Seriously Linda? For you to say that you really don't understand, do you? One can look at any temperature graph since the industrial revolution to see the steady climb and it's acceleration, along with industrial production. Look at the average mean temperatures for overly heated days of not only summer, but spring and fall also, we had flowers blooming in February all over the place, not just flower but the trees also, we've had a premature birth of spring! the length of our summer keeps expanding, summer is a toll on the environment when it's too long and too hot, God forbid we don't get the rainy days, like some places Linda, it's called a drought, it's called a tinderbox for forests. How many miles and miles have been burnt up on the west coast alone in the past decade? I'll tell you...
Oct 3, 2019 - Over the past 10 years, there were an average of 67,000 wildfires annually and an average of 7.0 million acres burned annually. In 2018, 58,083 wildfires burned 8.8 million acres nationwide, the sixth-largest figure on record in terms of acreage burned.
Of course algae increases in the peak summertime heat conditions, so now imagine that with the burner turned up, yes there is only one conclusion, rising Temps,will increase the condition.
Every year since 2000, an average of 72,400 wildfires burned an average of 7.0million acres. This figure is nearly double the average annual acreage burned in the 1990s.
This is just in the US not the world, now we can see how Australia will impact the world statistics. The slight variations on a yearly matter are insignificant, due to the length of time it takes to regrow a forest, decades and decades.

Oh I understand, B, we just have differing views....
One can also look at any graph to see cyclic change of warming trends to ice age trends
too..Not c*****e c****e but w*****r p*****ns, which is why I asked you my question on if w*****r p*****ns are c*****e c****e~~ Since you didn’t answer that, would you do so here??
Here lets for example use the horrific loss of the Amazon forests...Recall my comment on how the El Niño years impact our w*****r p*****ns...I love National Geograph, yet sgain not a news article~~
See how much of the Amazon is burning, how it compares to other years
Deforestation rates across the Amazon have spiked this year, driving the devastating blazes.
Thousands of fires are burning across a southern swath of the Amazon. They belch smoke and soot, blanketing those who live downwind with thick, dirty air, hurting wildlife in their path and destroying part of one the most important carbon storehouses left on the planet.
About 76,000 fires were burning across the Brazilian Amazon at last official count, an increase of over 80 percent over the same time period last year, according to data from Brazil’s National Institute for Space Research (INPE). Since then, even more fires have appeared in the satellite imagery that scientists use to assess the extent and intensity of burning, and they expect the number to increase over coming months as the dry season intensifies.
The burning season
From June to December, the southern Amazon Basin dries out, and fires can become a concern. Most are caused by human activity, especially clearing lands for farming.

The fires themselves are destructive and devastating, but their primary cause is more concerning, says Ane Alencar, the director of science at the Amazon Environmental Research Institute (IPAM).
“The majority of the fires we’re seeing now are because of deforestation,” she says. “It’s crazy. We reduced deforestation by almost 65 percent in the past. We proved that we could do that. And now we’re going backwards.”
Why now? And how bad is it compared to the past?
So far in 2019, the number of fires burning across the Amazon is higher than at any point since 2010, which was a particularly bad year of drought, says Ruth DeFries, an expert on sustainable development at Columbia University. By last week, about 7,000 square miles of the forest were in flames, an area just smaller than the size of New Jersey.
Most fires observed in the region are caused by humans. Many are set in previously cleared lands in order to quickly remove any excess vegetation that has popped up. Others are set in land that is still in the process of being cleared, in order to make more open land for crops or cattle.
Farmers and ranchers down forest earlier in the year and leave the felled trees to dry out. Once the fallen trees have desiccated, they set them on fire, leaving behind an open swath of land ready for agricultural activity.
But fires have been worse in the past—because deforestation was more acute.
Amazon deforestation peaked in late 1990s and early 2000s. In the worst phases of those peak deforestation periods, over 10,000 square miles of forest could be cut down in a year, much of that cleared area converted directly to cropland for soy or grazing for cattle. In some years, like in 1998 and 2005, that deforestation activity coincided with major El Niño droughts, and fires were abundant and widespread.
Counting the Amazon Fires
The Amazon did not evolve to burn, but for centuries, fire has been used to clear space in the rainforest for agricultural crops, from soybeans to palm to cattle. Deforestation often leads to fire. In Brazil—which controls the majority of the vast forest—regulations were put into place over a decade ago to curb the expanse of deforestation, but these rules have been loosened by the new Brazilian administration, and consequently fires are spiking.

Before regulations
The first implementation of forest legislation in Brazil took place in 1965, but it wasn’t until 2006 that the Public Forest Management Law was passed, aimed at reducing the amount of deforestation. In 2008 new measures were put in place to further protect the forest.
After regulations
Strong El Niño events cause droughts in the region, creating ideal conditions for burning. El Niño years have high fire counts, even after intentional deforestation rates dropped.
Now
The new administration has actively encouraged more agricultural activity and development and has greatly reduced enforcement of illegal deforestation within the Amazon. There are 80% more fires now than this same time last year.
