    Over the years I have posted anual information on temperature and other trends indicating Global Warming. This thread will deal with the trends in 2019.

    July was the hottest month ever on Earth. Now massive wildfires are burning across the globe.

    July was the hottest month ever on Earth. Now massive wildfires are burning across the globe.

    DENVER – Wildfires are burning across the globe, clogging the sky with smoke from Alaska to the Amazon, and scientists say it's no coincidence that July was the warmest-ever month recorded on Earth.

    The fires have forced evacuations worldwide, most recently on Spain's Canary Islands, where more than 8,000 people have been forced to flee. Smoke from some of the fires is so bad satellites can see it from space, blanketing large portions of South America and the Arctic.

    Climate scientists say the fires are partly the result of a world growing warmer, making it easier for flames to spread.

    “In these conditions, it is easier for wildfires to grow and to be more long-lived,” said Mark Parrington, a senior scientist in the Copernicus Atmosphere Monitoring Service at the European Centre for Medium-Range Weather Forecasts.

    The Amazon rain forest fires can be seen from space, and NASA can see these fires from space. Veuer’s Keri Lumm reports. Buzz60

    The average global temperature in July was 1.71 degrees F above the 20th-century average of 60.4 degrees, making it the hottest July in the 140-year record, according to scientists at NOAA’s National Centers for Environmental Information.

    The previous hottest month on record was July 2016. Nine of the 10 hottest recorded Julys have occurred since 2005; the last five years have ranked as the five hottest. Last month was also the 43rd consecutive July and 415th consecutive month with above-average global temperatures.

    Parrington said it's not possible to draw direct connections between hotter weather and more wildfires, citing human activity. For instance, although there are big fires currently burning in the Amazon, the past 20 years have generally seen a reduction in forest fires there, he said. But now the fires are the worst they've been since at least 2010, based on initial data, he said.

    Climate experts say there's always going to be regional variations – the U.S. has had a below-average wildfire year following 2018's deadly blazes across California – but the overall trend is toward more extreme weather fueled by a hotter climate.

    The Arctic's boreal forests are particularly at risk, said Rick Thoman, a climate specialist with the Fairbanks-based Alaska Center for Climate Assessment and Policy. Like Parrington, he said it's not a simple connection between hotter weather and more fires, but said the conditions for fires are growing more frequent in the north.

    "It's a reinforcing loop: The more fires you have, the more land you open up, so in future years you're going to warm that land more because the trees aren't there to shade it, which will in turn melt permafrost, which will then release carbon and methane, which are greenhouse gases, which contribute to warmer summers and more fires," Thoman said.

    Baloney. Take a look at the temperatures of the Roman warming period (where you could plant date trees in Greece) and the medieval warm period (when you could, and many did, plant wine grapes in England and Germany)

    ........and in 1976.

    Good grief, doesn't ANYBODY fact check?

    Not to mention that pretty much any July in the time of the dinosaurs was warmer than this one.

    Great googly moogly.

    This summarizes your post very well. ou have to look at the trends over years, and the cycles of warming and cooling. The ice core records of the Arctic and Antarctic tke the warming periods like you mention in Rome well. As far as the millions of years in the past the dinosaurs lived scientist understand the cycles of warming and cooling over millions of years, actually not relevant to the current trends related specifically to the rise in CO2 in the atmosphere since the industrial revolution..

    If someone says to you, "It's cyclical - it's happened before."
    Just ask, "WHEN did this happen before?"
    And yes, the climate HAS been like this before, like several
    hundred thousand years ago, and when animals could just
    get up and move to another location.

    You are back pedaling.

    Your claim was that July was the hottest month ever on earth.

    that's EVER.

    On earth.

    That is demonstrably untrue.

    Don't try to evade that one.

    As I stated previously the cycles of warming and cooling are well recorded in the ice cores, and the sediments over millions of years, and the causes are well understood.

    Actually I did not make the claim, actually I will make the claim more accurately as in recorded temperature records in recent history is more accurate. The article is stuck in unfortunate layman's language, but it is accurate for as long as we have records.

    More complete and accurate records up to this time in 2019

    All the global temperature records set so far in 2019

    All the global temperature records broken in 2019, so far
    Data: NASA GISS; Graphic: Harry Stevens/Axios
    The world's top 5 warmest years on record have occurred since 2014 — and it's almost certain that 2019 will be added to this list as well.

    Why it matters: Such trends are indicative of long-term global warming due to human activities such as burning fossil fuels for energy and transportation, cutting down forests for agriculture and other purposes. Only 1 of the top 20 warmest years on record since instrument data began in 1880 took place before the year 2000. With greenhouse gas concentrations in the air at their highest level in 3 million years, the odds favor more record-shattering years in the future.

    Many countries have been setting new milestones for monthly record warmth, as is the world at large. Here are some of 2019's noteworthy temperature records:

    Monthly rankings
    Monthly temperature records are based on estimates from a number of different organizations, including NOAA and NASA.

    • January: Third-warmest January, per NOAA
    • February: Fifth-warmest February, per NOAA
    • March: Third-warmest March
      • NOAA and Europe's Copernicus Climate Service ranked March as the 2nd-warmest on record, while NASA and the Japan Meteorological Agency ranked the month slightly lower as the 3rd-warmest March on record.
    • April: Second-warmest April
      • April saw a global temperature anomaly of 0.99ºC, or 1.8ºF, above the 20th century average, per NASA.
    • July: Passed August 2016 at the hottest-ever month on record by 0.14ºF, according to the NOAA and Europe's Copernicus Climate Service.
    National records
    Aside from global trends, some individual continents and countries are setting records of their own. Here are a few national records that have been broken this year, some of which still need to be verified in order to officially enter the record books:

    • Angola saw its hottest temperature ever measured for any month in February.
    • Australia shattered its record for the hottest summer ever, propelling its national average temperature to a new all-time high.
      • January had an average temperature that was 5.2°F (2.91°C) above the 1961–1990 average — the first time any month has topped 86°F (30°C), nationally.
    • Belgium broke its all-time record at 40.6°C (105°F) on July 25.
    • France saw its hottest June day on June 26 with an average high of 94.8°F (34.8°C).
      • France also broke its all-time record of 44.1°C (111.4°F) on June 28 as the temperature rose to 44.3°C (111.7°F) in Carpentras.
    • Germany broke its record of 41.5°C (106.7°F) on July 25, according to the German Weather Service, and reported by DPA News.
    • Kenya saw its highest April temperature on April 20 in Mandera, which hit 41.6ºC (106.88ºF).
    • The Netherlands broke its all-time record on July 25 at 4o.4°C (104.7°F).
    • Poland and Germany each set a new respective June temperature record.
    • Russia set its hottest May temperature on record in Yelabuga at 32.9ºC (91.22ºF) on May 13.
    • Vietnam broke its record for hottest May temperature on May 20 at 42.8ºC (109.04ºF) in Con Cuông.

    Facts have been checked. We are talking GLOBAL WARMING. The Medieval Warm period was mostly in Europe.

    Why didn't you fact check?

    Yeah, but as my linked showed it was only slightly warmer in Seattle. AGW busted. Checkmate Atheists!

    Of course one can always find areas where there were not record temperatures. That is why the icecaps are so useful since they are indicative of climate over broad regions. The "temperatures" that they record are determined by the temperatures where the water evaporated from the oceans that makes their ice caps.

    There is, you realize, a rather large difference between 'recorded history' (about 150 years) and 'ever in the history of the earth.'

    Wait.
    what?

    Europe isn't part of the earth?

    Was it on the underside of the earth's four cornered flatness, or something?

    Good heavens, just when I think that I have seen the silliest statement imaginable.......

    As it happened, the medieval warm period affected North America a great deal. it caused major droughts on the mainland and Alaska warmed up.

    Just when I thought y'all couldn't GET more entertaining....

    You did not pay attention. Yes, Europe is part of the Earth, but it is not the whole Earth. Warming in one region does not mean warming over the entire Earth. Here look at this graph:

    [​IMG]

    As up can see the entire Earth was only slightly warmer during the Medieval Warm Period. Look at the far right side of the graph. You will see that it is noticeably warmer today than it was back then.

    Once again, think GLOBAL not local.

    Of course, but ice cores represent excellent records going back thousands of years compared with our recorded temperature records are consistent with the cycles we experience in the last 150 years or so, and sediment and rock cors provide excellent records going back millions of years. Cycles have been with the earth since the beginning millions of years.

    The graph posted by @Subduction Zone illustrates recent history well.

    I've been wondering about that myself lately.

    Releasing theoretical models without telling anybody the facts behind the model.

    Cant explain the facts for making the theoretical models that would make any sense for the most part.

    Can't show anybody repeatable results to back up the models.

    Yeah I do wonder today.
