It is well known that CO2 concentrations above 2,000 ppm interfere with our health and efficiency, levels above 5,000 ppm are dangerous, and 10,000 ppm are life-threatening. Furthermore, in recent years there ha
not always. the average is only one measure of central tendency. depending on the nature of your data, other measures like median (the middle value) or mode (the most occurring value) might be more appropriate. if your data has extreme values or is skewed, the median or mode can provide...
What is V-Sync? V-sync was the original screen tearing solution. V-sync technology ensures that your graphics card never works at a rate higher than your monitor can handle. Even if your graphics card can average a super-high frame rate, it will be capped to match your monitor’s refres...
None of the above. The answer is: make air-conditioners better. On one calculation,replacing refrigerants(制冷剂) damaging the atmosphere would reduce total greenhouse gases equaling 90bn tonnes of CO2 by 2050. Making the units more energy-efficient could double that. By contrast, if half the...
The average human breathes out 93 kilograms of CO2 per year – however, our breathing only contributes 0.65 billion tonnes of carbon returned to the atmosphere, which is 0.01% of the amount released by fossil fuels each year Trees absorb CO2 in the atmosphere and release it in the form of ...
What is carbon neutral? Carbon neutral describes the state achieved when an entity that produces carbon emissions removes the same volume of carbon emissions from the Earth’s atmosphere. Reaching carbon neutrality can involve a variety of measures, including energy efficiency initiatives, renewable en...
While green packaging is a global trend in itself, and the sustainable product packaging solutions discussed above are part of it, here are three other kinds of innovative packaging that could emerge as key options in the future. Mushroom packaging Mushroom packaging really is made from mushrooms...
First, as described above, it is important to prioritize which measures to focus on at a subnational level given the heterogeneity of smallholder farmer production systems, the range of impact, and the feasibility of adoption. This prioritization exercise could enable the identification of clusters o...
The 2015 Paris Agreement commits countries to limit the global average temperature rise to well below 2°C above pre-industrial levels, and to aim for 1.5°C.2015年达成的《巴黎协定》中，各国政府承诺将全球平均温度控制在比前工业化水平升温2摄氏度以内，并努力达到升温1.5摄氏度以内的目标。Scientist...
【题目】What is the single most effective way toreduce greenhouse-gas emissions? Go vegetarian? Replant the Amazon? Cycle to work?None of the above. The answer is: make air-conditioners radically better. On one calculation, replacing refrigerants(制冷剂) that damage the atmosphere would reduce ...
