CLIMATE CRISIS REPORT

We now have the clearest picture yet of how different the world is today as a result of human-driven climate change. The most comprehensive report to date on the physical science of climate change was published today by the United Nations Intergovernmental Panel on Climate Change (IPCC). "Climate change is a problem that is here now. Nobody’s safe, and it’s getting worse faster,” Inger Andersen, executive director of the United Nations Environment Program, said in a press conference today. “We must treat climate change as an immediate threat.”

Extreme events — from floods to heatwaves and droughts — have gotten worse, the report says in a nutshell. And scientists are even more certain than they were before that humans’ greenhouse gas emissions, including carbon dioxide and methane (which makes up a majority of “natural gas”), are to blame. 

“We’ve known for decades that the world is warming, but this report tells us that recent changes in the climate are widespread, rapid, intensifying, and unprecedented in thousands of years,” Ko Barrett, vice chair of the IPCC, said in an August 8th press briefing. “It is indisputable that human activities are causing climate change.”
The IPCC is considered a leading authority on climate science, and its new report has more than 230 authors from 66 countries around the world. Today’s findings are an update to a similar report in 2013, and they incorporate the body of research that’s been published in scientific journals since then.

Researchers have gotten a lot better at judging how much climate change affects individual weather events since 2013, which makes a big difference this time around. For example: in July, a record-smashing heatwave in the US Pacific Northwest and Southwest Canada buckled roads and killed hundreds of people. In less than two weeks, an international team of researchers was able to determine that the extreme heat would have been “virtually impossible” without climate change.

Nearly every region of the world outside of polar regions have seen an uptick in extreme heat events since the 1950s, according to the new IPCC report. Across the globe, extreme heatwaves now occur five times more frequently than they did between 1850 and 1900 (a baseline often referred to as the preindustrial period), according to the report. Heat also exacerbates drought in some regions of the world. Droughts that previously only occurred once every decade are now 70 percent more frequent than they were in the preindustrial era.

The consequences of the climate crisis, however, are diverse and far-reaching. Severe storms and floods are another growing problem. What were previously once-in-a-decade downpours are happening 30 percent more frequently today. When it comes to tropical cyclones, there’s a greater proportion of major storms (ranked a category 3 or higher), meaning hurricanes and typhoons have grown stronger.

“Extreme weather is occurring with more frequency across the entire planet,” Paola Andrea Arias Gómez, one of the authors of the IPCC report, said during the press briefing. “We now can attribute that these changes are mainly driven by human activity.”

More bad news: without drastic action to curb the use of fossil fuels, things will get worse. Leading climate experts have set a target of limiting global warming to no more than 1.5 degrees Celsius above preindustrial levels, in order to avoid some of the worst-case scenarios that climate change could create. We’ve already reached 1.1 degrees Celsius of warming, and the report says we could reach or even surpass that dreaded 1.5 degree threshold within the next couple of decades.

What does that mean for extreme weather? Get ready for more “unprecedented” events — basically, things that have never happened before. The report authors outline five ways this is expected to happen in the future: extreme events will be even more extreme. They’ll be more frequent. There’s a greater chance of extreme events happening back to back or even different kinds of disasters happening at the same time. They’ll happen in places that surprise us. And the timing of these catastrophes will be unpredictable.

There are all sorts of other problems detailed in the new report, including vanishing ice, rising sea levels, and scary tipping points that could accelerate the pace of the climate crisis. 

There are also two more key reports expected to be published by the IPCC early next year: one that details how all of these changes to the planet will affect human life as we know it and another one that outlines potential solutions. Notably, today’s report is the only one that will be ready in time for the upcoming United Nations climate conference in November when world leaders are expected to discuss ratcheting up commitments to rein in their planet-heating pollution.

“This report is a reality check,” Valérie Masson-Delmotte, co-chair of the IPCC working group responsible for the report, said in a press release. “We now have a much clearer picture of the past, present and future climate, which is essential for understanding where we are headed, what can be done, and how we can prepare.”

How Covid has affected the world

The year 2020 was defined by the coronavirus pandemic, arguably the worst pandemic the world has seen in 100 years. COVID-19 has caused more than 75 million cases and 1.6 million deaths worldwide as of mid-December. The illness has affected nearly every aspect of life, from work and school to everyday activities like getting groceries, and even our wardrobes. Here are just some of the ways COVID-19 changed the world in 2020.

New vocabulary:   Flattening the curve refers to community isolation measures that keep the daily number of disease cases at a manageable level for medical providers. A number of new words and phrases entered the general lexicon in 2020. We were told we need to "social distance," or stay six feet apart, so that we could "flatten the curve," or slow the disease's spread in order to reduce the burden on the healthcare system. People even became familiar with relatively obscure epidemiological terms like the "basic reproduction number" (R0, pronounced R-nought), or the average number of people who catch the virus from a single infected person. And of course the name of the illness itself, COVID-19, is a new term, with the World Health Organization officially naming the disease on Feb. 11.

Wardrobe addition (Cloth face masks):  The must-have fashion item of 2020 was a small piece of cloth to put around your face. With medical masks in short supply at the beginning of the year, sewing enthusiasts began churning out homemade masks for their communities. Then, clothing companies and retailers got on board, adding masks to their fashion lines. Now, in many parts of the world, you can't leave your house without putting on a mask. At first, it was unclear whether wearing cloth masks would protect against COVID-19, but as the year went on, numerous studies showed the benefits of wearing masks, for both the wearer and those around them.

Anxiety and depression: The pandemic took a serious toll on people's mental health in 2020. One study published in August by the Centers for Disease Control and Prevention (CDC) found that levels of anxiety, depression and suicidal thoughts skyrocketed amid the pandemic. The study could not determine the reason for the rise in mental health conditions, but factors relating to the pandemic, such as social isolation, school and university closures, unemployment and other financial worries, as well as the threat of the disease itself, may play a role, the authors said. Pandemic drinking Another insidious side effect of the pandemic was increases in alcohol consumption. A study published in October in the journal JAMA Network Open found that alcohol consumption in the United States rose 14% during pandemic shutdowns. Women in particular reported worrying increases in heavy drinking during the spring of 2020, according to the study. "In addition to a range of negative physical health associations, excessive alcohol use may lead to or worsen existing mental health problems," the authors concluded.

New normal: As businesses began to open after initial lockdowns, people needed to adjust to a new normal to reduce the risk of spreading the disease from everyday activities. Businesses implemented universal mask policies. Dining switched to outdoors only. Waiting rooms became a thing of the past. You needed a reservation to go to the gym. And large gatherings and events were banned completely in many areas. Although there is no way to ensure zero risk of catching COVID-19, officials said taking precautions could reduce the risk of spread. However, as the fall began, many areas went into lockdown again amid surging COVID-19 cases.

Rampant rumors:   From the idea that drinking bleach can kill the norovirus to a theory that the virus was created in a lab as a bioweapon, the COVID-19 pandemic has generated a flurry of misinformation. Indeed, one study, published Aug. 10 in the American Journal of Tropical Medicine and Hygiene, found that the pandemic has hatched more than 2,000 rumors, conspiracy theories and reports of discrimination. Such false information can have serious consequences — the researchers of the new study found that COVID-19 related rumors were linked to thousands of hospitalizations and hundreds of deaths. "Health agencies must track misinformation associated with ... COVID-19 in real time, and engage local communities and government stakeholders to debunk misinformation," the authors concluded.

Pandemic puppies: With orders to stay at home as much as possible, many people decided to get a furry friend during quarantine. The coronavirus pandemic has been a boon for pet adoptions, particularly dog adoptions. Many shelters, breeders and pet stores reported a surge in applications for dogs, with the demand far exceeding supply, according to The Washington Post. Some shelters reported double the number of adoptions compared with the previous year, and needed to resort to waitlists to handle the demand. Not only is this good news for pets who need homes, but also for their humans, given that many studies show there are mental health benefits to pet ownership, according to NPR.

School closures: Children seem to be largely spared from the most severe effects of COVID-19, but they can still act as spreaders of the disease. So many schools across the U.S. and the world made the decision to close in 2020, and opt for virtual learning instead. Questions around how long to remain closed and how to safely reopen were the subject of much debate. As fall arrived with a number of schools still closed, many children seemed to be falling behind in learning. Statewide polls have found that nearly 9 in 10 parents are worried about their children falling behind at school due to the pandemic closures, according to The Educational Trust.

  Lowered emissions: Coronavirus lockdowns, which slowed the normal hustle and bustle of cities to a near halt, also appeared to dramatically lower emissions of carbon dioxide around the world. A study published May 19 in the journal Nature Climate Change found that daily global carbon dioxide emissions dropped by 17% in early 2020, compared with levels in 2019. That appears to be one of the biggest drops in recorded history. But this temporary drop is far from enough to undo the harmful effects of man-made climate change. "Although this is likely to lead to the largest cut in emissions since World War II, it will make barely a dent in the ongoing build-up of carbon dioxide in the atmosphere," Richard Betts, Head of Climate Impacts Research at the Met Office Hadley Centre in England, said in a statement.

New vaccine: Developing a new vaccine normally takes years to decades. But in an unprecedented feat, researchers in the U.S. and several other countries created a coronavirus vaccine — taking it from lab bench to bedside — in just under 12 months. When 2020 began, COVID-19 and the virus that causes it, SARS-CoV-2, were unknown to science. But once the virus was identified, scientists acted quickly to begin developing a vaccine. By mid-March, early trials in humans had begun, and by late summer, the vaccines were ready for more advanced trials with thousands of participants. In December, the United States authorized two COVID-19 vaccines, from Pfizer and Moderna, after trials showed impressive results. Both vaccines used molecules known as mRNA to stimulate an immune response against the coronavirus, marking the first time that any mRNA vaccine has been authorized for use in people. The vaccines were heralded as an extraordinary scientific advancement, and the first doses were administered to healthcare workers in the U.S. in mid-December.

All we can do now is hope that we have learned the lessons of Covid 19 well ... and we will be adequately prepared for the next pandemic. And there will be another pandemic.
