Avoiding ocean mass extinction from climate warming

By Justin L. Penn and Curtis Deutsch 04/28/22
Climate change brings with it the increasing risk of extinction across species and systems. Marine species face particular risks related to water warming and oxygen depletion. Penn and Deutsch looked at extinction risk for marine species across climate warming and as related to ecophysiological limits (see the Perspective by Pinsky…

Climate change increases cross-species viral transmission risk

By Colin J. Carlson, Gregory F. Albery and Others 04/28/22
At least 10,000 virus species have the capacity to infect humans, but at present, the vast majority are circulating silently in wild mammals. However, climate and land use change will produce novel opportunities for viral sharing among previously geographically-isolated species of wildlife...

What’s the State of YOUR Air

For 23 years, the American Lung Association has analyzed data from official air quality monitors to compile the State of the Air report. The more you learn about the air you breathe, the more you can protect your health and take steps to make the air cleaner and healthier.

What Cities Should Know About Climate Change and Populations on the Move

By Anna Marandi and Kelly Leilani 04/21/22
Americans have historically been some of the most mobile people in the world, continually seeking better housing and job opportunities. However, in recent years, mobility — particularly among young Americans — has slowed, due largely to dramatic increases in housing prices and housing-related debt among American families since the Great…

The Asset Managers Fueling Climate Chaos

By Lara Cuvelier 04/20/22
We surveyed 30 major asset managers, mostly headquartered in Europe (25) and in the US (5) and among the biggest institutions worldwide in terms of assets under management. We analyzed their investment practices regarding climate change, focusing on the fossil fuel sector as the priority sector to tackle. The first…

Methane emissions from US low production oil and natural gas well sites

By Mark Omara, Daniel Zavala-Araiza and Others 04/19/22
Mitigation of methane (CH4) emissions, a powerful greenhouse gas with >80× the 20-year warming potential of carbon dioxide is widely recognized as strategically integral to the attainment of the climate-neutrality goals of Paris Agreement. In the United States, official estimates from the US Environmental Protection Agency (EPA) indicate nearly one-third…

Attribution of 2020 hurricane season extreme rainfall to human-induced climate change

By Kevin A. Reed, Michael F. Wehner and Colin M. Zarzycki 04/12/22
Hurricanes are among the most costly and deadly geophysical extremes on Earth. Hurricane damage is caused by extreme wind speeds and flooding due to storm surge and heavy amounts of rainfall over relatively short periods of times. The recent 2020 North Atlantic hurricane season was a clear example of the…

Global Warming of 1.5 ºC

An IPCC special report on the impacts of global warming of 1.5 °C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty...

Zeroing in on Healthy Air

Zeroing in on Healthy Air finds that a widespread transition to zero-emission cars, trucks, buses and other vehicles, coupled with non-combustion, renewable energy resources would yield tremendous air quality, public health and climate benefits across the United States. To illustrate the potential benefits, a transition to 100 percent sales of…

Global Energy Review: CO2 Emissions in 2021

The global CO2 emissions and energy demand numbers are based on the IEA’s detailed region-by-region and fuel-by-fuel analysis, drawing on the latest official national data and publicly available energy, economic and weather data. Combined with the methane emissions estimates published by the IEA and estimates of nitrous oxide and flaring…

Podcast: Paulina Jaramillo on the IPCC’s new climate-solutions report

By David Roberts Photo: Paulina Jaramillo 04/13/22
Anyone who’s followed climate change for a while has become accustomed to the cycle of reports from the Intergovernmental Panel on Climate Change (IPCC) — the dire warnings, the brief flurry of press coverage, and the rapid return to normal. It’s easy for them to blur together.

Revolutionary changes in transportation could slow global warming

By Alan Jenn Photo: Michael M. Santiago/Getty Images 04/04/22
Around the world, revolutionary changes are under way in transportation. More electric vehicles are on the road, people are taking advantage of sharing mobility services such as Uber and Lyft, and the rise in telework during the COVID-19 pandemic has shifted the way people think about commuting.

Emissions must peak in 3 years to avoid worst climate change impacts

By Nicholas Reimann Photo: ANGELOS TZORTZINIS/AFP via Getty Images 04/04/22
The United Nations called on governments Monday to drastically reduce fossil fuel emissions and ramp up investment in renewable energy in what it framed as a last-ditch plan to stave off the most extreme effects of climate change, warning that a goal of limiting temperature rise to 1.5 degrees Celsius…

America’s Strategy to Secure the Supply Chain for a Robust Clean Energy Transition

By Igogo and Tsisilile 02/24/22
This document, “America’s Strategy to Secure the Supply Chain for a Robust Clean Energy Transition,” lays out the challenges and opportunities faced by the United States in the energy supply chain as well as the Federal Government plans to address these challenges and opportunities. It is accompanied by several issue-specific…

Warming weakens the night-time barrier to global fire

By Jennifer K. Balch, John T. Abatzoglou and Others 02/16/22
Night-time provides a critical window for slowing or extinguishing fires owing to the lower temperature and the lower vapour pressure deficit (VPD). However, fire danger is most often assessed based on daytime conditions, capturing what promotes fire spread rather than what impedes fire...

Updated Model Funding Policies for Higher Education

The Charles Koch Foundation has an insidious history of using its “philanthropy” to colleges and universities to shape local, state, and federal policies in ways that serve his free-market agenda while stripping power from the people. With growing awareness of the ways in which CKF buys influence over hiring, research,…

2021 was the sixth-warmest year on record for the globe

Photo: Getty Images 01/13/22
The global surface temperature for 2021 was the sixth highest since record keeping began in 1880, according to NOAA scientists. In a separate analysis of global temperature data, also released today, NASA has 2021 tying with 2018 as the sixth-warmest year on record. December’s global surface temperature tied with 2016…
