National Parks at Greatest Risk from Global Warming

Vanishing Joshua trees: climate change will ravage US national parks, study says America’s national parks have warmed twice as fast as the US average and could see some of the worst effects of climate change, according to a new study. The study finds that temperatures in national parks could go up 3 to 9C by 2100, under the Intergovernmental Panel on Climate Change’s worst-case scenario, which shows what could happen without policies to decrease greenhouse gas pollution. With lower emissions, temperatures could still exceed 2C (3.6F) for 58% of park land, compared to 22% of the US as a whole, according to the study. [....] Alaska parks would see the most extreme heat increases, and the US Virgin Islands parks face 28% less rainfall by the end of the century. In Glacier Bay national park, the Muir Glacier melted 640 meters between 1948 and 2000. [....] Gonzalez explained that parks at a higher elevation have a thinner atmosphere that warms faster.

Hurricane Florence and Climate Change

One of the important effects of climate change is what is happening to the jet stream.  The warming Arctic Sea has dramatically affected the jet stream.  It has been twisting its way south, and one of the results is cold winters and the American Northeast.   Another impact is on hurricanes. The dip in the jet stream is bringing cold air to the Northeast, but it also is creating an issue for hurricanes.  More hurricanes are being sent into the East Coast that would ordinarily swing up into the North Atlantic.  33 named storms (since 1851) have been within 100 miles of # Florence 's current position. None of these storms made US landfall. The closest approach was # Hurricane George (1950) - the highlighted track. However, Florence does not appear to be taking a climatological track. The problem is a blocking high forcing the hurricanes into the East Coast. Back in 2016 Francis published a study on the link between blocking highs and global warming . At the time

What People Need To Do About Global Warming

There are a lot of things people need to do to reduce their carbon footprint, for example buying an electric powered car.  However, there is something more important than that:  We have to do something not directly connected to one's carbon footprint, we have to vote.  One reason we are in the situation we're in right now is that A ‘jaw-dropping’ 15 million super-environmentalists don’t vote in the midterms The most important environmental effort you’ve probably never heard of — the Environmental Voter Project (EVP) — doesn’t talk about the environment much, if ever. But that’s because talking about the environment isn’t the solution to perhaps the biggest solvable problem the environmental movement has: a lack of voters. There are 10 to 15 million so-called “super-environmentalists” who are registered to vote in this country, but generally don’t. If they voted more consistently, it could change U.S. politics, as candidates from both parties would need to work

Global Temperatures Still Looking Bad

I posted in 2011 , So far we have an increase in .8 degrees Celsius from 1880. Fitting a linear trend from the middle of 2009 to April 2015 the RSS data projects a decadal increase of .2726 degrees, and the UAH data .6347 degrees. Thus by 2035, the RSS data suggests 1.34 Celsius global temperature, and the UAH a 2.07 Celsius. Here I've re-analyzed the UAH data, updating to 2018.  Figure 1:  Loess regression fitted to UAH global temperature data Figure 2:  Linear regression fitted to UAH global temperature data The Loess regression is more realistic than a linear regression.  Global warming deniers have pointed out the temperature "hiatus" in the 2000's and the Loess regression shows a leveling of the temperature over this years.  However, starting in 2009, the temperatures are rising again.  The temperature spikes in 1998 and 2016 are El Nino events.  Consistent with global warming, the El Nino events are also increasing their effects.
