Read, but not comprehend. And the article you cited is not about "birds dropping out ot sky from heat stroke", but birds breeding better in forested areas than farmlands.
For nearly all of the last 200 million years, CO2 levels were higher than the current 400ppm level, yet bird populations were even higher. And during the early Carboniferous, CO2 levels topped 8,000ppm (20X today's levels) yet that was perhaps the most biologically diverse period in earth's history.
LOL, what? According to official UN FAO statistics, the three largest fisheries are the Indian Ocean (12.22M tons), the Pacific Central (13.26M tons) and the Pacific Northwest (19.1M tons). But despite the "Northwest" term, that last fishery stretches all the way down to Vietnam, South China, and the Northern Philippines. All three fisheries are primarily warm-water regions.
And these figures don't count "inland waters". In that category, the top ten fisheries are, in order from largest to smallest:
India
China
Bangladesh
Myanmar
Uganda
Indonesia
Cambodia
Tanzania
Nigeria
Egypt
None of which are "cold water" regions.
The fishing figures you said for marine catch couldn't find. Parts of Indian Ocean cooler as well. Lots of overfishing and poor monitoring in the warmer waters .
Those warmer water fish are also being affected by the warming of the water , acification , lower oxygen levels.
I did find 40% of world catch is pacific ocean, China , Russian and other nationalities head to Southern waters to poach , they hide and obfuscate
Western lakes , water ways are for recreational fishing . it's great Africans can fish there lakes as Africa struggles with sufficient proteins, add beans and peanuts etc. But again not all rainbows and roses, with uneven rainfall etc.
Mankind is resourceful and with marine farms for shrimp , algae , they can look after itself mostly.
That oceans are warming affects fish not just for humans , but animals and birds in the food chain . The oxygen cycle etc a lot of it's from the ocean with phytoplankton at least 50%
Anyway thanks I enjoy my quick reading just now on the WWW
As we are entering the fastest known warming periods , it is going to bring about instabilities and the continuation of the sixth extinction period which is man made , at least 100 times normal background rate.
There are going to be winners and losers . Whether you care about the poor, biodiversity or just your grand children , the science is mostly settled that CO2 ( known as greenhouse gas easily over a 160 years ago and undisputed still ) we have an invested interest to reduce it.
That actually cost to reduce it, is not even going to be that much of a hardship. Humans can adapt to some extra prices , by changing habits , using new ways quite easily. We adapted to everything else easily enough.
Fish farms is a good example , though they have definite cons, it's a good source of protein , employment and can be made sustainable
World population should peak not too far away and start declining as well
Like you said coal fired power stations have their drawbacks
Doing things a smarter way is a win win. No one except greedy people want polluted water ways , huge toxic land fills etc ( especially as many vulnerable to floods etc )
Solar farms are now being mult land use.
People are finding ways to deter bird strikes on buildings or turbines . Sometimes maybe placement was wrong.
You from what you said live in Ireland, myself in NZ, we are very lucky indeed. Us chatting won't change anything. Most action now is not at a personal level , but governmental
Plus it's a multi faceted problem , you have to address other concerns as well , eg poverty, lack of education especially for girls. To stop population growth and get buy in
Some of the things happening is crazy, chopping down Amazon for little short term reward, those cattle farmers need the Amazon for rainfall . As it produces a huge "sky" river
Rhino poachers make practically not a lot. Instead the profit goes to the middlemen and crime bosses
This period of human history will seem wasteful and out of balance.
Sustainability will be just so accepted as the norm in the future
If it wasn't for the innocent , nature- I would not care that much, as some of us are making our own bed
