A recent study has declared that limiting climate change in the future could be more difficult due to shifting conditions in the Amazon forest. The planet’s oceans and forests have long held climate change in check because they act as massive carbon sinks, soaking up excess carbon dioxide in the […]

The Amazon rainforest has long been considered by scientists as critical to the health of the planet. Deemed the lungs of the Earth, the Amazon helps to keep the global carbon budget in balance by taking in large amounts of carbon dioxide. However, the rainforests of South America are constantly […]

How Mental Map Development Affects How We Perceive the Visual World Around Us

The results demonstrated that the visual map of the tadpoles developed naturally when the bars moved from front to back. The tadpoles that were shown the images in reverse order, however, extended nerve fibers to the wrong spots in the map, confirming that the brain would perceive those images as backwards.The results demonstrated that the visual map of the tadpoles developed naturally when the bars moved from front to back.

The brain is widely recognized as the most powerful organ of the human body. With our brains, we reason, learn, dream, plan, and perceive the world around us. Part of perception is the development of an internal mapping system based on visual cues. A new study from The Scripps Research […]

New Study Discovers the Worst Drought of the Millennium Occurred in 1934

Monthly 700 hPa vertical velocity anomalies (Pa/s) from October of 1933 through March of 1934, calculated from the 20th Century Reanalysis. All anomalies are calculated relative to the baseline period of 1931–1990.Monthly 700 hPa vertical velocity anomalies (Pa/s) from October of 1933 through March of 1934, calculated from the 20th Century Reanalysis.

According to the National Aeronautics and Space Administration (NASA), the worst drought of the last thousand years occurred in 1934 at the height of the Dust Bowl and Great Depression. Scientists from NASA and the Lamont-Doherty Earth Observatory found that 1934 had the driest and most widespread drought in a […]

New Record Extent of Sea Ice in Antarctica

On Sept. 19, 2014, the five-day average of Antarctic sea ice extent exceeded 20 million square kilometers for the first time since 1979, according to the National Snow and Ice Data Center. The red line shows the average maximum extent from 1979-2014.

The polar regions of the Earth, the Arctic Ocean and Antarctica, are of particular concern to scientists and researchers. In one sense, these areas act much like an air conditioner for the planet because of their cold, icy environments and the fact that like they reflect a high degree of […]

Melt Ponds and the Prediction of Ice Melt

A digital camera on NASA’s ER-2 airplane captured this top-down view of a melt pond atop a glacier in southeastern Alaska on July 16, 2014. Chunks of ice float on the pond’s turquoise water.

One of the biggest environmental concerns is that of global climate change. Symptoms of major shifts in the Earth’s climate are everywhere from the melting of glaciers, rising oceans, more severe storms, and warmer temperatures. Of particular worry to scientists and researchers is that of the melting of sea ice. […]
