July was world's hottest month on record, WMO says
- TaylorGood 7y agoBeing in Florence two weeks ago when it was 104F was downright unpleasant. The locals I was with said they don’t remember it being this hot for this long either.
- csomar 7y agoI can confirm the whole Mediterranean region near Italy is going through successive heatwaves. Previously, it is not uncommon to have 40C days in the summer. But it is just a few random days. It is almost normal week/heatwave week now. Tomorrow temperature around Tunis will be in the 41-45C range. That's very uncommon for this coastal city.
- ci5er 7y agoAnd it was snowing in Denver on Memorial day. Weather is not climate, yada yada. What is it going to take to get a global consensus that we'd like to have unadjusted temperature data, not controlled by adjusters that have a funding agenda? What would it take to get a little raw data up in the house?
- mythrwy 7y agoHear Hear! A little raw data up in here please!
- NeedMoreTea 7y agoIt's probably out there. I imagine most Meteorological agencies have it available. The UK's Met Office historic has raw station readings going as far back as the station. Some go back further than others, unsurprisingly. https://www.metoffice.gov.uk/research/climate/maps-and-data/historic-station-data https://www.metoffice.gov.uk/research/climate/maps-and-data/...
- claytongulick 7y agoThere's a strong political bias here, but the data is compelling: https://realclimatescience.com/ https://realclimatescience.com/ he compares a lot of raw data to "adjusted" data. He claims that the reported temperatures are fraudulent: https://realclimatescience.com/understanding-noaa-us-temperature-fraud/ https://realclimatescience.com/understanding-noaa-us-tempera... I'm not an expert, but what I see there is pretty compelling, I've never really found a good refutation anywhere.
- demilicious 7y agoWhat’s the motive for reporting inflated temperatures?
- Daishiman 7y agoThe fact that you even claim that this is a problem means that you have no interest in a debate and are just another mindless denier, because even a cursory study of the topic at hand shows that issues of measument calibration are completely unimportant.
- ci5er 7y agoUmmm. You said what? I've been keeping track of data monthly for 30 years, and syncing with government sources of same, and you besmirch yourself. The fact is: this could well be a crisis. But governments covering data for political reasons does nothing to inspire confidence, regardless of the squealing of pantywaists. To wit- you don't spend trillions of other people's money on your night terrors
- Daishiman 7y agoSo... do you doubt the data? Do you doubt that the warmest years on record have happened in this past decade? Are you implying that calibration errors actually explain anything when the facts in question are obvious?
- ci5er 7y agoI do. I doubt all data all of the time. Why don't you? EDIT: We can actually get into it, about the data and adjustments, but ultimately everything (on both sides) is so contaminated and ugly that I don't really understand how anyone can become a zealot. From what I can tell, maybe, this year is 0.14degC LESS warm than average. You don't see that on the new, but it isn't any less credible than the sources you do. EVERYONE IS LYING ABOUT EVERYTHING ALL OF THE TIME.
- ekr 7y agoI wouldn't have guessed that humanity would fail to coordinate on global warming by this point. Blimey! How would we fare when faced with actually hard technical challenges?
- kaonashi 7y agoCoordination on a multi-national level (outside ad-hoc corporate arrangements) is an ideological non-starter for most of the world's governments.
- tenebrisalietum 7y agoWhy would you reach any other conclusion? We are a bloodthirsty, competitive, barbaric species that can't go very long without killing large numbers of ourselves in the name of various things we create and twist to fit our tribal tendencies. Certainly people can learn otherwise but it seems any institutions dedicated to peace, civility, helping others or expanding knowledge eventually get co-opted to serve baser instincts, if they aren't created under a subtext of them at the outset. Humanity is not faced with a problem. Humanity is the problem.
- hyperdunc 7y agoHumanity is only the problem from the point of view of some humans, and perhaps other species. The earth itself has no moral view on what should happen.
- danso 7y agoHow is coordinating on global warming not a hard technical challenge? Politics is inherently a hard problem. And even if we were able to extricate politics from the discussion, it's a hard problem to define the optimal benchmarks and criteria for emissions reduction, across all countries and jurisdictions. (by definition, defining these criteria for the world would necessarily involve politics)
- ekr 7y agoI meant that took global warming itself is not a difficult challenge to solve with the technology currently available. Capturing carbon is energy intensive but not impossible. But politically, the coordination problem is unsolvable. Until the effects of the warming become big enough that one of the more powerful agents involved has a clearly positive inventive gradient to actually expend that energy at a personal loss, without the cooperation of others. (Say, for instance, if a majority of US territory becomes uninhabitable due to semi-persistent fires, persistent droughts, etc, I'd expect the US to actually solve the problem irrespective of what the other powers are doing.)
- gravelc 7y agoFrightens me to think of the impact this is going to have on agricultural production over the next ten years. In cooler countries, there's sometimes benefits to warmer seasons, though biotic stresses like more insects / fungal diseases tend to dampen that. In hotter countries (many of which are developing), abiotic and biotic stresses can easily combine with bad weather events to wipe out an entire region's production. The political instability that this can and likely will cause is the greatest short-term climate change issue in my opinion. I really don't see how it can be avoided, given trans-national institutions which may have helped buffer these impacts are also at their lowest ebb since WW2.
- pojzon 7y agoClimate change migrations will be indeed very hard to solve. Either we will drop nationalism completely in the name of a single human goverment or we are going to perish (not in 10y ofcourse). Current order of power and capitalism has to die. Or we will die.
- gravelc 7y agoI highly doubt many people want to drop nationalism completely (I don't). If however agencies like the UN can no longer raise a peacekeeping force to stop conflict spreading, that becomes a serious issue. Climate change is the trigger, but our tendencies for war are what'll bring the disaster when climate change really kicks in.
- tzs 7y agoWe are now at 415 consecutive months with global temperatures above the 20th century average. That's like flipping a coin 415 times and getting heads every time.
- mythrwy 7y agoI'd love to see a source for that.
- danso 7y agoCheck out NASA's page on surface temperature analysis: https://data.giss.nasa.gov/gistemp/graphs_v4/ https://data.giss.nasa.gov/gistemp/graphs_v4/ Click the sub-heading for "Monthly Mean Global Surface Temperature", which will show the line graph/data for the temperature difference for a given month compared to the mean for 1951-1980.
- deleted 7y ago[deleted]
- mythrwy 7y agoYa.. ok. but 1951-1980 isn't the 20'th century. It's 29 years.
- sintaxi 7y agoAny average temperature comparison that excludes the 1930's and the Medieval Warm Period is most likely being deliberately deceptive.
- danso 7y agoFrom the GISS FAQ: https://data.giss.nasa.gov/gistemp/faq/index.html#q202 https://data.giss.nasa.gov/gistemp/faq/index.html#q202 > Q. Why does GISS show no data from before 1880? > A. The analysis is limited to the period since 1880 because of poor spatial coverage of stations and decreasing data quality prior to that time. Meteorological station data provide a useful indication of temperature change in the Northern Hemisphere extratropics for a few decades prior to 1880, and there are a small number of station records that extend back to previous centuries. However, we believe that analyses for these earlier years need to be carried out on a station by station basis with an attempt to discern the method and reliability of measurements at each station, a task beyond the scope of our analysis. Global studies of still earlier times depend upon incorporation of proxy measures of temperature change like tree rings, ice core data, etc.
- schintan 7y agosomeone should sponsor a big budget hollywood movie with A list stars and a top director to make a compelling movie about the disastrous potential of climate change. Will do a lot to raise awareness.
- Arbalest 7y agoSurprised it would be July, rather than January, which iirc is when the earth is closest to the sun... I'm concerned as to what that might mean for January, when we in Australia will have our Summer.
- Daishiman 7y agoThe difference in distance to the sun is much less relevant than the effects of albedo and regional features for temperature.
- flukus 7y agoJanuary is also when the southern hemisphere is closest to the sun, the southern hemisphere has a lot more water which regulates things. Which hemisphere is in summer when we're close to the sun is one of the things that's driven natural climate change in the past and one of they ways we know the current warming is an unnatural aberration.
