Geoengineering Is The Controversial Plan To Stop Climate Change

Every day, humankind pumps greenhouse gases into the atmosphere, which slowly warm the planet and threaten our future. What if we could fight global warming the same way? That's what some scientists are trying to figure out. The concept is called geoengineering, and while it could pose risks we haven't even begun to fathom, it could also be the solution to our climate troubles.

7 eating habits that we know are good for us:

1. Eat plenty of vegetables and fruits – Some countries are very specific about the number of servings of fruits and vegetables that we should consume daily, for example Greece says six, Costa Rica and Iceland say five. Canada even specifies the colors of vegetables to consume (one dark green and one orange vegetable a day). Serving sizes can vary by country; however, all guidelines recommend eating plenty of fresh vegetables and fruits on a daily basis.

2. Watch your intake of fats– Said in different ways, most guidelines make mention of reducing solid, saturated fats and give recommendations for replacing animal fats with vegetable oils. In Greece, olive oil is recommended, in Viet Nam it is sesame or peanut oil – demonstrating the importance of availability and cultural preference in each country’s guidelines.3. Cut back on foods and beverages high in sugar – It is generally agreed upon that processed sugar is harmful to our health. The guidelines in every country recommend to maint…

Humans are a massive minority on Earth. Why don't we act like it?

Humans are a massive minority on Earth. Why don't we act like it?

Most of us, including scientists, are blind to the full scope of the living world. This was illustrated by an informal survey which asked biologists and ecologists from elite universities two questions. In terms of mass, is the living world mostly composed of animals, plants or bacteria? And is there more global biomass on land or in the oceans? The majority of them answered both questions incorrectly.In an age of unparalleled access to information, this is a glaring gap in our knowledge. We are now equipped to close it. I joined colleagues from the Weizmann Institute in Israel and the California Institute of Technology to estimate the biomass of all kingdoms of life on Earth. The results were published in the journal of the American National Academy of Sciences, and were widely (and more digestibly) covered by the popular press.It required years of work, collecting and integrating information from hundreds of previ…

Chart of the day: These countries create most of the world’s CO2 emissions

With CO2 levels on the rise, being able to track global emissions is crucial. Image: REUTERS/Regis Duvignau Just two countries, China and the US, are responsible for more than 40% of the world’s CO2 emissions. With CO2 levels still on the rise, being able to track the global emissions hotspots is becoming more important than ever. Before the industrial revolution, levels of atmospheric CO2 were around 280 parts per million (ppm). By 2013, that level had breached the 400ppm mark for the first time. On 3 June 2019 it stood at 414.40ppm. Fifteen countries are responsible for more than two thirds of global CO2 emissions. Image: Visual Capitalist There are huge disparities between the world’s top 15 CO2 emissions-generating countries. China creates almost double the emissions of second-placed US, which is in turn responsible for more than twice the level of third-placed India.
