Today, global temperatures are increasing by about <a href=\"https:\/\/dev-04-drupal-climate.woc.noaa.gov\/news-features\/understanding-climate\/climate-change-global-temperature\" target=\"_blank\" rel=\"noopener\">0.36 degrees Fahrenheit (0.2 degrees Celsius) per decade<\/a>. <\/p>\n\n<p>Imagine a car speeding up. Over time, human activities such as burning fossil fuels <a href=\"https:\/\/gml.noaa.gov\/ccgg\/trends\/gl_gr.html\" target=\"_blank\" rel=\"noopener\">have increased the amount of greenhouse gases<\/a> in the atmosphere. These gases <a href=\"https:\/\/scied.ucar.edu\/learning-zone\/how-climate-works\/greenhouse-effect\" target=\"_blank\" rel=\"noopener\">trap heat from the Sun<\/a>. This is like pressing the gas pedal. The faster the driver adds gas, the faster the car goes.<\/p>\n\n<p>The 21st century has seen a dramatic acceleration in the rate of climate change, with global temperatures rising <a href=\"https:\/\/www.climate.gov\/news-features\/understanding-climate\/climate-change-global-temperature\" target=\"_blank\" rel=\"noopener\">more than three times faster<\/a> than in the previous century.<\/p>\n\n<p>The <a href=\"https:\/\/www.ipcc.ch\/report\/ar6\/syr\/downloads\/report\/IPCC_AR6_SYR_SPM.pdf\" target=\"_blank\" rel=\"noopener\">faster pace and higher temperatures<\/a> are changing habitat ranges for plants and animals. In some regions, the pace of change is also throwing off the delicate timing of pollination, putting plants and pollinators such as bees at risk.<\/p>\n\n<h2 id=\"some-species-are-already-migrating\">Some species are already migrating<\/h2>\n\n<p>Most plant and animal species can tolerate or at least recover from short-term changes in climate, such as a heat wave. When the changes last longer, however, organisms may need to migrate into new areas to adapt for survival.<\/p>\n\n<p>Some species are already moving toward higher latitudes and altitudes with cooler temperatures, altering their geographic territory to stay within their optimal climate. <a href=\"https:\/\/doi.org\/10.3354\/meps08220\" target=\"_blank\" rel=\"noopener\">Fish populations<\/a>, for example, have <a href=\"https:\/\/web.archive.org\/web\/20241213122416\/https:\/www.epa.gov\/climate-indicators\/climate-change-indicators-marine-species-distribution\" target=\"_blank\" rel=\"noopener\">shifted toward the poles<\/a> as ocean temperatures have risen.<\/p>\n\n<p><iframe loading=\"lazy\" id=\"VhiAY\" class=\"tc-infographic-datawrapper\" src=\"https:\/\/datawrapper.dwcdn.net\/VhiAY\/1\/\" height=\"400px\" width=\"100%\" style=\"border: 0;\" scrolling=\"no\" frameborder=\"0\"><\/iframe><\/p>\n\n<p>Pollinators such as bees can also shift their ranges.<\/p>\n\n<p>Bumblebees, for example, are adapted for cooler regions because of their fuzzy bodies. Some bumblebee populations have been <a href=\"https:\/\/doi.org\/10.1002\/ece3.10284\" target=\"_blank\" rel=\"noopener\">disappearing from the southern parts<\/a> of their geographic range and have been found in cooler regions to the north and in more mountainous areas. That could increase competition with existing bumblebee populations.<\/p>\n\n<h2 id=\"plants-and-pollinators-can-get-out-of-sync\">Plants and pollinators can get out of sync<\/h2>\n\n<p>Plants and their pollinators face another problem as the rate of climate change increases: Many plants rely on insects and other animals for seed and pollen dispersal.<\/p>\n\n<p>Much of that pollen dispersal is accomplished by native pollinators. About 75% of plant species in North America require an insect pollinator \u2013 bees, <a href=\"https:\/\/theconversation.com\/butterflies-declined-by-22-in-just-2-decades-across-the-us-there-are-ways-you-can-help-save-them-251468\" target=\"_blank\" rel=\"noopener\">butterflies<\/a>, moths, flies, beetles, wasps, birds and bats. In fact, <a href=\"https:\/\/www.usda.gov\/about-usda\/general-information\/initiatives-and-highlighted-programs\/peoples-garden\/importance-pollinators\" target=\"_blank\" rel=\"noopener\">1 in 3 bites of food<\/a> you eat depend on a pollinator, according to the U.S. Department of Agriculture.<\/p>\n\n<p>So, even if a species successfully migrates into a new territory, it can face a mismatch of pollination timing.

These insect pollinators use <a href=\"https:\/\/doi.org\/10.1042\/ETLS20190139\" target=\"_blank\" rel=\"noopener\">temperature and daylight length as cues<\/a> for when to emerge or when to migrate to their spring and summer habitats. <\/p>\n\n<p>As the rate of climate change increases, the <a href=\"https:\/\/doi.org\/10.1042\/ETLS20190139\" target=\"_blank\" rel=\"noopener\">chances of a timing mismatch<\/a> between pollinators and the plants they pollinate rise. <\/p>\n\n<p>With an increase in temperature, many plants are <a href=\"https:\/\/doi.org\/10.1111\/j.1365-2486.2006.01193.x\" target=\"_blank\" rel=\"noopener\">blooming earlier in the spring<\/a>. If bees or other pollinators emerge at their \u201cnormal\u201d time, flowers may already be blooming, reducing their chance for pollination. <\/p>\n\n<p>If pollinators <a href=\"https:\/\/doi.org\/10.1038\/s41559-019-1062-4\" target=\"_blank\" rel=\"noopener\">emerge too early<\/a>, they may struggle to survive if their normal food sources are not yet available. Native bees, for example, <a href=\"https:\/\/extension.illinois.edu\/blogs\/everyday-environment-blog\/2024-09-12-pollinators-complicated-relationship-climate-change\" target=\"_blank\" rel=\"noopener\">rely on pollen for much of the protein<\/a> they need for growing and thriving.<\/p>\n\n<h2 id=\"wild-bees-are-emerging-earlier\">Wild bees are emerging earlier<\/h2>\n\n<p>This kind of shift in timing is already happening with bees in the U.S.<\/p>\n\n<p>Studies have shown that the date wild bees emerge in the U.S. has <a href=\"https:\/\/doi.org\/10.1073\/pnas.1115559108\" target=\"_blank\" rel=\"noopener\">shifted by 10.4 days<\/a> earlier over the past 130 years, and the pace is accelerating. <\/p>\n\n<p>One study found wild bees across species have been changing their phenology, or timing of seasonal activities, and over the past 50 years the emergence date is <a href=\"https:\/\/doi.org\/10.1111\/1365-2656.13778\" target=\"_blank\" rel=\"noopener\">four times faster<\/a>.
