Dear editor,

Ed McDonald dismisses the threat posed by human-caused global warming. (Letters underscore the misconceptions, falsehoods and hysteria behind climate change, March 28 letter to the editor)

I encourage McDonald to read Exxon鈥檚 1982 primer titled 鈥溾�� This internal company document is available online and reveals that Exxon accepted the scientific foundation for human-caused climate change over 35 years ago, along with many of the associated risks, such as sea level rise and decreased agricultural production.

Moreover, in a 1978 presentation to Exxon management, company science adviser J.F. Black warned that an increase in global temperature of two degrees Celsius would be likely to affect the distribution of the world鈥檚 rainfall. According to Black: 鈥淪ome countries would benefit, but others could have their agricultural output reduced or destroyed.鈥�

These are the types of climate impacts that world hunger organizations like Bread for the World () and Christian Aid () are observing today.

Consistent with these concerns, the (https://bit.ly/2FVQaNc) states that climate hazards like heat waves, droughts and floods 鈥渁re increasing water and food insecurity around the world,鈥� heightening the risk of social unrest and migration in places like the Middle East.

Our common values like national security and caring for 鈥渢he least of these鈥� should unify us on this issue. It just doesn鈥檛 make sense to make the long-term changes to the Earth鈥檚 physics and chemistry we are making without looking at this closely together, across political divides, with open ears and open hearts.

Let鈥檚 urge our politicians and business leaders to work together and find a path to slow climate change.

Terry Hansen,

Hales Corners, Wisconsin
