An example of a proposed stabilization wedge is increased efficiency of electricity production #Mitigation 🔌

[Erika @Mignacca__]

One of the key risks of climate change in North America is the wildfire-induced:
-loss of ecosystem integrity
-property loss
-human mortality
#Adaptation 🔥

[Erika @Mignacca__]

Yes! Some may not even think of the economic and social impacts that climate change will have #Impacts

[Erika @Mignacca__]

@Gary49146477 RCP8.5, the high GHG emissions scenario shows a huge difference between regions! A 4 degree Celsius change can actually be a 12 degrees Celsius change in a different region such as the Northern Hemisphere #ClimatePredictions

[Erika @Mignacca__]

Due to the #WarmingEarth, the land surface is warming which leads to an early spring peak #ClimateChange 🌸

[Erika @Mignacca__]

The Earth's current temperature is the highest it has been in about 1,000 years and this is caused by the increase in carbon dioxide due to human activity #Carbon 🌎☀️👨‍🏭

[Erika @Mignacca__]

Yes! And this excludes anthropogenic phenomena - this has always been part of the Earth's natural energy flow #EarthThermodynamics

[Carina Marro @MarroCarina]

@SofiaConstanto1 Yes! once these GHGs absorb IR, they heat up and then emit radiation in all directions. They send some energy back down towards the Earth. This acts as a blanket over the surface of the Earth! #Lesson11

[Erika @Mignacca__]

@PanagiotisMav12 Which raises sea levels and that helps answer the question "is the Earth warming?" #WarmingEarth 🌎

[Erika @Mignacca__]

@ZuberiNoureen CO is especially sensitive to:

-infants
-elderly people
-people with heart and/or respiratory diseases

#AirPollutants

[Erika @Mignacca__]

The Gulf War oil spill in 1991 was the biggest oil spill in history, spilling 1.5 million tonnes of oil #WaterPollution

[Erika @Mignacca__]

Carbon monoxide is formed when there is not enough oxygen during combustion to form carbon dioxide #AirPollutants

[Nicholas Giannoumis @NGiannoumis]

Incomplete combustion of the carbon that leads to the formation of carbon monoxide. 2C+O2= 2CO. #Lesson10

[Erika @Mignacca__]

Planes fly in the stratosphere because there is a steady wind zone! I remember learning about this in high school! #Lesson10 ✈️☁️

[Erika @Mignacca__]

When looking for good insulation, we want a high R-value meaning the material is NOT good at transferring heat #Heating 🔥

[Erika @Mignacca__]

#WaterHeating is the second highest use of energy in the residential sector in Canada. The three types of water heating are:

1. Hot water tanks 🌊
2. Tankless
3. Solar ☀️

[Erika @Mignacca__]

While reading about #Appliances, I realized that a lot of the tips mentioned are not followed in my house!😳 #Lesson9 was very informative!

[Erika @Mignacca__]

@YingFan60365202 Also, avoid overfilling the dryer and avoid over-drying your clothes! #Lesson9

[Erika @Mignacca__]

The Yucca Mountain project was approved but has now been put on hold because originally, it was demanded that it be safe for 10,000 years. The laws then changed to a demand of a million years which is more than scientific assessment can prove #RadioactiveWaste

[Leanne Lemish @LeannePHYS273]

Internationally believed that nuclear energy waste should be stored underground yet no country has this method in place.... hmmmmm

[Erika @Mignacca__]

Coal and oil have much higher death rates per amount of energy produced despite the misconception that nuclear energy has the highest #Lesson8

[Erika @Mignacca__]

@MarroCarina Agreed :( these deaths were caused by long term problems and cancers associated with this radiation #NuclearAccidents

[Erika @Mignacca__]

Every lesson I learn a new surprising fact... #NuclearEnergy (through fission) can release 1 million times more energy per atom than #FossilFuels!
