how is climate change affecting the health of bees?

Both bees and plants hone in on specific weather cues, like snow melt or air temperature, to let them know when spring has sprung. If weather patterns and temperatures shift beyond the norm, plants and bees may become out of sync, resulting in bees emerging long after the plants are ready to be pollinated.

In recent years, bee populations have been declining globally. Increased rates of colony collapse disorder, climate change, and other factors have contributed to these changes. ... In 2016, seven species of Hawaiian yellow-faced bees were placed on the endangered species list.

Higher temperatures, an increased frequency of storms, sea level rise, and other effects of climate change are likely to affect fish physiology and ecology as well as the operation of aquaculture. Some fish species, such as catfish, may grow more rapidly with higher temperatures but be more vulnerable to disease.

Climate change can potentially affect parapatry by changing species' potential geographic distribution, and thereby widening or shrinking contact zones.

Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns.

Healthy ecosystems and rich biodiversity are fundamental to life on our planet. Climate change is affecting the habitats of several species, which must either adapt or migrate to areas with more favourable conditions. Even small changes in average temperatures can have a significant effect upon ecosystems.

According to the National Climate Assessment, climate change will affect human health by increasing ground-level ozone and/or particulate matter air pollution in some locations. ... The increase in air pollutants makes the effects of increased allergens associated with climate change even worse.

Climate change is a major threat to the health of our planet. Air pollution is closely linked but they are usually treated as separate problems. Rising levels of C02 and other air-polluting gases increase the greenhouse effect, which in turn raises temperatures and affects global weather patterns.

Increased heat, drought, and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns. Explore how climate change is affecting the Southwest.

Research on birds has shown that climate change affects birds both directly and indirectly. The distributions of birds are closely associated with both winter and summer temperatures, and increased temperatures due to climate change may directly affect birds by forcing them to use more energy for thermoregulation.

Honey bees around the globe are in trouble. Due to climate change, pesticides and disease, the Australian Honeybee population is decreasing every year. ... That's more than 20% of honey-producing hives lost in a single decade.

Bees are making a comeback after a period of endangerment caused by a deadly combination of Varroa mites and neonicotinoid pesticides.

The systemic nature of the problem makes it complex, but not impenetrable. Scientists know that bees are dying from a variety of factors—pesticides, drought, habitat destruction, nutrition deficit, air pollution, global warming and more. Many of these causes are interrelated.

Climate change can disrupt food availability, reduce access to food, and affect food quality. For example, projected increases in temperatures, changes in precipitation patterns, changes in extreme weather events, and reductions in water availability may all result in reduced agricultural productivity.

Warmer spring temperatures are causing bees to hatch earlier, putting them out of sync with the flowers that they pollinate, a new study shows.

Climate change will also have many non-thermal impacts on fish populations. For example, changes in the strength, direction and location of ocean currents can affect the probability that fish eggs and larvae survive and grow. Moreover, as temperatures rise, the ability of the ocean to retain oxygen will decrease.
