With climate change, spring is getting warmer and coming an average of 3 days earlier across the U.S. than a few decades ago. Our 2015 analysis shows how many days earlier spring is arriving in your state.
A new study indicates that if current emission rates of greenhouse gases continue, leaves will begin to appear an average of 21 days earlier nationally by 2100 compared to recent trends. Because plants and animals take their habitual cues from the seasonal rise in temperatures and the increasing amount of daylight that come in the spring, warming can distort their well-established behavioral patterns. These disruptions can have a cascading effect on the environment and economy.
Warming springs can cause plants to bloom earlier, change the locations of migrating species, alter the awakening time of hibernating animals, and increase the seasonal insect populations. As a result, plants may bloom before their needed pollinators are available, and aggressive insects can cause damage to food crops. These effects have the potential to threaten agricultural yields, driving up food prices or even causing shortages.
The earlier warming can also make the allergy season worse. Pollen counts have already increased over the last century and are projected to nearly double by 2060. Plus, warmer spring temperatures may increase the growth of certain types of mold, further worsening the season for allergy sufferers.
The current period is a comparison of average first leaf for 1991-2010 to 1961-1980 using data compiled by Mark D. Schwartz (University of Wisconsin-Milwaukee) and the U.S. National Phenology Network. Projected values, based on CMIP5 model, RCP 8.5 scenario, are as calculated by the author of ”Spring plant phenology and false springs in the conterminous U.S. during the 21st century.” The baseline of the new study is a modeled 1950-2005 average first date of leaf out.

Having productive conversations about climate change isn't only challenging when dealing with skeptics, it can also be difficult for environmentalists, according to two new studies.
Injecting carbon dioxide (CO2) deep below the seabed could be an important strategy for mitigating climate change, according to some experts. However, scientists need a reliable way to monitor such sites for leakage of the greenhouse gas. Now, researchers have studied natural sources of CO2 release off the coast of ...

Every several hundred thousand years or so, Earth's magnetic field dramatically shifts and reverses its polarity. Geologist found that the most recent field reversal, some 770,000 years ago, took at least 22,000 years to complete. That's several times longer than previously thought, and the results further call into question controversial ...

New Jersey's Attorney General recently continued his opposition to the proposed PennEast pipeline by asking a federal judge to reconsider whether the private company can seize state-owned lands.
Air pollution -- especially ozone air pollution which is increasing with climate change -- accelerates the progression of emphysema of the lung, according to a new study.
Corals have been dominant framework builders of reef structures for millions of years. Ocean acidification, which is intensifying as climate change progresses, is increasingly affecting coral growth. Scientists have now answered some questions regarding whether and how corals can adapt to these changes by having gained important insights into the ...
Operational models for severe weather forecasting predicted Hurricane Harvey would become a Category 1 hurricane in 2017. Instead, it became a massive Category 4 just before it made landfall, tying Hurricane Katrina for the costliest hurricane on record.

A bipartisan group of elected officials today joined conservation leaders and citizen landowners whose land will be seized by PennEast pipeline after a court ruling on Friday, in opposition to an infrastructure project that will serve no public benefit.
Researchers have mapped out how much waves are likely to change around the globe under climate change and found that if we can limit warming to 2 degrees, signals of wave climate change are likely to stay within the range of natural climate variability.

A rare bright spot among dismal climate change predictions, new research findings show that some singing insects are likely to manage to reproduce even in the midst of potentially disruptive temperature changes.
Over the recent decade, total human impacts to the world's oceans have, on average, nearly doubled and could double again in the next decade without adequate action.
Molecular interactions between gases and liquids underpin much of our lives, but difficulties in measuring gas-liquid collisions have so far prevented the fundamental exploration of these processes. Researchers hope their new technique of enabling the visualization of gas molecules bouncing off a liquid surface will help climate scientists improve their ...
Forests in the eastern United States that are structurally complex -- meaning the arrangement of vegetation is highly varied -- sequester more carbon, according to a new study. The study demonstrates for the first time that a forest's structural complexity is a better predictor of carbon sequestration potential than tree ...
