According to the World Bank, the number of people in poverty will climb from 68 million to 132 million by 2030 because of climate change. The existence of global poverty is common knowledge, but many of us remain unaware of the leading cause. Climate change is the culprit of the devastating droughts and natural disasters that have created lasting effects on poverty levels worldwide. The consequences of climate change include food shortages, water shortages, loss of shelter, and a loss of livelihood, each of which are defining factors of poverty.
A joint U.S.-European satellite, built to monitor global sea levels, lifted off on a SpaceX Falcon 9 rocket from Vandenberg Air Force Base just after 9 a.m. Pacific Time on November 21, 2020. About the size of a small pickup truck, Sentinel-6 Michael Freilich will extend a nearly 30-year continuous dataset on sea surface height.
As recently reported in the Financial Times, if every British person sent one fewer thank you email a day, it would save 16,433 tonnes of carbon a year, equivalent to tens of thousands of flights to Europe.
In his book After Sustainability, author John Foster approaches the issue of climate change as a philosopher, and he’s convinced that denial is not just something that the bad guys do. We’re all involved in a complex culture of denial, he suggests, and climate activists are as likely to be caught up in it as everyone else.
As seas rise and coastal storms intensify, policymakers and low-lying cities around the globe are increasingly wrestling with the reality of needing to relocate entire communities to higher, safer ground. Scientists estimate that up to 340 million people in coastal areas could be displaced by 2050, and 630 million by 2100, in locations from the United States to Nigeria to the Philippines.
The Sentinel-6 will see details that previous sea level missions couldn’t. Existing satellites can track large phenomena stretching thousands of miles, such as the Gulf Stream and weather patterns like El Niño and La Niña. But smaller sea-level fluctuations near coastlines exceed their abilities. Sentinel-6’s higher resolution measurements will enable researchers to see finer, more complicated ocean features, especially near shorelines. It will also offer faster data turnarounds—collecting, processing, and releasing data within three hours, down from months and years. The data can be used to more quickly and accurately predict, map, and 3D model coastline changes; weather, such as hurricane intensity; ocean current fluctuations, which dissipate climate energy; and ocean topography and circulation, as movement of heat, salt, pollution, and nutrients impacts marine ecosystems.
