To Flee or Not to Flee: Narwhals puzzle scientists with their escape heartbeat

Take a big inhale and a deep dive. Imagine staying underwater as long as possible. Now imagine a shark approaching, with gleaming teeth, and swimming away as fast as you can. Imagine trying to do both at the same time. You are not alone if you find this confusing. Freeze and flight responses are often mutually exclusive. If you try to do both at once, … Continue reading To Flee or Not to Flee: Narwhals puzzle scientists with their escape heartbeat

The Hot, New Normal: Temperature records broken… again

For the third year in a row, global average temperature records have been broken . Earth experienced the highest temperatures since we began keeping records back in 1880 and, compared to the average temperature of the 20th century (1901-2000), 2016 was nearly a full degree Celsius (0.94 oC) higher. Furthermore, since the beginning of the 21st century, average temperature records have been broken five times … Continue reading The Hot, New Normal: Temperature records broken… again

House Science Committee Retweets A Breitbart Denial of Global Warming

In an affront to the scientific community, the Science Committee of the House of Representatives recently retweeted a questionable Breitbart article which denied global warming. The cited Breitbart article claimed that warm temperatures in 2015 were due to a particularly strong El Niño, not a longer term trend of global warming, and that previous to 2015, there was actually a “global warming hiatus.” The article was … Continue reading House Science Committee Retweets A Breitbart Denial of Global Warming

Reconsidering the Risks of Nuclear Power

by Jordan Wilkerson figures by Shannon McArdel The United States emits an immense amount of carbon dioxide into the atmosphere. According to the Intergovernmental Panel on Climate Change, it is extremely likely that the rising global temperature trends since the mid-20th century is dominantly due to human activity. No scientific organization of national or international standing disputes this. Furthermore, the US Department of Defense has … Continue reading Reconsidering the Risks of Nuclear Power

Engineering the Earth to Fight Climate Change

by Katie Dagon Imagine if we had an “undo” button for climate change – we could remove all the greenhouse gases from the air or cool the planet’s temperature in an instant. While this might sound like science fiction, the basic idea is not as far off as you might think. Reducing fossil fuel use is really important, but also really difficult. And even if … Continue reading Engineering the Earth to Fight Climate Change

Seaweed May Cut Cows Methane Production

A team of Australian scientists lead by Rocky De Nys (James Cook University) discovered that a certain type of red seaweed, called Asparagopsis taxiformis, can decrease the amount of methane produced by the bacteria found in a cow’s stomach. Lauren Kuntz explains that methane is a very potent but short-lived greenhouse gas. Limiting methane produced by livestock, a major source of the gas, could help … Continue reading Seaweed May Cut Cows Methane Production

New Study Warns of Southwest Megadrought

A new study published in Science aims to assess the effect of climate change on the risk of a serious drought hitting the Southwest United States before the year 2100. Megadroughts are defined as decade-long periods of prolonged drought; megadroughts can occur when the delicate balance between soil moisture and evaporation are upset. The most recent megadrought dates back to the late 16th century and … Continue reading New Study Warns of Southwest Megadrought

Climate Change Makes the Earth Wobble

In the year 2000, the Earth’s spin axis made a sudden turn towards the east. While some shifts in the geographical pole occur regularly and are well understood, this sudden shift required a new explanation. According to teams from UT Austin and NASA’s Jet Propulsion Laboratory (JPL), climate change is the driving force behind the north pole’s wayward path.   In 2013, the team from … Continue reading Climate Change Makes the Earth Wobble

The Hottest Year on Record

The warm winter has been hard to miss. January temperatures were higher than average, and a little over a month ago most the Northeast was turning off the heat, opening windows, and wearing shorts in December. The strange weather hasn’t been confined to the past few months. In 2015 the world saw extreme floods along the Mississippi river, a heat wave in India that killed thousands … Continue reading The Hottest Year on Record
