Furthermore, a study from Current Biology found that the UV pigmentation of various flowers has changed in response to the climate crisis and the ozone crisis. Certain flowers have UV pigments that are invisible to the human eye but attract pollinators. The aforementioned environmental stressors can cause these flowers to produce more pigment — making it more difficult for pollinators to find the buds, potentially harming the flowers’ ability to propagate.
Matthias Forkel, a co-author of the study, echoed this sentiment in a report from National Geographic: “Plants and ecosystem take up around 25 percent of the human-caused fossil fuel emissions. Another 25 percent is taken up by the ocean, and the remaining 50 percent of CO2 emissions stay in the atmosphere. If plants grow more, they take up more carbon but the effect is small, far too small to compensate for the human CO2 emissions.”
Go Deeper: The hope is that we can significantly limit our global output of carbon dioxide, but if we stay on our current high-emissions trajectory, scientists have some ideas for how an increase of CO2 in the atmosphere could make plants and humans thirstier.
After a four-year hiatus under the Trump administration, the Environmental Protection Agency’s Climate Change Indicators website is back in action. The public portal includes data on 54 indicators including sea-level rise, Great Lakes ice cover, heat waves, river flooding, and residential energy use.
Why This Matters: People are experiencing the impacts of climate change in their everyday lives, from hotter temperatures to more intense wildfire seasons.
When reading about climate change, you’ll often come across the unit of measurement called a “metric ton of CO2.” That sounds like a lot, but the unit is a bit abstract for most of us when our reference point for a ton is a VW Beetle, the Liberty Bell, or even a baby humpback whale […]
According to a new report from Christian Aid, Kenya, which produces half of all black tea consumed by the UK, may lose a quarter of its growing capacity by 2050, and the tea that makes it into drinkers’ cups may taste a lot different than before. The decline of tea farming has implications for economies worldwide, including Kenya, India, China, and Sri Lanka.
Why This Matters: Tea is the most popular drink other than water globally and the tea industry employs more than 3 million people in Africa alone.
