Climate Change Is Making Animals Smaller
Think little. It will have its advantages in the future. Researchers predict that climate change will cause animals to lose 25 percent of their size as small, quick animals that are able to adapt to many environments will thrive over the next 100 years, according to a new study from the University of Southampton and published in the journal Nature Communications.
The researchers found that animals rest and eat less in extreme heat, which often stunts growth. And when small size means adaptability and survival, future generations will get smaller to meet their conditions. The research team also has some dire predictions for big animals with long life spans. Over the next century nearly 1,000 species will go extinct. These less adaptable animals often require unique environmental conditions and will not be able to withstand climate change and habitat loss. Eagles, tigers and rhinoceroses are particularly vulnerable species, according to a university press release.
"It is worrying that we are losing these big species when we don't know their full role," said Rob Cooke, lead author of the study, to The Guardian. "Without them, things could begin to degrade quite quickly. Ecosystems could start to collapse and become not what we need to survive."
The extinction of so many species will have a ripple effect as it affects ecosystems that humans rely on for food and clean water. Many large mammals disperse seeds, for example. Sure enough, humans are to blame for the impending catastrophe.
"By far the biggest threat to birds and mammals is humankind – with habitats being destroyed due to our impact on the planet, such as deforestation, hunting, intensive farming, urbanization and the effects of global warming," said Cooke in a university press release.
To perform the study, the researchers looked at 15,484 land mammals and birds. They homed in on five traits: size, how many offspring they had, breadth of habitat, diet and length of time between generations. Cooke and his team combined this data with the the International Union for Conservation of Nature's Red List of Threatened Species to determine which animals are most likely to become extinct in the next century.
"If all these extinctions [of larger animals] take place, we are fundamentally restructuring life on this planet," said Cooke to The Guardian.
While the future is bleak for large animals, it's bright for small, fast-lived, highly fertile, insect-eating animals, which can thrive in a wide-variety of habitats, like rodents and songbirds, according to the study's findings.
The researchers see their work as an opportunity for conservationists to protect species at risk. "Extinctions were previously viewed as tragic, deterministic inevitabilities, but they can also be seen as opportunities for targeted conservation actions," said Amanda Bates, Research Chair at Memorial University in Canada and one of the study's authors in a university press release. "As long as a species that is projected to become extinct persists, there is time for conservation action and we hope research such as ours can help guide this."

The climate crisis is set to be a significant factor in a U.S. presidential election for the first time, with new polling showing a clear majority of American voters want decisive action to deal with the threats posed by global heating.

Hamstrung by coronavirus lockdowns, frustrated school strikers have spent months staging digital protests against world leaders failing to act urgently on climate change.
Pandemic Stalls Protests<p>Last November, the head of the UN Environment Program was among the public and scientific figures to warn that 2020 offered a last chance to cut emissions. Then, few could have suspected this deadline would coincide with an unprecedented public health emergency.</p><p>The pandemic has <a href="https://www.dw.com/en/tough-times-ahead-for-climate-protesters-during-corona-pandemic/a-52978469" target="_blank">dealt climate activism a blow</a>. Niedeggen says that as a movement demanding that the world act on scientific advice, the school strikers took lockdown restrictions extremely seriously, halted public protests immediately and took their activism online.</p><p>On April 24, Fridays for Future organized a "digital strike," with Niedeggen hosting a that racked up close to a quarter of a million views. "We were not physically standing together, but we were all fighting together," she says.</p><p><a href="https://www.dw.com/en/climate-strikers-get-inventive-during-the-covid-19-crisis-fridays-for-future/a-53229262" target="_blank" rel="noopener noreferrer">Activists also gathered thousands of placards</a> from across Germany to lay out in front of the German Bundestag around the central slogan: "Fight every crisis."</p>
Opportunity for a New Normal<p>Last September's Global Climate Strike drew young and old protestors around the world, with organizers estimating a global turnout of 7.6 million, including an estimated 270,000 people in Berlin. Activists have adjusted this year's event to account for social distancing and different levels of coronavirus restrictions in cities taking part.</p><p>They say COVID-19 also presents opportunities.</p><p>"The pandemic shows that we can change our normal daily life, and we are very able to adjust to a situation of crisis," she says. The key question is how economies get back on their feet: "We have the possibility to build a new normal, to build a renewable world order, and an environmentally just, climate-just normal for everybody."</p><p>In July, Jeng was among 20 female Fridays for Future activists from the Global South to sign an open letter to G20 finance ministers warning that their decisions in "exclusive backrooms" over stimulus packages and corporate bailouts would "lock in development pathways for decades."</p><p>"The system is not broken, it was built to be unjust. We don't need recovery, we need a reboot," the letter reads, stressing that "black people, indigenous peoples and people of color," have been disproportionately hit by the economic, climate and coronavirus crises. </p>
Policy 'Not Quite There Yet'<p>Figures on stimulus spending do not suggest their words had much impact. The ministers were criticized for failing to relieve the debt of poorer countries, and according to <a href="https://www.energypolicytracker.org/region/g20/" target="_blank" rel="noopener noreferrer">Energy Policy Tracker</a>, G20 countries by August had pledged $169 billion (142 billion euros) to fossil fuels since the beginning of the pandemic.</p><p>Katrin Uba, associate professor of political science at Uppsala University in Sweden, is researching Fridays for Future. She says that despite the movement raising awareness and gaining access to policymakers, real policy change "is not there yet."</p><p>Still, she stresses that social movements go through waves of mobilization as public attention on their core issues ebbs and flows. And perhaps one of Fridays for Future's biggest achievements is birthing a politically active generation that will keep the fight up long after corona becomes a memory. </p><p>"We know clearly from our research that many of the people who came to the streets hadn't done any protesting before in their lives," she told DW. "And we also know that if you do one protest, you are likely to do more."</p>
