The climate action plan update before the Manteca Planning Commission essentially provides game plans that the city likely will need to implement to reduce locally generated greenhouse gas emissions.

It is based on scenarios of what will happen if such emissions aren’t reduced.

As such the plan — prepared with the help of Raney Planning & Management— expects in Manteca that:

*the current annual average maximum daily temperature of 74.4 degrees based on the last 30 years will increase 3.8 degrees to 78.2 degrees by mid-century which is a 2035 to 2064 time frame.

*extreme heat days will go from four to 11 annually.

*the minimum annual temperature will go from 48.1 degrees to 51.3 degrees in the same time frame for an increase of 3.3 degrees.

*dry years will become drier while wet years will become wetter.

*annual precipitation of 12.1 inches based on the last 30 years will drop 0.2 inches to 11.9 inches.

*increased wildfires surrounding the San Joaquin Valley will create significant problems,

Although not local in origin, wildfire smoke and soot is expected to see increased Manteca public health impacts such as asthma and other respiratory ailments due to exposure to air pollution.

It likely will also mean an increase in the cancellation of sporting events and school physical education classes.

The city would also need to prepare for increased demand for medical services and fire protection services. The later would be due to drier weather during dry years exacerbating brush fire conditions as well as heat-related illnesses.

The temperature and precipitation changes, both locally and on the Stanislaus River watershed that the city partially relies on, will create pressure to further conserve water use in Manteca  beyond current efforts.

The commission meets at 6 p.m. tonight in the Manteca City Council chambers.
