Women, non-native English speakers & those form low-income countries are disadvantaged in science but by how much? We found that women with non-English first languages from low-income countries publish up to 70% fewer in English than their counterparts. 1/5 doi.org/10.1371/jour... #languagebarriers
Scientific productivity gap based on English-language peer-reviewed papers. Shown are the maximum % differences in the number of peer-reviewed papers published by female native English speakers from a high-income country (-45%), female non-native English speakers from a high-income country (-60%), and female non-native English speakers from a lower-middle income country (-70%), compared to male native English speakers from a high-income country (red flag).

I wrote my new Nature World View in this transition — one last reflection before leaving Colombia. It explains why inequities persist in science, even when dressed up as inclusion, and why we must stop mistaking access for change. 👉 rdcu.be/eGEun

Equity in science is a beautiful lie — and I’m done pretending | Nature
Science isn’t really moving towards equity; institutions are just perfecting the appearance of equity. We need to build an alternative system. Science isn’t really moving towards equity; institutions are just perfecting the appearance of equity. We need to build an alternative system.

A new study in Nature Climate Change shows contrasting biological production trends over land and ocean. Led by Yulong Zhang at Duke. I am glad to be part of the team. The last study that looked at production over both land and ocean was published in 1998. www.nature.com/articles/s41...

Tree methane exchange in a changing world
Nature Reviews Earth & Environment, Published online: 19 June 2025; doi:10.1038/s43017-025-00692-9Tree methane exchange is an important component of the terrestrial and global methane budget. This Perspective explores the mechanisms underlying why wetland trees are a net source of methane to the atmosphere and upland trees are a net sink, and the effect environmental changes will have on these processes.

New in @sciencemagazine, a review on Scaling plant responses to heat (www.science.org/doi/10.1126/...). Increased temperature along with acute heat waves threaten the ability of terrestrial vegetation to act as a carbon sink, but predicting how plants will respond to heat is challenging.

Deforestation in Colombia increased in 2024 after two years of decline, just as the environment ministry had warned since April last year. Experts fear that the increase will continue in 2025 and that armed groups will continue to hinder the progress of conservation strategies with communities.

Our new research shows that forest recovery from tree mortality has slowed in recent decades. This reduction is primarily associated with rising temperatures and increased water scarcity. Recovery of forest canopy water content lags behind that of vegetation greenness www.nature.com/articles/s41...

I've released the 2025 update of the WGLC global lightning dataset today. Daily and monthly data lightning density and stroke energy covering the period 2010-2024 are now available! doi.org/10.5281/zeno...
World map of average density of lightning strokes from the period 2010-2024. The greatest density of lightning is seen in the tropics and subtropics of the Americas, Africa, and island Southeast Asia. The most lightning is in northeastern Colombia and Panama. There is almost no lightning in the Arctic and none at all in Antarctica.

Studying environmental sciences is about studying our life support system. It should not be partisan.
NOAA, along with other US scientific agencies like the National Science Foundation and the Environmental Protection Agency, has faced scrutiny by the Trump administration for its role in sharing information about climate change. References to "global warming" and "climate change" have been removed from thousands of government web pages in the wake of orders from Trump to roll back climate action. And NOAA has reportedly been ordered to review grants that include terms such as
"climate", "carbon" and "greenhouse gas".
The Trump administration
is widely expected to soon lay off employees at the agency.
In that context, Ho is sympathetic to the reasons climate scientists may not want to mention climate change, and to focus on something like air pollution instead. "It's a safe thing to mention because it has nothing to do with climate change," he says. "Air pollution is not one of the key words."
"There's a lot of uncertainty, there's a lot of fear," Ho adds. "And it shouldn't be this way. Studying environmental sciences is about studying our life support system."
