Contre la destruction de l'océan, du climat et des pêcheurs artisans
Anthropogenic emissions drive global-scale warming yet the temperature increase relative to pre-industrial levels is uncertain. Using 300 years of ocean mixed-layer temperature records preserved in sclerosponge carbonate skeletons, we demonstrate that industrial-era warming began in the mid-1860s, more than 80 years earlier than instrumental sea surface temperature records. The Sr/Ca palaeothermometer was calibrated against ‘modern’ (post-1963) highly correlated (R2 = 0.91) instrumental records of global sea surface temperatures, with the pre-industrial defined by nearly constant (<±0.1 °C) temperatures from 1700 to the early 1860s. Increasing ocean and land-air temperatures overlap until the late twentieth century, when the land began warming at nearly twice the rate of the surface oceans. Hotter land temperatures, together with the earlier onset of industrial-era warming, indicate that global warming was already 1.7 ± 0.1 °C above pre-industrial levels by 2020. Our result is 0.5 °C higher than IPCC estim

Een brede, kale strook doorklieft de Maya-jungle in de buurt van Izamal, een gemeente in de staat Yucatán in het zuidoosten van Mexico. Het is sectie drie van de 1500 kilometer lange Tren Maya die straks dwars door het oerwoud zal sporen. De Mayatrein is het belangrijkste megaproject van de regering van de linkse president Andrés Manuel López Obrador.
Russian energy company Rosneft announced the discovery of a massive oil resource in the Pechora Sea with an estimated 82 million tons of oil. A drilling campaign in the Medynsko-Varandeysky area led to the discovery of the field. “During the tests, a free flow of oil was obtained with a maximum flow rate of 220 cubic meters a day,” the company’s statement read on Wednesday, noting that the “oil is light, low-sulfur, low viscosity.” According to Rosneft, the exploratory work in the Pechora Sea confirmed the "substantial oil potential of the Timan-Pechora province on the shelf and served as the foundation for continuing the study and development of the region."
Center of Bicycle Technology Maya Pedal is a Guatemalan NGO based in San Andrés Itzapa. We accept bikes donated from the USA and Canada which we either recondition to sell, or we use the components to build a range of "Bicimaquinas", (pedal powered machines).
Door de klimaatopwarming krijgt Jemen te maken met intense droogtes én zware overstromingen. Duizenden jaren geleden beschermde een netwerk van aquaducten en reservoirs de havenstad Aden tegen beide.

Als de aarde verder opwarmt, zal werk in de buitenlucht op steeds meer plekken ter wereld onmogelijk worden, blijkt uit nieuw onderzoek. Vooral in woestijnachtige gebieden, zoals de Golfregio, kan dit tot enorme economische verliezen leiden en zelfs mensenlevens kosten.
In het vlijmscherpe essay ‘Consumeren als konijnen’ veegt Soumaya Majdoub (VUB) de hardnekkige mythe van de aardbol dat overbevolking de motor van de klimaatverstoring is. Green Growth en geboortebeperking zijn slechts schijnoplossingen, gestoeld op verkeerde veronderstellingen en bangmakerij.
