3 Things You Should Know About the Hottest Year Ever Recorded
We hate to sound like a broken record, but we keep breaking heat records. Any way you slice it, last year was warm. Unusually so.
National Oceanic and Atmospheric Administration (NOAA) and National Aeronautics and Space Administration (NASA) have both confirmed what scientists have been predicting for months: 2015 was globally the hottest year ever recorded (and the direct temperature records date back to 1880). But what else did scientists determine about the state of the climate in 2015? Here’s what else you need to know.
1. 2015 Crushed 2014
Not only was 2015 the warmest year on record globally, it beat the previous record, set in 2014, by a wide margin. The average temperature (over land and ocean surfaces) was 1.62 F (0.90 C) above the 20th century average, a full 0.29 F (0.16 C) above the previous record set in 2014.
That might not seem like much, but it’s the widest margin by which the global average annual temperature record has been broken—ever.
2. It Wasn’t All Due To El Niño—But It Played A Part
The planet is warming because of manmade carbon pollution and other greenhouse gases emitted from human activities like burning fossil fuels. The planet has warmed about 1.4 F (0.8 C) since 1880 and in 2015 this warming trend continued unabated.
On top of this human-caused warming, an El Niño event began last year and continues into the present. El Niño refers to the natural condition where ocean surface temperatures in the eastern and central Pacific near the Equator warm to levels above the long term average. The 2015/2016 El Niño rivals the one from 1997/1998 as the strongest since record-keeping began (in terms of ocean surface temperatures above the long-term average).
El Niño events are a result of complex circulations in the ocean and atmosphere. They occur roughly every four to seven years and have a big impact on weather patterns globally. El Niño events can cause short-term spikes in average global temperatures, but they are not behind the long-term warming we’ve experienced over the past century. An increasing body of research suggests that strong El Niño events might happen more frequently as our planet continues to warm and our climate changes.
The bottom line? El Niño makes temperatures change from year to year, but in the long run, the Earth is steadily warming and it’s due to human activity.
Climate Reality’s director of science and solutions, Ryan Towell, goes into more detail about El Niño on CCTV America’s The Heat.
3. Fifteen of the 16 Hottest Years on Record Globally Have Occurred After 2000
Of these 16 years, 1998 was the only one that occurred in the 20th century—and like 2015, 1998 was a strong El Niño year. While climate scientists don’t expect every year to be record warm (due to these natural fluctuations), there is already evidence to suggest this time next year we’ll be writing about 2016 being the new hottest year on record. The writing is on the wall: as humans continue to burn fossil fuels, our climate will change.
As atmospheric scientist Katharine Hayhoe told the Associated Press, "It's getting to the point where breaking record is the norm. It's almost unusual when we're not breaking a record."

Scientists have engineered a mutant enzyme that converts 90 percent of plastic bottles back to pristine starting materials that can then be used to produce new high-quality bottles in just hours. The discovery could revolutionize the recycling industry, which currently saves about 30 percent of PET plastics from landfills, reported Science Magazine.

Cabin fever is often associated with being cooped up on a rainy weekend or stuck inside during a winter blizzard.
In reality, though, it can actually occur anytime you feel isolated or disconnected from the outside world.
What is cabin fever?<p>In popular expressions, cabin fever is used to explain feeling bored or listless because you've been stuck inside for a few hours or days. But that's not the reality of the symptoms.</p><p>Instead, cabin fever is a series of negative emotions and distressing sensations people may face if they're isolated or feeling cut off from the world.</p><p>These feelings of isolation and loneliness are more likely in times of <a href="https://www.healthline.com/health-news/yes-covid-19-cases-are-rising-why-you-still-need-to-practice-social-distancing" target="_blank">social distancing</a>, self-quarantining during a <a href="https://www.healthline.com/health/what-is-a-pandemic" target="_blank">pandemic</a>, or sheltering in place because of severe weather.</p><p>Indeed, cabin fever can lead to a series of symptoms that can be difficult to manage without proper coping techniques.</p><p>Cabin fever isn't a recognized psychological disorder, but that doesn't mean the feelings aren't real. The distress is very real. It can make fulfilling the requirements of everyday life difficult.</p>
What are the symptoms?<p>Symptoms of cabin fever go far beyond feeling bored or "stuck" at home. They're rooted in an intense feeling of isolation and may include:</p><ul><li>restlessness</li><li>decreased motivation</li><li><a href="https://www.healthline.com/health/irritability" target="_blank">irritability</a></li><li>hopelessness</li><li><a href="https://www.healthline.com/health/unable-to-concentrate" target="_blank">difficulty concentrating</a></li><li><a href="https://www.healthline.com/health/irregular-sleep-wake-syndrome" target="_blank">irregular sleep patterns</a>, including sleepiness or sleeplessness</li><li>difficulty waking up</li><li><a href="https://www.healthline.com/health/lethargy" target="_blank">lethargy</a></li><li>distrust of people around you</li><li>lack of patience</li><li>persistent <a href="https://www.healthline.com/health/depression/depression-vs-sadness" target="_blank">sadness or depression<br></a></li></ul>
What can help you cope with cabin fever?<p>Because cabin fever isn't a recognized psychological condition, there's no standard "treatment." However, mental health professionals do recognize that the symptoms are very real.</p><p>The coping mechanism that works best for you will have a lot to do with your personal situation and the reason you're secluded in the first place.</p><p>Finding meaningful ways to engage your brain and occupy your time can help alleviate the distress and irritability that cabin fever brings.</p><p>The following ideas are a good place to start.</p>
When to get help<p>Cabin fever is often a fleeting feeling. You may feel irritable or frustrated for a few hours, but having a virtual chat with a friend or finding a task to distract your mind may help erase the frustrations you felt earlier.</p><p>Sometimes, however, the feelings may grow stronger, and no coping mechanisms may be able to successfully help you eliminate your feelings of isolation, sadness, or depression.</p><p>What's more, if your time indoors is prolonged by outside forces, like weather or extended shelter-in-place orders from your local government, feelings of <a href="https://www.healthline.com/health/anxiety" target="_blank">anxiety</a> and fear are valid.</p><p>In fact, anxiety may be at the root of some cabin fever symptoms. This may make symptoms worse.</p><p>If you feel that your symptoms are getting worse, consider reaching out to a mental health professional who can help you understand what you're experiencing. Together, you can identify ways to overcome the feelings and anxiety.</p><p>Of course, if you're in isolation or practicing social distancing, you'll need to look for alternative means for seeing a mental health expert.</p><p>Telehealth options may be available to connect you with your therapist if you already have one. If you don't, reach out to your doctor for recommendations about mental health specialists who can connect with you online.</p><p>If you don't want to talk to a therapist, <a href="https://www.healthline.com/health/depression/top-iphone-android-apps" target="_blank">smartphone apps for depression</a> may provide a complementary option for addressing your cabin fever symptoms.</p>
The bottom line<p>Isolation isn't a natural state for many people. We are, for the most part, social animals. We enjoy each other's company. That's what can make staying at home for extended periods of time difficult.</p><p>However, whether you're sheltering at home to avoid dangerous weather conditions or heeding the guidelines to help minimize the spread of a disease, staying at home is often an important thing we must do for ourselves and our communities.</p><p>If and when it's necessary, finding ways to engage your brain and occupy your time may help bat back cabin fever and the feelings of isolation and restlessness that often accompany it.</p>
