My grandmother was a worrier. 

Even she, however, would have had a hard time worrying about other major challenges, problems and threats during the worst of the COVID-19 pandemic.

That, it turns out, was also true for the world during COVID when it came to discussions about the threat from climate change.

In a recent study published in the prestigious journal Proceedings of the National Academy of Sciences, Oleg Smirnov, associate professor in the Department of Political Science at Stony Brook University, examined the level of concern on Twitter about climate change during 2020 and 2021 and compared those numbers to 2019, the last year before COVID.

According to the pool of finite worry, which Princeton professor of Psychology Elke Weber developed, environmental and climate concerns decline amid worries about other major threats.

Smirnov found that the total number of tweets that mention climate change dropped to 5.6 million in 2020 and 5.3 million in 2021, from 8 million in 2019. This, Smirnov points out, occurred despite an increase in Twitter users, more climate disasters and more climate news in 2021.

“The psychological foundation tell us that people may only really respond to one threat at a time,” Smirnov said in an interview. The anxiety and the reaction to that threat may be limited because it requires major energy.

“Maybe, for biological reasons, [people] put all their energy into responding to the most immediate threat,” Smirnov added.

By tracking daily tweets and various measures of COVID cases, Smirnov found on a finer scale as well that discussions of climate change diminished amid higher infections and mortality.

For every thousand new COVID-19 cases in the United States, climate change tweets decreased by about 40.5 tweets per day. Every thousand new deaths resulted in 3,308 fewer climate tweets.

While Smirnov understood the need to focus on the pandemic, he suggested a lack of concern about climate change could disrupt efforts to protect the planet

“This has profound implications,” Smirnov said. “Without a focus on climate change, without an emphasis on its importance, there is less urgency and less pressure on politicians to do something about it.”

Even in better times, climate change efforts are “fragile,” he said, which adds to the uncertainty about the ability to address the challenge adequately.

Indeed, even the sentiment analysis, in which Smirnov reviewed the emotional content of words used to describe climate change and the threat to the planet and humanity, became less negative during the worst of the pandemic.

When asked about the possibility that climate change concerns might have declined during COVID in part because the carbon footprint declined amid travel restrictions and slowdowns in industrial production, Smirnov likened such an approach to short-term fasting or extreme dieting.

While spending a few days on these extreme diets can reduce a person’s weight over the course of days, such an approach provides “no substantial improvement in your health” longer term, he said.

So, what about now, as concerns about the pandemic abate, people have stopped wearing masks and schools and stadiums are full?

Smirnov plans to continue to collect Twitter data for the remainder of this year, to see whether a return to normalcy brings the focus back to the threat from climate change.

As for his own experience, Smirnov recognized that climate change took a back burner amid the worst of the pandemic.

“My attention certainly was hijacked by COVID-19, despite the fact that climate change is part of my work,” Smirnov said. In April of 2020, Smirnov recalled worrying about where his family would find food instead of thinking about greenhouse gases and rising sea levels.

In the present, Smirnov remains concerned about the kind of tipping points and climate inertia that threatens the future.

Ever the worrier, my grandmother might be relieved enough by the less virulent form of the virus and the availability of vaccines and treatment to return to worrying about the threat climate change poses.

Drought and the potential increase in the number of droughts worldwide due to climate change remains a concern for scientists. A recent study led by Stony Brook University researchers suggests that human migration due to droughts will increase by at least 200 percent as we move through the 21st Century. Based on a series of both climate and social science modeling systems and other social science data, the study findings imply that migration may force the need to adjust sociopolitical policies to offset widespread human displacement in the future. The study is published in International Migration Review.

According to lead author Oleg Smirnov, PhD, Associate Professor in the Department of Political Science at Stony Brook University, the research team worked from an ensemble of 16 climate models to generate drought projections for rest of the 21st Century. They centered on two greenhouse gas emissions scenarios: an optimistic one consistent with the Paris Agreement, and a pessimistic one based on current use of energy and greenhouse gas emissions.

It is important to note that while the Groundswell report assesses human migration projections due to climate change by 2050 in six world regions, this study analyzes potential drought-induced human migration around the entire world for the whole century going forward.

Both Smirnov and co-author Gallya Lahav, PhD, a migration specialist and Associate Professor of Political Science at Stony Brook University, assessed the sociopolitical climates and policies in connection with the climate models. Co-authors and climate experts Minghua Zhang, PhD, of Stony Brook University’s School of Marine and Atmospheric Sciences (SoMAS), and Tingyin Xiao of Princeton University, generated global drought projections for two emissions scenarios for the period of 2008 to 2100 in order to complete the analysis.

Overall, they project there will be a massive increase in drought-induced migration in the coming years – 200 percent more based on the optimistic climate projections and as high as 500 percent more if world leaders fail to cooperate on climate change mitigation measures.

“One interesting finding is that we also identified a large group of people who will want to migrate but fail to do so as droughts cover large areas of land making possible destinations difficult to get to or inferior to their land of origin,” explains Smirnov.

The authors estimate that this segment of “immobile” people will also increase by about 200 percent in the optimistic scenario, yet almost 600 percent under the “business as usual” or pessimistic scenario.

“Our models make us not only concerned about the increasing number of environmentally displaced people that may spread across the globe, but we are equally, if not more, concerned about the large number of these ‘immobile’ persons – who may be desperate to leave but unable to do so, which may contribute to social suffering and instability,” emphasizes Smirnov.

Furthermore, “given that environmentally-induced migrants largely fall outside of international legal frameworks like the Refugee Convention which protects those fleeing war or conflict, a multi-lateral holistic policy approach is vital in this grey area,” adds, Lahav, a previous consultant to the United Nations Population Division.

Despite the scientific quest to systematically assess and predict future migratory outcomes, the researchers agree that the social science aspect of the study may have additional unknown variables and complexities when projecting because of the political aspects of migration. The authors write “we can only talk about potential migration pressures, as opposed to actual migration, since we do not know how future political responses will affect and potentially constrain future migration flows. Similarly, we do not rely on the absolute number of migrants, since these numbers are sensitive to the arbitrary modeling assumptions.”

As the researchers chart the drought-induced migration models toward the end of the 21st Century, they warn that many countries will have large numbers of migrating peoples. They state that the largest number of people displaced by drought under unmitigated change would occur in these countries: Nigeria, Egypt, China, Turkey, Algeria, Mexico, Morocco, and Venezuela. The projected largest number of immobile persons would be those in Turkey, Mexico, Morocco, Algeria, Brazil, Mali, and China.

Overall, say Smirnov and colleagues, the study findings provide solid evidence that global climate change mitigation would be less costly in terms of human suffering and economic loss from drought-induced migration than policies designed to deal with the overwhelming challenges of unmitigated climate change.

The general consensus among those who study the evaporating future of the global water supply is to blame population growth. However, a recent study out of Stony Brook University suggests climate change may be the dominant catalyst for future exposure to drought.

The number of people exposed to extreme drought would see a 426.6 percent increase by 2100 at the current rates of greenhouse gas emissions and population growth 

A team of scholars used 16 climate models and United Nation population growth projections to ensure a more accurate prediction. The study reported that the number of people exposed to extreme drought would see a 426.6 percent increase by 2100 at the current rates of greenhouse gas emissions and population growth. While many might agree that water scarcity will become increasingly more problematic in the future — especially if preventative actions don’t amp up fast — there is a difference between what each party suggests is the best approach: to focus on slowing population increases with socioeconomic development or to cut the rate of greenhouse gas emissions. This study states the latter may be the most efficient way to avoid widespread drought.

Their predictions attribute 59.5 percent of future drought to climate change and only 9.2 percent of the increase to population growth. The remaining 31.4 percent accounts for the combined effect of these two factors. According to Stony Brook University’s professor Oleg Smirnov, who was involved in conducting the study, the “results imply that top greenhouse gas-emitters have the greatest capacity to decrease future exposure to extreme drought.”

Though climate change mitigation policies may have the power to most effectively reduce the future effects of widespread drought, population growth is still an important factor to consider. “Population growth alone is responsible for over 35 million more people exposed to extreme drought globally per month by the end of the century,” Smirnov said. “However, we also found that, for the same period, climate change is responsible for about 230 million more people exposed to extreme drought.”

The conclusion that Smirnov and his team have come to portrays climate change as playing a more important role than population increase. However, each country is affected differently by each factor, so the solution is not as simple as just cutting emissions. The worst-case scenario would be to continue at the present rate of both greenhouse gas emissions and population growth. Regardless of which factor ranks in terms of importance, this study and many others like it suggest the same message: if we are to counter the effects of future global drought exposure, we need to act as soon as possible.
