The significant improvements in air and water quality due to coronavirus lockdowns reducing pollution have led to calls for a low-carbon future. However, the urgency to get millions back to work is complicating the environmental situation. As economies worldwide have closed down, wildlife has been observed returning to urban areas, with wolves, deer, and kangaroos seen on normally busy streets. Fish have been spotted in Venice canals that are no longer contaminated by motor boats, and residents in some Indian cities have reported seeing the Himalayas for the first time in years. Satellite images have revealed substantial improvements in air quality across Europe and Asia, including China, where the outbreak of the coronavirus originated. Yet, residents in some of China's most pollution-prone cities are concerned that the clear skies may not last once the world's second-largest economy resumes operations. Tang Zhiwei, a 27-year-old resident of Shanghai, mentioned that as the epidemic eases in the second half of the year and factories reopen, the weather will gradually worsen. He advised people to appreciate the blue sky while they can. Greta Thunberg emphasized that addressing the coronavirus does not mean the climate crisis has disappeared, urging action on both fronts simultaneously. UN chief Antonio Guterres called on governments to use their economic responses to the pandemic to also address the urgent issue of climate change on Earth Day. Amid a global divide between supporters of environmentally friendly stimulus measures and industry lobbyists pushing to relax climate regulations, Guterres advised governments against rescuing heavily polluting industries. Guterres emphasized the urgency of addressing the planet's environmental crisis on Earth Day, alongside the focus on the COVID-19 pandemic. According to Peter Betts, a former climate negotiator for Britain and the EU, there is now a push for economic stimulus packages in response to the coronavirus to prioritize low-carbon, climate-conscious measures. Betts warned that some governments may prioritize jumpstarting the economy and creating jobs over environmental concerns. US President Donald Trump considers it a top priority to revitalize America's oil and gas industry, ensuring jobs and financial stability for these important companies. Last year was the hottest on record in Europe, with rising environmental concerns due to increased levels of greenhouse gases in the atmosphere. C3S director Carlo Buontempo stated to Reuters that the warming trend is now undeniable worldwide, leading to an increase in the frequency of record-breaking events. The head of the World Meteorological Organization (WMO) predicted a 6% decrease in carbon dioxide emissions due to the coronavirus pandemic, the largest drop since World War Two. However, the WMO emphasized that this reduction will not halt climate change, stating that while COVID-19 may temporarily lower greenhouse gas emissions, it is not a replacement for ongoing climate action. Due to millions of people staying at home, air quality in China has gotten better. Emissions in Shanghai decreased by almost 20% in the first quarter, and in Wuhan, where the pandemic started, monthly averages dropped by over a third. However, experts are concerned that this decrease could lead China to ignore pollution in order to boost the economy, which experienced its first decline in the first quarter.
