the changes on the increase of CO_2 in the Earth's atmosphere both in a human and in a geological scale of time; 2. the most convincing theories that justify the "skeptics'" statements; 3. the negative effects of rising CO_2 concentration in the human scale of time.F. Patania...
The World Meteorological Organization has also reported that the concentration of CO2 in the atmosphere has reached 400 ppm in 2015, and it continues to rise (Nair et al., 2022). This increase is primarily attributed to the use of fossil fuels, which contributes 91% of emitted CO2 and the...
Carbon Negative and climate positive are two similar terms. It occurs when a company removes or capture more CO2 from the atmosphere than it even emits. Then, the company has a negative amount of carbon emissions and positively impacts the climate. So let’s go deeper: to become climate posi...
in the earth, the planet absorbs heat instead of releasing it into the atmosphere: like a heated blanket that covers our planet, this is the idea ofglobal warming. As stated by NASA, some of the effects that are now occurring as a result of climate change as predicted by scientists such...
The effects of negative ions on human body mainly include the following aspects: 1. Respiratory system: negative ions can promote the formation of columnar epithelial cells of nasal mucosa, accelerate the ciliary movement of bronchial mucosa, promote the regression of edema, improve the ventilation ...
not significantly different from 0 in the first 30 years but becomes significantly negative in the recent 30 years (P < 0.05) (Fig.1e). We use the ridge regression to reduce the effects of high collinearity between water and temperature on sensitivity estimates, but the ordinary leas...
To have a >50% chance of limiting warming below 2 °C, most recent scenarios from integrated assessment models (IAMs) require large-scale deployment of negative emissions technologies (NETs). These are technologies that result in the net removal of greenhouse gases from the atmosphere. We quantif...
What is the Carbon Negative Shot™? The Carbon Negative Shot is an all-hands-on-deck call for innovation in carbon dioxide removal pathways that will capture carbon dioxide from the atmosphere or ocean and store it at gigatonne scales for less than $100/net metric tonne of carbon ...
For aiming to keep global warming well-below 2 °C and pursue efforts to limit it to 1.5 °C, as set out in the Paris Agreement, a full-fledged assessment of negative emission technologies (NETs) that remove carbon dioxide from the atmosphere is crucial to inform science-based policy making...
will require removing up to ~1000 Gtonne CO2from the atmosphere by 2100 (median estimate: 584 Gtonne)1. Nonetheless, it is still unclear whether the benefits of deploying Negative Emissions Technologies (NETs) at large scale would offset their potential damaging effects on humans and the planet...
