New Research shows how Global Warming is Messing with our Rainfall

The past century of human-induced warming has increased rainfall variability over 75% of the Earth’s land area—particularly over Australia, Europe and eastern North America, new research shows.

The findings, by Chinese researchers and the UK Met Office, were published in the journal Science. They provide the first systematic observational evidence that climate change is making global rainfall patterns more volatile.

Climate models had predicted this variability would worsen under climate change. But these new findings show rainfall variability has already worsened over the past 100 years—especially in Australia.

Past studies of the observational record either focused on long-term average rain, which is not systematically changing globally...

Shear genius: Researchers find way to Scale up Wonder Material, which could do wonders for the Earth

Many industries use carbon capture to reduce emissions of carbon dioxide, which has little commercial value. However, with minimal energy input, using electricity to catalyze a reaction, MOF-525 can convert the captured CO2 to carbon monoxide — a chemical that is valuable in manufacturing.

Researchers at the University of Virginia School of Engineering and Applied Science have figured out how to take a miracle material, one capable of extracting value from captured carbon dioxide, and do what no one else has: make it practical to fabricate for large-scale application.

The breakthrough from chemical engineering assistant professor Gaurav “Gino” Giri’s lab group has implications for the cleanup of the greenhouse gas, a major contributor to the climate change dilemma...

Heat-related Cardiovascular Deaths in the U.S. may more than Double within Decades

In nationwide projections, elderly and Black adults are most at risk for cardiovascular death due to extreme heat, finds a new study. Cardiovascular deaths from extreme heat in the U.S. may more than double by the middle of the century. Without reductions in greenhouse gas emissions, that number could even triple, according to new research published today in the American Heart Association’s flagship journal Circulation.

“Climate change and its many manifestations will play an increasingly important role on the health of communities around the world in the coming decades, ” said lead study author Sameed Khatana, M.D., M.P.H...

Why the day is 24 hours long: Astrophysicists reveal why Earth’s Day was a Constant 19.5 hours for over a Billion Years

Result sheds new light on how climate change will affect the length of the day and validity of climate modelling tools. A team of astrophysicists at the University of Toronto (U of T) has revealed how the slow and steady lengthening of Earth’s day caused by the tidal pull of the moon was halted for over a billion years.

They show that from approximately two billion years ago until 600 million years ago, an atmospheric tide driven by the sun countered the effect of the moon, keeping Earth’s rotational rate steady and the length of day at a constant 19.5 hours.

Without this billion-year pause in th...
