Climate change threatens breeding birds: Birds risk starvation if they start breeding early due to climate change

climate change threatens breeding birds: birds risk starvation if they start breeding early due to climate change

BEGIN ARTICLE PREVIEW:

The researchers, who examined decades of data on weather, food availability and breeding in Tree Swallows, say that the timing of when to breed and when food is available is becoming decoupled for some animals — highlighting the complexity behind how organisms respond to climate change. “Simply moving dates earlier to track climate change isn’t necessarily risk free. Riskier conditions earlier in the year can expose animals to unintended consequences when responding to bouts of unusually warm spring weather,” says Ryan Shipley, postdoctoral fellow at the Max Planck Institute of Animal Behavior and first author on the paper.
In recent years, studies have raised concerns about whether or not species can adapt, or “keep pace” with climate change. Particular emphasis has been placed on phenology — the timing of life cycle events such as breeding and migration — and the importance of adjusting this to track rising temperatures and earlier arrivals of spring. But the authors say that breeding earlier may place animals at greater risk of exposure to inclement weather events that tend to occur more frequently earlier in the year. They found that Tree Swallows had been advancing breeding by three days every decade for the last 30 years, …

He’s also using his platform on social media to encourage people to talk about their own food stories and think through food and waste — he’s planning to continue hosting Instagram lives to talk about recipes, and topics like kitchen composting.As a self-described queer desi, Sanathra talks about tasty food and the importance of supporting regenerative farming with equal enthusasm. He sees his work as an act against colonialism. “Having everything at your fingertips is a very colonial thought-process,” Sanathra said, “is there a way to encourage people to purchase locally, support local economies? And also support international regenerative farming?” he asks.
Each package comes with a jar of spices as well as recipes to try.
At the moment, he’s working with an organization that works with farmers in Southern India on the border of Kerala and Tamil Nadu. In addition to the recipes, Sanathra intends on bringing stories of the local farmers as well. The region of southern India he is currently sourcing some of the spices from has been impacted by climate change and sees less rainwater. “Cardamon is intensive on resources — a lot of cardamom farmers are using groundwater,” he said as we went on …

As the world’s climate changes, plants and animals have adapted by expanding into new territory and even shifting their breeding seasons. Now, research suggests that over the past 75 years, flowers have also adapted to rising temperatures and declining ozone by altering ultraviolet (UV) pigments in their petals.

Flowers’ UV pigments are invisible to the human eye, but they attract pollinators and serve as a kind of sunscreen for plants, says Matthew Koski, a plant ecologist at Clemson University. Just as UV radiation can be harmful to humans, it can also damage a flower’s pollen. The more UV-absorbing pigment the petals contain, the less harmful radiation reaches sensitive cells.

Previously, Koski and colleagues found that flowers exposed to more UV radiation—usually those growing at higher elevations or closer to the equator—had more UV pigment in their petals. He then wondered whether two factors affected by human activity, damage to the ozone layer and temperature changes, also influenced the UV pigments.

To find out, Koski and colleagues examined plant collections from North America, Europe, and Australia dating back …

DURHAM — Climate change is one of the biggest threats to the plant today, but many people struggle with how they can personally make a difference.
Not anymore.
An international group of GenZ environmentalists — led by Duke undergrad Saad Ibrahim — has launched “You Change Earth,” an interactive site that aims to guide individuals to action.

Funded by Duke’s Nicholas School of the Environment and tech founder Paul English, it provides users with personalized guide on how they can devote their time or money to most effectively reduce their carbon footprint.
“The goal of the project was to create a simple answer to the ever prevalent [question]: ‘What can I do about climate change’,” explained Ibrahim.
“There are millions of people out there who care deeply about the climate crisis, but there is no clear path for them to take action. We wanted to put in their hands an exact guide on how they can bring about meaningful change in their lives and communities.”

How it works: After answering a few short questions on the site, visitors are directed towards a step-by-step guide that shows them how they can start making a difference.

Joe Biden’s plans to make climate change a major focus across his administration if he wins the White House would have significant ramifications for both businesses and consumers. The Democratic nominee seeks not just mass use of electric cars, as California’s governor mandated last week, but further changes across the economy, government and society: Electrified public and freight transportation, power plants running without greenhouse-gas emissions, and the placement of climate concerns at the center of social policies and…

How climate change affects pandemics

how climate change affects pandemics

BEGIN ARTICLE PREVIEW:




Numerous scientists have studied how the 1918 flu spread to become the deadliest pandemic in history and which interventions worked, research that is becoming increasingly relevant during the current coronavirus crisis.But little research has been done on how environmental conditions affected the 1918 pandemic — until now.The 1918 flu coincided with the final years of the World War I, and it’s been well documented that heavy rain and cold temperatures impacted many battles. Now, a new study reveals that the cold, rainy weather was part of a once-in-a-century climate anomaly that occurred from 1914 to 1919 and added to the severity of the 1918 pandemic.

“We knew before, of course, from photos and eyewitness testimonies that the battlefields of Europe were really muddy and rainy and soldiers died of all sorts of exposure, even drowning in the mud and the trenches sometimes. What is news is that in fact it was a six-year anomaly and not just one or two instances,” said lead researcher Alexander More, a research associate at Harvard University’s history department and an associate professor at the University of Maine’s Climate Change Institute.A team of more than a dozen scientists collected and analyzed an Alpine ice core to reconstruct the …

Sounding alarm about climate change, some world leaders, at this week’s annual United Nations meeting warned, “If COVID-19 doesn’t kill us, climate change will.”The warning comes amid Siberia reporting its warmest temperature on record this year and the drastic melting of ice caps in Greenland and Canada.”We are already seeing a version of environmental Armageddon,” Fiji’s Prime Minister Frank Bainimarama was quoted as saying by Associated Press.Bainimarama cited the wildfires in the Western US and also pointed out that the ice chunk sliding into the sea in Greenland was larger than a number of island nations. He said that while this was supposed to be the year “we took back our planet,” the pandemic has diverted the resources and attention from what could have been the marquee issue at the current UN gathering.The Alliance of the Small Island States and the Least Developed Countries Group said, “In another 75 years, many … members may no longer hold seats at the United Nations if the world continues on its present course.”Meanwhile, the UN global climate summit has been postponed to late 2021.As per the 2015 Paris climate accord’s main goal, the rise in global temperatures should be limited to 2 …

BEGIN ARTICLE PREVIEW:

MINNEAPOLIS (AP) — A new University of Minnesota professor in the College of Food, Agriculture and Natural Resource Sciences is creating a University Extension program that will bridge climate research and community outreach.

Heidi Roop — a recent hire in the Department of Soil, Water and Climate— plans to build a hub that will foster conversations about climate change and help farmers and policymakers implement changes based on their research.

“Whether we are aware of it or not, climate is part of our lived experience,” Roop said. “It will touch every one of our lives, and everyone will experience climate change differently. And (one of) the fundamental questions now (is), how do we prepare our communities for the changes?”

Part of Roop’s role will be engaging with important stakeholders, including economists, community leaders, policy makers and farmers, about the impact of the changing climate. Roop will also be conducting her own research on the effectiveness of climate change communication. She will be working with a number of national organizations like the National Aeronautics and Space Administration and the National Oceanic and Atmospheric Administration to analyze weather and climate patterns, The Minnesota Daily reported.

Joel Larson is an associate director of the …

Truth check: Hickenlooper ad targets climate change

truth check: hickenlooper ad targets climate change

BEGIN ARTICLE PREVIEW:

DENVER (KDVR) — The Truth Check team continues to look at the candidates and their commercials in the 2020 election. Every advertisement that claims something — we will research and determine if the ads are actually telling the truth.

You can watch our previous “Truth Check” segments here and you can read our criteria and standards here.

The latest Truth Check involves the highly competitive race for one of Colorado’s United States Senate seats. Former Gov. John Hickenlooper is challenging incumbent Sen. Cory Gardner, who’s defending the seat for the first time.

Hickenlooper’s new ad focuses on climate change.

CLAIM #1 

Solar and wind power fight climate change

Exact quote in ad: “Solar power, wind power… This is how we fight climate change. ”

Verdict: True

Reason: Solar and wind power are two ways to fight climate change. The federal government’s own scientists from NASA and the Environmental Protection Agency agree. They say an increase in greenhouse gases is one of the causes of warmer temperatures and some of those gases come from coal, oil and gas. Replacing those energy sources with solar and wind power cuts down on the greenhouse gases and fights climate change.

CLAIM #2

When Hickenlooper was governor, …
