This is how global warming hurts kids in school, according to bombshell study
"Heat effects account for up to 13 percent of the U.S. racial achievement gap," National Bureau of Economic Research finds.

A stunning new study of U.S. high school students finds that heat waves lower their test scores, the effect is greater for minorities, and global warming is going to make things worse in the coming years.

Led by researchers from Harvard and the College Board, this National Bureau of Economic Research study, “Heat and Learning,” provides “the first evidence that cumulative heat exposure inhibits cognitive skill development and that school air conditioning can mitigate this effect.”

The study looked at almost 10 million students who took the PSAT twice (or more) from 2001 to 2014 and compared their scores with daily temperature data recorded by thousands of NOAA weather stations around the country.

Researchers found “hotter school days in the year prior to the test reduce learning, with extreme heat being particularly damaging.” Of course, global warming has already started making temperatures higher: As NASA reported in January, the five hottest years on Earth have all occurred since 2010.

At the same time, global warming has also made extreme heat waves considerably more likely, as many studies have shown.

1. No kidding!

I taught my first graders how to read a thermometer so they could measure how much we were suffering in our 90+° classroom. We had year round school and it ended at the end of July. I put my own A/C in the room but you couldn't even feel it and the district refused to put A/C in until parents petitioned the district and threatened to keep kids home (the district would lose $$$...always comes back to $$$).

2. I didn't have it quite as bad, but...

There was a summer when the A/C in our classroom building wasn't working (don't remember why). It was getting into the upper 80s. We had three floor fans in the classroom, but they didn't help very much. So the school's solution was to place large, wall unit A/Cs on rolling carts and position them in the doorways of each classroom. Think about it. A wall unit is supposed to discharge heat out the rear, so the heat was being pushed into the hallway. Not only that, but there was no seal to keep the cold air in/hot air out. If it managed to decrease the temperature in the classroom by two degrees I'd be surprised. It was also extremely noisy, so I would just shut it off when it was time for class.

I can't remember now if they ever got the central air to work that summer, but I will always remember their "solution".

3. Yep, I had to take my A/C unit out of the

slide down window each night since it wasn't the right size, do it wasn't sealed and it was a safety issue (possible break in through window by burglars). It weighed a ton and you could only feel it if you stood 6" in front of it. The fans just blow hot air around, were loud and made all the papers in the room go everywhere. I had to spray water on the wilting students all day like they were plants. NO ONE can learn in that environment!

4. No one can learn is right!

You tell people that schools are underfunded, and they think of outdated textbooks or a lack of chalk. It never dawns on them that the classroom environment is negatively affecting students as well. Classrooms with stained carpets or peeling linoleum tiles, broken desks and chairs, and heat or A/C issues do not inspire a student to excel. It might inspire them to get the hell out of there, but never to excel.

6. Correct!

During the first month of my first year that I taught first grade (a new grade and room after leaving 6th) a fellow teacher took new chairs out of my classroom after I left for the day. The following day the newish principal toured my classroom with a new school board member and a student fell backwards in her broken chair (she had a new one until it was taken overnight) and the whole class got new chairs within a week. Is this what it takes to get decent supplies? I had NO printer in my room for myself or the students for 5 years and there was no IT support on the sites. You wouldn't believe the reality of teaching when it is all based on $$$ and test scores (even for 6 year olds). The teachers you see on TV fighting for better pay since they can't afford to live on a teacher's salary is the tip of the iceberg.

5. In the heat fruits and veggies dont grow correctly. They are forced to grow too fast

So what happens is carbohydrates displace vitamins and minerals


The great nutrient collapse

The atmosphere is literally changing the food we eat, for the worse. And almost nobody is paying attention.
