The Wharf residential and business project I visited recently is probably one of the biggestThe U Street/Shaw and 14th Street area has fast been turned into an upscale neighborhood in recent years, with many new restaurants and shops opening and new apartment constructionThe area, a 90 percent black neighborhood just a few decades ago, was only 30 percent African American by 2010To Hyra, it has caused not just residential displacement for African Americans but also political and cultural displacementHe saw major issues of gentrification and segregation in Washington beneath the surface of rapid urban renewalThese changes may look pleasant, but not quite so to Derek Hyra, an associate professor at the American University School of Public Affairs and an expert on neighborhood changeThe 14th Street near U Street, a traditional African American neighborhood, is now lined up with hip restaurants and bars in this photo taken on SundayWhites are the majority now, accounting for 55 percent of the communityThe same urban renewal is happening in other parts of WashingtonThe United Nations weather agency says the past 10 years were likely the hottest decade since scientists began keeping records.In a new report, the World Meteorological Organization, or WMO, blames the rising temperatures mainly on greenhouse gases produced by human activities."Average temperatures for the five-year, 2015-to-2019 and 10-year, 2010-to-2019 periods are almost certain to be the highest on record," the WMO said.The report predicted that 2019 would become the second- or third-warmest year on record.Final temperature measurements will not be available for several months.Petteri Taalas is the Secretary-General of the WMO.He says severe heatwaves and floods that used to happen about once every hundred years have become "regular" events."Countries ranging from the Bahamas to Japan to Mozambique suffered the effect of devastating tropical cyclones.Wildfires swept through the Arctic and Australia," he noted.Taalas said that one of the main effects of climate change is the lack of predictable rainfall.This presents a threat to successful harvests and will likely create food security problems in some countries in the future, he said.The report said climate change was a main driver of a recent increase in world hunger after 10 years of decrease.It estimated that about 820 million people suffered from hunger in 2018.The WMO said that weather disasters have displaced millions of people this year and affected rainfall from India to northern Russia, to the central United States and other areas.Oceans, which take in an estimated 90 percent of the extra heat produced by greenhouse gases, are now at their highest recorded temperatures.Sea water is also 25 percent more acidic than it was 150 years ago, the report said.This is threatening ocean environments that provide food and jobs for billions of people.Levels of carbon dioxide in the atmosphere reached a record 407.8 parts per million in 2018 and continued to rise in 2019.Experts say carbon dioxide can be damaging because it can remain in the atmosphere for hundreds of years and in the ocean for even longer.On Monday, at the opening of a climate meeting in Spain, United Nations Secretary-General Antonio Guterres warned that 400 parts per million had once been considered "unthinkable.
