World Scientists’ Warning of a Climate Emergency

BioScience: “Scientists have a moral obligation to clearly warn humanity of any catastrophic threat and to “tell it like it is.” On the basis of this obligation and the graphical indicators presented below, we declare, with more than 11,000 scientist signatories from around the world, clearly and unequivocally that planet Earth is facing a climate emergency. Exactly 40 years ago, scientists from 50 nations met at the First World Climate Conference (in Geneva 1979) and agreed that alarming trends for climate change made it urgently necessary to act. Since then, similar alarms have been made through the 1992 Rio Summit, the 1997 Kyoto Protocol, and the 2015 Paris Agreement, as well as scores of other global assemblies and scientists’ explicit warnings of insufficient progress (Ripple et al. 2017). Yet greenhouse gas (GHG) emissions are still rapidly rising, with increasingly damaging effects on the Earth’s climate. An immense increase of scale in endeavors to conserve our biosphere is needed to avoid untold suffering due to the climate crisis (IPCC 2018).

Most public discussions on climate change are based on global surface temperature only, an inadequate measure to capture the breadth of human activities and the real dangers stemming from a warming planet…. Policymakers and the public now urgently need access to a set of indicators that convey the effects of human activities on GHG emissions and the consequent impacts on climate, our environment, and society. Building on prior work… we present a suite of graphical vital signs of climate change over the last 40 years for human activities that can affect GHG emissions and change the climate.., as well as actual climatic impacts… We use only relevant data sets that are clear, understandable, systematically collected for at least the last 5 years, and updated at least annually…”

Visualizing the Effects of Bad Weather and the Trade War on Farmers

Center for Data Visualization – “The Wall Street Journal has created a series of data visualizations showing how bad weather and the United States-China trade war have created significant challenges for U.S. farmers. The visualizations show that the months between July 2018 and June 2019 were the wettest in the United States since record-keeping began… Continue Reading

600 Years of Grape Harvests Document 20th Century Climate Change

Earth and Space Science News (EOS) – “Climate change isn’t just captured by thermometers—grapes can also do the trick. By mining archival records of grape harvest dates going back to 1354, scientists have reconstructed a 664-year record of temperature traced by fruit ripening. The records, from the Burgundy region of France, represent the longest series… Continue Reading

Climate Change Is Triggering More Heat Waves, Droughts, And Crop Yield Declines

“Land is already under growing human pressure and climate change is adding to these pressures. At the same time, keeping global warming to well below 2ºC can be achieved only by reducing greenhouse gas emissions from all sectors including land and food, the Intergovernmental Panel on Climate Change (IPCC) said in its latest report  –… Continue Reading

You Are What You Watch? The Social Effects of TV

The New York Times – There’s new evidence that viewing habits can affect your thinking, political preferences, even cognitive ability. “Other than sleeping and working, Americans are more likely to watch television than engage in any other activity. A wave of new social science research shows that the quality of shows can influence us in… Continue Reading
