It’s too bad that your magazine is publishing articles written by left-wing environmentalists (likely devoid of any science background) making statements like “the very real effects of climate change” (see “The Last Straw” about Lake Mead on 4/27 p. 20). Why are individuals like this writing for an engineering- and construction-related journal when the climate-changers are killing construction projects all over the world?
