"Women climate scientists are connected, productive, and successful but have shorter careers" Accessible, though paywalled at doi.org/10.1073/pnas... 🧪
Women may be discouraged from becoming climate scientists if they perceive the field as male-biased, but little is known about gender in climate science. An analysis of over 400,000 publications shows that men and women in climate science have similar degrees of productivity, success, and connectedness with other scientists, and publish in high-prestige journals at similar rates. However, the analysis also shows that women have marginally shorter careers, which leads to cumulatively fewer publications. 

Scholars have long been concerned about gender representation in scientific research but there has been little work on gender differences in participation and performance in climate science, a field that engages with both male-majority disciplines (e.g., geosciences, engineering) and female-majority disciplines (e.g., life sciences, medical science). This has implications for both gender equity and viewpoint representation. Sampling over 400,000 publications and a similar number of authors, we examine gender differences in several scholarly outcomes including publication count, career survival, coauthor gender, journal status, and mean citation count. We find men and women are similarly productive, successful, and connected, though women have shorter research careers and thus fewer papers. We also find gender homophily effects in collaboration, but no evidence of gender bias in peer review.

CHAPTER 13
Downsizing the National Oceanic and Atmospheric Administration
Valerie J. Karplus and Costa Samaras
Carnegie Mellon University

The National Oceanic and Atmospheric Administration (NOAA) plays a vital role in the United States' ability to anticipate and respond to short- and long-term threats to security, health, and resilience. NOAA is an agency within the Department of Commerce that tracks and predicts changes in weather, climate, coastal lands, and oceans, enabling actions that prevent damage to life and property. From avoiding deaths due to extreme weather, to averting collisions of objects in space, to informing decisions of farmers and fishers, NOAA offices constantly generate trusted, open information that has profound, tangible benefits for people and businesses. NOAA is facing the potential of losing more than 25% of its current $6 billion budget.' Without NOAA, the US economy will be no match for everyday events, and woefully unprepared for climate change.
As one of the world's premier weather and climate change research agencies, NOAA provides data, tools, and information to help advance the scientific understanding of climate change and its impacts.? Essential weather data used widely across both the public and private sectors in the US originates with NOAA.' Helping the public and businesses understand how heat,* drought,' floods," sea level rise,' and other hazards are changing can allow communities to better prepare for climate change and manage impacts. However, risk from climate impacts is a combination of how hazards change, if people and infrastructure are in harm's way of these hazards, and how vulnerable these communities are to damages when extreme weather shows up. NOAA connects these concepts and serves as a critical climate resilience agency, enabling communities to assess climate risks and take action.® NOAA provides on-the-ground resources for communities to build up the local workforce and capacity

If you think climate change has gotten worse during your lifetime, you're right and there's a good reason. If you're Gen X like me, more than 3/4 of fossil fuel CO₂ emissions have occurred in your lifetime. Even if you're a Millennial, it's at least half. 📊: @neilrkaye.bsky.social
A horizontal bar chart titled "Percentage of Global fossil fuel emissions (since 1751) occurring in my lifetime." The chart shows how much of the total historical global fossil fuel emissions have occurred within the lifetime of individuals of different ages, from 5 to 100 years old. The vertical axis on the left lists ages in increments of 5 years, from age 5 at the top to age 100 at the bottom. The horizontal axis represents the percentage of fossil fuel emissions, marked in 10% increments from 10% to 90%.

The black bars represent the proportion of fossil fuel emissions that have occurred during each age group's lifetime. The bars increase in length as the age increases, meaning older individuals have lived through a larger percentage of the cumulative emissions since 1751.

Three specific age groups are highlighted with red bars and white text annotations:

Age 30: "if you are 30 it is more than 50%"

Age 50: "if you are 50 it is about 75%"

Age 85: "if you are 85 it is about 90%"

The source of the data is cited at the bottom: "CDIAC and globalcarbonproject.org." The graphic is credited to "@neilrkaye."
