but their inner workings are hidden from view without a well-placed cross-section. Illustrations can also represent processes such as DNA sequencing and distinctions between organisms that are similar in appearance, such as bacteria and viruses.

To this day scientific illustrations play an important role in the education of doctors, geologists, paleontologists, physicists and many other careers.  

With the advancement of 2D and 3D software and the continued efforts of talented scientific artists, illustration will continue to play an important role in the future of science education.
