Does the amount of energy released from burning of fossil fuels have a measurable impact on global warming?

Asked by: Melissa Whaley No, it’s not currently measurable. Human primary non-renewable energy consumption is about 15TW – and pretty much all of that goes into low-grade heat in the ocean surface and the atmosphere. How does fossil fuels affect global warming? What is the link between fossil fuels and climate change? When fossil fuels

If it rains harder, does it mean the rain’s duration will be shorter?

Asked by: Melissa Whaley The intensity of a rainstorm does not actually cause the duration of the precipitation to be shorter. What happens if it rains too hard? Heavy rainfall can lead to numerous hazards, for example: flooding, including risk to human life, damage to buildings and infrastructure, and loss of crops and livestock. landslides,

Prevailing winds between 30 to 60 degrees latitude

Asked by: Courtney Vairaganthan WesterliesThe westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude. What are the prevailing winds between 30 and 60 and latitude? Prevailing Westerlies: From 30-60 degrees latitude (aka Westerlies). Tropical Easterlies: From 0-30 degrees latitude (aka

How does water still exist on the Earth?

Asked by: Courtney Vairaganthan Liquid water, which is necessary for life as we know it, continues to exist on the surface of Earth because the planet is at a distance, known as the habitable zone, far enough from the Sun that it does not lose its water, but not so far that low temperatures cause

Impacts of high-altitude emission of greenhouse gases (GHG) compared to sea level GHG emissions

Asked by: Alexandra Blanco Is the greenhouse effect weaker at higher altitudes? Thus, the absorbing power of a greenhouse gas decreases with altitude, because there are fewer molecules to do the absorbing. At some altitude, the absorption for any particular wavelength will become so weak that the radiation will simply pass through that layer (and

The spiraling cyclone track – Cyclone Nathan

Asked by: Alexandra Blanco What are the 4 types of cyclones? There are 4 types of cyclones and they are: Tropical cyclone. Polar cyclone. Mesocyclone. Extratropical cyclone. What is a cat 5 cyclone? Extremely dangerous with widespread destruction. A category five cyclone’s strongest winds are VERY DESTRUCTIVE winds with typical gusts over open flat land

Does the feel of temperature change, when you’re in two different places

Asked by: Sheryl Siebert Can the same temperature feel different in different places? In fact, the very numbers of thermal comfort aren’t even universal. There are dozens of ways to measure what a hot summer day actually feels like; different countries do it differently, and how you measure affects how we communicate and understand risk.

How to predict when contrails are likely to form over a specific location using public data?

Asked by: Sheryl Siebert How well can Persistent contrails be predicted? Contrails are persistent when R H i ≥ 1 . Thus, the summary of this analysis is that while contrail formation can be forecasted quite reliably, their much more important property of persistence cannot currently be predicted reliably. Which part of the atmosphere are

1.5° above what?

Asked by: Jonathan Dean What is the 1.5 degree target? The 1.5 °C target is the goal of the Paris Agreement, which calls for countries to take concerted climate action to reduce greenhouse gas emissions in order to limit global warming. What is 1.5 degrees above pre-industrial levels? But in terms of how much warming

How to calculate rate of change of temperature with pressure in Earth’s troposhere?

Asked by: Jonathan Dean What is the rate of change in temperature in the troposphere? As the density of the gases in this layer decrease with height, the air becomes thinner. Therefore, the temperature in the troposphere also decreases with height in response. As one climbs higher, the temperature drops from an average around 62°F
