Halloween Horror Story: 5 Scariest Aspects of Climate Change

By Casey Ivanovich

Halloween has arrived, and it's time once again for goblins, gremlins and ghost stories.

But there's another threat brewing that's much more frightening—because it's real.


An unrecognizable world is quickly creeping up on us as climate change progresses—and the anticipated impacts are enough to rattle anyone's skeleton.

Here are five of the scariest aspects of climate change. Read on if you dare…

1. Extreme Weather is Becoming More Extreme

A changing climate paves the way for extreme weather events to live up to their name.

In 2017 alone we saw fatal events worldwide, including:

The fingerprints of climate change can be found on each of these events.

As global temperatures continue to rise, heat waves are expected to become more intense, frequent and longer lasting.

Scientists also predict that rainfall patterns will continue to shift, increasing regional risk for widespread drought and flooding.

Drought conditions may also prompt wildfires to occur more frequently and within a longer fire season. The wildfire season in the western U.S. is already weeks longer than in previous years.

Hurricanes are also influenced by climate change. Rising sea surface temperatures, a moister atmosphere and changing atmospheric circulation patterns have the potential to increase hurricanes' power and travel paths.

Extreme weather intensification impacts human health and development in many ways—extreme heat events directly generate health hazards such as heat stroke, while drought and wildfires threaten crop and ecosystem stability.

The 2017 hurricane season has already demonstrated the shocking consequences of intensified hurricanes and flooding, with Hurricanes Harvey, Irma and Maria killing more than 150 people and causing as much as $300 billion in damages in the U.S. alone.

2. Tipping Points Loom in Near Future

A particularly alarming facet of climate change is the threat of irreversible changes to climate conditions, called "tipping elements."

These components of the climate system earn their title from a possession of critical thresholds, or "tipping points," beyond which a tiny change can dramatically alter the state of the system.

Many tipping elements have been identified by scientists and some may have already passed their critical threshold. For example, a vicious cycle of sea ice melt has already been triggered, leading scientists to predict that Arctic summers will be ice-free before mid-century.

Imminent tipping points also exist for melting ice sheets, particularly those of Greenland and West Antarctica, where full ice sheet collapse could result in global sea level rise of up to 20 feet and 16 feet respectively.

Coral reefs too are rapidly approaching a grave tipping point. Essential relationships between algae and corals begin to break down as ocean waters rise in temperature and acidity. Without stabilizing these changes, the majority of global reef systems may collapse before global temperatures reach a two-degree Celsuis warming threshold.

3. Coastal Communities Battle Sea Level Rise

Sea level rise is one of the most visible impacts of climate change, as increased coastal erosion physically erases continental borders.

As the climate warms, ocean waters expand and ice sheets and glaciers melt. Both factors contribute to a rising sea level at an accelerating rate. Communities in Alaska and several Pacific Islands are already fleeing rising seas—relocating as their villages are engulfed and eroded.

Rising sea levels also intensify damages from extreme weather events such as hurricanes. A higher sea level allows storm surges to grow in height and volume, exacerbating flooding and associated damages.

As water levels continue to rise, more coastal communities will feel the consequences. Many major cities are located on coastlines, with almost 40 percent of U.S. citizens living in coastal cities.

Protecting people from this creeping threat will be difficult and costly—as we've already seen in the aftermath of coastal storms such as Superstorm Sandy.

4. Humans Are Nearing Uncharted Climate Territory

A globally averaged two-degree Celsius (or 3.6 degrees Fahrenheit) of warming over preindustrial levels is the most widely suggested threshold we need to stay "well" below.

The threshold was first proposed by William Nordhaus in the 1970's, in part because of its historical significance—the human species has never lived during a time in which global temperatures were equivalent to two-degrees Celsius above preindustrial levels.

The unprecedented nature of this benchmark provided a foundation for alarm that carried the two-degrees Celsius value into political and scientific discussions for decades.

In a changing climate, unprecedented events will become the norm.

In some cases, they already have.

As infectious diseases spread to previously untouched regions and an Arctic ozone hole threatens to open, people are beginning to catch the first glimpses of the new world we are creating—one that is in many ways more hostile and dangerous than the one we leave behind.

5. Many American Politicians Deny the Problem

Perhaps the only thing more terrifying than the impacts of climate change is the overwhelming denial of their existence by some political leaders in the U.S.

The Paris agreement served as a major step forward in promoting climate change mitigation policy on an international scale, with almost every nation agreeing to tackle this looming threat.

Then in June, President Trump announced his intent to withdraw from the agreement. That means the U.S. will be one of only two countries—out of almost 200—failing to participate in the accords.

The same efforts towards dismantling U.S. climate progress can be seen in recent national policy. U.S. Environmental Protection Agency Administrator Scott Pruitt (who recently claimed that carbon dioxide is not a major contributor to global warming) is perhaps the most visible of an exhausting list of leaders within the current administration who deny climate science. The administration is trying to undermine or reverse policies addressing climate change, including the Clean Power Plan and information about climate change is vanishing from official agency websites.

The rest of the globe is striving to implement meaningful climate policy, including China's unparalleled growth in renewable energy support. Soon the U.S. will be left in the dust in the race for a greener world.

Be afraid. Be very afraid. Then do something about it.

We can't protect you from the monsters hiding under your bed. But combating the ominous impacts of climate change is a much more hopeful endeavor.

The Past 5 Years Were the Arctic's Warmest on Record

The Arctic is still warming at twice the rate of anywhere else on Earth, and the region's air temperatures in the past five years between 2014-2018 have exceeded all previous records since 1900, according to a peer-reviewed report released by the U.S. National Oceanographic and Atmospheric Administration (NOAA) on Tuesday.

The agency's 13th annual Arctic Report Card also concluded that 2018 was second only to 2016 in terms of the region's overall warmth.

3 Key Dangers of Solar Geoengineering and Why Some Critics Urge a Global Ban

By Justin Mikulka

A Harvard research team recently announced plans to perform early tests to shoot sunlight-reflecting particles into the high atmosphere to slow or reverse global warming.

These research efforts, which could take shape as soon as the first half of 2019, fall under the banner of a geoengineering technology known as solar radiation management, which is sometimes called "sun dimming."

Report: Current Climate Policies Will Warm the World by 3.3˚C

This past October, a widely disseminated United Nations report warned that far-reaching and significant climate impacts will already occur at 1.5˚C of warming by 2100.

But in a study released Tuesday, researchers determined that the current climate polices of governments around the world will push Earth towards 3.3˚C of warming. That's more than two times the aspirational 1.5˚C target adopted by nearly 200 nations under the 2015 Paris agreement.

The Lesson From a Burning Paris: We Can’t Tax Our Way Out of the Climate Crisis

By Wenonah Hauter

The images from the streets of Paris over the past weeks are stark and poignant: thousands of angry protesters, largely representing the struggling French working class, resorting to mass civil unrest to express fear and frustration over a proposed new gas tax. For the moment, the protests have been successful. French President Emmanuel Macron backed off the new tax proposal, at least for six months. The popular uprising won, seemingly at the expense of the global fight against climate change and the future wellbeing of our planet.
