How should we teach children about climate change?

  How should we teach children about climate change? Experts say it's time for India's schools to start teaching climate change as a distinct subject.Hardly anyone picks environment, he said. Not even in recent years since the perils of climate change have become more real everywhere - temperatures are higher than ever, glaciers are melting faster, violent cyclones and wildfires have become common, and children are at higher risk because of all of this.

When USA TODAY began reporting on how climate change affects precipitation, it found a stunning shift in the way rain falls across much of America.

East of the Rockies, more rain is falling and it’s coming in more intense bursts. In the West, people are waiting longer to see any rain at all. Some areas are seeing more dramatic swings between both extremes –whipsawing from rainfall and drought to rainfall again.

Although impact of this shift is felt nationwide, some states are getting an extra wallop, USA TODAY found. These states include Michigan, Pennsylvania, Ohio, Arkansas and Iowa.

To help explain the impact of those precipitation changes, USA TODAY turned to Full Sail University in Winter Park, Florida. Faculty members at the music and recording school agreed to compose original music for each state based on more than a century of precipitation data.

Each composer used different musicalities to bring their pieces to life, but all used real rain sounds in their work.

Listen to the pieces, see the data and learn more about the artists and how they chose their approach below:

Pennsylvania, by Timothy Stulman

Timothy Stulman, a composer and department chair of music composition, used a melodic line to represent peak rainfall and peak dry years for the state of Pennsylvania.

Get to Know Jon Batiste, the 2022 Grammys' Most-Nominated Artist

  Get to Know Jon Batiste, the 2022 Grammys' Most-Nominated Artist His music stems from a wide range of influences, from his legendary New Orleans family to Sonic the Hedgehog video games The 35-year-old Oscar and Golden Globe winner, bandleader, and multi-genre musician has a great chance of adding another impressive title to his lengthy list of accomplishments: Grammy winner. Batiste is the most Grammy-nominated artist for the 2022 ceremony. The Recording Academy announced on Tuesday that Batiste leads the pack with a whopping 11 nominations, surpassing well-known chart-toppers such as Justin Bieber, Olivia Rodrigo, Doja Cat, and Billie Eilish.

Stulman scaled the highest and lowest rainfall amounts to musical parameters in his software.

Using sounds from the flute and the cello, he matched the highest rainfall year to the highest, loudest flute lines he could get and the lowest rainfall amount is represented by the loudest, lowest cello line.

He gathered recorded sounds of wind, thunder and rain, then combined those with flute and cello melodies.

Higher peak years are represented by higher, louder flute lines, while the driest years are represented by three cellos playing descending melodies. The density and volume directly correlate to the annual rainfall data for Pennsylvania from 1895 forward.

"I wanted to create my own virtual storm so that I would have more granular control over its intensity. So rather than using a single recording of a storm, I used individual sounds of rain, wind, and thunder,” he said. “If there was a really high rainfall year, I would choose recordings of intense rainfall, strong winds, and mix them with loud thunderclaps. So it's not a single recording of a storm, but rather various storm elements blended together based on the rainfall data.”

Climate change: Politicians are failing to deliver justice. Lawyers and scientists could do it in court

  Climate change: Politicians are failing to deliver justice. Lawyers and scientists could do it in court Three climate activists in the UK are challenging the High Court to hear their case, in which they hope to sue their government for its role in the crisis. It's one in a booming number of litigation cases that are leaning on science to bring about justice.It was simple but strong message -- while negotiators made agreements to delay action, island nations in the Pacific such as Tuvalu are sinking in rising seas, and could be swallowed entirely as soon as the end of this century.

Each year is represented by two seconds of music and sound.

Tennessee, by Thomas Owen

Thomas Owen visited Tennessee with his family over the Christmas holidays last winter and had fresh memories of snow blanketing the ground. That piqued his interest in the state’s precipitation, and he found the annual data had “an interesting shape to it.”

“You see these huge spikes of heavy rainfall, said Owen, department chair for recording ar Department Chair for Recording Arts and associate course director of interactive audio. “Sonifying that it’s really easy to hear and be able to tell the difference in climate.”

For this project, rather than a music composition with theoretical elements, he decided to try to create a soundscape of the weather within Tennessee, with actual sounds of rain and wind.  He used a series of actual recordings of rain and wind from the Smoky Mountains in Tennessee.

Through much of the 1900s, the data was fairly similar from year to year, so a listener will hear consistency in the first half of the piece, he said. In the second half, especially during the last 30 years, “you’re going to hear the volatility of having an extreme amount of rain.”

Experts, activists say health equity needs more emphasis in fight against climate change

  Experts, activists say health equity needs more emphasis in fight against climate change When it comes to addressing health and climate, experts say equity must be central.The 26th meeting of the United Nations Framework Convention on Climate Change, or COP26, featured a pavilion that held dozens of events discussing the health threats of climate change. More than 400 health organizations from more than 100 countries signed a letter urging stronger climate change action to protect human health.

Five of Tennessee’s 10 wettest years out of 105 years of data have come in the last 10 years.

Arkansas, Iowa, Michigan, Ohio and Pennsylvania, by Marc Pinsky

From the moment Marc Pinsky heard the proposal to create musical pieces from the data that reveal the precipitation shifts, he was excited.

“My thought was this is the exact project that I’ve been waiting for. It hits upon so many of my passions,” said Pinsky, a course director in audio production. His goal was to make the pieces aesthetically pleasing to someone listening to it as music.

Pinsky was too enthused to choose just one state, so he wrote pieces for five: Arkansas, Iowa, Michigan, Ohio and Pennsylvania. In the pieces looking at the top 10 driest and wettest years, a steady tick occurs for every year, the top 10 driest are represented by low pitched plucked strings, while the top 10 wettest are represented by high pitched plucked strings.

He also prepared a track for the state of Michigan, giving listeners an opportunity to identify wetness and dryness. He ranked each decade on a scale between 1 and 13, and used those numbers to represent notes in the C minor scale, played by a violin.

This served as “sheet music,” resulting in a melody which allows the listener to hear how rainfall amounts increase and decrease over time, he said. As the rainfall increases, the pitch of the violin increases, and as the rainfall decreases, the pitch decreases. He also layered a recording of rain in the background, which also increases and decreases over time.

Billions and trillions: Climate efforts set for big boost if Build Back Better bill passes

  Billions and trillions: Climate efforts set for big boost if Build Back Better bill passes For climate experts and policymakers, $1 trillion is just a start. © Provided by NBC News As the U.S. seeks to prove it’s serious about its international climate commitments, the focus now is on whether the Biden administration can pass its $2 trillion spending bill, which includes $555 billion to fight climate change and could be the new cornerstone of federal climate policy. The $1 trillion bipartisan infrastructure bill passed by Congress this month already commits historic levels of funding for climate projects. But experts say the U.S.

He chose a violin melody for pieces conveying annual precipitation per decade, because that sound, with the higher notes of a violin, reminded him of the sound of a raindrop.

A single note on a violin can be “such a haunting sound and when it's played in the fashion that it was played here,” he said. “It just really, in my opinion, penetrates the soul and that melody line just didn't sound right on any other instrument.”

For the yearly rainfall pieces, he rounded the data to a whole number, then assigned it to a note in the C minor scale, creating a melody that rises and falls in pitch with the changing rainfall amounts.

To more clearly identify the driest years, the note values trigger the sounds of low-pitched instruments including double bass, bassoon, contrabassoon, and synthesized guitar.  The wettest years are represented by high pitched instruments such as piccolo, flute, oboe, and clarinet as well as the bell-like sound of a glockenspiel.

The musical representation speaks to someone in a way that words couldn’t, he said. “I hope it just kind of hits them from an emotional standpoint.”
