The weather is not melting cars. But there was a big fire in Tucson and the heat from the fire melted plastic parts on a bunch of cars in the parking lot. The pictures in this article fairly clearly match the cars, parking lot, and background building in the picture you attached.
So, are cars in Arizona melting in the heat? A few that were unfortunately ...
This study, by a nuclear advocacy group, is based on treating a cubic meter of used solar panels as being equivalent to a cubic meter of spent uranium.
Just digging around the links, I find the following:
Yes, slashdot's description is pretty accurate.
"Environmental progress" is a pro-nuclear advocacy group. The website initially presents as a general ...
No, rivers and other land-based sources account for 10-12%
Sources of ocean-based plastic pollution
Almost 90% of plastic debris that pollutes ocean water, which translates to 5.6 million tons, comes from ocean-based sources. Merchant ships expel cargo, sewage, used medical equipment, and other types of waste that contain plastic ...
The Constitution of the Kingdom of Bhutan, Article 5, paragraph 3:
The Government shall ensure that, in order to conserve the
country’s natural resources and to prevent degradation of the
ecosystem, a minimum of sixty percent of Bhutan’s total land
shall be maintained under forest cover for all time.
This is pretty much true, and has happened multiple times in the past. In fact, they were introduced in the German intraday market in 2007.
For example, the same situation occurred in May 2014, when prices for energy became negative.
However, the reason that renewable energy had temporarily negative prices is that it is difficult to store energy, and that ...
The cartoon seems to originate from Resources Spent on Consumption of Animals (citing to a video from Bite Size Vegan) which gives slightly more detail:
1 lb of beef = 55 square feet of forest (45-55 trees)
One year using NO paper saves 8.51 trees vs. foregoing 1 lb of beef, which saves 45-55 trees
One year eating no beef saves 3,432 trees
The reason for this discrepancy is because the data from the Umweltbundesamt includes construction and demolition waste (see figure below and surrounding text on your linked webpage) whereas the data from the EPA "does not include everything that is landfilled in MSW, or nonhazardous, landfills, such as construction and demolition (C&D) debris, municipal ...
Blackle actually cite a real reference to backup their claims. Credit to them!
On their About page they quote a line from a Energy Use and Power Levels in New Monitors and Personal Computers, Roberson et al, Environmental Energy Technologies Division,

Yes, this figure is consistent with estimates from 20 years ago.
The 1995 paper Endangered Ecosystems of the United States:
A Preliminary Assessment of Loss and Degradation collates some relevant estimates from the literature in Appendix A.
50 United States
85% of original primary (virgin) forest destroyed by late 1980's (Postel and Ryan 1991).
This calculation is pretty much worst-case for the bicycle. It doesn't take into account that food production has actually stored CO2 from the atmosphere which is now just released back, while fuel was originally underground and its CO2 is added to the carbon cycle. Neither does it take into account mercury/other emissions, nor the wear-and-tear in cars and ...

There are some (in)famous experiments done by Rupert Sheldrake who claims that a so-called "morphogenetic" field is responsible for this sort of thing. Alas, his experiments had quite sloppy methodology.
The feeling itself is real, as most here will testify. But it has nothing to do with being actually stared at/observed.
Yes, public buses appear to be worse than cars, at least based on the data I found for the US.
(At present and on average. See the "Caveats" section for a discussion about this.)
Edit: the answer from DJClayworth appears to be based on the same information, I just noticed. bbc.co.uk just links to the overview for the Dept. of Energy report, but doesn't ...
To get a littler closer to the horse's mouth -- the news article is about the Living Planet Report 2018 as published by the WWF (the wildlife people, not the wrestling people.)
On page 7 of that report we have:
The Living Planet Index also tracks the state of global biodiversity by measuring the population abundance of thousands of vertebrate species ...
Yes, a dishwasher almost always uses less water than manual washing.
According to a study published by the University of Bonn, both the energy and water consumption of a dishwasher is better:

Yes, the 'ecological footprint' can be useful in suggesting areas where humanity has unsustainable practices which need to be improved.
However, the footprint is usually presented in a very misleading way, as it dramatically oversimplifies sustainability and implies that all efforts to achieve sustainability are equal. If such a score was used as a basis ...
That "myth" was started by Newsweek and irresponsible journalism more than any peer reviewed publications. Time was equally responsible. However, if you look at the number of actual papers published on the subjects of climate change, you will see that most were actually more concerned about warming:
Or viewed another way:
Keep in mind that climate change ...
According to Popular Mechanics, who I assume probably did their homework, it's worthwhile recycling newspaper and a couple of types of plastic in addition to aluminum (that aluminum recycling is wise should be utterly uncontroversial--aluminum refining is amazing, but not a low-energy process!). There was an article in the Economist a few years ago that ...
No, that’s not true. In fact,
Humans emit 100 times more CO2 than volcanoes. [source]
so it’s the exact opposite.
For example, in 2008 humans emitted about 36 billion metric tons of CO2. In that same year, the highest (!) estimates for all volcanoes combined (submarine volcanoes included) were just 270 million metric tons (Gerlach, 2010).
The claim to ...

Yes, people are exposed to more radiation from coal power plants than from nuclear power plants:
Dosage comparison from Wikipedia:
According to U.S. NCRP reports [source says 92 and 95], population exposure from 1000-MWe power plants amounts to
490 person-rem/year for coal power plants and
4.8 person-rem/year for nuclear plants during normal ...
In a word, no. Weather stations are (as their names suggest) designed for collecting information for weather forecasting (i.e. short term variations in temperature, precipitation etc.), they were never intended for collecting information for climate research (long term statistical behaviour of the weather). As a result, the instruments used tend to have ...
Cornell psychologist Edward Titchener (who studied under Wundt) tested the ability to detect unseen staring and published in Science (1898). His conclusion: people cannot detect when they are being stared at, though a great many believe they can.
Though others have tested this `ability' over the years (e.g., Rupert Sheldrake), the results are mixed, and ...
A search on https://tineye.com led me to this tweet by @AyeElleJay with the caption "Slimmmmm! Arizona weather real different 😩" against that image.
Replies to the tweet questioned its validity, and a user named @TheMutHouse replied "this is from a recent fire in tucson, the neighboring apartment buildings cars were melted."
I'm not sure if it's the ...
No, The Register has misrepresented the story.
There are several parts to this question. The summary is:
"Peak Wind" is a myth: there is nothing similar in wind to how hydrocarbon stocks will get to such a depletion point that annual production will decline inexorably thereafter.

David JC MacKay's excellent book Sustainable Energy - without the hot air (free ebook), has a nice chapter on public transport.
At its best, shared public transport is far more energy-efficient than individual car-driving.

The act of shedding leaves is a response to an environmental pressure (dehydration). In the northern hemisphere trees 'recall' the nitrogen and carbon present in their leaves in the fall in preparation for winter, to prevent dehydration of the tree during the dry period(s).
For your case in India, the 'dry season' is between March-May, and as a result the ...
The short answer is that no, electric cars are most definitely not at a thermodynamic disadvantage compared to a combustion engine. Quite the reverse, they have the advantage.
Electric cars are about 4x as efficient as fossil-fuelled combustion engines, tank-to-wheel: ICE engine efficiency is around 20%. Electric engines tend to be around 80-90%. And the ...
What is the claim?
Are you asking about total biomass, biodiversity, regional populations, ...?
Are you asking about specific areas / countries, or worldwide (which will be hard to exactly quantify)?
Are you asking about whether we have wiped out at least 60%, or are you asking whether a ballpark figure of about 60% is plausible?

TL;DR: Yes, a plant-based diet does use less resources than a meat-based diet. However, neither diet is currently sustainable.
