Grass Heads

Grasslands give way to deserts on a warming planet.

Canadian Yew Stomata

Stomata are a pair of cells on leaves, seeds, flowers; they are crucial for plant survival and thus, for all life on earth.

Camas Lily Pollen

Climate change is leading to higher pollen levels, resulting in increased asthma and allergies.

Cedar Stomata

Stomata draw in CO2, and "exhale" water and oxygen.

Ginkgo Stomata

The ginkgo is one of the oldest living tree species on Earth. For over 200 million years, the ginkgo has adapted to numerous cycles of climate warming and cooling. Could this rune-like stomata have something to do with its long success?

Red Algae and Diatoms

As ocean temperatures rise, some diatom populations are declining. Diatoms produce half of the globe's oxygen. These diatoms are one hundredth of a pinhead wide.

Hummingbird Feather Detail

With warming temperatures, flowers bloom earlier in the spring. Will hummingbirds migrate in time to help pollinate these flowers and obtain food for their young?

Holly Stomata

As temperatures rise with climate change, some stomata close, robbing plants of carbon, which leads to accelerated tree death, especially in the tropics.

Poplar Stomata

There are proposals to plant extensive poplar plantations to store carbon, or process the trees into ethanol for fuel, but this is controversial.

Wasp Nest Fibers

Researchers in Britain have found that wasps favor warmer temperatures, and their numbers are increasing.

Stinging Nettle Stomata

Nettles are high in nutrients and minerals. With climate change, nettles and crucial food crops have fewer nutrients but more carbs.

Camas Lily Stomata

The whole sequence of wildflower blooms is becoming less predictable, disrupting ancient pollinator/plant relationships.

Filaree Seeds

Rain prompts these seeds to spin and drill themselves into the ground.

Arbutus Seeds

More frequent summer droughts in the Pacific Northwest, USA, create dangerous stress for Arbutus trees.Arbutus Seeds

Garry Oak Stomata

Garry oak is a drought-tolerant tree in the Pacific Northwest, USA. This may give it an advantage as other trees suffer.

Wildflower Anther

Increased drought shrivels crops and seeds.

Mosquito, Fruit Fly, Wasp
Rising temperatures mean expanding ranges for insects, bringing diseases to new, unprepared regions. At the same time, worldwide, insect populations are dramatically declining. In other words, there is chaos.
