Climate change threat to tropical plants

Tropical plants closer to the equator are most at risk from climate change because it is expected to become too hot for many species to germinate in the next 50 years, UNSW researchers have found.

The study discovered tropical plants do not have narrower temperature tolerances but were more at risk from global warming, because it would bring them close to their maximum seed germination temperatures.

The figures are quite shocking because by 2070, more than 20 percent of tropical plant species, we predict, will face temperatures above their upper limit, which means they won't germinate, and so can't survive."

The research was published in the journal Global Ecology and Biogeography

 

Climate has always changed and plants and animals, and humans survived, adapted, or died.
Life and death is one of natures cycles, just like climate change.
Worry is entirely man made!
Somebody, a whole bunch of somebodies, needs to get a life and a real job!

All these predictions should be required to prominently display so people aren't suckered in!

Why are fish wars heating up all over the world?
The desire for protein – and power – is helping fuel fights for territorial waters around the world. Where are these problems surfacing? And how are warming oceans making them worse?

But there has been a decline in ocean and inland fish catches, with a boom in aquaculture – fish farming – accounting for the growth in production. Even as the percentage of the world's oceans being fished has risen from 60 to 90 per cent, the actual catch has declined dramatically from 25 tonnes per 1000 kilometres travelled in the 1950s to 7 tonnes per 1000 kilometres, according to another study by the Sea Around Us.

That's not because fishing fleets or nations have become more ecologically conscious − it's because there are fewer fish to catch.

I doubt you know anything about commercial fishing. For example, which fisherie is the pictured boat designed for?

Worth about a dollar apiece at the dock. Not edible, so what is it and what is it's commercial use?

Fishing with planes.

Same fisherie as the boat and fish pictured above. Give you a clue! Rustoleum.

Different fisherie. What is this type of fishing boat and where is it used?

The bottom pictured boat, is a Great Lakes Fish Tug, a side trawler originally designed to deploy and retrieve gill nets. Small mesh gill nets were banned in 1972 and large mesh gill nets banned in 1974.
Now the boats tend trap nets mostly.

Keep thinking about the plane/ fishing boat partnership to catch that little fish in someones hand.

Okay, times up.

Climate Change Poses ‘Systemic Threat’ to the Economy, Big Investors Warn
Financial regulators should act to avoid economic disaster, according to a letter from pension funds and other investors representing almost $1 trillion in assets.

“The climate crisis poses a systemic threat to financial markets and the real economy, with significant disruptive consequences on asset valuations and our nation’s economic stability,” reads the letter, which was signed by more than three dozen pension plans, fund managers and other financial institutions that together manage almost $1 trillion in assets.

That financial threat, combined with the physical risks posed by climate change, may create “disastrous impacts the likes of which we haven’t seen before,” the letter says. It urges the Fed, the Securities and Exchange Commission and other agencies to “explicitly integrate climate change across your mandates.”

Investors worry that if regulators do not act, climate change may cause the price of some companies to fall suddenly, the effects of which may ricochet through the economy. Providing more information about that risk — for example, by requiring companies to disclose more about their greenhouse gas emissions, or which of their facilities are at risk from rising seas — could help investors make better decisions.

If Climate Change is going to be a bad thing, which I doubt, what can you do about it? Nothing!
The silly notion that the less than five percent of atmospheric CO2 contributed by humans, somehow, overides all the other climate factors and is solely responsible for Climate Change, is STUPID!

Even if you were right, and that isn't even possible, you can't even stop humans from producing CO2 either!
Stop worrying about things you can't control.
Consider how to adapt!
Humans are excellent at adapting.

Of course your REAL agenda is political. We won't let you succeed at that!

The video from Sam's linked article is also worth to be posted here I believe.

 

That's the problem with statements like the quote SamSam posted. The comparisons across a longitudinal study often aren't dealing with a static environment.

I would argue that there is some success in raising the environmental consciousness of some fishing fleets, but the regulatory and political environment is completely different today than in the nineteen fifties. Certainly you can see the impact these things have on production.

Comparing global average temperatures as measured by a few dozen recording stations across the globe in the early 20th century to a data set gathered in the mid-century by flight technology and more points of measure (more of which are in dense urban centers, where ground temperatures are inherently higher), to today's measurements done comprehensively by satellite. Making general statements for effect, without comprehensive explanation of the data collection process, is misleading.

There was, in the end of the 1900's, a statement about the emergent condition of climate change by comparing the number of named storms increasing dramatically since the decades when they first started with the practice. What the report failed to convey was that in the late sixties, the inclusion of tropical storms and pre- TS conditions were beginning to be officially named. An accurate statement that was misleading in its context.

Even if it is true that human contribution to CO2 is less than 5%, from a chemical point of view, 1 part per 20 is an enormous amount. Why couldn't that have an effect?

"and is solely responsible for Climate Change"
Is that what climate change advocates are saying? We are the sole reason for climate change? If so, I'm not with them, but I do believe human activity is making an impact. I believe it is making a measurable impact.

What I'm unsure of is what is that impact and is it necessarily bad to have climate change? As yobarnacle points out, global climate changes. Perhaps the worst thing we could do is arrest that change.

That is a valid concern. Scientists go through a very involved process to normalize temperature data from the many disparate sources. Furthermore, there are a number of teams working on building historical temperature records, each team using different analysis techniques. The value of having more than one analysis process is to see whether they arrive at similar conclusions, or whether the results are all over the board.

This web page explains a bit about the various analysis processes. I understand that each group makes public both their raw data as well as the details of their analysis procedure -- for those interested.

Global Temperature Data Sets: Overview & Comparison Table

.....The three most highly cited combined land temperature and SST [Surface Sea Temperature] data sets are NOAA's MLOST, NASA's GISTEMP, and the UK's HadCRUT. A new merged land-ocean temperature data set is available from the Berkeley Earth group. The University of Delaware and berkeleyearth.org produce global land-only surface temperature data sets. HadCRUT also has a land-only version, CRUTEM. Each group has approached the above challenges somewhat differently. The final data sets differ in their spatial coverage, spatial resolution, starting year, and degree of interpolation (only HadCRUT is uninterpolated). Most of these data sets are presented as anomalies (departures from baseline, long-term mean temperatures); only the Delaware data provide absolute temperatures for each timestep, while the other projects provide a baseline climatology to which the anomalies may be compared. Numerous comparisons of global and hemispheric mean temperature anomaly timeseries calculated from these data sets have been made, showing highly consistent variations and trends. Nonetheless, users doing more analysis than the global mean temperature will find important distinctions among the data sets.....​

I lost interest in prizes and awards meaning anything, when Obama won the Nobel prize, for what accomplishment? Got elected president! By the way, I voted for him that first term, but not the second.

 

I don't understand what your point is..?

 

Simple. Regulations and politics adversely affect fish production.
It's not a lack of fish, but an over abundance of interference.
