UrduFlorida is projected to lose 3.5 million acres of land to development by 2070. A new study highlights how Florida can buffer itself against both climate change and population pressures by conserving the remaining 8 million acres of “opportunity areas” within the Florida Wildlife Corridor (FLWC), the only designated statewide corridor in the U.S.

Drought, Soil Desiccation Cracking, and Carbon Dioxide Emissions: An Overlooked Feedback Loop Exacerbating Climate Change
Soil stores 80 percent of carbon on earth, yet with increasing cycles of drought, that crucial reservoir is cracking and breaking down, releasing even more greenhouse gases creating an amplified feedback loop that could accelerate climate change.
Heat-related cardiovascular deaths in the U.S. may more than double within decades

Illinois-led team puts cows and microbes to work to reduce greenhouse gases
With funding from the Foundation for Food and Agriculture Research, University of Illinois faculty, along with an international team of scientists, is recruiting a surprising ally to make a powerful dent in greenhouse gas emissions: the cow. The team will work to re-route hydrogen atoms away from methane during the fermentation process in the rumen, toward more productive end products.

Important ocean currents that redistribute heat, cold and precipitation between the tropics and the northernmost parts of the Atlantic region will shut down around the year 2060 if current greenhouse gas emissions persist.
Curbing waste improves global food security but has limited environmental benefits
Reducing waste is one way to help combat hunger around the world, but stricter control over food loss and waste does not lead to better environmental outcomes, according to researchers at the University of California, Irvine and the University of Colorado Boulder. In a paper published recently in Nature Food, the scientists stress that curbing food spoilage increases the amount of produce in markets, which leads to lower costs.
‘Red sea plume’ alga may cut greenhouse gas emissions from cow poo nearly in half
Approximately a third of all anthropogenic methane is emitted by ruminant livestock. These animals get nutrients through fermenting food in four-chambered stomachs found in cows, sheep, and goats.

Researchers at the University of New Hampshire studied a practice known as silvopasture which intentionally preserves trees in pastures where livestock graze. They found that compared to a completely cleared, tree-less, open pasture, the integrated silvopasture released lower levels of carbon dioxide and nitrous oxide and soil carbon storage remained the same, offering a possible alternative for farmers with less climate consequences.

Catastrophic Sea-Level Rise from Antarctic Melting is Possible with Severe Global Warming
The Antarctic ice sheet is much less likely to become unstable and cause dramatic sea-level rise in upcoming centuries if the world follows policies that keep global warming below a key 2015 Paris climate agreement target, according to a Rutgers coauthored study. But if global warming exceeds the target – 2 degrees Celsius (3.6 degrees Fahrenheit) – the risk of ice shelves around the ice sheet’s perimeter melting would increase significantly, and their collapse would trigger rapid Antarctic melting. That would result in at least 0.07 inches of global average sea-level rise a year in 2060 and beyond, according to the study in the journal Nature.

How did rocks rust on Earth and turn red? A Rutgers-led study has shed new light on the important phenomenon and will help address questions about the Late Triassic climate more than 200 million years ago, when greenhouse gas levels were high enough to be a model for what our planet may be like in the future.
Important Climate Change Mystery Solved by Scientists
Scientists have resolved a key climate change mystery, showing that the annual global temperature today is the warmest of the past 10,000 years – contrary to recent research, according to a Rutgers-led study in the journal Nature. The long-standing mystery is called the “Holocene temperature conundrum,” with some skeptics contending that climate model predictions of future warming must be wrong. The scientists say their findings will challenge long-held views on the temperature history in the Holocene era, which began about 12,000 years ago.

Since 2014, the University of Utah has maintained research-grade suites of air quality instruments installed on light rail trains. These mobile sensors cover the same area as 30 stationary sensors, providing the Salt Lake Valley with a highly cost-effective way to monitor its greenhouse emissions and fill in gaps in emissions estimates.
Best Region For Life on Mars Was Far Below Surface
The most habitable region for life on Mars would have been up to several miles below its surface, likely due to subsurface melting of thick ice sheets fueled by geothermal heat, a Rutgers-led study concludes. The study, published in the journal Science Advances, may help resolve what’s known as the faint young sun paradox – a lingering key question in Mars science.
