Global worming makes the season changes. Spring and Fall become shorter, and Summer and Winter is getting longer than before.

*4% of Mammals are Wild + 4% of Energy is Renewable + 2% of Energy is Solar & Wind*
Total greenhouse gases are up 45% in 30 years. 66% of us will live in water stressed areas by 2025. Water stress will threaten 50% of thermal power capacity
. North Euro solar panels work 11% of the time. North Euro onshore wind turbines work 22% of the time. North Euro offshore turbines work 30% of the time. Offshore Texas turbine work 35% of the time. 4% of global energy is renewable. 2% of global energy is solar and wind. Electricity is 20% of total global energy. Fossil fuels have been 80% of global energy for over 25 years. 15% of global energy will be renewable by 2040. 30% of global energy will be renewable by 2050. The F-35 fighter jet works 10% of the time. Most solar panels will be un-recyclable garbage. We have to stop burning 50% of fossil fuels in 10 years to survive runaway habitat collapse and hothouse extinction.
Europe burns 50% of its renewable electricity
Europe burns 80% of the world’s wood pellets for “renewable” electricity
Europe burns 80% of recycled plastic & paper for electricity
Europe burns 50% of its palm oil shipments in cars & trucks
In 10 years the US cut emissions more than Europe switching from coal to gas than they did investing in renewable energy
Weather = flash floods + flash fires + flash mobs + flash infections
Climate = 30 years of it
From 1971-2018 oceans took up 89% of the 358 zeta joules of net energy from the sun, ice took up 4% of it, land took 6% of it and the lower atmosphere only took 1%
From 1971-2018 solar heating averaged 0.47 watts/m²
From 2010-2018 heating went up to 0.87 watts/m² = rapid acceleration
To force rapid heating back down from 0.87 w/m² we have to cut C02
from 410 ppm to 353 ppm. But we have to go below 350
to 300 ppm CO2 to be safe.
*Mass Extinction Numbers*
500 years ago there were so many cod fish that John Cabot thought they would life his ship out of the water
400 years ago there were more Caribbean sea turtles by weight than buffalo on the plains
300 years ago Passenger pigeon migrations would block out the noon day sun
We do not live long enough to notice mass extinctions
97% of great fresh water species gone since 1970 ( Guardian 2019 )
96% of mammals are livestock and human by weight ( Ecowatch 2018 )
96% of tigers gone in 100 years ( IFL Science 2019 )
90% of elephants gone in 100 years ( Hurriet 2019 )
90% of lions gone in 100 years ( African Impact 2019 )
90% of Leatherback sea turtles gone since 1980 ( Earth Watch undated )
90% of Monarch Butterflies gone in 20 years ( Inhabitat 2014 )
80% of Antarctic Krill gone in 30 years ( Research Gate 2005 )
77% of Eastern lowland gorillas gone since 1996 ( Treehugger 2020 )
68% of world’s wildlife has been wiped out since 1970 ( Mongabay 2020 )
50% of Marine vertebrates gone since 1970 ( WWF 2015 )
50% of Great Barrier Reef gone since 1985 ( Live Science 2012 )
40% of Giraffes gone since 1990 ( NRDC 2019 )
40% less insects in next 30 years ( PNAS 2019 )
4% of mammals are wildlife ( Vegan News 2020 )
700 Marine Species Might Go Extinct Because of Plastic ( Green Planet 2019 )
500 vertebrate species of less than 1,000 individuals ( PNAS 2020 )
500 species of animal have gone extinct since 1900 ( RD 2019 )

Very simplified but yes I’m with it! Just wish our leaders weren’t bickering half the time – guess it’s up to us the people to make it so.
