John Eidson, writer, analyst for energy, climate change, government policies, retired electrical engineer, independent voter: When Gov. Lamm finished his speech, the conference room was silent, as everyone in the overflow audience realized that what they’d just heard was being methodically carried out by the post-1960s Democratic Party in its ongoing attempt to “fundamentally transform the United States of America” through multiculturalism and massive immigration.
Allan Macrae, mining and geotechnical engineer: Earth may now be entering another natural cooling trend. Earth Surface Temperature warmed approximately ("~") 0.7 degrees Celsius ("C") from ~1910 to ~1945, cooled ~0.4 C from ~1945 to ~1975, warmed ~0.6 C from ~1975 to 1997, and has not warmed significantly from 1997 to 2007. CO2 emissions due to human activity rose gradually from the onset of the Industrial Revolution, reaching ~1 billion tonnes per year (expressed as carbon) by 1945, and then accelerated to ~9 billion tonnes per year by 2007. Since ~1945 when CO2 emissions accelerated, Earth experienced ~22 years of warming, and ~40 years of either cooling or absence of warming. it is appropriate to cease all CO2 abatement programs that are not cost-effective, and focus efforts on sensible energy efficiency, clean water and the abatement of real atmospheric pollution, including airborne NOx, SOx and particulate emissions. The tens of trillions of dollars contemplated for CO2 abatement should be saved or re-allocated to truly important global priorities.
Crystal R. Sanders is an associate professor of history and director of the Africana Research Center at Pennsylvania State University: The world mourns Katherine Johnson, a pioneering mathematician and scientist who became famous for performing the calculations that enabled the first American, John Glenn, to orbit the Earth. Although the blockbuster hit “Hidden Figures” made Johnson famous for her work at NASA, she also made history long before the space race with the Soviet Union as one of the first black graduate students to attend a previously all-white, tax-supported Southern university. Johnson blazed a trail in West Virginia when she desegregated West Virginia University in 1940. Johnson’s vast achievements demonstrated the intellectual capabilities of black students — black women in particular.
Guus Berkhout, physicist, electrical engineer, founder of Netherlands based Climate Intelligence Foundation (CLINTEL): Natural as well as anthropogenic factors cause warming. CO2 is plant food, the basis of all life on Earth. Global warming has not increased natural disasters. Climate policy must respect scientific and economic realities. OUR ADVICE TO THE EUROPEAN LEADERS IS THAT SCIENCE SHOULD STRIVE FOR A SIGNIFICANTLY BETTER UNDERSTANDING OF THE CLIMATE SYSTEM, WHILE POLITICS SHOULD FOCUS ON MINIMIZING POTENTIAL CLIMATE DAMAGE BY PRIORITIZING ADAPTATION STRATEGIES BASED ON PROVEN AND AFFORDABLE TECHNOLOGIES.
