Climate change has contributed to droughts since 1900, and is likely to get worse, says tree-ring study Using studies of tree rings going back centuries, scientists have unearthed clear evidence that the rise of human-generated greenhouse gases was having an effect on global drought conditions as early as 1900. A new, first-of-its-kind study by scientists at Columbia University’s Earth Institute, published Wednesday in the journal Nature, largely confirms what climate models have shown. In the absence of strong historic data on precipitation, those computer models forecast not only future scenarios, but shed light on historical trends.

An early look at the 2020 electorate The 2020 U.S. presidential election is rapidly coming into view – and so is the electorate that will determine its outcome. While demographic changes unfold slowly, it’s already clear that the 2020 electorate will be unique in several ways. Nonwhites will account for a third of eligible voters – their largest share ever – driven by long-term increases among certain groups, especially Hispanics. The Simplest Explanation Of Global Warming Ever Earth energy budget diagram, with incoming and outgoing radiation (values are shown in W/m^2). Satellite instruments (CERES) measure the reflected solar, and emitted infrared radiation fluxes. The energy balance determines Earth's climate. Let's play pretend for a moment. Pretend, if you can, that you've never heard about the idea of global warming before. Pretend you've never heard anyone else's opinions on the matter, including from politicians, scientists, friends or relatives.

Medicaid work requirements: Where do they stand after the blue wave? The 2018 midterm elections have dealt a significant setback to President Trump’s agenda in the legislative arena. However, there are still many ways for the Trump administration to keep swinging away at the Affordable Care Act. One particularly effective unilateral instrument is the regulatory process – that is, the implementation of statutory law by executive agencies. This may prove particularly consequential for Medicaid, the health coverage program for those with low incomes or disabilities. One particular area of attention for scholars like me is so-called community engagement or work requirements for Medicaid beneficiaries.

40 million Americans depend on the Colorado River. It’s drying up. Prompted by years of drought and mismanagement, a series of urgent multi-state meetings are currently underway in Las Vegas to renegotiate the use of the Colorado River. Seven states and the federal government are close to a deal, with a powerful group of farmers in Arizona being the lone holdouts. The stakes are almost impossibly high: The Colorado River provides water to 1-in-8 Americans, and irrigates 15 percent of the country’s agricultural products. The nearly 40 million people who depend on it live in cities from Los Angeles to Denver. The river supports native nations and industry across the vast desert Southwest — including 90 percent of U.S. Circumcision: Social, Sexual, Psychological Realities We continue examining myths about circumcision, including traditions, social and sexual relations.

How Russia is growing its strategic influence in Africa Much has been made about China’s role and profile in Africa and the factors underlying its activities on the continent. Less debated is the spread and depth of Russia’s contemporary presence and profile in Africa. There was a strong Russian influence in Africa during the heyday of the Soviet Union. The post-independence governments of Angola, Mozambique, Guinea-Bissau, Democratic Republic of Congo, Egypt, Somalia, Ethiopia, Uganda and Benin at some point all received diplomatic or military support from the Soviet Union. But this began to change after the superpower started to collapse in December 1991.

The Tiny Swiss Company That Thinks It Can Help Stop Climate Change Later, Wurzbacher told me he wants to offer a “one click” consumer service, perhaps in a year or two, which would expand what they’re doing in Iceland to individual customers and businesses. A Climeworks app could be installed on my smartphone, he explained. It could then be activated by my handset’s location services. “You fly over here to Europe,” he explained, “and the app tells you that you have just burned 1.7 tons of CO₂. Do you want to remove that?
