The 2010s amounted to "a decade lost" for slowing climate change, as nations around the world failed to substantially rein-in the heat-trapping emissions generated by power plants, factories, cars and trucks, and other sources that burn fossil fuels, a United Nations report said Tuesday.
The Earth's average temperature is now on track to soar by close to 4 degrees Celsius – or 7.2 degrees Fahrenheit – by the end of the century compared to pre-industrial levels. Scientists have broadly concluded that the planet needs to keep warming to within 2 degrees Celsius, or 3.6 degrees Fahrenheit, to avoid the most catastrophic impacts of climate change.
Rapid rates of warming, meanwhile, are already essentially locked-in: Even ambitious new efforts to slash carbon emissions, as represented in nations' commitments under the 2015 Paris climate accord, will still produce 2.9 to 3.4 degrees of warming.
The report, from the UN's World Meteorological Organization, renewed calls for yet more urgent action to drastically reduce emissions around the world.
"There is no sign of a slowdown, let alone a decline, in greenhouse gases concentration in the atmosphere despite all the commitments under the Paris Agreement on Climate Change," WMO Secretary-General Petteri Taalas said in a statement. "We need to translate the commitments into action and increase the level of ambition for the sake of the future welfare of mankind."
Despite rapid growth in renewable energy sources such as wind and solar, sharp declines in coal-fired power generation in developed nations, and recent high-profile investments in electric vehicles and EV charging infrastructure, global emissions are next expected to peak by the end of the next decade.
"The effects of climate policies have been too small to offset the impact of key drivers of emissions such as economic growth and population growth," the report said, characterizing the finding as a "rather bleak fact."
Already, the amount of carbon dioxide in the atmosphere is comparable to 3-5 million years ago, when temperatures were roughly 2-3 degrees warmer and sea levels were 30-60 feet higher, the WMO said.
"In this critical period, the world must deliver concrete, stepped-up action on emissions," Inger Andersen, executive director of the UN Environment Programme said in a statement. "We face a stark choice: set in motion the radical transformations we need now, or face the consequences of a planet radically altered by climate change."
The United Nations High Commissioner for Refugees (UNHCR) has reported that an estimated one million people have fled from Ukraine since Russia invaded. Christopher Boian, senior communications officer at UNHCR, joined Cheddar News to report on the current refugee crisis and what the world might expect if conditions continue to worsen. "We have planning figures that forecast as many as four million people could be forced to flee Ukraine," he said. "But that very much depends on how the conflict underway in that country at the moment unfolds in the days and possibly weeks ahead."
Under the U.S. Renewable Fuel Standard (RFS), corn-based ethanol has been mixed into gasoline sold at pumps in the U.S. since 2005, when a policy was enacted aimed at reducing emissions. Corn-based ethanol had been thought to be a relatively greener energy source compared to other biofuels, but now, a new study published in the Proceedings of the National Academy of Sciences reports it may be actually worse for the climate than straight gasoline. Tyler Lark, an assistant scientist at the University of Wisconsin-Madison's Center for Sustainability, joined Cheddar News' Closing Bell and discussed the pushback against the study. "Essentially when you need to produce more corn to meet the demand for use as ethanol as fuel, farmers respond and they switch more crops like soybeans and wheat into corn," Lark said. "They also bring more land into production, so things that used to be pasture grassland, and both those activities are associated with increased greenhouse gas emissions."
