World Tapir Day is celebrated on 27 April each year and exists to raise awareness about the species of tapir that inhabit Central and South America and Southeast Asia and to raise funds to purchase land to protect it from human encroachment.

Tapirs are large herbivorous mammals that inhabit jungle and forest regions of South America, Central America, and Southeast Asia. As large herbivores, tapirs are invariably the first species affected by human encroachment into their territory, and amongst the last to return to regrowth forest. They require substantial tracts of undisturbed land to maintain a genetically-diverse population. Tapirs inhabit jungles, grasslands, swamps and cloud forests, yet each is threatened by human activity – be that mining, palm oil plantations, roads or settlements. They form an important part of the ecosystem as seed dispersers, and form one of the oldest surviving genera in the animal kingdom. Despite their size, history and ecological importance, tapirs remain one of the least recognised species of animals. In comparison with other animals, tapirs feature little in the collective consciousness and are frequently misidentified by zoo visitors. Even in their home ranges, tapirs receive little attention, with exotic species featuring more prominently in zoos, children’s books and the media. The plight of tapirs is symbolic for the wider threat to their habitats specifically, and the world’s ecology in general. The decline of tapir populations is indicative of the general health of their ranges; their disappearance from their home ranges often marks a point of ‘no return’ for the natural environment. The destruction of forests into small, isolated enclaves and the encroachment of human activity into pristine forests affects all native species. However, as the largest – yet perhaps the quietest – of animals in their ranges, tapirs disappear without trace with countless other species. All tapirs are endangered species. Saving tapirs helps to save the rainforest. Saving rainforests helps to save the planet and prevent climate change.

Dynamic and steric sea-level changes due to a collapsing AMOC in the Community Earth System Model – publicatie / publication

AMOC

Klimaatmodellen laten een verzwakking van de Atlantische oceaanstroming (AMOC) zien door de opwarming van de aarde, de beperkte directe waarnemingen van deze stroming en de waargenomen verandering in zeewatertemperatuur suggereren dat deze verzwakking al gaande is.

Dit gaat eerst geleidelijk, maar als de AMOC een kantelpunt bereikt, gaat het snel: binnen 50 tot 100 jaar valt de stroming dan vrijwel geheel stil. Het onderzoek ‘Dynamic and steric sea-level changes due to a collapsing AMOC in the Community Earth System Model‘ van het KNMI en de Universiteit Utrecht geeft voor het eerst een goede inschatting van hoe het tempo van zeespiegelstijging langs de Nederlandse kust wordt beïnvloed als dat gebeurt.

COP31 Bike Ride

COP31 Bike Ride

In 2026, the COP31 Bike Ride is uniting passionate adventurers from across the globe as they journey by bicycle and sailboat from the Amazonian city of Belém, Brazil, the host of COP30 to Antalya, Turkiye, the host of COP31, that will start on November 9th.

Their goal? Underline the benefits of everyday cycling to reduce carbon emissions, a goal they pursue by bringing to the COP ten proposals of cycling policies to be included in the countries’ climate plans. With a main start point from Belém the site of the previous COP, the ride features multiple starting points across continents, including Europe, Central Asia, and Africa. Participants carry, as an olympic flame, a symbolic banner and navigate diverse terrains, from urban centers to remote regions, and sail across open waters to reach their destinations. Given the unique distance and number of cyclists, this ride should break again several world records.

EGU General Assembly 2026

EGU26

The European Geosciences Union (EGU) is a non-profit international union in the fields of Earth, planetary, and space sciences whose vision is to “realise a sustainable and just future for humanity and for the planet“.

The organisation has headquarters in Munich, Germany. Membership is open to individuals who are professionally engaged in or associated with these fields and related studies, including students, early career scientists and retired seniors. It also organises several topical meetings, as well training events and summer schools, and provides support and funding for numerous education and outreach activities. Its most prominent event is the EGU General Assembly, an annual conference that brings together scientists from all over the world. The meeting’s sessions cover a wide range of topics, including volcanology, planetary exploration, the Earth’s internal structure and atmosphere, climate change, and renewable energies. The EGU has 22 scientific divisions that reflect the interdisciplinary nature of the organisation.

#WorldIPDay World Intellectual Property Day / Werelddag voor Intellectueel Eigendom 2026

World Intellectual Property Day is observed annually on 26 April.

The event was established by the World Intellectual Property Organization (WIPO) in 2000 to “raise awareness of how patents, copyright, trademarks and designs impact on daily life” and “to celebrate creativity, and the contribution made by creators and innovators to the development of societies across the globe”. 26 April was chosen as the date for World Intellectual Property Day because it coincides with the date on which the Convention Establishing the World Intellectual Property Organization entered into force in 1970. This event has been criticized by a number of activists and scholars as one-sided propaganda in favor of traditional copyright, ignoring alternatives related to copyleft and the free culture movement.

Vroege Vogels Radio | 26 april 2026 (Radio 1 NPO)

Vroege Vogels

Vroege Vogels is een live-radioprogramma, tv-programma en online community van BNNVARA over natuur en milieu.

In het radioprogramma wordt het gesproken woord omlijst door licht klassieke muziek en salonmuziek. Het radioprogramma werd in 1978 voor het eerst uitgezonden door de VARA en is een van de langst lopende en best beluisterde radioprogramma’s van de publieke omroep. Het wordt elke zondagmorgen uitgezonden tussen 07:00 en 10:00 op NPO Radio 1. De beginmuziek is een bewerking van Vivaldi’s “Piccolo Concerto in C major” (RV 443).

Op twee locaties zagen vogelringers rare sterfgevallen en neurologische verschijnselen bij zwaluwen, de vogels bleken veel insecticiden op hun veren te hebben. Wie aan mummies denkt, dwaalt af naar het oude Egypte. Maar voor mummiekatten, -otters en zelfs mensen kan je ook gewoon in Nederland blijven. Deel twee van het Nationaal Vogelconcert met een hoofdrol voor het geluid van de eider. En verder: biodiversiteit op het erf, het lied van Agilouz, trek van de winde, Schaatsenrijder is het waterdiertje van 2026 en de column is van Bibi Dumon Tak. Vroege Vogels Radio wordt gepresenteerd door Jan van Poppel vanuit het Groene Huis in Amersfoort.
