Climate Change is about more than the weather

A recent entry from San Deigo confused regional weather with climate change, and decided that we aren't getting warmer and the "so called science isn't right. Many people have this misperceptions. I wish science explained the difference in readable laymen language. Explain how weather has been charted for decades & comparing one year to another may be conversation, but it isn't science. Talk about the confusion migratory birds are experiencing and are attacking each other in competition for food. Tell them over development, and poor agriculture practices have and continues destroy habitats. Comment on the value and need for bio-diversity is, for example the need for pollinators in order to produce food, and for example bees are great pollinators and how reduced their populations are. Briefly describe how insects, mammals, retiles and birds are important in different their different 'jobs', and losing any affects everything. Tell them this isn't a local problem but world wide and the rate of change will differ. Explain about sea temperatures over decades and globally, and how it has started to get warmer faster than expected. Tell them as simply as possible how warmer sea temperatures deplete the planets ability to cool itself. That this heat is melting glaciers. Explain that commercial fishing is depleating sea life and some important creatures are starving to death because humans are greedy. Talk about how we need the glaciers to feed our streams and rivers, and because manufacturing has polluted our water sources our farming food productions is threatened as well as our own drinking water. And that we buy too much, and throw away too much and the earth and oceans have limited space for our trash. Maybe throw in the example of South west Australia where it is so hot birds & bats are dying and falling out of trees. Let them know that bats consume insects like mosoquitoes to the rate of 7,000 a night for one little bat. People don't understand that climate change isn't just about warmer but also colder like the Midwest and Northeast this winter. Since hurricanes feed off of warmer water it could be the reason we have had many severe storms, and there are more and they are coming earlier. You might throw in that people who get profits from high carbon producing substances have different concerns than most and have created a political problem. When everything becomes political it's bad news for everyone. You might explain this, but some are willfully ignorant. Thanks. I wrote this in 20 minutes. There is no editing or checking for spelling, but you, the weather people, can sort it out.


Could you please use the chemtrails to make it warmer in San Diego? It's been too cold lately.


Careful what you wish for....I'm going to assume you were being facetious.

Living at the beach in San Diego

I live at the beach in So Cal too. We don’t notice the heat changes because of the glorious Ocean breezes and reliable climate. I work from home and ride my bicycle to do all my errands... EASY to think in a bubble.
However, one mile inland is a whole different story for folks. Think about it. Inlanders have been suffering higher and longer periods of intense heat for some years now. Climate change, however created, It is very real.

As well, I fully join you in capturing rainwater !! Hello! Free water! Cistern! Anyone?

Climate Change

You are in one specific area and claim to speak for the entire world. Also, you say sea level is not rising. What is that based on? Your eyes? Well your eyes are not exactly scientifically accurate.

What are your credentials? Climate change is real and so is the fact that much of it is caused by US humans. Look to the polar ice caps, the evidence is all around you. There is solid consensus among scientists about climate change.

How dumb is that

Sea level is not going up, i can see it for myself ... dumbest statement ever. Let me just say this.. the day you can see sea level risen this earth we call home would be long gone!!!

Climate change

We they say man made climate change what they really mean is military industrial complex geoengineering. If they don't
stop soon we are all screwed. If it's not already to late.

Polar ice caps? Is that your

Polar ice caps? Is that your scientific proof? Nothing will stay frozen forever. Temperatures are rising because as the ice melts, like it has been doing since its formation, the total mass of ice becomes less, therefore, temperatures rise. This is basic physics. I learned these principles in elementary school. Cause and effect...

Rain in Northern California

Holy mackerel! This is the driest fall/winter I’ve seen for a very long time. I’m afraid we are in big trouble with our lack of rain. The animals, forrest and Human survival depends on rain. Can’t they ‘chem-trail’ clouds that will produce rain here?! They’re doing the trails anyway. Why not HELP us all out?! Any answer on this would be appreciated. It’s doable- it’s been proven!

Rain and Water

Be prepared for paying much more for water in the future. I like to keep everything green, unlike many of my neighbors who have let all landscaping just die--GROSS, and such an eyesore!! If you do not want to pay for water--just move to a place where it is just hot and dry and only cactus, rocks, and tumbleweeds! I am a San Diego native, and I have just bcome accustomed to the fact, the weather is changing-- hotter and drier. I wish others would just accept this sad fact--and stop allowing everything to just die all around them, waiting for rain!
