Las sequías son cada vez más severas y frecuentes, y tienen un impacto cada vez mayor en las personas, el medio ambiente y las economías de todo el mundo.

A medida que las sequías se intensifican, afectarán a un mayor número de personas y a más tierras agrícolas. Al degradar la tierra, también aceleran la desertificación y contribuyen a la pérdida de biodiversidad.

: Screwworm Confirmed in Texas

A case of the New World Screwworm (NWS) parasite has been confirmed in La Pryor, Texas. Larvae of the parasite were identified in a young calf, marking the first case in the United States in 60 years. The confirmation follows a growing spread of NWS through Mexico. Despite its presence, screwworms do not pose a serious threat to human health or food safety as direct transmission to humans is rare; the larvae only feed on live, warm-blooded animals. However, the case still poses a huge concern to the beef industry given relatively low cattle herds. The USDA has announced plans to quarantine affected animals in addition to breeding and releasing sterile NWS flies.

Prepare for an El Niño.

WMO’s latest updates confirm that El Niño conditions are developing and are set to influence global temperature and rainfall patterns, increasing the risk of extreme weather over the coming months. Although some uncertainty remains about El Niño peak strength and timing, most forecast models suggest it will be at least moderate—and possibly strong.

𝐖𝐡𝐚𝐭 𝐜𝐚𝐧 𝐰𝐞 𝐞𝐱𝐩𝐞𝐜𝐭?

Each El Niño event is unique, but it is typically associated with increased rainfall in parts of southern South America, the southern United States, parts of the Horn of Africa and central Asia, and drier conditions over Central America, northern South America, the Caribbean, Australia, Indonesia, and parts of southern Asia. During the Boreal summer, El Niño’s warm water can fuel hurricanes in the central/eastern Pacific Ocean, while it hinders hurricane formation in the Atlantic Basin.

Its effects vary depending on the intensity, duration, time of year, and how it interacts with other climate variability. Not all regions of the world are affected, and even within a region, impacts can be different.

The WMO community will continue monitoring conditions in the coming months.

Advance seasonal forecasts and are vital to save lives and cushion the impact on our economies and our communities.

🌿 are an overlooked player in climate change mitigation.

90% of their is stored underground, where their diversity helps increase the amount of organic carbon stored in roots and soils.

Because of this, and because many grasslands plants have deep and resilient root systems, their carbon stores may be more stable than those in forests, better able to withstand environmental stressors like and fires.

🌱In Johannesburg, invasive plants have degraded areas around the city’s Jukskei River.

Pines, black wattle, eucalyptus, bugweed and other invasives monopolize nutrients and outcompete local flora.

They also worsen flooding, especially in Johannesburg’s riverside informal settlements like Alexandra and Soweto. Invasive plants’ roots push out deeper-rooted indigenous species, destabilizing the soil around riverbanks. When rain hits these riverbanks, loose soil and sediment flow into the river, reducing its ability to absorb and slow floodwaters.

Aggressive invasive roots also damage drainage pipes and culverts, multiplying flood impacts. Shifts in climate and rainfall patterns are further exacerbating the problem: as temperatures increase, invasives thrive, densify and spread.

Working with local communities, initiatives like WRI’s SUNCASA project are removing invasive plants to prevent flooding and loss of biodiversity while supporting livelihoods. So far, the project has cleared invasive plants from more than 133 hectares along the Jukskei’s riverbanks while creating more than 100 jobs in the process. Workers are also reintroducing indigenous species like African olive and white stinkwood. The trees’ sturdy roots will stabilize the Jukskei’s riverbanks, increase local biodiversity and reduce the impact of flooding.

Johannesburg is also developing a Transformative Riverine Management Program, a framework and business model for investors and corporations to get involved in rehabilitating the city’s rivers, starting with the Jukskei.

From Kinshasa to Dire Dawa, cities across Africa are discovering that wetlands, trees and parks could be their strongest defense against climate change. Learn more: https://go.wri.org/africa-nbs-fb

La Tierra no es una máquina infinita.

Es un organismo vivo, complejo e interconectado, con límites que no deberíamos cruzar si queremos seguir habitándola con dignidad.

1. Integridad de la biósfera
La pérdida de especies, bosques, polinizadores y ecosistemas reduce la capacidad del planeta para regenerarse. No perdemos solo “recursos”; perdemos aliados.

2. Cambio climático
El aumento de gases de efecto invernadero altera temperaturas, lluvias, sequías, inundaciones e incendios. El clima deja de ser un patrón confiable

3. Nuevas entidades
Plásticos, pesticidas, químicos industriales y residuos tóxicos entran al suelo, al agua, al aire y a nuestros cuerpos. No todo lo que producimos puede volver sanamente a la Tierra.

4. Reducción del ozono estratosférico
La capa de ozono nos protege de la radiación ultravioleta. Su recuperación parcial demuestra que, cuando la humanidad actúa a tiempo, los sistemas pueden responder.

5. Aerosoles atmosféricos
Humo, polvo, hollín y contaminación industrial afectan la salud, las nubes, las lluvias y la calidad del aire. Lo que respiramos también forma paisaje.

6. Acidificación del océano
Los océanos absorben CO₂, pero eso cambia su química y afecta corales, moluscos, plancton y vida marina. Si el océano se debilita, también se debilita el clima.

7. Flujos bioquímicos: nitrógeno y fósforo
El exceso de fertilizantes termina en ríos y mares, generando contaminación y desequilibrios. Fertilizar no es echar más: es comprender ciclos, suelo y vida.

8. Uso del agua dulce
Cuando deforestamos cuencas, compactamos suelos o contaminamos ríos, rompemos el ciclo del agua. El reto es infiltrar, retener y cuidar cada gota.

9. Cambio del uso del suelo
Convertir bosques en monocultivos o ciudades cambia el clima local, la biodiversidad, el agua y la fertilidad. La forma en que ocupamos la tierra revela cómo pensamos.
Estos límites no están separados.
El clima afecta el agua.

⛰️Los pastizales capturan hasta el 30 % del carbono del planeta, por eso son clave en la mitigación del cambio climático.

Protejamos y restauremos los pastizales para preservar ecosistemas y reforzar la resiliencia climática.
