Currently, about half the world's population relies on synthetic fertilizers produced from fossil fuels. Before you go blocking traffic and glueing yourself to something you better have a solution to ensure that these people won't starve in your plan to save the planet. #climate
The Haber-Bosch process is a chemical process that converts nitrogen gas (N₂) from the air and hydrogen gas (H₂) from natural gas or other hydrocarbon sources into ammonia (NH₃). It was developed in the early 20th century and is one of the most important industrial processes.
This comment by @IPCC_CH is incorrect. There has been NO increase in the frequency or intensity of extreme weather events 👇. The increase from the '70s to the late 90's is an artifact of increased global interconnectivity and better reporting. In fact, the @UN Office of...
...Disaster Risk Reduction (@UNDRR) was started in late 1999. In reality, in the last 25 years, the number of natural disasters and extreme weather events has DECLINED. Let's look at costs and damage...
The losses associated with natural disasters normalized to GDP, to account for population growth and increases in infrastructure in disaster-prone areas, have also DECLINED. Let's look at deaths...
Why do geologists think that fossil fuels are the remains of fossilized organisms?
1) Geological evidence: Fossil fuels are found in sedimentary rocks that are typically formed from the accumulation of sediments at the bottom of oceans or lakes. 1/5
2) Chemical composition: Fossil fuels are primarily composed of hydrocarbons, which are molecules made up of hydrogen and carbon atoms. These molecules are similar in composition to the organic material found in living organisms, such as plants and animals. 2/5
3) Isotopic signatures: The carbon isotopic signature of fossil fuels is similar to that found in living organisms. This isotopic ratios is due to the fact that plants and animals preferentially use Carbon-12 during photosynthesis and respiration. 3/5
What role does Earth's magnetosphere play in climate change?
The Earth's magnetosphere plays an important role in protecting the planet from harmful solar radiation and charged particles. However, its direct impact on the Earth's climate is not yet fully understood. 1/5
One way in which the magnetosphere can indirectly affect climate is by modulating the amount of cosmic rays that reach the Earth's surface. Cosmic rays are high-energy particles that originate from outside our solar system and can impact cloud formation by ionizing... 2/5
...molecules in the atmosphere. Changes in cosmic ray flux can therefore potentially influence cloud cover and thus the Earth's climate. Additionally, the Earth's magnetic field can affect the distribution and circulation of charged particles in the atmosphere... 3/5
Climate proxies are indirect measurements of past climate conditions that can provide insights into how the Earth's climate has changed over time. However, there are several sources of error associated with climate proxies that can limit their accuracy and reliability. 1/7
One source of error is natural variability. Climate proxies are influenced by natural fluctuations in the Earth's climate system, such as changes in solar radiation, volcanic activity, and ocean currents. These natural variations can make it difficult to distinguish... 2/7
...between changes in climate that are due to human activities, such as greenhouse gas emissions, and those that are due to natural factors. Another source of error is the quality of the proxy data itself. Some types of climate proxies, such as tree rings or ice cores... 3/7
