Collecting CO2 measurements at the Mauna Loa Observatory in Hawaii.

Studying ancient ring cores to compare to climatic events.

The use of concrete, glass, and steel have different thermal bulk properties than natural elements and change the energy balance due to the holding of heat.

The urban environment causes human health issues such as asthma.

Energy consumption is down due to most of the population living in condensed urban environments now and not in rural areas.

Temperatures in the urban core are lower at night due to the lack of solar radiation reaching the man-made surfaces.

It is affected by the surrounding ecological context, the size of the city, and the shape of the city.

True

False

Grasslands produce small but frequent fires.

Frequency and severity of fires are determined by the availability of fuel.

Closed forests produce large but infrequent fires.
