Enhanced rock weathering involves adding minute rock grains to cropland soils which dissolve chemically taking up carbon dioxide and releasing plant essential nutrients. Unlike other carbon removal strategies enhanced rock weathering doesn’t compete for land used to grow food or increase the demand for freshwater. Other potential benefits include reducing the use of agricultural fertilizers and pesticides, lowering the cost of food production and increasing farm profitability.
Peaking global CO2 emissions as soon as possible is crucial for limiting the risks of sea-level rise, even if global warming is limited to well below 2°C. A study now published in the journal Nature Communications analyzes for the first time the sea-level legacy until 2300 within the constraints of the Paris Agreement.
NASA's Terra satellite passed over the Southern Pacific Ocean and saw the low pressure area previously known as Tropical Cyclone Gita, affecting New Zealand.
Recent changes to vegetation cover are causing the Earth's surface to heat up. Activities like cutting down evergreen forests for agricultural expansion in the tropics create energy imbalances that lead to higher local surface temperatures and contribute to global warming.
The Fall armyworm (Spodoptera frugiperda), a lepidopteran pest that feeds on leaves and stems of as many as 100 plant species, is able to hop between different crops and cause serious damage due to its resistance to both insecticides and transgenic plants that are genetically engineered to express proteins with insecticidal action obtained from the bacterium Bacillus thuringiensis Berliner (Bt).
The reality of climate change poses a significant threat to global biodiversity. As temperatures rise, the survival of individual species will ultimately depend on their ability to adapt to changes in habitat and their interactions with other species.
