Will global warming start to have an effect on this generation or the next generation?Um, global warming stopped in 1998.Yes, I know; you’ve seen those graphs that show temperatures still rising.Actually, the hottest temperatures this century occurred back in 1936.So why does the data say it’s still getting warmer? Well, the data doesn’t, but the data doesn’t fit the narrative, so NASA and NOAA “correct” the data. They’ve published such correct graphs three times, and every time they do, it gets colder in ‘36, and warmer and warmer currently.It shouldn’t take you long to find archived images of their “creeping data”. But actual, original source data shows that, no, it’s pretty steady the past 2 decades, possibly cooling.We are in the middle of a glaciation, but presently enjoying a warmer respite called an interglacial.You should pray it gets warmer. Warm weather (and more moisture in the air), plus abundant CO2 is awesome for plant life; just ask greenhouse owners.It’s the coming cold you should be worried about. Cold weather kills more people, animals, and crops than heatwaves.For a very detailed exposition on all of this, read:Dave Burton's answer to Did 30,000 scientists declare that climate change is a hoax?
How are we causing global warming if volcanoes and other natural disasters cause nearly all CO2 emissions?
Your point is, in many ways, a valid one. It is true that nature, through natural disasters as well as the mere existence of the biosphere and hydrosphere, releases CO2 emissions at a pace that humanity will never compete with. However, with the notable exceptions of stupendous natural disasters that have caused drastic if short lived changes to the climate, the earth naturally reabsorbs CO2 at much the same rate as it is naturally released. The issue becomes that, since the industrial revolution, there has been a drastic increase in CO2 emissions caused by human activities, as well as a rapid destruction of the wild life necessary to reabsorb CO2. Though relatively small, these human contributions lack any natural means of counterbalancing them. An appropriate metaphor would be a line at a DMV. Let us say that, in a set amount of time, 10 people arrive at the DMV to do business, and 10 people are serviced. There are, of course, times and days where this will not be true(natural disasters), and inevitably the ability of the workers to work effectively will change depending on normal workplace factors (natural climate change, resulting in extremes but only very gradually), but for the foreseeable future, the average is 10 in and 10 out, resulting in an even balance. However, if the the average number of people arriving is increased to 12, and the number serviced is reduced to 9, you will see a very long line develop comparatively quickly (human caused climate change) and without sufficient time for the management of the DMV to develop a way to counteract the above trend (climate change occurring at too quickly for wildlife, or humanity for that matter, to adjust or evolve).
According to NOAA, 2017 was the third warmest year on record and the warmest without an El Nino.2017 ranks for land and ocean surface temperatures:Land, global: 3rdOcean, global: 3rdLand, northern hemisphere: 3rdOcean, northern hemisphere: 3rdLand, southern hemisphere: 3rdOcean, southern hemisphere: 3rdNorth America: 6thUnited States, contiguous: 3rdSouth America: 2ndArgentina: 1stEurope: 5thPortugal: 2ndGermany: 8thUK: 5thFrance: 5thAustria: 8thAfrica: 4thAsia: 3rdHong Kong: 3rdOceania: 6thNew Zealand: 5thAustralia: 3rdRecords generally go back to 1880 but specific nations vary.You may have experienced a very cold winter, and NOAA’s records support that, depending on where you may live. Global warming, however, makes no specific predictions regarding seasonal or regional warming. This is global warming, a trend averaged over the entire surface of the Earth over a period of multiple decades. The United States, for example, only comprises two percent of the Earth’s surface, and winter is only a quarter of the year.Further, atmospheric temperatures are very temperamental from year to year. The vast majority of heat is stored in the ocean, under the surface, so atmospheric temperatures depend greatly upon interactions between the atmosphere and ocean. Trends in atmospheric warming are only generally considered valid if they can be established over a minimum period of 30 years. One year’s temperatures cannot legitimately be used to verify or dismiss global warming.Nevertheless, 2017 was by no means one of the coldest years.Global Climate Report - Annual 2017
